Sectional anatomy and dissection allow topographic study of the peripharyngeal region. Anatomic study has been performed by projection on the skull base of the limiting fascia and by 6 mm thick anatomic slices in the three fundamental planes. Three spaces are identified: retropharyngeal space represents a slipping structure upon the cervical spine. The prestylian space is mostly formed by an adipose column along the pharynx and by the medial part of the parotid gland. The retrosylian space includes the internal jugular and carotid vessels, the four last cranial nerves and the cervical part of the laterovertebral sympathetic trunk. CT an MR imaging were performed on ten patients with cervical or cephalic diseases distant from peripharyngeal regions. CT imaging is only useful in axial and frontal views for the prestylian space. MR imaging is the best method to visualize the three components of the peripharyngeal region. Confronting sectional imaging with anatomic slices allows better recognizing of limits and contents of the different parts of peripharyngeal regions.
断层解剖学和解剖术有助于对头颈周围区域进行局部研究。通过在颅底投影限制筋膜以及在三个基本平面制作6毫米厚的解剖切片来进行解剖学研究。确定了三个间隙：咽后间隙是颈椎上的一个滑动结构。茎突前间隙主要由沿咽的脂肪柱和腮腺内侧部分构成。茎突后间隙包括颈内静脉和颈动脉、最后四对脑神经以及外侧椎动脉交感干的颈部部分。对十名患有远离头颈周围区域的颈部或头部疾病的患者进行了CT和MR成像检查。CT成像仅在轴位和额位视图中对茎突前间隙有用。MR成像是可视化头颈周围区域三个组成部分的最佳方法。将断层成像与解剖切片相对照，有助于更好地识别头颈周围区域不同部分的界限和内容物。
