Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

Identification and preservation of internal carotid artery during endoscopic nasopharyngectomy in cases of malignancy is a main difficulty of this kind of surgery, especially when anatomy is distorted by previous radiation. Intraoperative navigation based on preoperative imaging cannot remain precise throughout the process of resection. We aim to check a feasibility of internal carotid artery localization with the help of transnasal ultrasonic scanning. The most appropriate for this method existing device is an echocardiography system with pediatric transesophageal transducer.

We plan to use it in 20 patients undergoing elective surgery for inflammatory sino-nasal disease. After initiatioin of general anesthesia and local decongestion, transducer will be placed transnasally to nasopharynx in order to scan a parapharyngeal space.
