No-scar Asian epicanthoplasty: a subcutaneous approach.

PURPOSE: The epicanthal fold is a normal finding in the medial portion of the upper eyelid in many Asians. We describe a simple technique of removing the excess muscle and softening or eliminating the epicanthal fold without making incisions in the medial canthal region, thus avoiding complications such as scarring or web formation METHODS: Interventional case series. The subcutaneous epicanthoplasty was performed on all Asian patients undergoing concurrent upper eyelid blepharoplasty or aponeurotic ptosis repair. RESULTS: Thirty-eight Asian patients underwent epicanthal fold correction between January 1996 and December 2000. All patients had softening of the epicanthal fold; however, some cases of mild undercorrection were noted. CONCLUSIONS: Softening or elimination of the Asian epicanthal fold can be accomplished without making skin incisions in the medial canthal region. Our technique is a simple, graded procedure that can be performed in conjunction with upper blepharoplasty or ptosis repair.

The quasi-integrated porous polyethylene orbital implant.

PURPOSE: To describe a new quasi-integrated porous polyethylene orbital implant that combines the advantages of host tissue incorporation and improved motility with a single-stage surgery. METHODS: Twenty-four consecutive patients undergoing primary or secondary orbital implantation received the quasi-integrated porous polyethylene implant. Approximately 6 weeks after implantation, a custom-fitted prosthesis was made by an impression technique to provide a "lock-and-key" fit with the orbital implant. Postoperative complications and motility of the prosthetic shell were evaluated. RESULTS: During the 27-month period between December 1998 and March 2001, 24 patients received the quasi-integrated porous polyethylene implant as a buried orbital implant. Thirteen patients received the implant as a primary orbital implant after either evisceration or enucleation and 11 patients received the implant as a secondary orbital implant. Follow-up ranged from 3 months to 30 months, with an average of 16.9 months. All patients were considered to have good motility of their prosthetic shell at their final follow-up visit. No cases of implant extrusion or migration were noted. Two patients required deepening of their inferior fornix to accommodate the increased motility of their prosthesis. CONCLUSIONS: The new quasi-integrated porous polyethylene orbital implant provides improved motility without the need for secondary placement of pegs or screws. It has the advantage of biocompatibility, allowing host tissue incorporation to resist implant migration and extrusion. The implant is available in three sizes: small, medium, and large, approximating the volume of a 16-, 18-, and 20-millimeter sphere, respectively.

Alternating ptosis associated with intermittent exotropia.

A unique case of alternating, poorly controlled, intermittent strabismus that improved after repair of bilateral, alternating congenital ptosis is described. A 7-year-old boy with bilateral, alternating congenital ptosis and poorly controlled, intermittent exotropia underwent bilateral frontalis suspensions. After surgery, the patient demonstrated improved control of his exotropia. We conclude that an alternating ptosis may lead to sensory deprivation of the occluded eye and decreased fusion, causing an intermittent strabismus to be poorly controlled. Repair of the ptosis to a sufficient eyelid height bilaterally may improve control of the strabismus, obviating strabismus surgery.

Internal brow elevation at blepharoplasty.

OBJECTIVE: To present data on a transblepharoplasty technique that provides a safe and reliable brow elevation and glabellar furrow reduction by releasing inferior tethering and weakening the brow depressor muscles. DESIGN: Nonrandomized retrospective case series and surgical technique description. RESULTS: One thousand patients who underwent internal brow elevation for cosmesis associated with upper blepharoplasty over the past 9 years were reviewed. Follow-up ranged from 6 months to 9 years. There were no serious long-term complications. All patients experienced forehead hypesthesia, which was temporary in most patients. Only 2 patients complained of prolonged and bothersome forehead hypesthesia lasting longer than 2 years. CONCLUSION: The internal brow elevation at blepharoplasty is a reproducibly safe and effective technique to improve eyebrow appearance without fixation.

Correction of congenital blepharoptosis in oculomotor-abducens synkinesis.

A 4-year-old boy was referred for blepharoptosis. Examination revealed the presence of oculomotor-abducens synkinesis (right upper eyelid elevation with right gaze). Reports of congenital oculomotor-abducens synkinesis syndromes are rare. Two surgeries required more levator resection than anticipated to obtain the first, to our knowledge, reported successful result in this condition.

Congenitally enlarged extraocular muscles: can congenital thyroid eye disease exist in a euthyroid infant?

A 2-month-old boy presented with hypotropia, eyelid retraction, and proptosis of the left eye. CT and ultrasound demonstrated enlarged extraocular muscles. Both the infant and mother were euthyroid. The patient underwent inferior rectus recession, lower eyelid retractor disinsertion, and entropion repair. Biopsy of the inferior rectus and oblique muscles was normal. The clinical presentation and workup appear to be most consistent with thyroid eye disease, which, to our knowledge, would be the first reported case of euthyroid congenital thyroid eye disease with a euthyroid mother.
