Oncologic surgery of the eyelid and orbital region.

Oncologic surgery of the eyelid and orbital region is a challenge in dermatologic surgery. This region presents difficulties and possible complications that do not exist at other sites, including ectropion, epiphora, corneal exposure, keratitis, conjunctivitis, and lagophthalmos. Adequate oncologic surgery associated with the best possible functional and cosmetic result requires extensive knowledge of the anatomy, innervation, and blood supply of the eyelid and anatomy of the lacrimal apparatus. We present examples of reconstructive surgical techniques that can be used after the excision of tumors of the upper or lower eyelid, with descriptions of the different flaps and grafts employed in our department in recent years. We also review the surgical techniques according to the site and size of the lesions.
