The Usefulness of Endoscopic Management in Benign Sinonasal Tumors

ABSTRACT

BACKGROUND AND OBJECTIVES: There are increasing evidence suggesting that the endoscopic approach can be used successfully for the treatment of benign sinonasal tumors. In the present study, we reviewed a 12-year experience of our institution for endoscopic management of benign sinonasal tumors. MATERIALS AND METHODS: We retrospectively reviewed the medical records and radiologic findings of 185 patients who underwent endonasal endoscopic resection of benign sinonasal tumors at the Catholic Medical Center between 1996 and 2007. RESULT: Inverted papilloma (119 cases, 64.3%) was most common, followed by hemangioma (14 cases), pyogenic granuloma (11 cases), angiofibroma (9 cases), and osteoma (7 cases). The most common symptom was nasal obstruction (70.8%). Sixteen cases (8.6%) recurred after endoscopic resection (12 cases of inverted papilloma, 2 cases of ossifying fibroma, and 2 cases of fibrous dysplasia). No major complications were reported. CONCLUSION: Endoscopic approach allows for successful surgical outcomes and good cosmetic effects among patients with benign sinonasal tumors. We suggest that, in selected cases, benign tumors involving the sinonasal tract can be safely and radically removed using the endoscopic technique.
