Abstract

OBJECTIVE: To introduce and evaluate the effectiveness and safety of transnasal endoscopic anterior and medial maxillectomy (TEAMM) in the treatment of Krouse stage III inverted papilloma (IP) originating from the maxillary sinus. METHODS: A retrospective chart review was performed for 33 patients with Krouse stage III IP undergoing TEAMM in our hospital between 2003 and 2008. RESULTS: Tumors were completely resected through TEAMM. Sixteen cases had type I TEAMM, during which the nasolacrimal duct was preserved; 17 had type II TEAMM, during which the nasolacrimal duct was resected. The inferior turbinate was partially preserved in 26 cases. Patients were followed for a mean of 40.4 months. Recurrence developed in 2 patients, dry nose syndrome in 5 patients, and epiphora in 1 patient. Squamous cell carcinoma occurred in 1 patient. CONCLUSIONS: TEAMM is an effective and safe technique in the management of Krouse stage III IP and provides good exposure of operative cavities during follow-up.
