Even though endoscopic removal of inverted papillomas has gained popularity, many studies advocate supplementary external approaches. The impact of including the current surgical staging system into the pre-operative clinical and radiological assessment has not been systematically evaluated. We present our experience with total endoscopic management of inverted papillomas and compare the accuracy of the pre-operative predicted extent of surgery, with the actually performed surgery. From 1997 to 2005 data from 51 patients with inverted papillomas were prospectively collected and subsequently reviewed. All have been operated on endoscopically without an external approach. The overall recurrence rate was 3.9 per cent. Pre-operative prediction of extent of surgery was accurate in 26 of 51 (51 per cent). The main reasons for the inaccurate pre-operative prediction were the variable sizes and locations of the inverted papilloma bases, particularly in the maxillary sinus and the frontal recess. Our results encourage us to recommend endoscopic management as the standard treatment of benign inverted papillomas.
尽管内镜下切除内翻性乳头状瘤已越来越普遍，但许多研究主张采用辅助性外部手术方法。将当前的手术分期系统纳入术前临床和影像学评估的影响尚未得到系统评价。我们介绍了我们在内翻性乳头状瘤全内镜治疗方面的经验，并比较了术前预测手术范围与实际手术范围的准确性。1997年至2005年，前瞻性收集并随后回顾了51例内翻性乳头状瘤患者的数据。所有患者均接受了内镜手术，未采用外部手术方法。总体复发率为3.9%。51例患者中有26例（51%）术前对手术范围的预测准确。术前预测不准确的主要原因是内翻性乳头状瘤基底的大小和位置各不相同，尤其是在上颌窦和额隐窝。我们的结果促使我们推荐内镜治疗作为良性内翻性乳头状瘤的标准治疗方法。
