Inverted papillomas are rare, benign epithelial tumours of the nasal cavity and paranasal sinuses. To evaluate recurrence rates and rates of malignant transformation by lateral rhinotomy and midfacial degloving approaches for inverted papillomas. Retrospective case series, done at Manipal Teaching Hospital, Pokhara, over an 8-year period from 2000 to 2008. We did a review of 20 cases of T3 inverted papilloma. All patients initially underwent nasal biopsy for confirmation of the diagnosis and pre-operative C.T. scan for tumour staging. 10 patients who had a medial maxillectomy by lateral rhinotomy approach were assigned group I, while 10 who had a medial maxillectomy by mid-facial degloving approach were placed under group II. There were 7 males and 3 females in both group I and group II. Age ranged from 50 to 70 years with a mean age of 62.3 years for group I and 59.8 years for group II. Commonest presenting complaint was unilateral nasal obstruction (60.0% in group I, 80.0% in group II). The mean follow up period was 19.5 months for group I and 16.5 months for group II. Recurrence rate and malignant transformation was 10.0% each for both groups. There was no significant difference between the 2 groups in these findings. Lateral rhinotomy and mid-facial degloving approaches have similar recurrence rates in T3 inverted papillomas but mid-facial degloving has the advantage of no external facial scar and bilateral exposure.
内翻性乳头状瘤是鼻腔和鼻窦罕见的良性上皮性肿瘤。评估经鼻侧切开术和面中部掀翻术治疗内翻性乳头状瘤的复发率和恶变率。回顾性病例系列研究，于2000年至2008年在博卡拉马尼帕尔教学医院进行。我们回顾了20例T3期内翻性乳头状瘤病例。所有患者最初均接受鼻活检以确诊，并进行术前CT扫描以进行肿瘤分期。10例行鼻侧切开术式上颌骨内侧切除术的患者被分为I组，10例行面中部掀翻术式上颌骨内侧切除术的患者被分为II组。I组和II组均有7例男性和3例女性。年龄范围为50至70岁，I组平均年龄为62.3岁，II组平均年龄为59.8岁。最常见的主诉是单侧鼻塞（I组为60.0%，II组为80.0%）。I组平均随访期为19.5个月，II组平均随访期为16.5个月。两组的复发率和恶变率均为10.0%。两组在这些结果上无显著差异。鼻侧切开术和面中部掀翻术治疗T3期内翻性乳头状瘤的复发率相似，但面中部掀翻术具有无面部外部瘢痕和双侧暴露的优势。
