Abstract

Objectives This study aims to compare the surgical and functional outcomes of superolateral orbitotomy (group A) and conventional superior orbitotomy (group B) for benign orbital tumors.

Design A retrospective review of 31 consecutive orbital tumor surgeries with the fronto-orbital approach was conducted.

Setting Procedures were performed at two institutions by a single surgeon.

Participants A total of 31 orbital tumor patients participated in this study. Overall, 11 intraconal and 2 extraconal tumors in group A and 11 intraconal and 7 extraconal tumors in group B were resected by superolateral orbitotomy, respectively.

Main Outcome Measures Demographic information, pre- and postoperative neurological findings and neuroimaging data, and pathological data were collected. Surgical and functional outcomes were compared and statistically analyzed between the two different surgical procedures.

Results The surgical outcomes were not significantly different between the two groups. In patients with intraconal tumors, the functional outcome was significantly better in group A than in group B.

Conclusion Superolateral orbitotomy provides better functional outcomes.
