Abstract:
Giant dermoid cysts of the orbit are developmental abnormalities that are usually found near the lacrimal gland in adults. The diagnosis of giant dermoid cysts can usually be established by radiographic studies and computed tomographic scanning. A surgical technique for the removal of these lesions with minimal complications is described in detail. Two cases are presented to demonstrate the methods used to diagnose and completely remove giant dermoid cysts with recovery of visual function and extraocular movements.
