下鼻甲神经分布研究

目的：通过尸头解剖明确下鼻甲神经分布情况，为选择性切断支配下鼻甲神经治疗变应性鼻炎提供解剖基础。方法：4％多聚甲醛固定成人尸头标本20例（40侧），从正中矢状位锯开，在10倍手术显微镜下解剖下鼻甲。结果：①鼻后下神经在黏膜和骨膜之间下行由下鼻甲附着处末端前方6～13mm处进入下鼻甲黏膜下，另有分支通过下鼻甲附着处末端进入下鼻甲黏膜下。②筛前神经在下鼻甲附着处上缘距前端2．0～4．6mm进入下鼻甲黏膜下。结论：鼻内镜下选择性地切断支配下鼻甲的神经支配是可行的。

The distribution of nerves in inferior turbinate

OBJECTIVE: The distribution of nerve in inferior turbinate was observed to provide anatomy evidence for inferior turbinate surgery by measuring and dissecting corpses. METHOD: Inferior turbinate was dissected under the microscope in 20 heads of corpses. RESULT: (1) The posterior inferior nasal nerve marched down between the mucosa and the periosteum, and entered the inferior turbinate at the site 6 to approximately 13 mm before the end of inferior turbinate. (2) The antierethmoid nerve went to the inferior turbinate 2.0 to approximately 4.6 mm behind the beginning of the inferior turbinate. CONCLUSION: Selective cut of the nerves of the inferior turbinate under the nasal endoscope is feasible.
