Abstract
Objective: 1) To assess the effectiveness of endoscopic surgery in the management of benign sinonasal tumors. 2) To compare our complication and recurrence rates with the literature.
Method: We performed a retrospective case note review of patients having endoscopic surgery for benign sinonasal tumors between 2001 to 2010. Our results in terms of success rate and complications were compared with similar studies in the literature. A systematic review was carried out including 5 case series studies and 1 meta-analysis.
Results: Fourteen patients were treated endoscopically (11 inverted papillomas, 1 pleomorphic adenoma, 1 oncocytoma, and 1 schwannoma). Exclusion criteria: Tumors eroding maxillary antrum, and extending into orbit, soft tissue, skull base, or intracranially. There were 9 men and 5 women; average age was 61 years (range, 42-80 years). Minor complications were encountered in 20% of patients. Average follow-up was 46 months (range, 13-120 months). The recurrence rate was 7% (1 patient with inverted papilloma, revised endoscopically). A review of a case series in the literature showed an identical recurrence rate between the 2 types of surgery (9%), and a meta-analysis showed greater difference (endoscopy 12% vs open 19.5%).
Conclusion: Endoscopic excision is an effective treatment modality and beneficial to patients with benign sinonasal tumors as it offers a similar, if not decreased, chance of recurrence with additional benefits of fewer complications and scarring.
