title: Cryoextraction in the management of orbital tumors. An old technique revisited.
abstract: Four patients with relatively large orbital tumors are described. These patients had superomedial rhabdomyosarcoma, inferomedial cavernous hemangioma, lateral primitive neuroectodermal tumor, and superior neurofibroma, respectively. Continuing enlargement and encroachment upon vital ocular structures and suspicion of malignancy warranted surgical intervention. Following exposure of the anterior portions of these tumors, a cryoprobe was used for the complete removal of the mass. Cryoextraction greatly facilitates the excision of well-defined, solid, encapsulated, benign or malignant tumors excluding the lacrimal gland and thus minimizes trauma to adjacent tissues. More importantly, the tumor can be removed intact without capsular rupture and risk of tumor spill-over or hemorrhage. At the histopathological level, the application of a cryoprobe did not alter the microscopic structures of the lesions and did not cause any difficulty for histopathologic interpretation.
