Nasal reconstruction in surgery of the anterior skull base

We sought to evaluate the effectiveness of a number of surgical maneuvers in nasal reconstruction of a diverse population of patients undergoing skull base surgery. Study design We conducted a retrospective review of a cohort of patients undergoing nasal reconstruction during surgery of the anterior skull base and craniovertebral junction.

All patients undergoing skull base surgery and nasal reconstruction by the senior author (Y.D.) with a minimum follow-up of 12 months from 1997 to 2001 were evaluated. Preoperative and postoperative photographs and clinical evaluation were examined in detail with particular attention focused on the nasal complex.

A total of 47 patients were evaluated for this study, including those who had undergone anterior craniofacial resections (n = 14), Le Fort osteotomies (n = 5), subcranial approaches (n = 10), maxillotomies (n = 8), and midfacial disassemblies (n = 10). Primary calvarial bone graft reconstruction of the anterior craniofacial group was facilitated with the use of positioning plates and resuspension of the upper lateral cartilages when available. In contradistinction to secondary bone grafting, dorsal grafts in this group extended to the native nasal bone length. A small overlay bone graft was thought to be necessary when the nasal root was osteotomized in conjunction with the orbital and/or maxillary segments to maintain dorsal height in the long term. Le Fort osteotomy patients require refixation of the septum to the anterior nasal spine region for stability.

Use of the techniques outlined in this article appears to be associated with gratifying long-term nasal form in reconstruction of the anterior skull base.
