Extrinsic eyelid ectropion

Extrinsic ectropion is caused by loss of skin around the orbital margins. Every patient with cicatricial ectropion should be assessed thoroughly to determine if the cause is intrinsic, extrinsic, or both. This assessment is extremely important when dealing with severe deformities after burns, cancer, or noma, for example. The assessment allows a proper planning of surgery. As a rule, the original size and location of the missing tissues should be recreated and the defect replaced by homologous tissues.
