Abstract
A new integrated videoendoscopic/photodetection system, including an endoscope with an internal instrument channel used for photodetection, was applied to the evaluation of velopharyngeal closure in a subject with marginal velopharyngeal insufficiency (VPI) and in a subject with no speech disorder. Acoustic and aerodynamic speech assessments were used to establish the severity of velopharyngeal impairment in the marginal VPI patient. A light-out condition was used to establish the photodetector criterion for closure. The new system was effective for providing detailed phonetic assessment of velopharyngeal closure. Variations in degree of closure during select oral and nasal consonant productions were identified in the VPI subject but not in the normal speaking subject. The data show that important details of velopharyngeal insufficiency can be identified using the integrated endoscopic/photodetection system.
