Objective:
To evaluate the effect of endoscopic resection and traditional procedure in the management of sinonasal inverted papilloma with a staging system based on endoscopic examination of the nasal cavity and computed tomography (CT) scan evaluation.
Methods:
Two hundred and twenty-two patients with sinonasal inverted papilloma treated surgically were retrospectively reviewed. There were 23 cases in stage I; 119 cases in stage II; 65 cases in stage III and 15 cases in stage IV. Among these patients, 122 cases were treated endoscopically; 100 cases were treated by traditional surgical techniques, including 56 cases with lateral rhinotomy; 27 cases with intranasal approach and 15 cases with Caldwell-Luc technique.
Results:
The inverted papilloma was removed completely and no serious complications were encountered by all four kinds of techniques used. With an average follow-up of 3. 8 years, the recurrence rate for endoscopic group was 14.8% (18/122, four patients were in group I; nine in group II; four in group III; and one patient in group IV. No recurrence was found in group III who underwent endoscopic excision combined with Caldwell-Luc procedure. The recurrence rate for lateral rhinotomy group was 33. 9% (19/56, one patients in group I; six in group II; nine in group III; three in group IV). The recurrence rate for intranasal approach group was 51.9% (14/27, two patients were in group I; ten in group II; and two in group III). The recurrence rate for Caldwell-Luc procedure group was 29.4% (5/17, all in group II and group III). Regardless of approaches, patients who had primary resection had a recurrence of 26. 8%, whereas those with secondary resection had a recurrence of 20. 9% (P = 0.39).
Conclusions:
The endoscopic surgical technique was proved to be a better method for treating sinonasal inverted papilloma in stage I and stage II. Better results for patients in stage III would be achieved by combining endoscopic technique with Caldwell-Luc procedure. As to patients with stage IV, radical external approaches should be considered.
