Clinical value of preoperative intraoral ultrasonography in tonsillectomy.

In this prospective study, 43 chronic tonsillitis patients underwent intraoral ultrasonography preoperatively and the width and thickness of tonsils and tonsillocarotid distances were measured. Positive correlation was obtained in postoperative measurements compared with ultrasonographic measurements of tonsils. The mean tonsillocarotid distances were 8.6 mm in the left and 8.25 mm in the right tonsillar fossa. This study showed that preoperative intraoral ultrasonography was to be help of tonsillectomy operations particularly in surgical anatomical orientation.
