报道１９９０～１９９６年经手术治疗的２１例额筛窦粘液囊肿，经鼻外径路造口开放术１６例，经鼻腔内窥镜下单纯鼻内造口开放术５例，结果显示经鼻腔内窥镜下单纯鼻内造口开放术可克服鼻内径路视野不良的缺点，且中鼻道造口宽畅，鼻腔结构损伤轻微，术后面部无疤痕。 Reported 21 cases of ethmoid sinus mucinous cysts that were surgically treated from 1990 to 1996, 16 cases were treated with a nasal external diameter stoma, and 5 cases were treated with intranasal endoscopic intranasal neoplasty alone. The results showed that nasal cavity endoscopy was performed. The simple intranasal neoplasty under the microscope can overcome the shortcomings of nasal inner diameter and poor vision, and the mediotherapy of the nasal meatus is wide, the structure of the nasal cavity is slightly damaged, and there is no scar on the face after operation.
