Techniques in eyelid wound closure.

While one of the most basic techniques in eyelid surgery is the repair of an eyelid defect that involves the margin, many eyelid defects are still poorly repaired; and much confusion still exists in this area. Based upon sound anatomic and surgical principles, we suggest several modifications of classically described techniques: (1) The greyline suture is replaced by a tarsal suture through the meibomian gland orifices to provide a stronger closure and better alignment. (2) All tension of closure is supported by the deep tarsal sutures rather than by the margin sutures to avoid notch formation or unsightly scars. (3) A two-layered closure where orbicularis and tarsus is closed in a single layer is technically easier and gives results comparable to the classically taught three-layered closure. Conjunctival sutures in the tarsal portion of the eyelid are unnecessary and frequently cause corneal irritation. (4) When lid resection is performed, a pentagonal excision rather than a "V" or wedge resection should be used to minimize tension on the margin when closed. We present in an illustrated step-by-step fashion our preferred technique which gives consistently good results.
