All lesions were isolated to the MIS, pathology addressed included: cavernous hemangioma (6), schwannoma (4), lymphoma (4), inflammatory pseudotumor (2), chronic invasive fungal sinusitis (2), and metastatic disease (2). Either a biopsy (10\/20) or a complete resection (10\/20) was performed. In all cases, the MIS was accessed via an endonasal corridor between the medial and inferior rectus muscles. Retraction and safe, intra\u2010orbital dissection of the lesion was performed using a two\u2010surgeon, multi\u2010handed technique. Gross total resection of benign lesions was achieved in 90% (9\/10) of cases; a pathologic diagnosis was achieved in 100% (10\/10) of biopsy cases. No orbital reconstruction was required. Visual acuity returned to normal in 80% (8\/10) of planned resection cases and postoperative diplopia resolved by 3\u2009months in 90%.
