Our experience with silicone in rhinomentoplasty.

Based on a review of the literature and our own experience, we propose criteria for the site of implantation that, in our eyes, is suitable for a silicon implant or a cartilage transplant. Special interest is focused on rhinoplasty and chin augmentation, as both determine the facial profile of the patient. During the last 17 years we have treated 443 patients with augmentation rhinoplasty, of whom 360 received autologous ear cartilage grafts and 83 received autologous rib cartilage grafts. At the same time we saw 30 patients requiring removal of artificial implant materials that were used by other surgeons for rhinoplasty augmentation purposes. Since 1986 we have performed 60 chin augmentations with anatomically shaped silicone implants (McGhan), of which 40 patients had a combined rhinomentoplasty done.

Endoscopic excision for postrhinoplasty mucous cyst of the nose.

Mucous cysts formation following a rhinoplasty is a rare complication. Only 16 cases have been reported. The cysts seem to arise from mucosal remnants left in the subcutaneous layer and must be distinguished from other complications causing postoperative swelling of the nose, such as foreign body, paraffinoma and bony or cartilagineous fragments. We describe two cases of dorsal mucous cysts following rhinoplasty, provide a review of the concerning literature and discuss the removal of the lesions by nasal endoscopy. Nasal endoscopy allows excellent exposure of the operative field, without the need of open rhinoplasty technique, allowing fast healing, minor swelling and no external scar.

[Combined nasal approach: maxilla-premaxilla approach and external approach].

INTRODUCTION: A major aim of septo-rhinoplasty is the treatment of the internal and external nasal defects overall. We describe our technique with a combined external approach and maxilla-premaxilla approach in one surgical process. We present our functional and aesthetic results. METHODS: We analyse 16 patients that underwent septo-rhinoplasty using a combined approach; external approach and maxilla-premaxilla approach between 1999 and 2003. Anterior active rhinomanometry (RAA) and Anderson's scale to grade nose defects were performed before the operation and once again a year later. Furthermore, patients answered a visual analogical scale in order to know if they had noticed an improvement in nasal a year after the operation. RESULTS: RAA showed significant improvement in nose flow by 100 Pa pressure with a total flow mean of 730 cm3/s after surgery. After the operation, the majority of patients felt a definitive improvement in their nasal respiration. Scores on Anderson's scale of nose defects showed a significant improvement in nasal defects after surgery p<0.001. We achieved also a significant improvement for each pyramidal subunit. There were no complications in the healing of incisions neither patients complained of them. CONCLUSION: Nasal combined approach; external approach and maxilla-premaxilla approach in septo-rhinoplasty is a safe technique and allows functional and aesthetic improvement in nose defects, mainly in nasal base defects combined with septal defects.

[Remodeling of the nasal lobule using cartilaginous grafts on tip projection].

OBJECTIVES: Nasal tip projetion and definition are essential parameters which should be considered in the preoperative rhinoplasty plan. Jonhson and Toriumi have defined a technique of rhinoplasty to restructure the lobule using columellar strut and tip grafts. The aim of this study was to define the influence of this procedure on nasal tip projection, using the Goode method (objective measurement of the tip projection). METHODS: Forty patients underwent primary rhinoplasty, by open approach, with remodeling of the lobule using cartilagenous grafts, according to Jonhson and Torium technique. Goode ratio was calculated to assess tip projection preoperatively and postoperatively, based on photographic analysis. Moreover, postoperatively, all patients were clinically evaluated at 2, 4 and 6 months, and based on photographs of face at 2 and 6 months. RESULTS: Five hypoprojected preoperative nasal tips (Goode ratio (GR): 0,45 to 0,51) had a normal nasal tip projection postoperatively (GR: 0,55 to 0,59). Among the eight normal projected preoperative nasal tips (GR: 0,56 to 0,60), six had a normal postoperative nasal tip projection while two showed a hyperprojection (GR: 0,62 and 0,63). Among the 27 hyperprojected preoperative nasal tips (GR: 0,62 to 0,75), 17 showed a normal projection of the nasal tip postoperatively while 10 remained hyperprojected despite a decreased Goode ratio. CONCLUSION: Restructuration of the lobule, using cartilagenous grafts, is a reliable and reproducible technique allowing satisfying aesthetic results and objective measurements of the changes in nasal tip projection using the Goode method.

Imaging and surgical approach of nasal dermoids.

OBJECTIVE: Determine the most accurate and cost effective radiographic evaluation for nasal dermoids. Determine the best surgical approach for excision of nasal dermoids. DESIGN: Retrospective chart review. SETTING: Division of Pediatric Otolaryngology, Children's Hospital and Health Center, San Diego, California. PARTICIPANTS: All patients with nasal dermoids evaluated and treated from 1990 to 2000. INTERVENTION: Preoperative radiographic evaluation and surgical excision. OUTCOME MEASURES: Accuracy of CT and MRI correlated with surgical findings and results. RESULTS: Ten patients were identified with the diagnosis of nasal dermoid. The age at diagnosis ranged from 0 to 24 months, with a mean of 3 months. Six children presented with masses located at the glabella, three patients presented with masses located at the nasal dorsum and one presented with a mass at the nasal tip. Six children underwent a computed tomogram with contrast of the head. Seven children underwent a MRI study of the head. Three children underwent an initial CT followed by MRI. Twenty percent of children were found to have intracranial extension. CT scan accurately diagnosed intracranial extension in one case, was indeterminate in a second case and falsely positive in a third case. MRI correctly diagnosed intracranial extension in two cases and had no false positive or false negative results. No children were found to have associated intracranial anomalies. In the early years of the review, a simple excision was made over the mass with blunt and sharp dissection for removal. (An external rhinoplasty incision is now used with better exposure and improved cosmetic results.) In cases with intracranial communication, a combined approach of external rhinoplasty and craniotomy was used. CONCLUSIONS: MRI alone is the most cost effective and accurate means of evaluating nasal dermoids and is essential for preoperative planning. The surgical approach of choice is external rhinoplasty for both cosmetic reasons and exposure of nasal dermoids with and without intracranial extension.

Aesthetics for the next millennium.

The approach of a new millenium provides us, as rhinoplasty surgeons, the opportunity to reflect on where we are and where we are going. Aesthetically, there are several trends that are evident today. The first is the desire for a natural, unoperated appearance to the final rhinoplasty result. Second, is that our patient population continues to be more racially diverse; Caucasian normative standards of facial analysis are no longer sufficient. What is required is a broader understanding of ethnically specific facial features. Third, the standard values of facial and nasal analysis are derived from population means. If we desire to create beauty, these standards may not be adequate. Beauty is an ill-defined concept that is obvious to the observer and recognized cross-culturally, however, it is difficult to quantify. To consistently achieve beautiful rhinoplasty results, we must start with an understanding of what our aesthetic ideals should be. This has yet to be satisfactorily defined for all racial groups and remains a challenge for the future.

Augmentation mentoplasty using a custom-design wire cage.

Mentoplasty is often a complimentary procedure to rhinoplasty. At least 25% of all rhinoplasty patients may need a chin implant to balance facial features better. Augmentation mentoplasty using alloplastic implants such as silicone, rubber, or other materials provides a simple approach to the treatment of the hypoplastic chin. Although these types of implants are readily available in developed countries, there are parts of the world where they are unavailable or quite expensive. The authors have developed a chin implant made of wire that is available throughout the world and is custom designed to the mentum of the patient after a cephalometric evaluation. This technique has been used in 125 patients along with rhinoplasty over the last 20 years at our institution. In an initial series of 8 patients, the prosthesis became displaced and was removed in 2 patients. Since then, a new radiographic technique has been developed to demonstrate the shape of the mentum before surgery and new bone formation after surgery. By using this special radiographic technique, it was possible to detect four types of mentum before surgery and to construct a custom-design wire cage according to this shape. The prosthesis is constructed by an orthodontist according to the cephalometric measurements and shape of the mentum. By using the buccal approach, a pocket is prepared subperiosteally and a wire cage is inserted. In the last 20 cases, the wire cage was filled with diced cartilage wrapped with Surgicel. The results were esthetically satisfactory in most patients. After the shape of the wire prosthesis was modified to conform to the shape of the underlying bone better, no displacement of the prosthesis has been experienced. In 3 patients, it was necessary to remove the prosthesis when new tissue formation began to fill the prosthesis. These specimens were examined histologically, and the regenerating tissue was found to be connective tissue with a thin layer of bone formation. Most patients could be followed up for only 3 to 12 years. In all patients, the results have been consistent and the procedure has been safe.

Nasal augmentation using calcium phosphate cement.

This report describes a simple technique for augmentation rhinoplasty using calcium phosphate cement paste for postoperative and posttraumatic nasal deformities. This biomaterial was used to correct traumatic nasal bone deformity in one patient and for augmentation rhinoplasty after removal of the nasal implant in two patients. These patients were followed for a minimum 6 months and a maximum of 26 months. The esthetic results were satisfactory with no complication. Calcium phosphate cement consisting of alpha-tricalcium phosphate, dicalcium phosphate dibasic, and tetracalcium phosphate monoxide has been used for bone replacement and augmentation because of its good biocompatibility and osteoconductivity. This technique is easy and safe. It seems to be a suitable material for augmentation rhinoplasty in the Orient. Its long-term safety and reliability require proof with longer follow-up periods, however.

Immediate reconstruction of extruded alloplastic nasal implants with irradiated homograft costal cartilage.

OBJECTIVE: To describe a novel surgical protocol for the management of patients presenting with extruded nasal implants. STUDY DESIGN: Retrospective chart review. METHODS: Analysis of consecutive patients presenting with extruded nasal implants from 1986 to 2000. Patients were selected from a large database of revision rhinoplasty cases. Inclusion criteria were: 1) at least one previous rhinoplasty procedure, 2) an extruded nasal implant that was documented preoperatively, 3) immediate reconstruction that was carried out with irradiated homograft costal cartilage (IHCC), and 4) at least 1 year of follow-up recorded, including standard postoperative rhinoplasty photographs. A total of 18 patients met the inclusion criteria and form the basis of this study. Data gathered from the charts included date of surgery, last date of follow-up, location of implant extrusion, alloplastic material, specific use of IHCC for reconstruction, percent of clinical IHCC resorption at last follow-up, and presence of warping of the IHCC. RESULTS: All 18 patients were satisfied with the cosmetic outcomes of their nasal reconstructions. The most common extruded alloplast was Silastic, followed by Gore-Tex (W.L. Gore & Associates, Inc., Flagstaff, AZ). There were no cases of extrusion or infection of the IHCC implant subsequent to immediate reconstruction of the extruded alloplast. Clinical resorption of the IHCC was minimal, with a mean follow-up of 26 months. Only one patient had a complication, warpage, resulting in removal of the IHCC. In that patient, the IHCC still had carving markings on the implant after 2 years in vivo. CONCLUSIONS: In this series of patients, a novel surgical protocol was used. The extruded implant was removed and immediate reconstruction with irradiated rib cartilage was done. All patients were evaluated for postoperative infection, graft extrusion, and satisfaction with cosmetic result. There was one major complication in this series of 18 patients, warping of the IHCC, which necessitated removal and replacement. This approach appears to be a reasonable method for reconstruction of extruded nasal alloplasts.

Unilateral osteotomies for external bony deviation of the nose.

Most crooked noses, at the end of a regular rhinoplasty, seem well positioned in the midline. However, several months later, the nasal pyramid may begin its lateral migration and the original deviation, to the chagrin of the surgeon, is partially reproduced. An approach to the externally deviated bony pyramid is reemphasized, involving the performance of one or more osteotomies on only one side of the nose.During the course of a regular rhinoplasty, the bilateral lateral osteotomies displace the lateral nasal walls medially. However, if only a unilateral osteotomy is performed, the nasal dorsum will seem to deviate toward the opposite side. This paper discusses in further detail how to use unilateral osteotomies in the rhinoplasty of an externally deviated nose. Although the unilateral osteotomy technique is not a new concept, it did not receive so far the interest it deserves among surgeons. The unilateral osteotomy technique is an adjunctive solution to a complex problem.

Endoscopic application in aesthetic and reconstructive facial bone surgery.

Twenty-three cases of endoscopically assisted facial bone surgery were performed over the past 3 years. Our series is consistent with 16 cases of aesthetic contouring surgery and 12 treatments of facial bone fracture, including three cases for recontouring of frontal bone, three cases for recontouring of zygoma, endoscopically assisted correction of three zygomatic and blowout fractures, four cases for rhinoplasty and septoplasty for deviated nose, and three cases for mandible contouring surgery. To accomplish this technique, a rigid 4-mm, 30-degree down-angled endoscope was used. The frontal bone or zygomatic arch was approached endoscopically through two or three small incisions on the frontal or temporoparietal scalp. All endoscopic instruments were then manipulated through these incisions. The approach for endoscopically assisted rhinoplasty is the same as with standard rhinoplasty procedures. The approach for zygoma complex and maxillary sinus needs an intraoral incision. Recontouring of zygoma, mandible, and nasal dorsum by an air-driven burr and rasp was performed with endoscopic visual assistance. A plate and screw fixation for zygomatic arch fracture requires an additional small skin incision over the plate for the trocar method. The duration of follow-up ranged from 6 months to 30 months. The postoperative course was satisfactory with a few complications. The extra time needed for the endoscopic procedures was less than 1 hour. Endoscopically assisted facial bone surgery can be performed with adequate visualization and direct manipulation of all facial bones. Complications usually associated with extensive incisions in the bicoronal approach may be avoided. Poor visualization in the conventional approach for operation of orbit, nose, maxillae, and mandible may be avoided by use of the endoscope. This technique may prove to be ideal for aesthetic surgery for facial skeleton with smaller scar and less morbidity.

The use of alloderm for the correction of nasal contour deformities.

What rhinoplasty surgeon has not been frustrated by unmet expectations from unreliable graft materials? The quest for an ideal graft continues. Septal cartilage is not always adequate in amount or substance. Ear cartilage may cause unsightly irregularities over time. Cranial bone or rib harvest sites add to the complexity of the procedure and can be intimidating for many operators. This article describes the authors' successful experience with AlloDerm onlay grafts for the correction of nasal contour deformities in 58 primary and secondary rhinoplasty cases by means of the open and endonasal approaches. Forty-two patients received an open-approach procedure; the remaining 16 received grafting through an endonasal or closed approach. Thirty-seven of the patients were secondary rhinoplasty patients, and some underwent multiple nasal corrections. The indications, intraoperative surgical technique of graft placement, and representative results will be discussed. Long-term follow-up showed good results, though partial graft resorption occurred in some patients. Overall, this experience with AlloDerm for nasal augmentation was encouraging.

Primary definitive nasal correction in patients presenting for late unilateral cleft lip repair.

Almost 25 percent of unilateral cleft lip and palate patients present with their deformity in their teens or later years in the developing world. Because more than 80 percent of the world population lives in the developing world, the established protocol for repair of these deformities is not applicable to these patients. Despite the magnitude, there are no significant reports in the literature that deal with this problem. Several issues need to be addressed, but the author limits himself here to the correction of the nasal deformity. The patients at this age are very much concerned with the aesthetic outcome. Procedures described hitherto for primary nasal correction in infants are not successful in restoring nasal shape and symmetry at this late age of presentation. Our experience with radical correction of secondary nasal deformity in unilateral cleft lip patients presenting late prompted us to extend the concept by undertaking a definitive primary correction of the nasal deformity in cleft patients presenting late. Twenty-two patients with unilateral cleft lip deformity (nine male patients and 13 female patients) with ages ranging from 13 to 22 years, presenting between August of 1997 and December of 2000, are included in this study. Of these, 11 patients had a cleft of the lip alone, eight also had a cleft of the alveolus, and three had a cleft of the palate continuous with the cleft lip. All patients showed some maxillary hypoplasia. An external rhinoplasty with lip repair was carried out in all patients. The corrective procedures on the nose included columellar lengthening; augmentation along the pyriform margin, nasal floor, and alveolus using bone grafts; submucous resection of the nasal septum; repositioning of lower lateral cartilages; and augmentation of nasal dorsum by bone graft. Clinical follow-up ranged from 4 to 24 months, and the median follow-up period was 13 months. Results have been very good, and much better than results seen earlier with other primary rhinoplasty techniques. While repairing unilateral cleft lip in adolescents, the author thinks it would be most appropriate to address the entire gamut of the deformity in a single stage, provide complete vector reorientation, and augment the hypoplastic elements by autologous tissue. It is not just the fear of poor follow-up, but that merely correcting the lip deformity in these patients without attempting definitive rhinoplasty, in the author's opinion, would be insufficient surgical intervention.

Anatomy of the external nasal nerve.

After rhinoplasty, many patients report numbness of the nasal tip. This is primarily because of injury to the external nasal nerve. It is imperative that surgeons performing rhinoplasty be familiar with the anatomy and the common variations of this nerve. Therefore, the purpose of this study was to present an anatomical study of the external nasal nerve. Twenty external nasal nerves were examined by dissecting 10 fresh cadaver noses within 48 hours of death. On dissection, the exit of the nerve between the nasal bone and upper lateral cartilage was identified. The distance from the point of exit to the midline of the nose and the size of the nerve were measured. The course and the running plane of the nerve were investigated. The nerve branchings were also classified into three types: type I, only one nerve without any branch; type II, one nerve proximally and then splitting into two main branches at the intercartilaginous junction; and type III, two main branches from the point of exit. The point of exit of the external nasal nerve from the distal nasal bone was located 6.5 to 8.5 mm (7.3 +/- 0.6 mm) lateral to the nasal midline. The average diameter of the nerve at the point of exit was 0.35 +/- 0.036 mm. Most of the nerves (95 percent) passed through the deep fatty layer directly under the nasal superficial musculoaponeurotic layer, all the way down to the alar cartilages. In terms of the branching type, type I was observed in 10 of 20 nerves (50 percent), type II was observed in six of 20 (30 percent), and type III was seen in four of 20 (20 percent). On the basis of the results of this study, the following precautions are suggested during a rhinoplasty to minimize the chance of injury to this nerve. First, it is best to avoid deep intercartilaginous or intracartilaginous incisions so that the deep fatty layer is not invaded and the dissection is maintained directly on the surface of the cartilage (deep to the nasal superficial musculoaponeurotic layer). Second, dissection at the junction of the nasal bone and upper lateral cartilage area of one side should be limited to within 6.5 mm from the midline. Lastly, when the nasal dorsum is augmented by an onlay graft, implants or grafts less than 13 mm wide at the rhinion level should be used.

Management of intraoperative fractures of the nasal septal "L-strut": percutaneous Kirschner wire fixation.

BACKGROUND: The area where the septal cartilage joins the perpendicular plate of the ethmoid is a vulnerable region where overresection or disruption during rhinoplasty causes a loss of support and potential collapse of the nasal dorsum, leading to a saddle-nose deformity. Previously described methods of repair involve suture techniques that are often inadequate to restore septal stability. The authors present the senior author's (J. P. G.) experience in managing intraoperative fractures of the septal "L-strut," describe a classification system for the types of dorsal septal L-strut fractures, and present a new method of treatment using percutaneous Kirschner wire fixation. METHODS: The authors conducted a retrospective review of 1372 primary and secondary rhinoplasties performed by the senior author. A classification system was developed to describe the type and location of dorsal septal L-strut fractures. Each patient was treated with immediate restabilization of the fractured dorsal septal L-strut with dorsal spreader grafts, percutaneous Kirschner wire fixation, or a combination of both methods. RESULTS: Seventeen patients sustained an intraoperative fracture of the septal L-strut with an overall incidence of 1.2 percent. Complications included minor dorsal deviation and inadequate reduction/moderate dorsal depression in three patients requiring revision surgery to correct the dorsal deformities. CONCLUSIONS: An intraoperative fracture of the septal L-strut is a rare but unfortunate occurrence during rhinoplasty. Although technically difficult to perform, the percutaneous Kirschner wire fixation technique with or without spreader grafts is a novel and effective approach to this complication.

Improved nasal tip projection in the treatment of bilateral cleft nasal deformity.

The cleft nose deformity in bilateral cleft lip and palate patients with severely flattened alar cartilages, a short, scarred columella, and thickened skin is a reconstructive challenge. The Wolfe double-arch tip rhinoplasty technique was compared with a cartilage release and tip grafting technique to determine the optimal modality for tip projection and columella lengthening. Patients with significant bilateral cleft nasal deformities and previous bilateral cleft lip repairs were divided into two groups (n = 22). Group 1 (double-arch) patients underwent an open rhinoplasty using conchal cartilage grafts to create a columellar strut and new lower lateral arches placed over the existing arches (n = 12). In group 2 (release and tip graft), the lower lateral cartilages were released, and nasal tip grafting was performed (n = 10). Preoperative and 6-month postoperative measurements, including (1) columellar length, (2) alar base-nasal tip-columellar base (ATC) angle, and (3) lateral tip projection, were compared. The lateral tip projection is the perpendicular distance between the nasal tip and a line created from the connection of points at the nasion to the subnasale. In group 1 (double arch), the mean columella length increased 47.2%, whereas in group 2 (release and tip graft), it only increased 14.1%. The ATC angle had a mean decrease or narrowing of 26.7 degrees in group 1, compared with a 12.5 degrees decrease in group 2. Lateral tip projection improvement was greater in group 1 (52.2% increase) compared with group 2 (19.9% increase). The authors' data showed that for the difficult bilateral cleft nasal deformity with significant tip flattening, the double-arch tip rhinoplasty provides improved nasal tip projection.

Butylcyanoacrylate tissue adhesive for columellar incision closure.

Cosmetic outcome of the columellar incision closure in external rhinoplasty patients has been a subject of discussion. This study was conducted to assess whether tissue adhesives provide an alternative option for sutureless closure of columellar skin incisions for cases utilizing open technique rhinoplastic surgery. One hundred and one patients undergoing external rhinoplasty were randomized to either topical application of butylcyanoacrylate or polypropylene sutures for columellar skin closure. The majority of tension on the wound edges was taken up using 5-0 chromic catgut. Cosmetic outcomes were evaluated by two otolaryngologists independently using visual analogue and Hollander wound evaluation scales in a blinded manner. There was no statistically significant difference in cosmesis between the surgeons' evaluation scores for either type or repair of the columellar incision. Since the tissue adhesive forms its own protective barrier, post-operative care is simplified. Closure with adhesives eliminates the need for post-operative suture removal requiring an extra visit that should lead to more efficient use of physician and patient time. Butylcyanoacrylate performs cosmetically as well as standard suture closure of columellar skin incision used for external rhinoplasty.

[Surgical approach to the nasal valve stenosis].

Nasal valve, originally defined by Mink (1903), has changed its concept and is now regarded as slit-like opening between the caudal end of the upper lateral cartilage and the septum. Contrary to Caucasians whose smallest area of the nose lies at the nasal valve, the narrowest part of Japanese nose situates at the area between the anterior portion of the inferior turbinate and the septum. Thus, we have fewer chance to experience patients with stenotic nasal valve. Six patients complaining nasal obstruction resulted from nasal valve stenosis, mainly due to dislocated or collapsed upper lateral cartilage, underwent surgery during the last 2 years and a half. Cases of septal deformity, even it it produced valve stenosis, were excluded in this study. Surgical intervention was directed toward reconstruction of normal anatomic relationships, usually by widening the nasal valve angle and preventing collapsibility. Three underwent open rhinoplasty with gull-wing columellar skin incision, whereas 3 others were operated on via transnostril approach. History of midfacial trauma caused us to choose open rhinoplasty for restoring the function and structure. Immediate postoperative result was excellent in the aspect of appearance and subjective data regardless of surgical approach. Open rhinoplasty provided a splendid long-term result without remarkable complications. On the other hand, 2 cases operated via transnostril approach complained recurrence of stuffy nose.
