测量１００侧（５０例）颅骨的筛上颌窦板的高度、筛上颌窦板上缘至后筛顶的高度。鼻前棘至后筛顶后缘的距离及角度，观察中鼻甲的走行及附着，筛骨水平板的形态及后筛窦的分度及变异，为临床手术提供了一定的解剖学依据。应用显微镜从上颌窦、鼻内进路行颌筛根治术２５例，术后筛窦腔宽敞光滑，引流通畅。７５％患者嗅觉有不同程度恢复，９４％患者头痛头昏症状好转，未发现严重的手术并发症。
The height of the sieve maxillary sinus plate was measured on 100 sides (50 cases) skull, and the height of the upper edge of the maxillary sinus plate to the top of the screen was measured. The distance and angle between the anterior nasal spine and the posterior edge of the top of the screen, observing the movement and attachment of the middle turbinate, the morphology of the ethmoid bone plate and the index and variation of posterior ethmoid sinus provide some anatomic evidence for clinical operation. The application of microscope from the maxillary sinus, nasal approach and maxillofacial radical mastectomy in 25 cases, after the ethmoid sinus cavity spacious and smooth, smooth drainage. 75% of patients with different degrees of recovery of the sense of smell, 94% of patients with dizziness headache symptoms improved, no serious complications were found.
