A new surgical "noose" technique for excision of pediatric ocular adnexal and anterior orbital cysts.

Abstract

We describe a "noose technique" that facilitates complete surgical excision of all forms of pediatric adnexal and anterior orbital extraocular cysts, including conjunctival retention cysts, parasitic cysts involving the conjunctiva, Tenon's capsule, or rectus muscle, superficial cysts, and deep dermoid cysts. The technique provides good exposure and facilitates handling of tissues, maintains surgical planes, minimizes bleeding, decreases injury to collateral tissues, reduces surgical time, allows for utilization of less skilled assistants, and ensures complete excision in most cases. The noose technique is a versatile procedure that can be applied to extraocular cysts of any location or size both in children and adults. We demonstrate the technique in 3 different pediatric extraocular cysts.
