Document Summary
Changes in vocal fold tissue: misuse (not abuse) Vocal polyps: small fliud-filled sacs: blister-like, persistent vocal misuse. Treatment: rest, changes in voice use. Laryngeal papilloma: wart-like growth: hoarse voice, sounds like a whisper, caused by human papilloma virus (hpv, laser surgery. Laryngeal cancer: cancer in the larynx, speech options: Alaryngeal speech: use air flow from esophagus to articulate words. Electrolarynx: a handheld device held to the neck, creates vibrations that helps the person speak. Silent speech interfaces (emg-based silent speech recognition) Vocal fold paralysis: central nervous system, peripheral nervous system. Spasmodic dysphonia: squeezing vocal output, strained/strangled, botox injection for treatment, not a cure. Phase one: oral preparatory: bolus: chewed up food. Phase two: oral transport: moving the tongue so that bolus moves back to the throat. Phase three: pharyngeal: close the nasal pathway, epiglottis channels food, close vocal folds, aspiration, aspiration pneumonia, silent aspiration. Phase four: esophageal: reflux, gerd (gastroesophageal reflux disease)
