【摘要】：目的研究钩突与泪囊窝的影像解剖及其在鼻内镜下泪囊鼻腔开放术中的意义。方法分析80例鼻窦薄层CT扫描的影像资料,测量泪囊窝骨质厚度,观察钩突与泪囊窝、泪骨的解剖关系;18例泪囊炎患者行鼻内镜下鼻腔泪囊开放术,通过钩突中、下部附着定位泪骨,行泪骨入路向上扩大开放泪囊,记录手术过程,观察其可行性。结果泪囊窝前上部及后下部骨质的厚度为(2.96±0.33)mm,(0.02±0.01)mm(P0.05),泪囊窝前上部骨质厚度大于后下部,差异有统计意义;在泪囊窝下端,钩突往往附于泪囊窝后部,往上逐渐靠前,于中部连接于泪骨或上颌骨额突,上部连接于中鼻甲外侧或眶纸板上。16例慢性泪囊炎患者在钩突前方成功经泪骨切开向上扩大暴露泪囊,2例钩突上部附于上颌骨额突太靠前者予钩突上部切除后暴露泪囊。结论准确认识钩突与泪骨、泪囊窝的解剖关系,有助于鼻内镜下行泪囊鼻腔开放时定位、暴露泪囊,避免手术并发症。
[Abstract]:Objective To study the imaging anatomy of uncinate process and lacrimal sac fossa and its significance in endoscopic dacryocystorhinostomy.Methods The imaging data of 80 cases of nasal sinus with thin-slice CT scanning were analyzed.The thickness of lacrimal sac fossa bone was measured.The anatomical relationship between uncinate process and lacrimal sac fossa and lacrimal bone was observed.18 cases of dacryocystitis underwent endoscopic dacryocystorhinostomy through uncinate process. Results The thickness of bone in anterior and posterior part of lacrimal sac fossa was (2.96 16 cases of chronic dacryocystitis were successfully exposed by lacrimal sac incision in front of uncinate process, 2 cases of uncinate process attached to the maxillary frontal process too close to the anterior were exposed after upper uncinate process excision. Conclusion Accurate understanding of the anatomical relationship between uncinate process and lacrimal bone and lacrimal sac fossa is helpful to locate the lacrimal sac and expose the lacrimal sac in nasal opening under nasal endoscopy.
