Abstract

Background: Inverted Papilloma arises from the lateral wall of nose and is common in maxillary sinus. It is locally invasive, can recur and has malignant potential. Endoscopic medial maxillectomy is the preferred choice. Materials and Methods: This prospective study was conducted in the department of Otolaryngology, Nobel Medical College and Teaching Hospital, Biratnagar from June 2015 to June 2018. A total of 26 patients were included in the study, after informed consent and ethical clearance. Staging was done by Krouse method after imaging studies and preoperative endoscopic biopsy was performed. These patients then underwent endoscopic medial maxillectomy. All the data were collected in excel spreadsheet and analyzed in SPSS software. Results: Out of a total of 26 patients, male: female ratio was 1.6:1, with 16 male and 10female. Average age was 40.5 years (25-72years). According to Krouse staging, 2 patients were in Stage I, 7 patients in Stage II and 17 patients in Stage III. IP mostly involved the lateral wall of nose.  Unilateral nasal obstruction was the commonest presenting symptom. The commonest post-operative complication was nasal crusting. Most of the patients were treated with simple endoscopic medial maxillectomy. Conclusion: Inverted Papilloma is common in male in their 4th decade of life with lateral wall of the nose being mostly affected. Most patients were in stage III of Krouse’s staging system. Simple endoscopic medial maxillectomy was the commonest procedure.

内翻性乳头状瘤:我们在尼泊尔三级护理中心内窥镜内颌切除术的经验及其结果
背景:内翻性乳头状瘤起源于鼻侧壁,常见于上颌窦。它具有局部侵袭性,可复发,具有恶性潜能。内镜下上颌内侧切除术是首选。材料和方法:这项前瞻性研究于2015年6月至2018年6月在比拉特纳加的诺贝尔医学院和教学医院耳鼻咽喉科进行。在知情同意和伦理审查后,共有26名患者被纳入研究。在进行影像学研究和术前内镜活检后,采用Krouse方法进行分期。这些患者随后接受了内窥镜上颌内侧切除术。所有数据收集在excel电子表格中,并在SPSS软件中进行分析。结果:26例患者中,男女比例为1.6:1,其中男性16例,女性10例。平均年龄40.5岁(25-72岁)。根据Krouse分期,I期2例,II期7例,III期17例。IP主要累及鼻侧壁。单侧鼻腔阻塞是最常见的症状。术后最常见的并发症是鼻腔结痂。大多数患者接受了简单的内窥镜上颌内侧切除术。结论:倒置性乳头状瘤在40多岁的男性中很常见,鼻侧壁受影响最大。大多数患者处于克罗斯分期系统的第三阶段。简单的内窥镜上颌内侧切除术是最常见的手术。
