Location-Based Surgical Approaches for Orbital Tumor Resection

Purpose: We investigated the site of tumor development, tumor tissue morphology, surgical approach, and method of selection and indications for a particular surgical method in patients who underwent intraorbital tumor excision. Methods: Surgical methods employed for orbital tumors at our facility between January 2010 and December 2021 were investigated. The relationship between the site of tumor development and surgical approaches, including osteotomy, was investigated. Results: The study included 92 patients, of whom 35 required osteotomy. Superficial orbital tumors were excised using a percutaneous or transconjunctival approach. Craniotomy was necessary to excise deep orbital tumors that developed above the optic nerve. Tumors that developed on the lateral side of the optic nerve were excised using lateral orbitotomy without craniotomy. Deep orbital tumors that developed on the medial and lower sides were excised by extending orbital osteotomy to adjacent sites as needed, for example, a combination of lateral orbitotomy and inferior rim osteotomy. single osteotomy or concomitant osteotomy at several sites, as needed.
