鼻丘气房和额隐窝内侧壁的解剖观测与手术切除

为提高鼻窦炎、鼻息肉的手术效果，对尸头和颅骨的鼻外侧壁骨结构进行解剖观测。结果示：中鼻甲垂直部前端附着处与筛顶间有约1．5cm的距离，此间即为鼻丘气房和额隐窝的所在部位，而鼻丘气房内侧壁恰好位于中鼻甲起端附着处上方。提示手术时切除中鼻甲起端附着缘上后方骨质，就开放了鼻丘和额隐窝的内侧壁。然后小心清除其内的病变组织，就能保持鼻窦开放，引流通畅，恢复通气，减少鼻息肉复发。并经对15例患者术后随访0．5～1．5年，均获满意疗效而得到证实。

Anatomy and operation of agger nasi ethmoidal cells and frontal recess

To reduce postoperative recurrency of nasal polyps and sinusitis,the anatomy of lateral wall of nasal cavity was studied in body head. It was found that there was a considerable wide area between the anterior attachman of the middle turbinate and the roof of ethmoidal sinus,just where the agger nasi ethmoidal cells and frontal recess lying. And also the medial wall of agger nasi ethmoidal cell is just above the anterior attachment of middle turbinate. In our operations,the bony structure above the anterior attachment of middle turbinate was resected to open the medial wall of agger nasi ethmoidal cells and the frontal recess,the lesions in them was removed carefully to reobtain a well drainge. 15 cases were followed up for 0. 5 to 1.5 years and the result was satisfying.
