We previously developed an instrument called the Aerodynamic Vocal Fold Driver (AVFD) for intraoperative magnified assessment of vocal fold (VF) vibration during microlaryngoscopy under general anesthesia. Excised larynx testing showed that the AVFD could provide useful information about the vibratory characteristics of each VF independently. The present investigation expands those findings by testing new iterations of the AVFD during microlaryngoscopy in the canine model.

Name: The Laryngoscope
Vibration of the vocal folds can disrupt the tissue and induce structural, functional, and molecular changes; the presence or absence of contact between the vocal folds during vibration can affect the...
Purpose This study investigated whether metabolic respiratory requirements (treadmill workload) affected glottal valving in phonation, based on aerodynamic measures, when a sound pressure level (vocal...
To investigate the role of laryngopharyngeal reflux (LPR) in the development of benign lesions of the vocal folds (BLVF).
A well-recognized cause of dyspnea in athletes is vocal cord dysfunction (VCD). VCD is characterized by paradoxical vocal fold movement (PVFM) in which the vocal folds adduct (close) during inspiratio...
An increasing number of vocal fold cysts excised, as compared to polyps, over the last decade led us to review these cases. We found a statistically significant increase in cysts excised as compared t...
The proposed research will investigate the most effective strategy to reduce vocal exertion reported by speakers in noisy environments. Repeated vocal exertion can lead to voice problems a...
The aim of this clinical trial is to provide information about autofluorescence of pathological versus healthy vocal folds tissues. Experimentations are performed on vocal folds biopsies ...
simple combination of functional investigation, in form of laryngostroboscopy, together with conventional histopathological examination, provides a highly sensitive method in differential ...
This phase I single center open labeled study is planned to assess the safety and tolerability of bevacizumab for treating patients with bilateral RRP. Approximately 20 patients will recei...
This research aims to evaluate the effects of vocal conditioning through two semioccluded vocal tract exercises (SOVTE) in choir singers.
The process of producing vocal sounds by means of VOCAL CORDS vibrating in an expiratory blast of air.
The vocal apparatus of the larynx, situated in the middle section of the larynx. Glottis consists of the VOCAL FOLDS and an opening (rima glottidis) between the folds.
A disorder in which the adductor muscles of the VOCAL CORDS exhibit increased activity leading to laryngeal spasm. Laryngismus causes closure of the VOCAL FOLDS and airflow obstruction during inspiration.
Measurement of parameters of the speech product such as vocal tone, loudness, pitch, voice quality, articulation, resonance, phonation, phonetic structure and prosody.
A pair of cone-shaped elastic mucous membrane projecting from the laryngeal wall and forming a narrow slit between them. Each contains a thickened free edge (vocal ligament) extending from the THYROID CARTILAGE to the ARYTENOID CARTILAGE, and a VOCAL MUSCLE that shortens or relaxes the vocal cord to control sound production.
An anesthesiologist (US English) or anaesthetist (British English) is a physician trained in anesthesia and perioperative medicine. Anesthesiologists are physicians who provide medical care to patients in a wide variety of (usually acute) situations. ...
Anesthesia is the loss of feeling or sensation in all or part of the body. It may result from damage to nerves or can be induced by an anesthetist (a medical professional) using anesthetics such as thiopental or propofol or sevoflurane during a surgical ...
