what is ADMET?

aerodynamic myoelastic theory of phonation (pg.348)

what are the 5 mechanisms involved in one cycle of glottal vibration that results in vocal fold vibration in ADMET

1. the adductor muscles (LCA and IA) close the vocal folds while the tenors (CT and TA) stiffen the vocal folds to the desired fundamental frequency 2. as person begins to exhale, sub glottal pressure builds beneath the vocal folds. pressure builds until it is great enough to overcome the resistance of the vocal fold and push the folds open 3. a glottal pulse is released creating an acoustic shock wave traveling through the vocal folds 4. once the folds have been blown open forces of the elastic recoil and the bernoulli effect help to bring the folds back to there original position 5. the opening and closing of the vocal folds during phonation is the result of the aerodynamic and muscular foyers indicated above (pg. 348-349)

what does the cover-body theory of vocal fold vibration state?

- the vocal fold cover moves independently of the body - the TA muscle (body) participates very little in vibratory movement - movement of the vocal ligament falls in between the significant movement of the cover and the minimal movement of the body - this theory suggests that anything that interferes with the movement of the cover will affect the resulting voice quality (pg. 349)

a. vocal nodule (pg.349)

a. vocal nodule b. polyps c. polypoid degeneration - phonotrauma resulting in hyper functional vocal fold adduction results in would formation arising in the superficial layer of the lamina propria - polyps may result from periods of phonotrauma or from a single traumatic accident

b. polyps (pg.350)

treatment a. muscle tension dysphonia b. psychogenic dysphonia c. puberphonia d. ventricular phonation - symptomatic voice therapy is the treatment of choice - good evidence exists for benefit received from circumlaryngeal massage - GERD should be managed and good vocal hygiene behaviors followed - in some cases BOTOX injections have been found to successfully break the cycle of chronic, unnecessary, excessive vocal tension

a. muscle tension dysphonia (pg.351)

treatment a. muscle tension dysphonia b. psychogenic dysphonia c. puberphonia d. ventricular phonation - symptomatic voice treatment focusing on establishing and then extending a vocal tone is the treatment of choice - evidence supports the use of circumlaryngeal massage - referral to a professional to help the patient understand and deal with underlying psychological issues can be appropriate - typically, once voice is reestablished and patients understands that they are in control of their voice, no further loss of voice occurs or it is short lived

b. psychogenic dysphonia (pg.352)

treatment a. muscle tension dysphonia b. psychogenic dysphonia c. puberphonia d. ventricular phonation - voice therapy focusing on the production and then the establishment of a normal, lower pitch in a hierarchy from a single sound to conversation is the treatment of choice - treatment approaches may involve circumlaryngeal massage and/or hard glottal attacks - initially, patients may have difficulty using the voice with family and friends and may not identify with the normal, low voice as their own, but with continued use of the normal voice and with support, the transition to habitual use does occur

c. puberphonia (pg.352)

treatment a. muscle tension dysphonia b. psychogenic dysphonia c. puberphonia d. ventricular phonation - symptomatic voice therapy is the treatment of choice when normal true vocal fold function is present - initial establishment of tone produced by the true folds is key and if so produced, this tone is extended through a hierarchy of lengthening productions

a. vocal cord dysfunction (pg.352)

characteristics a. vocal cord dysfunction b. inferior (recurrent) laryngeal nerve paralysis c. superior laryngeal nerve paralysis d. spasmodic dysphonia - damage to the nerve results in the affected vocal fold typically rising in the paramedian position just lateral to midline - the thyroarytenoid muscle fibers atrophy from lack of neruostimulation - voice can be breathy and soft and patients typically have a weak cough - maximum phonation time is decreased - under strobe, the vocal folds will vibrate asymmetrically and aperiodically

b. inferior (recurrent) laryngeal nerve paralysis (pg. 353)

characteristics a. vocal cord dysfunction b. inferior (recurrent) laryngeal nerve paralysis c. superior laryngeal nerve paralysis d. spasmodic dysphonia - if the internal branch is affected then sensation to the glottal and sub glottal area region is compromised - unilateral damage to the external branch affects only the cricothyroid muscle - this causes an inability to lengthen the muscle on that side and results in altered pitch control and reduced pitch range - may complain of vocal fatigue

a. maximum phonation time b. airflow rate c. estimates of subglottic pressure d. laryngeal airway resistance -estimate of glottal valving efficiency

b. airflow rate (pg.357)

a. maximum phonation time b. airflow rate c. estimates of subglottic pressure d. laryngeal airway resistance -estimates are made in reference to oral pressure determined just following release of the bilabial voiceless plosive /p/ using a mask integrated with special sensors

c. estimates of sub glottal pressure (pg.357)

a. maximum phonation time b. airflow rate c. estimates of subglottic pressure d. laryngeal airway resistance - the ratio of air pressure to the flow of air through the glottis - measured in H2O per cc per second

d. laryngeal airway resistance (pg.357)

what features are assessed during laryngolic/ stroboscopic assessment?

1. glottal closure 2. symmetry of movement 3. periodicity 4. amplitude of movement 5. movement of the mucosal wave (pg. 357)

what are 4 additional areas that should be assessed during a voice evaluation?

1. resonance 2. tremor 3. motor speech production 4. intelligibility (pg. 357)

what are 5 guidelines for good vocal health?

1. rare or minimal use of loud, effortful voice 2. attention to potential larygo-pharyngeal reflux 3. reducing unnecessary coughing and throat-clearing 4. adequate hydration 5. holistic elements: good nutrition, enough rest, regular physical exercise, good mental health (pg. 358)

a. resonant voice therapy b. botox c. vocal function exercise -focuses on optimizing voice quality through a focus on maximizing oral-pharyngeal resonance and the degree of medial compression between the vocal folds

a. resonant voice therapy (pg.358)

a. resonant voice therapy b. botox c. vocal function exercise -injection into thyroarytenoid or other intrinsic muscles for treatment of spasmodic dysphonia and sometimes essential tremor of the voice

b. botox (pg.358)
