上颌窦的良性病变主要包括炎性病变或良性肿瘤性病变，在鼻内镜技术出现之前，治疗方式主要为 Cald-well-Luc 术式，即经典上颌窦根治术。随着鼻内镜技术的发展应用，一些上颌窦良性病变手术可经下鼻道或中鼻道完成，临床上已经基本上代替了 Caldwell-Luc 术式，一些开放性的手术也在鼻内镜辅助下有所改进。鼻内镜技术优势在于有良好的手术视野及对患者所造成的创伤小，可以最大程度的保留下鼻甲、鼻泪管等生理结构组织。在鼻内镜技术日益成熟的今天，许多术式在不断的发展创新，该文通过文献复习，对鼻内镜下上颌窦病变的手术入路进行综述。“,”The benign lesions of maxillary sinus mainly include inflammatory lesions and benign tumorous lesions. Caldwell-Luc operation,the radical maxillary sinusotomy,was the major treatment for the benign lesions of maxillary sinus before the nasal endoscopic surgery was used.With the development of nasal endoscopy technology,basically replaced Caldwell-Luc operation,some operation for the benign lesions of maxillary sinus can be performed by endosco-py via the middle or inferior meatus approach.And open surgery with nasal endoscopy-assistedhas been improved as well.Nasal endoscopic surgery has the advantages of well surgical field,small trauma and keeping the organizational structure of inferior turbinate and nasolacrimal duct.With nasal endoscopic surgery becoming more mature,operation continues to develop with innovation.This paper will review the surgical approachs of nasal endoscopic surgery for maxillary sinus lesions.
