Clinical study of 62 surgical cases of sinonasal papillomas

Sinonasal papilloma is a benign tumor. But it is known for frequent local recurrence, a tendency to invade to bone tissue and transformation to malignancy. Such characteristics make complete resection of the tumor mandatory. We outline 62 surgical cases of sinonasal papilloma over the last 10 years. Mean age was 56 years (19-84). Chief complaints were unilateral nasal obstruction in 49 cases (79%). The site of origin was mostly on the lateral wall of the nasal cavity. According to the classification by Krouse, 4 cases were in T1, 27 in T2, 28 in T3, 3 in T4. The pathological diagnosis was mostly inverted papilloma. Recurrences were noted in 11 cases (18%). We operated on all cases. 29 cases underwent medial maxillectomy after Denker and 34 received ESS (6 cases underwent EMM). Recently, a number of reports have advocated endoscopic sinus surgery (ESS) to minimize invasiveness. But it is difficult to resect the tumor completely by ESS and therefore there is a chance of local recurrence. The optimal approach to appropriate tumor resection should be chosen.
