Vidian canal as a landmark to endoscopic nasal skull base surgery / 中国耳鼻咽喉头颈外科

OBJECTIVE To analyze whether the vidian canal can be served as a landmark to endoscopic nasal skull base surgery and provide clinical reference by imaging and anatomical methods. METHODS Twenty three cadaveric heads were scanned through axial and coronal high resolution CT to observe the vidian canal and its relationship with around structures.Three cadaveric heads, in which arteries were injected with latex,were dissected by endoscopic transnasal or transmaxillary to pterygopalatine fossa and cavernous sinus approaches.RESULTS 1.The course and shape of vidian canal and its relationship with around structures can be clearly detected through high resolution CT.All the vidian canals were on the same level or below the internal carotid canal.2.Anatomic study corresponded to the results of imaging.Vidian content pointed to the anterior genu of internal carotid artery constantly.The vidian canal and foramen rotundum can serve as a surgical corridor.CONCLUSION As the landmark, vidian canal plays an important role in the endoscopic nasal skull base surgery.Being a bony canal,it can be detected through high resolution CT easily and clearly.
