Le Fort type I osteotomy is a fracture that extends from the pyriform aperture to each of the pterygoid plates, resulting in the detachment of the upper jaw from the cranial base. A retrospective study was conducted on 12 patients with juvenile nasopharyngeal angiofibroma (JNA) who underwent the Le Fort type I approach. Preoperatively, all cases were investigated with computed tomographic scans with contrast and angiography with embolisation. This paper highlights the surgical technique, results and treatment morbidity. The average age of the patients was 21 years, average duration of surgery was 3.2h and average blood loss was 550 ml. All cases had significant symptomatic improvement postoperatively. At 1 year follow up, the authors encountered dental malocclusion in one case and no recurrence of JNA. The Le Fort I osteotomy approach is an excellent approach for the excision of JNA because it allows good surgical exposure, better haemostasis, is cosmetically more acceptable and has a very low morbidity.
Le Fort Ⅰ型骨切开术是一种从梨状孔延伸到每一个翼板的骨折,导致上颌骨与颅底分离。对 12 例接受 Le Fort Ⅰ型入路的青少年鼻咽血管纤维瘤(JNA)患者进行了回顾性研究。所有病例均在术前进行了增强 CT 扫描和血管造影栓塞检查。本文重点介绍了手术技术、结果和治疗发病率。患者的平均年龄为 21 岁,平均手术时间为 3.2 小时,平均失血量为 550 毫升。所有病例术后均有明显症状改善。1 年随访时,作者发现 1 例存在牙咬合不正,无 JNA 复发。Le Fort Ⅰ型骨切开术是一种很好的 JNA 切除术方法,因为它可以提供良好的手术暴露,更好的止血效果,更美观,发病率非常低。
