作者采用颞骨解剖和 CT 扫描详细叙述了单孔的结构及其毗邻关系。本文对20例颞骨解剖的测量结果和21例正常 CT 图像及8例经乙状窦后进路内听道前庭神经切除术患者术前 CT图像的测量结果进行了分析比较,经 t 值检验,两者差别不显著(P>0.10),仅 CT 图像上单孔弯曲段在颞骨内重叠,使其长度较实际长度短(P<0.05)。单孔为支配后半规管壶腹的后壶腹神经通过颞骨的通道,其长约4.5mm,
The authors describe the structure of single-hole and its adjacency in detail using temporal bone anatomy and CT scanning. In this paper, 20 cases of temporal bone anatomical measurements and 21 cases of normal CT images and 8 cases of retrograde sinus approach to the posterior tibial nerve resection in patients with preoperative CT images were analyzed and compared the results of the t-test, two (P> 0.10). Only the single-hole curved sections of CT images overlap in the temporal bone, making the length shorter than the actual length (P <0.05). A single hole to dominate the posterior semicircular canal ampulla posterior ampulla nerve passage through the temporal bone, which is about 4.5mm long,
