腮腺周围间隙的断层解剖学及临床意义

Sectional anatomy and clinical significance of the periparotid space

目的 为腮腺周围间隙疾病的影像诊断提供解剖学基础。方法 选用成年尸体头颈部 6 0例 ,分别作冠状、矢状和横断层解剖。在三维断面上观察腮腺周围间隙的解剖学关系、围成、内容及其交通 ,测量腮腺周围间隙的面积及间隙周围重要结构的面积和宽度。结果 两侧腮腺周围间隙及间隙周围重要结构呈对称性 ,面积及宽度差异均无显著性 (P >0 0 5 )。冠状、矢状和横断面是分别显示腮腺周围间隙、颊间隙和腮腺间隙的最佳断层解剖。腮腺周围间隙可直接相通或借结缔组织和通行于间隙中的神经、血管间接相通。翼内肌、翼外肌、茎突、颈内动脉和颈内静脉是MRI等断层影像诊断的重要解剖学标志。结论 腮腺周围间隙的断层解剖对腮腺周围间隙疾病的影像诊断具有重要意义。

Objective To provide anatomical basis for imaging diagnosis of the periparotid space diseases. Methods Sixty headneck of adult corpses were selected and cut into coronal, sagittal and transverse section respectively. At the three dimensional section, Relationship,boundary, content and channel of the periparotid space were observed. It were measured that the periparotid space in area and important structures of related space in area and width. Results Periparotid space and important structures were symmetrical of both sides, There were no significant differences in the area and width( P >0.05).It was better to show periparotid, buccal and parotid space with coronal,sagittal and transverse section separately. Periparotid space were connected directly or indirectly by connective tissue and nerve,vessel through the space. Medial pterygoid, lateral pterygoid, styloid process, internal carotid artery and internal jugular vein were important anatomical marks for sectional imaging of MR. Conclusion Sectional anatomy of the periparotid space has an important significance for imaging diagnosis of the periparotid space diseases.
