Abstract
INTRODUCTION: A medial maxillectomy (MM) consists of a complete resection of the medial wall of the maxillary sinus. Traditionally the surgery is performed via an open approach. With more familiarity and expertise in endoscopic sinus surgery the endonasal approach is feasible. OBJECTIVE: To expose the surgical technique and report the results of endonasal endoscopic MM in a series of 6 consecutive patients. MATERIALS AND METHODS: Between August 2006 and October 2009, 6 patients were operated with this procedure. All were men. The mean age was 62-year-old (range: 43-83). In 5 cases, the surgery was performed for inverted papillomas confined to the maxillary sinus. In one case it was a primary surgery whereas it was a revision surgery for the others. The sixth patient was operated for a solitary extramedullary plasmocytoma inserted on the intersinonasal wall persistent after an external radiation therapy. RESULTS: All the patients are free of disease at the time of writing with a mean follow-up of 18,2 months (range: 9-38). This has been confirmed by a nasal endoscopy and CT scans. There were no major per or postoperative complications. Patients suffered from crusting for at least 6 months postoperatively necessitating daily nasal douches. One patient is still complaining of intermittent epiphora when he is exposed to wind. CONCLUSION: Endoscopic MM can be successfully performed for the resection of expanding processes involving the maxillary sinus and/or the intersinonasal wall. Compared to open approaches, it seems to be as effective with less postoperative morbidity. An important technical point is to do the anterior osteotomy in front of the nasolacrimal duct in order to expose the prelacrimal recess that is typically an area for possible recurrence. Exact determination of the tumor attachment during the surgery is another key point for success.
