摘要
目的:为上颌窦和额窦冲洗及内窥镜术提供解剖学基础。方法:作者对60侧成人尸体头部正中矢状切面标本进行解剖,观测了中鼻道、额隐窝、额鼻峡(管)、上颌窦口、半月裂孔的形态、大小、位置、及上颌窦口和额鼻管口的角度及与周围结构的关系。结果:上颌窦口内径3.0±0.2mm,距鼻小柱前下缘46.0±4.0mm,鼻小柱至上颌窦口与鼻腔底平面之间的夹角为38.4±6.2°,鼻额管外口(额鼻峡)内径2.8±0.3mm,距鼻小柱前下缘47.9±3.4mm,鼻小柱至额鼻管外口与鼻腔底平面之间的夹角为56.7±7.3°。结论:经窦口行额窦及上颌窦冲洗及功能性鼻内窥镜术时应注意额鼻管、上颌窦口的位置、角度及毗邻关系。
Objective: To provide anatomy basis for the irrigation and endoscopy of the sinus maxillaris and frontalis. Methods: The middle nasal meatus, apertura of sinus maxillaris, frontalis and hiatus semilunar were disseced and observed on 60 side specimens of midian sagittal section of adult head. Results: The internal diameter of apertura sinus maxillaris and to nasal floor is 38.4 ± 6.2°. The internal diameter of inferior orifice of frontal nasul tube is 2.8 ± 0. 3mm. The distance from nasal rod to orifice of fromtal nasul tube is 47.9 ± 3 . 4mm. The angle between nasal rod to orifice frontal nasal tube and to nasl floor is 56.0 ± 7.3°. Conclusion: Special attention should be paid to the position and angle of the apertura sinus maxilleris and frontal nasal tube during the epdoscopy and irrigating of maxillary sinus and frontal sinus from sinus apertura.
