显微颌筛根治术的应用解剖和临床研究

THE SURGICAL ANATOMICAL AND CLINICAL STUDIES OF MAXILLARY-ETHMOIDECTOMY COMBINED INTRANASAL AND TRANSANTRAL APPROACHS BY MICROSCOPIC TECHNIQUE

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。

Chronic rhinosinusitis and nasal polyps are the most common lesion encountered in the nose.There are still many uncovered questions concerning their treatment,especially the operation.Forobtaining the bets result,the height of maxillary-ethmoid and the height from the up-edgeof maxillary-ethmoid plate to the roof of posterior ethmoid were measured.The distance fromthe nasal still to the posterior roof of posterior ethmoid in fifty skulis.In the same time,25cases of maxillary-ethmoidectomy were performed by combined transnasal and maxillary ap-proaches,for chronic rhinosinusitis and nasal polyps using microsurgery technique.The fol-low-up of cases showed good results and no setrious complication was found.
