The purpose of this study is to present the technique of the extended subcranial approach to the anterior skull base, and to review the results of 48 patients who underwent the procedure. A retrospective review was conducted on the records of 48 patients who underwent this procedure for the treatment of various neoplasms originating in the nasal cavity, nasopharynx, paranasal sinuses, orbit, or meninges, in an academic tertiary referral medical center. Preoperative patient evaluation, surgical technique, and complications are also reviewed.Sixteen patients had malignant tumors and 32 patients had benign tumors. There was one perioperative death (fulminant meningitis on postoperative day 28). Significant complications consisted of meningitis occurring in 2 patients and 5 cases of osteoradionecrosis with bone cutaneous fistula. The most common late complication was anosmia (in 27 patients).Based on this review, we feel that the extended subcranial approach to the anterior skull base is a safe, versatile, and effective procedure for the surgical treatment of tumors that involve the anterior skull base.
