BACKGROUND: Extended endoscopic maxillectomy (Sturmann-Canfield procedure) allows full visualization of the maxillary sinus by sectioning the lacrimal duct and removing the medial part of the anterior maxillary wall. The aim of this study is to evaluate the morbidity of Sturmann-Canfield procedure in patients treated for inverted papilloma.
METHODOLOGY: The clinical records of all patients treated with a Sturmann-Canfield procedure for inverted papilloma from October 2000 to September 2015 at two teaching hospitals were reviewed. All patients were evaluated by nasal endoscopy and lacrimal system patency was assessed. Pre-maxillary cutaneous sensitivity was tested with a Semmes-Weinstein aesthesiometer and thermic stimulation. The SNOT-22 questionnaire was administered. Patients were also asked to report any other post-surgical complaints.
RESULTS: Fifty-nine patients were identified. Mean follow-up after surgery was 66.3 months. Mean SNOT-22 score was 5.94 (range 0-20); the majority of patients (86%) had a SNOT-22 symptom score of 3 or lower. Mucocoele occurred in 3 (5%) cases. Lacrimal pathway obstruction was observed in 7 (12%) patients. Fourteen (24%) patients complained of paraesthesia in the malar area; hypoesthesia was present in only 5 (8%) cases. Hypoesthesia in the region innervated by the anterior superior alveolar nerve was detected in 17 (29%) patients. One patient reported a slight depression of paralateronasal soft tissues.
CONCLUSIONS: Although nasal function outcomes and the results from SNOT-22 questionnaires were favourable, a high rate of neurologic and lacrimal complications was observed. Potential morbidity of the intervention, including the possibility of negative aesthetic sequelae, should be discussed during preoperative counselling.
