- Abstract:
- By comparing CT scans of the larynx with anatomical sections in the horizontal plane as well as by examining patients, a method of investigation especially aimed at phoniatric questions has been worked out: CT scans are performed every 4 mm parallel to the vocal cord plane using a center of 50 HE and a window of 350 HE. The examination is done during regular respiration and if required can also be performed during phonation when producing the vowel /u/. Using this technique the laryngeal structures of clinical relevance can be demonstrated with the help of at least 10 scans. It requires little time and the radiation exposure for the patient is minimal. The accuracy of CT measurements corresponds excellently to the anatomical features. Allowing an exact evaluation of anomalies of the larynx in shape and position, CT essentially improves phoniatric diagnostics.
