The significance of orbital anatomy and periocular wrinkling when performing laser skin resurfacing.

Knowledge of orbital anatomy and the interaction of muscle contractions, gravitational forces and photoagingis fundamental in understanding the limitations of carbon dioxide (CO2) laser skin resurfacing when rejuvenating the skin of the periocular area. Laser resurfacing does not change the mimetic behavior of the facial muscles nor does it influence gravitational forces. When resurfacing periocular tissue, the creation of scleral show and ectropion are a potential consequence when there is an over zealous attempt at improving the sagging malar fat pad and eyelid laxity by performing an excess amount of laser passes at the lateral portion of the lower eyelid. This results in an inadvertent widening of the palpebral fissure due to the lateral pull of the Orbicularis oculi. Retrospectively, 85 patients were studied, who had undergone periorbital resurfacing with a CO2 laser using anew treatment approach. The Sharplan 40C CO2 Feather Touchlaser was programmed with a circular scanning pattern and used just for the shoulders of the wrinkles. A final laser pass was performed with the same program over the entire lower eyelid skin surface, excluding the outer lateral portion (e.g. a truncated triangle-like area),corresponding to the lateral canthus. Only a single laser pass was delivered to the lateral canthal triangle to avoid widening the lateral opening of the eyelid, which might lead to the potential complications of scleral show and ectropion. When the area of the crows' feet is to be treated, three passes on the skin of this entire lateral orbital surface are completed by moving laterally and upward toward the hairline. Patients examined on days 1, 7, 15, 30, 60, and one year after laser resurfacing showed good results. At two months after treatment, the clinical improvement was rated by the patient and physician as being "very good" in 81 of the 85 patients reviewed. These patients underwent laser resurfacing without complications. The proposed technique of periocular resurfacing prevents complications of scleral show and laxity in the lateral eyelid opening and even ectropion, because treatment conforms to the osseo-muscular anatomical relationship of eyelid structures.

Septal-myocutaneous flap technique for lower lid blepharoplasty.

Lower lid blepharoplasty can present a significant challenge to the facial plastic surgeon. Routine findings of periorbital fat herniation and dermatochalasia of the lower lid are often associated with the presence of more occult findings, e.g., tarsoligamentous laxity and ectropion. Traditional surgical approaches to the aging lower eyelid utilize the skin flap, the skin-muscle flap, and the transconjunctival technique. The limitation of any one of these procedures alone is that of not addressing the multiple problems of the aging eyelid; this may lead to common postoperative problems of lower lid blepharoplasty, including lid retraction, lagopthalmos, scleral show, rounding of the lateral canthus, and ectropion. We present an integrated surgical solution to the functional and anatomical defects of both the anterior and posterior lamellae, and, when indicated, lateral canthal support. The procedure incorporates a small lateral subciliary and lateral canthal incision with a myocutaneous advancement flap developed in a plane deep to the orbital septum, combined with transconjunctival blepharoplasty for removal of herniated orbital fat. It allows for simultaneous management of the multiple defects of the aging lower eyelid and complete restoration of the relevant anatomy, while avoiding the common pitfalls of lower lid blepharoplasty. We present our experience of 64 patients who underwent bilateral combined septal-myocutaneous advancement flap and transconjunctival blepharoplasty. Indications and postoperative results are reviewed. No complications, including scleral show or ectropion, have been noted over the 4-year postoperative period.

Porous polyethylene implants in orbital floor reconstruction.

The purpose of this article is to present the authors' experience with the use of porous polyethylene ultrathin sheets for orbital floor reconstruction. Thirty-two patients with orbital floor fractures were treated with porous polyethylene ultrathin sheets. Sixteen cases corresponded to orbitozygomatic fractures, 11 cases corresponded to pure orbital floor fractures, and five corresponded to panfacial fractures. The subciliary approach was used in 15 patients and the transconjunctival approach in nine; another three patients were operated on through a preexisting eyebrow wound, two were operated on with a subtarsal approach, two were operated on through an eyebrow extension of a facial wound, and one patient was operated on through the facial wound. Intraoperatively, all patients received a prophylactic dose of intravenous antibiotics. Postoperatively, 24 patients received amoxicillin clavulanate for 5 to 7 days, two patients received clindamycin, and six patients received no antibiotics. Enophthalmos was corrected in 15 of 24 patients (62.5 percent), and hypoglobus in nine of 11 (82 percent). Diplopia was resolved in 25 of 28 patients (89.3 percent) with preoperative impairment. Extrinsic eye movement impairment was resolved in 25 of 27 patients (92.6 percent). A preoperative visual acuity deficit was present in four patients (12.5 percent) and was resolved in one (from 20/100 to 20/20). Visual acuity improved in one patient (from 20/60 to 20/30). In the other two patients, visual acuity remained altered (from 20/30 to 20/30). One patient (3.1 percent) suffered blindness induced by surgery. Nine of 26 patients (34.6 percent) had residual infraorbital nerve hypesthesia and five (19.2 percent) had residual paresthesias. Postoperatively, epiphora was present in six patients (18.8 percent) and ectropion in five (15.6 percent). Although there was no statistical significance between the surgical approach and the presence of epiphora (p = 0.211) and ectropion (p = 0.422), patients who were treated using the transconjunctival approach suffered reduced ectropion (0 percent) compared with patients treated using the subciliary approach (20 percent). However, patients treated using the transconjunctival approach suffered increased epiphora (22.2 percent) compared with those treated with the subciliary approach (13.3 percent). There were four cases (12.5 percent) of postoperative facial infections. Two of these cases were resolved with systemic antibiotics, one was resolved with bone sequestrum resection, and one patient needed removal of the implant. Orbital infections were related in all cases to titanium osteosynthesis miniplates or skull bone graft. When comparing patients who were treated with and without antibiotics, no statistical differences (p = 0.958) were found relative to the presence of infections. Correction of hypoglobus is technically easier than enophthalmos, because enophthalmic correction requires a wide, deep subperiosteal dissection and implant positioning, posterior to the equator of the globe, with the inherent risk of orbital apex injury.

Periorbital reconstruction with adjacent-tissue skin grafts.

BACKGROUND: Reconstruction in the periorbital area is challenging owing to the complex function of the eye, relative lack of adjacent loose tissue, free anatomic margin, central facial location, and the need to maintain symmetry with the contralateral eye. Reconstructive options risk crossing anatomic margins, deviation of the lid margin (ectropion), persistent lymphedema, and repair with skin of dissimilar color, texture, and thickness. OBJECTIVE: The purpose was to describe a reconstructive option that would avoid crossing cosmetic units or subunits, minimize the risk of ectropion, repair with tissue of similar surface characteristics, and maintain function and symmetry with the contralateral side. METHODS: The adjacent-tissue skin graft provides closure in cosmetic units and subunits, avoids tension on the lid margin, and provides similar skin for repair. The procedure is demonstrated by graphic and photographic examples. RESULTS: The procedure provides for esthetic repair of the periorbital area and minimizes the risk of ectropion, lymphedema, asymmetry, and dysfunction of the lids and lacrimal system. CONCLUSION: Adjacent-tissue skin grafts are a useful alternative for reconstruction of partial-thickness defects on the eyelid and periorbital area.

[Plastic surgery of the anorectal area. Indications, technique and outcome].

Anal canal stenosis with alteration of the sensoric continence or mucosal ectropion may occur after anorectal operations. Island flaps with perianal skin or the VY-anoplasty are simple plastic methods to reconstruct the anorectal region and cure patients--who often have suffered for a long time--from anal strictures or mucosal ectropion. In the period from 1994-1998 we reconstructed the anodermal region of seven patients using one of the above mentioned anorectal plastic procedures. Three patients complained of an anal stenosis and one patient suffered from an ectropion of the rectal mucosa after an improperly performed Whitehead hemorrhoidectomy. Three patients had a sensomotoric incontinence twice due to a congenital anal atresia and in one case caused by an accident. All patients were highly pleased after the operation--no complication occurred.

Use of the carbon dioxide laser for removal of lesions adjacent to the punctum.

Neoplasms, small or large, adjacent to the punctum can create a dilemma as to their removal and its repair. Punctal stenosis, total closure, and punctal ectropion are complications that can occur after surgery. Punctal complications can cause epiphora with secondary chronic blepharoconjunctivitis and skin excoriation due to chronic rubbing or wiping off of tears by the patient. This report will discuss carbon dioxide laser excision of neoplasms adjacent to the punctum. This laser approach provides a bloodless field, minimal postoperative pain, and good postoperative appearance without scar formation. Smaller adjacent lesions cause no punctal abnormality. Larger lesions adjacent to the punctum which have already caused ectropion did not worsen the ectropion postoperatively.

The medial tarsal strip.

Medial canthal malpositions and marked medial ectropion due to laxity, scarring, or trauma can be difficult to correct. Medial canthal tendon publications have been advocated but they do not achieve adequate posterior and medial placement of the medial canthal angle and they lack permanence. One of us (R.L.A.) has developed a surgical technique for correcting these problems that is a modification of the lateral tarsal strip procedure used to correct lateral canthal tendon laxity and malposition. The medial tarsal strip procedure repositions and tightens the medial lower or upper eyelid, establishing a normal anatomic appearance. Its use is indicated in cases of medial canthal malposition or marked medial ectropion associated with a nonfunctioning canalicular system or in those cases in which loss of function of a patent canaliculus is acceptable or desirable. The advantages of the medial tarsal strip are as follows: (1) surgery is directed at the site of the defect; (2) recurrence of canthal tendon laxity and elongation is avoided; (3) a more medial and posterior positioning of the medial eyelid can be obtained; (4) any amount of eyelid laxity can be corrected simultaneously; (5) the almond-shaped canthal angle is preserved or reestablished; and (6) the procedure is fast and easily performed.

[Fornix reconstruction in ocular pemphigoid with Goretex surgical membrane].

UNLABELLED: After separation of symblepharons in ocular pemphigoid, transplantation of nasal or bucal mucosa is recommended to prevent recurrent lid fusion; however, it is not always successful. BACKGROUND: An 86-year-old patient was referred to our eye clinic because of trichiasis in ocular pemphigoid. In the right eye, the only functional eye, fusion of the lower lid and the globe was present. There was severe trichiasis with multiple lesions of the cornea and beginning neovascularization. The left eye showed complete fusion of the lid fissure and neovascularization of the cornea. To prevent the right eye from suffering the fate of the left, we tried to find a simple surgical method that could easily be performed on the multimorbid patient. METHOD: Under parabulbar anesthesia we separated the lower lid from the globe until free passive motility of the lower lid was achieved. A cut-to-size piece of Gore-Tex surgical membrane was prepared and fixated with resorbable u-sutures on the inner lid. The membrane was left in place for 4 weeks until suture lysis. A silicone tube, which was transitorily fixed to the outer lower lid, had an additional ectropionizing effect. Three months later, lower-lid ectropion surgery was performed, combined with tarsectomy to obtain a long-term effect. RESULT: Six months later the lower-lid fornix had stabilized, and the lid and globe had good motility. The corneal lesions had healed. CONCLUSION: The use of 0.1 mm membrane prevents penetration of cell because of the microstructure. Similar to the "bare sclera" technique, which is used in selected cases in strabismus or pterygium surgery, the inner lid and sclera were epithelialized separately from the remaining conjunctiva. The surgical membrane prevented recurrence of the symblepharon. We think the presented technique is an easy, quick method of preventing recurrence of lid fusion after separation of symblepharons.

Ocular complications of Tangier disease.

Tangier disease, or familial high-density lipoprotein deficiency, is an inherited disorder resulting in tissue deposition of excessive cholesterol esters. Although associated corneal clouding has been reported to produce little visual impairment, this patient with Tangier disease had corneal clouding, decreased corneal sensation, and cicatricial ectropion and experienced slowly progressive marked visual impairment. All ocular cases of Tangier disease are reviewed. Ectropion and incomplete eyelid closure may precede corneal clouding and should be recognized as signs associated with Tangier disease. The combination of exposure keratopathy and corneal infiltration can cause significant visual impairment.

A cheek island flap for the lower eyelid.

An island transposition flap for use in lower eyelid reconstruction and the treatment of ectropion is described. The flap is based on a subcutaneous pedicle 1 to 2 cm lateral to the outer canthus. Its long axis extends inferolaterally from this point, and the donor site can be closed directly. The skin of the full width of the lid can be replaced, and where skin replacement is not required the flap may be de-epithelialised and used to provide bulk and support only. The flap has also been successfully lined with a nasal muco-chondral graft. Clinical examples are described, including the treatment of cicatricial, senile and paralytic ectropion, and the repair of defects ranging from skin alone to the full thickness of the lid.

Eye involvement in inherited epidermolysis bullosa: experience of the National Epidermolysis Bullosa Registry.

PURPOSE: To determine the frequency of ocular manifestations in inherited epidermolysis bullosa (EB) within the continental United States and to define the estimated cumulative risks of developing nonscarring (blisters or erosions) and scarring corneal manifestations within each major EB subtype over time. DESIGN: Observational (cross-sectional and longitudinal). METHODS: Up to 16 years of longitudinal follow-up was conducted on 3,280 consecutively enrolled patients in the National EB Registry, an epidemiologic study funded by the National Institutes of Health. Data were stratified by major EB type and subtype. Frequencies of occurrence were determined for eight variables (corneal erosions or blistering; corneal scarring; symblepharons; blepharitis; ectropions; lacrimal duct obstruction; impaired vision; blindness) by contingency tables, and cumulative risks were generated by life table analysis technique. RESULTS: The most common ocular manifestations were corneal erosions and blisters. Frequencies mirrored relative severity of skin disease, with 74.10% of all patients with recessive dystrophic EB, Hallopeau-Siemens (RDEB-HS) and 47.50% of all patients with junctional EB, Herlitz (JEB-H) experiencing at least one episode. Lower frequencies were noted for corneal scarring. Symblepharons and ectropions were most commonly seen in inversa RDEB and JEB-H, respectively. Blindness was reported in 6.47% of RDEB-HS patients. The cumulative risks of nonscarring and scarring corneal lesions in JEB-H at age 5 are 83.18% and 27.08% and at age 25 are 83.18% and 72.22%. With time, the cumulative risk of each in RDEB-HS approached that reported in JEB-H patients. CONCLUSION: Ocular disease activity, particularly corneal, is common in some EB subtypes. Careful ophthalmologic examination should become an integral part of the management of all patients with inherited EB.

The use of a polyglactin suture in the lateral tarsal strip procedure.

PURPOSE: To evaluate the rate of recurrence of horizontal laxity or lid malposition and suture-related complications associated with the use of an absorbable suture in the lateral tarsal strip procedure. DESIGN: Prospective, interventional, consecutive case series. METHODS: A prospective study. SETTING: Institutional. PATIENT POPULATION: One hundred patients with horizontal lid laxity associated with ectropion or entropion. Patients with paralytic ectropion or ocular prostheses were excluded. INTERVENTION: One hundred and five lateral tarsal strip procedures were performed using a 6-0 polyglactin suture. These were combined with full-thickness skin grafts (34), internal (55) or external (23) retractor plications, and inverting sutures (4) as required to correct the lid malposition. MAIN OUTCOME MEASURES: Recurrence of horizontal laxity or lid malposition and suture related complications were the main outcome measures. Suture related wound infection was diagnosed clinically by the presence of pus associated with wound breakdown. RESULTS: One patient failed to reach 3-month follow-up and was excluded. There was one recurrence of horizontal laxity after a mean follow-up period of 9.1 months. Four patients developed lateral canthal wound infections, compared with none at the other operative sites. The 95% confidence intervals for infections in the tarsal strip procedure were 1.1% to 9.6%, which were significantly greater than zero (P < .0001), the infection rate for the other procedures. CONCLUSION: A 6-0 absorbable suture may be used for the lateral tarsal strip and does not lead to a recurrence of horizontal laxity. It does not appear to reduce the wound infection rate associated with this procedure.

Floppy eyelid syndrome in a child with chronic unilateral conjunctivitis.

PURPOSE: To report a 2-year-old child who had chronic unilateral conjunctivitis and spontaneous left upper eyelid eversion during sleep consistent with the floppy eyelid syndrome. METHODS: The patient's parents used a video camera to document nocturnal ectropion of the left upper eyelid. Examination demonstrated left upper eyelid swelling and left palpebral conjunctival hyperemia with papillary hypertrophy. RESULTS: All signs and symptoms of the floppy eyelid syndrome resolved with taping of the left upper and lower eyelids to close the palpebral fissure and to prevent ectropion during sleep, and with application of ocular lubricants. CONCLUSIONS: Floppy eyelid syndrome may manifest in childhood without other contributing conditions and should be considered in the differential diagnosis of chronic papillary conjunctivitis in patients at any age.

The free 'V': a bipennate free flap for double eyelid resurfacing based on the second dorsal metacarpal artery.

We present a patient who had a basal cell carcinoma of the left upper eyelid and ectropion of the left lower eyelid. The patient underwent resection of the tumour and release of the ectropion resulting in a full thickness defect of the skin of his left upper and lower eyelids. The eyelids were reconstructed with a second dorsal metacarpal artery free flap from the left hand. For safety, a dorsal vein of the flap was arterialised and one of the valves of the vein had a valvotomy. The flap survived completely.

Minimally invasive lower eyelid blepharoplasty.

BACKGROUND: Transconjunctival lower eyelid blepharoplasty can significantly reduce the incidence of postoperative eyelid retraction and ectropion encountered with the traditional transcutaneous approach. These complications rarely are encountered because no scarring is induced at the level of the orbital septum and post-orbicularis facia. METHODS: A modification of the transconjunctival blepharoplasty procedure is described in which two small buttonhole incisions are used for fat removal. This procedure was performed in 148 eyelids. RESULTS: All patients had a subjective improvement of eyelid puffiness after the procedure. Lower eyelid retraction or ectropion did not develop in any of the patients. Two patients were concerned with residual eyelid puffiness and redundant eyelid skin. CONCLUSION: The primary advantages of the minimally invasive transconjunctival blepharoplasty are the ease in performing the procedure and the reduction of disruption of the conjunctival surface.

Total reconstruction of a partial-thickness upper eyelid defect with the expanded forehead flap.

This paper demonstrates examples of successful reconstruction of partial-thickness eyelid defects using the expanded forehead flap. Two patients are presented: one in whom cicatrical ectropion was present and the other in whom there was an absence of ectropion. In both patients primary grafting was executed just after the injury was sustained. By the time the patients were referred for reconstruction, mismatch in the quality of the skin and scars along the border of the graft left the area of primary repair to be impaired aesthetically as well as functionally. Reconstruction of the upper eyelid using the expanded forehead flap resulted in excellent approximation of the native tissue. Aesthetic as well as functional capacities were considered in this approximation. The advantage of this technique is that it offers a larger amount of tissue without compromising the aesthetic or functional similarity to the native eyelid.

Stabilization of the posterior limb of the medial canthal tendon using biodegradable tag anchors: a cadaveric model.

PURPOSE: This study describes and tests in a cadaveric model a new method of fixation designed for potential stabilization of the posterior limb of the medial canthal tendon, using biodegradable Tag anchors. METHODS: Study of the possibility of performing surgery to repair medial ectropion using biodegradable polyglyconate Tag anchors was commenced in the sheep cadaveric head model, and in the whole dry human skull model. This was then performed using five preserved human cadaveric whole heads, and pullout tensions were estimated in four of these. Computed tomography and magnetic resonance imaging were obtained for this model in the fifth head, and computed tomography was performed on the whole dry human skull. Dissections were carried out to establish the site of the bony defect in each of the heads. RESULTS: It was possible to obtain good Tag anchor fixation in bone overlying the maxillary and ethmoidal sinuses of the sheep, and in a young human skull. It was also possible to place adequately the anchor in the medial wall of the orbit close to the posterior lacrimal crest in all cases in the human cadaveric model. Pullout strengths were evaluated and found to range from 3.5 N to 12.4 N (mean, 7.5 N). Computed tomography and magnetic resonance imaging failed to demonstrate the biodegradable anchors in both the dry human whole skull and in the fifth cadaveric head, but did demonstrate the bony defects in the medial orbital walls through which the anchor passed. CONCLUSIONS: We have shown, for the first time, the stability of biodegradable Tag anchor fixation in a human cadaveric head model using pullout tensions and dissection studies. This method would allow adequate strength and stability to provide for control of fixation of the medial end of the lower eyelid in patients with medial ectropion and medial canthal tendon laxity.
