Abstract

Object. In this study, the authors evaluated the efficacy and safety of modified orbitozygomatic craniotomy for resection of craniopharyngioma in children. Methods. A prospective, institutional review board-approved database was retrospectively reviewed for pediatric patients undergoing craniopharyngioma resection performed by a single surgeon. Results. Ten patients underwent craniopharyngioma resection surgery between July 2000 and January 2006 (4 girls and 6 boys, ages 1.5-17 years). Nine patients presented to the authors' institution, and 1 patient was referred after surgery and radiation therapy were administered elsewhere. Nine patients presented with visual field deficits (2 with unilateral or bilateral light perception only) and 5 with endocrine dysfunction. Eight patients had large tumors that significantly displaced the optic chiasm and hypothalamus. All patients underwent a modified frontotemporal orbitozygomatic osteotomy in a single piece. The lamina terminalis was opened in 4 patients with third ventricular extension. One patient required a staged transsphenoidal operation to remove residual tumor in the sella turcica, and 1 patient underwent a contralateral subtemporal approach to resect a daughter lesion in the prepontine cistern. Complete radiographic resection was achieved in all patients. Follow-up averaged 55 months (range 12-95 months). Vision was improved in 8 patients and remained stable in 2. All patients had postoperative endocrine dysfunction. One patient experienced transient cranial nerve IV palsy and 1 suffered a small caudate stroke 5 months after surgery without sequelae. Two patients experienced polyphagia and weight gain without other symptoms of hypothalamic dysfunction. There were no other new neurological deficits. Conclusions. Modified orbitozygomatic craniotomy provides excellent exposure of the suprasellar region with minimal brain retraction, allowing complete resection of craniopharyngiomas with good visual and neurological results.
