摘要
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20具40侧经防腐处理的完整成人尸头标本上,观测鼻腔外侧壁诸结构的大小、分别与鼻前棘距离及其连线与鼻底平面之夹角。结果:上鼻甲长度为15.9±2.9mm,宽度为4.7±1.1mm;中鼻甲长度为36.5±3.4mm,宽度为10.4±3.4mm;下鼻甲长度为42.7±3.6mm,宽度为12.3±1.7mm。鼻前棘至中鼻甲前下端、后下端、额窦开口、蝶窦开口连线的距离及其与鼻底夹角分别为34.0±3.5mm、51.7±4.6mm、49.3±4.3mm、54.5±4.0mm及73.2±6.4°、22.8±3.3°、78.5±8.3°、43.5±5.2°。结论:鼻前棘至中鼻甲前下端、后下端、额窦开口、蝶窦开口连线距离及其与鼻底夹角的测量,为临床在内窥镜下寻找窦口、探入窦口及保护中鼻甲提供了解剖学依据。
Objective:To provide surgical anatomy basis of the lateral nasal wall for endoscopic sinus surgery. Methods:The lateral nasal wall was observed on 20 adult cadavers's specimens. Results: The length of superior nosepiece was 15.9 ± 2. 9mm, the length of middle nosepiece was 36.5 ± 3. 4mm, the length of lower nosepiece was 42.7 ± 3. 6mm, The distance from the fore - lower - end of middle nosepiece to the nasal spine was 34.0 ±3.5mm, the distance from the back - lower - end of niddle nosepiece to the nasal spine was 51.7 ± 4. 6mm. The distance from the ostium of frontal sinus to the nasal spine was 49.3 ± 4. 3mm, the distance from the ostium of sphenoid sinus to the nasal spine was 54.5 ± 4.0mm. The angle between line from the fore - lower - end of middle nosepiece to the nasal spine with nasal bottom was 73. 2 ± 6. 4°, The angle between line from the back - lower - end of middle nosepiece to the nasal spine with nasal bottom was 22.8 ±3.3°,The angle between line from the ostium of frontal sinus to the nasal spine with nasal bottom was 78. 5 ± 8. 3°,The angle between line from the ostium of sphenoid sinus to the nasal spine with nasal bottom was 43. 5 ± 5.2°. Conclusion:The distance and angle between line from the fore - lower - end of middle nosepiece, the back - lower - end of middle nosepiece, the ostium of frontal sinus, the ostium of sphenoid sinus to the nasal spine provided reference looking for and exploring the ostium of frontal sinus and sphenoid sinus and protecting middle nosepiece.
