目的 :为临床开展鼻窦内窥镜手术提供外科手术解剖学依据。方法 :在 2 0具 40侧经防腐处理的完整成人尸头标本上观测筛泡气化发育的情况 ,观察额窦及前中筛气房窦口引流情况。结果 :额窦向中鼻道引流占 87.5 % (3 5侧 ) ;向筛漏斗引流占 10 .0 % (4侧 ) ;鼻丘向中鼻道引流占 90 .0 % (3 6侧 ) ;向筛漏斗引流占 10 .0 % (4侧 ) ;额隐窝向中鼻道引流占 15 .0 % (6侧 ) ;向筛漏斗引流占 10 .0 % (4侧 ) ;向侧窦引流占75 % (3 0侧 ) ;筛泡向筛漏斗引流占 2 5 .0 % (10侧 ) ;向侧窦引流占 75 .0 % (3 0侧 )。结论 :钩突和筛泡的解剖异常直接影响前组鼻窦的通气引流 ,从而导致前组鼻窦的炎症发生和加重。
Objective: To provide surgical anatomy basis for the clinical operation of endoscopic sinus surgery. Methods: Gastric bubble development was observed on 40 adult cadaver heads treated with anticorrosion treatment on 40 sides. The drainage of the frontal sinus and the anterior chamber was observed. Results: The frontal sinus accounted for 87.5% (3 5 sides) of the middle nasal passages, 10.0% (4 sides) to the funnel, 90.0% (36 sides) of the middle nasal passages, To the funnel drainage diverticulum accounted for 10.0% (4 sides); frontal recess to the middle nasal drainage accounted for 15.0% (6 sides); to the funnel drainage accounted for 10.0% (4 sides); to the lateral sinus drainage Accounting for 75% (30 sides). Sieve bubbles diverted to the screen funnel accounted for 25.0% (10 sides), and lateral sinus drainage accounted for 75.0% (30 sides). CONCLUSION: Anatomy of the uncinate process and the mesial bubble directly affect the ventilation and drainage of the anterior sinuses, resulting in inflammation and aggravation of the anterior sinuses.
