Recently, we described three components of a normal pharyngeal swallowing sound. The aim of the present study was to identify variations of these components using synchronized acoustic-radiological data in partially laryngectomized (PL) and totally laryngectomized (TL) patients before and after surgery. In this prospective study, from January 2003 to December 2006 we enrolled 14 patients in a PL group and 9 patients in a TL group. A fluoroscopy camera and a microphone were connected to a computer to obtain acoustic-radiological data (25 images/s). The subjects were asked to perform six deglutitions of 10 ml of barium suspension. The average durations of the sound variables were measured before and after surgery. The duration of the preoperative pharyngeal sound was 602 ms in the PL group and 562 ms in the TL group. It was significantly decreased after the TL (296 ms) and was increased after the PL (740 ms). A typical profile of the swallowing sound for each group was obtained. This study allowed us to describe the main variations of the pharyngeal swallowing sound induced by PL and TL. This noninvasive tool could be useful to assess postoperative swallowing function.

To investigate the characteristics of respiratory-swallow coordination (RSC) in poststroke dysphagia (PSD) patients following infratentorial stroke (IS) and further explore their association with aspiration. PSD patients after IS and age-matched healthy controls were recruited. Nasal airflow and sound signals were recorded using a nasal cannula-type flow sensor and contact microphone, which were synchronized with videofluoroscopic swallowing studies (VFSS).

Objective: Haji et al. reported that characteristic click-like sounds during the swallowing reflex were recorded with a small lavalier microphone placed in the ear. They also reported that endoscopic and phototubometric observations showed that these sounds were likely related to the opening and closing of the Eustachian tube during swallowing.

Statement Of Problem: Studies on the significance of intensity on speech production with a tongue prosthesis are lacking, despite this being an important criterion in speech production in patients with total glossectomy.
Purpose: The purpose of this cross-over clinical study was to assess acoustic signal intensity and frequency in patients with total glossectomy rehabilitated with mandibular dentures with 2 different attachment designs for the tongue prosthesis.
Material And Methods: Seven participants initially received a mandibular denture with a tongue prosthesis attached using an acrylic resin plate.
