To summarize and analyze the surgical treatment of lateral sellar compartment cavernoma (LSCC). The clinical data of 102 patients with LSCC who underwent surgical treatment from 1958 to 2006, 2 males and 80 females, aged 43.5 (11 approximately 69), were collected and analyzed. The operation patterns were divided into 4 stages based on the understanding of LSCC: first stage (1958 approximately 1988, with 32 cases) during which diagnosis was mainly bases on X-ray plain films, CT, and ordinary cerebral angiography, and most of the tumors were partially excised; second stage (1989 approximately 1997, with 18 cases) during which MRI, DSA, and microsurgery were widely used; third stage (1998 approximately 2003, with 36 cases) during which the neurological anatomy of the LSC and pathology of LSCC made headway, however, intra-operational bleeding was still a problem, and fourth stage (2004 approximately 2006, with 16 cases) during which relevant models were basically understood. Post-operative MRI shed that the tumor complete resection rates of the 4 stages were 4/32, 5/18, 17/36, and 12/16, and the subtotal resection rates were 3/32, 4/18, 10/36, and 2/16 respectively. The rest of the tumors were all partially removed. Not only the intra-operative blood loss but also the cranial nerve morbidity rate decreased dramatically in the 4th stage. The main postoperative complications included oculomotor nerve paralysis, abducent nerve palsy, and trigeminal nerve damages. No operation-related death occurred. Following the progress of LSCC study, the treatment of LSCC becomes mature. Radical removal of LSCC may be the best choice for LSCC patients by epidural approach via the skull base craniotomy with induced hypotension.
