目的 :通过研究鼻中隔各部厚度的变化及其与周围结构的关系 ,为临床涉及鼻中隔的疾病的诊断和治疗提供解剖学依据。方法 :采用 18具成人头部连续冠状和横断层标本 ,观测鼻中隔及其邻近结构。结果 :鼻中隔各部厚度不一 ,鼻中隔前 1/3的中段最厚 ,达 10 8± 1 2mm ;后部较薄处仅为 1 5± 0 3mm。增厚的部分以粘膜为主 ,达 8 6± 0 7mm。结论 :在行鼻中隔偏斜纠正术、判断鼻腔出血的部位及寻找鼻腔通气障碍的原因时 ,均应考虑鼻中膈增厚的因素
OBJECTIVE: To provide anatomic evidences for the diagnosis and treatment of diseases involving the nasal septum by studying the changes of the thickness of the nasal septum and its relationship with the surrounding structures. Methods: A total of 18 consecutive adult coronal and transverse cranial heads were used to observe the nasal septum and its adjacent structures. Results: The thickness of nasal septum was different. The middle 1/3 of the nasal septum was the thickest, reaching 108 ± 122 mm. The posterior thinner was only 150 ± 0 3 mm. Thickened part of the mucosa, up to 86 ± 0 7mm. CONCLUSIONS: In the correction of nasal septum deviation, the location of nasal bleeding, and the reasons for finding nasal ventilation disorders, the factors of thickened nasal septum should be considered
