Switching of the Laryngeal Cavity From the Respiratory Diverticulum to the Vestibular Recess: A Study Using Serial Sagittal Sections of Human Embryos and Fetuses
Journal of Voice (2016) Vol. 30, No. 3, pp. 263-271

A cecum-like protrusion of the pharynx (the laryngeal cecum or vestibular recess [VR]) develops immediately anterior to the laryngeal part of the respiratory diverticulum. An expansion of the VR has been well described, whereas the fate of the diverticulum is ...

Humans are the most complex singers in nature, and the human voice is thought by many to be the most beautiful musical instrument. Aside from spoken language, singing represents a second mode of acoustic communication in humans. The purpose of ...

The Low Mandible Maneuver and Its Resonential Implications for Elite Singers
Journal of Voice (2016) Vol. 30, No. 1, pp. 128.e13-128.e32

Many elite singers appear to frequently drop the posterior mandible while singing to optimize resonance production. This study investigated the physiology of the Low Mandible Maneuver (LMM) through the use of magnetic resonance imaging (MRI), ultrasound (US), and spectrographic analysis. ...

Homeostasis of Hyaluronic Acid in Normal and Scarred Vocal Folds
Journal of Voice (2015) Vol. 29, No. 2, pp. 133-139

Vocal fold scarring is one of the most challenging laryngeal disorders to treat. Hyaluronic acid (HA) is the main component of lamina propria, and it plays an important role in proper vocal fold vibration and is also thought to be ...

The Effect of Stretch-and-Flow Voice Therapy on Measures of Vocal Function and Handicap
Journal of Voice (2015) Vol. 29, No. 2, pp. 191-199

Objectives: To investigate the efficacy of stretch-and-flow voice therapy as a primary physiological treatment for patients with hyperfunctional voice disorders. Study Design: Prospective case series. Participants with a diagnosis of primary muscle tension dysphonia or phonotraumatic lesions due to hyperfunctional ...
