摘要
目的为鼻内窥镜下鼻腔泪囊吻合术提供解剖学指导。方法对14例(28侧)成人尸头的泪囊窝内侧壁的骨性结构构成、泪囊窝与前组筛窦、中鼻甲腋的解剖学关系进行观察,并测量泪囊窝内侧壁前后部骨质厚度。结果泪囊窝内侧壁均由上颌骨额突与泪骨组成。泪囊窝中部以下泪骨约大于上颌骨额突,中部以上相反。前半部骨质平均厚度2.96mm,后半部平均厚度0.02mm。将以上二者解剖关系分为3型,Ⅰ型10侧,Ⅱ型13侧,Ⅲ型5侧。泪囊大部分位于中鼻甲腋前下方,小部分位于上方。结论手术造孔位置选择泪囊窝中下方易于成功。
Objective To provide anatomic guidance to endoscopic transnasal dacryocystorhinostomy. Methods Fourteen heads of adult cadavers （with 28 sides） were studied including the structure of inner wall of lacrimal sac fossa,the anatomical relationship between fossa of the lacrimal sac, anterior ethmoid sinus and insertion of the front of middle turbinate. The thickness of inner walls of anterior and posterior aspects of lacrimal fossa were measured. Results The inner wall of lacrimal fossa was made up of the frontal portion of maxillary bone and lacrimal bone. The lower half of lacrimal fossa was greater than the frontal protrusion of maxillary bone. The reverse was true for the upper half of lacrimal fossa. The average bony thickness of the anterior part was 2.96 mm while the bony thickness of the posterior half was 0.02 mm. In the anatomic relationship between fossa of lacrimal sac and anterior ethmold sinus, type Ⅰ accounted for 35.7%, type Ⅱ 46.4% and type Ⅲ 17.9%. Majority of the lacrimal sacs were situated in front and below the middle turbinate while the minority was situated above the middle turbinate. Conclusion It makes success easy to choose the opening location at the middle to lower portion of the lacrimal fossa i. e. below the horizontal line of the middle turbinate.
