摘要：
Objective Anatomic knowledge is needed to avoid injury to internal carotid artery (ICA) during the endoscopic surgery around nasopharynx and its surrounding space. Design We prospectively studied the computed tomography angiography (CTA) data of 28 patients with image processing software. Special attention was given to ICA and various landmarks around nasopharynx. Results The anatomic relationship between ICA and different landmarks around nasopharynx was clearly presented in three-dimension. The fossa of Rosenmuller is the nearest point of the nasopharyngeal cavity to ICA. The opening of the Vidian canal in the middle cranial fossa could be either above, below, or at the level of the horizontal segment of petrous ICA. The pharyngeal trunk of the ascending pharyngeal artery can also be clearly identified in most reconstructed CTA images. Multiple anatomic relationships were also quantified. Conclusions Reconstructed CTA can provide key anatomic information for a safe and accurate endoscopic dissection around nasopharynx.
