title: Feasibility of using computerized tomography in diagnosing nasopharyngeal closure.
abstract: The feasibility of using computerized tomography for diagnosing nasopharyngeal anatomy and physiology was investigated. Ten adult subjects with normal communication were assessed with an Ohio-Nuclear Delta Scan 2020 Whole Body Computed Tomographic Scanner at two different levels of the nasopharynx during rest and production of /u/ and /s/. Lateral and anterior-posterior dimensions of the pharynx were simultaneously x-rayed and computed for each subject and condition. Computerized tomography appears to be useful in directly mapping the nasopharynx and in providing precise three-dimensional configurations without using a contrast medium.
