Suture tip plasty.

The three main characteristics of the nasal tip are projection, rotation, and contour. During rhinoplasty the surgeon will strive to preserve or change these characteristics in a predictable fashion, avoiding undesirable sequelae, even after long-term follow-up. Conservation, relocation and augmentation rather than reduction are key principles in modern rhinoplasty, i.e. for obtaining gratifying tip surgery. Interdomal suture, transdomal suture, and lateral crural steal follow these modern principles, while having their clear indications for different nasal tip pathology. All three types of techniques involve (semi-)permanent sutures to change the shape of alar cartilages and can be considered complementary. Based on the same surgical philosophy these three techniques can be captured with the term "suture tip plasty". The objective of this paper is to describe, in a retrospective fashion, a series of 112 patients in whom suture tip plasty has been used as part of the rhinoplasty procedure. The technique proved versatile with predictable results and few manageable complications.

[Correction of the external ear using cartilage-sparing techniques].

OBJECTIVE: To establish the value of cartilage sparing suture techniques for correction of prominent ears. DESIGN: Retrospective study. LOCATION: Gooi-Noord Hospital, Blaricum, the Netherlands. METHOD: Between 1989 and 1992, 117 ears in 62 patients were corrected for prominence. Results were evaluated using the McDowell criteria for anatomy and localisation of the ear. RESULTS: Of 117 ears 108 were corrected successfully. A recurrence was seen in 6 ears and 3 ears showed overcorrection. Reoperation was needed in 2 ears. A suture was extruded in 15 ears, which could be treated relatively easily in 14. CONCLUSION: Cartilage sparing suture techniques for correction of the specific anatomic deformities of prominent ears prove to be successful. Suture extrusion was the most frequent, but minor, complication. Suture extrusion appears to be dependent upon suture material and localisation.

Open septorhinoplasty. Experiences in 200 patients.

There are two approaches for septorhinoplasty, the endonasal approach and the external approach. The external approach is much criticized for the risk of columellar skin flap necrosis and visible scar formation. This series of patients has shown that the risk can be minimized using a mid-columellar broken incision with a meticulous closure technique. The exposure of the surgical anatomy is much better than with the endonasal approach, leading to better insight in nasal deformities and more detailed reconstruction. There seems to be no reasonable objection which can be raised against the columellar incision to reject the open approach.

Nasal dorsal cyst after rhinoplasty.

Nasal dorsal cyst formation after rhinoplasty is considered a rare complication. These cysts are due to entrapment of mucosal remnants in the subcutaneous space. Meticulous surgical technique aimed at preserving the mucosal lining may prevent cyst formation. Surgical excision with the open approach is a reliable treatment. A case of nasal dorsal cyst after previous rhinoplasty is presented. After four years no sign of recurrence is noted.

[Open septum rhinoplasty; results in 80 patients].

Corrective rhinoplasty may be performed in two ways. With the traditional endonasal approach the incisions are made on the inside of the nose. The open technique uses an incision made on the outside of the nose, in the columella. This affords better insight into the surgical anatomy than the endonasal approach. It is concluded from the literature and from experiences in 80 patients that the advantages of the open technique more than compensate for the (avoidable) risks such as impaired wound healing and an ugly scar.

The inferior turbinate flap for closure of septal perforations.

In 31 patients a symptomatic septal perforation was repaired using an inferior-turbinate flap originally described by Masing. In approximately 50% of the cases the perforation was closed for two-thirds or more. Postoperative scarring causing nasal obstruction or alar asymmetry occurred in 21% of the cases. Some specific symptoms such as epistaxis, whistling and frontal headache appeared to improve even after partial closure. However, the overall degree of satisfaction of the patients and the degree of closure of the perforation were related. Based on the results of this series the inferior-turbinate flap did not prove satisfactory for the closure of septal perforations.

Acoustic and aerodynamic parameters of speech after laryngectomy and the Staffieri procedure.

The voice obtained with the Staffieri method of surgical voice rehabilitation after total laryngectomy was studied in 20 subjects and objectively described in terms of selected acoustic and aerodynamic parameters. Intensity and frequency, pressure and airflow were studied during sustained phonation of the vowel 'a'. Simultaneous recordings showed a relationship between intensity and between fundamental frequency, pressure and airflow in most of the subjects. As the subjects in the present study were not able to produce a vowel at target intensities and frequencies, the data were interpolated to 65 dB (A) intensity level for comparison purposes. We found no indication that from an acoustical and aerodynamical point of view, the Staffieri procedure should be preferred over other alaryngeal voice production methods.

The role of the upper oesophageal sphincter in voice rehabilitation after laryngectomy and Staffieri's procedure.

The Staffieri method was used for voice rehabilitation after total laryngectomy in our patients. Leakage of saliva has been a problem in some. It has been suggested that aspiration could be due to specific pressure relations in the pharynx, upper oesophageal sphincter and cervical oesophagus during deglutition (Mann et al., 1980). Regarding voice production, the upper oesophageal sphincter is probably the main sound source, functioning in essentially the same way as in oesophageal speech. Intraluminal pressure recordings at rest and during swallowing were used in 16 Staffieri speakers and 9 oesophageal speakers. Upper oesophageal sphincter dysfunction was seen more often in Staffieri speakers with aspiration problems than in Staffieri speakers without aspiration problems, but the relation is not clearly understood. A definite relation could be established between upper oesophageal sphincter function in terms of relaxation and coordination and aerodynamic pressure measured in the tracheostoma, necessary to sustain phonation. After dilatation of the oesophagus, produced by the inflow of air, a reflex rise in the upper oesophageal sphincter pressure is thought to occur. The pressure necessary to sustain phonation probably depends on the extent to which this reflex mechanism occurs and on the ability of the patient to induce a relaxation of the upper oesophageal sphincter before air expulsion. Selective myotomy will possibly lower the necessary pressure and enhance vocal rehabilitation. Whether this will solve a part of the aspiration problems in Staffieri speakers is completely unpredictable, as the relation of the motor function of the upper oesophageal sphincter and the aspiration problems is not well understood.

Granular cell tumor of the proximal esophagus. A rare disease.

In 1926, Abrikossoff described a tumor, usually benign, which only rarely appears in the esophagus. In a 40-year-old woman, the authors found a multicentric granular cell tumor which was localized in the cervical esophagus and in the subcutaneous tissues over the right scapula; it was removed surgically. Granular cell tumors causing stenosis of the upper esophagus have been described only four times in the literature. Characteristics and treatment are discussed.
