Rhinosporidiosis is a rare, chronic, granulomatous infection of the mucous membranes that mainly involves the nose and nasopharynx; it occasionally involves the pharynx, conjunctiva, larynx, trachea and, rarely, the skin. The characteristic clinical features of this disease include the formation of painless polyps in the nasal mucosa or the nasopharynx that bleed easily on touch. At our center, excision of the lesion with a Le Fort I osteotomy is carried out in patients (1) in whom two or more previous attempts at excision of biopsy-proven rhinosporidiosis arising from the nasal mucosa was carried out or (2) in whom the rhinosporidiosis arises from the nasophayrngeal mucosa and/or extranasal sites. In this article we retrospectively present 7 cases in which, according to our inclusion criteria, complete excision of the lesion was carried out with a Le Fort I osteotomy. Excellent visualization of the entire maxillary and ethmoidal air cells after the down-fracture of the maxilla helped in the total removal of the lesions. Most of these lesions had multiple points of origin through the nasal, maxillary, and ethmoidal mucosa; the excellent visualization enabled direct cauterization of all these points of origin. The mean follow-up period was 7.96 years, and all patients were disease-free by the time the study was prepared. This article presents details of the treatment protocol and technique followed at our center for the treatment of nasopharyngeal rhinosporidiosis and the details of long-term follow-up. Through this study we hope to prove the efficacy of Le Fort I osteotomy in the definitive management of nasopharyngeal rhinosporidiosis.
鼻孢子虫病是一种罕见的慢性肉芽肿性黏膜感染,主要累及鼻腔和鼻咽部;偶尔累及咽部、结膜、喉部、气管,极少累及皮肤。该病的特征性临床症状包括在鼻黏膜或鼻咽部形成无痛性息肉,触之易出血。在我们中心,对于以下患者采用勒福Ⅰ型截骨术切除病变:(1)曾两次或两次以上尝试切除经活检证实源于鼻黏膜的鼻孢子虫病但未成功的患者;(2)鼻孢子虫病源于鼻咽部黏膜和/或鼻外部位的患者。在本文中,我们回顾性呈现了7例根据纳入标准采用勒福Ⅰ型截骨术完全切除病变的病例。上颌骨向下折断后对上颌窦和筛窦气房的良好视野有助于彻底清除病变。这些病变大多通过鼻腔、上颌窦和筛窦黏膜有多个起源点;良好的视野便于对所有这些起源点进行直接烧灼。平均随访期为7.96年,在撰写本研究时所有患者均无疾病。本文介绍了我们中心治疗鼻咽部鼻孢子虫病所采用治疗方案和技术的细节以及长期随访的细节。通过本研究,我们希望证明勒福Ⅰ型截骨术在鼻咽部鼻孢子虫病确定性治疗中的疗效。
