The parapharyngeal internal carotid artery (ppICA) lacks reliable landmarks from an endonasal perspective, making surgery in this region challenging. This video presents the clinical application of the transpterygoid-transmandibular strut-transmedial jugular tubercle inferior transpetrosal endoscopic endonasal approach as a roadmap to the ppICA. It concerns a case of nasopharyngeal carcinoma of the right Rosenmuller fossa whose resection entailed exposure of the paraclival and petrous carotid artery, which subsequently enabled safe dissection of the ppICA.
