Surgery of inverted papillomas under endoscopic control.
Six centers cooperated in a retrospective study on endoscopic surgical resection of Papillomas of the nose and paranasal sinuses in order to assess both the efficiency and the safety of this kind of surgical approach. From 1991 till march 2000, 87 cases of Papillomas resections under--at least partially--endoscopic control were gathered, among which 85 were Inverted Papillomas (IP), 2 were Exophytic Papilloma (EP) and one was IP coexisting with Collumnar Cell Papilloma (CCP). Malignant transformation was found out in 3 cases of IP. Regarding the 85 patients with IP demographics are as follows: 61 males, 24 females, with a mean age of 58.4 years (STDV: 13.96) in a range from 27 to 92 years. The mean follow-up was of 41.9 months with range of 1-120 months. Fifteen recurrences occurred that were treated by revision surgery either under endoscopic control or by limited external approach. The mean time for recurrences to occur was 8.07 months with range of 1-24 months. The three patients with malignant transformation underwent postoperative radiation therapy. All of the patients are free of recurrence, however for some of them the follow-up is too short to definitely assess their free of disease status. The role of modern diagnostic tools in medical imaging--CAT and MRI--in order to assess clearly the limits of the tumors and to enhance the efficiency and the safety in the choice of a surgical approach is pointed out. The stress is put on the need for radical excision under endoscopic control which can be combined with the Caldwell-Luc transantral approach or with frontal trepanation for the cure of tumors impossible to be reached under endoscopic control only. Irrespective of the tumor extent and of the approaches that was used for excision a close endoscopic follow-up still remain mandatory, by trained surgeons, in the long term management of IP. Biopsies, CAT and/or MRI must be performed in any case with recurrence suspicion.
