Abstract: In recent years, the lesions of the pterygopalatine fossa and the carotid artery are treated with transnasal endoscopic approaches in foreign countries gradually. The anatomy of the pterygopalatine fossa and its canals, such as palatovaginal canal and vidian canal, have been studied thoroughly. However, literatures about the anatomy and clinical applied anatomy of the petrous apex, internal carotid artery,c livus and cranio-vertebral junction space were reported rarely in China. The main causes to cast negative influence on the endoscopic skull base surgery are the complicated structures, anatomical variations and lack of reliable anatomical landmarks. Disorientation of the surgical field is the major risk faced by otorhinolaryngologists and neurosurgeons during endoscopic surgery.

Key words: Vidian canal, Internal carotid artery, Endoscopy, Surgery, Petrous segment, Palatovaginal canal, Otolaryngology
