Computer Modeling of Pharyngoesophageal Segment during Tracheoesophageal Phonation Using Finite Element Acoustic Models with Preliminary Validation

چکیده
Introduction and aim: Total laryngectomy surgery is performed in patients with large or recurrent laryngeal cancer. Following removal of the larynx, tracheoesophageal (TE) voice is the gold standard for achieving phonation. The mechanisms underlying TE voice are not fully understood, but pharyngoesophageal (PE) segment vibration has been shown to play a key role [1]-[3]. The aim of this study was to systematically explore the mechanics of PE segment vibration during TE phonation.

Background: rehabilitation of individuals with total laryngectomy. Aim: to correlate the voice and speech proficiency of individuals with total laryngectomy, users of tracheoesophageal, prosthesis with the intraluminal pharyngoesophageal transition pressure at rest and during phonation. Method: twelve individuals with total laryngectomy and with tracheoesophageal voice, users of speech prosthes...

To estimate joint loads via musculoskelet...
متن کاملA new proposal for evaluation of the pharyngoesophageal segment and its relation with the narrow-band spectrogram in tracheoesophageal speakers.
PURPOSE The primary purpose of this study was to assess the relationship between pharyngoesophageal segment (PES) configuration and narrow-band spectrogram of tracheoesophageal voices. METHODS This study included 30 total laryngectomees tracheoesophageal speakers. Patients were assessed by videofluoroscopy (VF), during deglutition and voicing, and the vowel /a/ was recorded for spectrographic...
متن کاملRelation between the dimensions and intraluminal pressure of the pharyngoesophageal segment and tracheoesophageal voice and speech proficiency.
BACKGROUND The objective of the present study was to relate the dimensions and the intraluminal pressure of the pharyngoesophageal segment (PES) to the voice and speech proficiency of total laryngectomees with a tracheoesophageal prosthesis (TEP). METHODS Twenty total laryngectomees with secondary TEP insertion underwent evaluation of voice and speech, manometry, and videofluoroscopy. RESUL...
متن کاملThe role of videofluoroscopy and ultrasound in assessing pharyngoesophageal muscle tone after laryngectomy.
The aim of this study was to compare the respective value of videofluoroscopy and ultrasound for assessment of the tonicity of the neoglottis and determination of the exact neolaryngeal segment of hypertonicity. We examined twelve patients who had developed inadequate tracheoesophageal voice following total laryngectomy and installation of tracheoesophageal prosthesis. We assumed that the cause...
