Treatment of enophthalmic narrow palpebral fissure after blow-out fracture.

Surgery for a narrow palpebral fissure caused by enophthalmos after a blow-out orbital fracture was performed in three patients from seven months to three years after injury. The surgery was directed not to the cause of the enophthalmos, but to the narrowed palpebral fissure which was the noticeable cosmetic defect. The surgical procedure used to widen the palpebral fissure was the Müller's muscle-conjunctival resection blepharoptosis operation, and a phenylephrine test was used preoperatively to select candidates for this operation. After widening of the palpebral fissure, which created the illusion of exophthalmos, the cosmetic result was acceptable.
