随着鼻内镜技术的广泛应用和不断完善,鼻内镜手术治疗鼻窦良性病变已日趋成熟。但对处理上颌窦前壁、前内下壁及底壁的病变,仍有局限性。目前多采用传统Caldwell-Luc径路联合鼻内镜手术治疗上颌窦病变〔1〕。周兵等〔2-3〕报道了鼻内镜下保留鼻泪管和下鼻甲的鼻腔外侧壁切开进 With the wide application and continuous improvement of endoscopic sinus surgery, endoscopic sinus surgery has become increasingly mature benign lesions. However, the treatment of the anterior wall of the maxillary sinus, anterior inferior wall and the wall of the lesion, there are still limitations. Currently more use of traditional Caldwell-Luc pathway combined with endoscopic sinus surgery for the treatment of maxillary sinus lesions [1]. Zhou Bing et al [2-3] reported nasal endoscopic nasolacrimal duct and nasal turbinate to keep the lateral wall cut into
