Abstract

Paralytic lagophthalmos and ectropion in the treatment of leprosy patients are serious complications of facial paralysis, which may lead to exposure keratitis and corneal ulceration, which can further lead to blindness. In 1995, 1997, 1999 and 2001, we reported in this journal on the surgical treatment of paralytic lagophthalmos and ectropion. In the 1st report, made in 1995, for lid closing, I (Ahn) performed various methods of traditional surgery such as temporal muscle transfer, medial and lateral canthoplasty, as well as gold implantation. In the 2nd report, made in 1997, we (Ahn and Park) presented a combination treatment of gold plate with minor changes of design and weight in the upper lid and medial canthoplasty with horizontal shortening in the lower lid. In the 3rd report, made in 1999, we described an additional graft of conchal cartilage in the lower lid. However, the lateral end of the cartilage would warp and create new partial ectropion several months later. Therefore, we shifted from cartilage to Alloderm(R), acellular dermal graft. In the 4th report, made in 2001, we reported that Alloderm(R) is a good substitute for the cartilage and is also an effective volume filler to the atrophic lower lid. The medial portion of the lower lid often presented with a recurrence of the ectropion, despite having tightened the bilateral plication of the medial and lateral canthal ligaments with an Alloderm(R) graft in the inferior border of the tarsus. In order to treat the recurring ectropion, a modified permanent tarsorrhaphy was performed. We have noted that a modified permanent tarsorrhaphy on the medial canthal area in Z-plasty successfully corrected the partial ectropion and resulted in decreased epiphora and increased esthetic satisfaction.
