definition of a voice disorder
individual’s quality pitch or loudness is different from those in similar demographics.
etiologies of a voice disorder
structural, medical, neurologic, psychological
a voice disorder is from predisposing presipitating (inciting) and
perpetuating factors
factors that influence the prevalence of voice disorders
age, gender, occupation
the largest epidemiology study of voice disorders showed 7% of adults (aged 21-66) reported a
“current” voice disorder
the largest epidemiology study of voice disorders showed 30% of adults reported a
voice disorder at some point during their “lifetime”.
CHRONIC voice disorders are more common among men or women
womenchro
age of common individuals with CHRONIC voice disorders
40-59 years
CHRONIC voice disorders are more common among a history of
heavy voice demands, reflux symptoms, chem exposures, frequent upper respiratory infections
structural pathologies, inflammatory conditions, trauma or injury,
systemic conditions affecting voice,
aerodigestive conditions affecting voice,
psychiatric or psychological disorders affecting voice,
neurological voice disorders,
“other” disorders of voice
are all what the
classification manual for voice disorders-1 organizes pathologies into eight major groups.
any alteration in the histological structure of the vocal fold are.
structural pathologies of the vf
changes in the layered structure of the vocal fold may affect the
mass
size
stiffness
flexibility
tension of the vibrating mechanism
changes in the layered structure of the vf may alter voice
quality, pitch, and loudness
voice quality varies in patients with structural pathology and often reflects.
lesion severity
pts habitual voice use patterns
presence/absense of compensatory adustments?
lesion severity refers to the
size and site of lesion and the depth of invasion into the deeper layers of the vf
compensatory adjustments: adaptive changes including improved breath support, enhanced v/t tuning, appropriate changes in pitch and loudness, refers to which compensatory adjustment?
productive
compensatory adjustments: extreme muscle activation/effort, poor tone focus, inappropriate changes in pitch & loudness refers to which compensatory adustment?
maladaptive compensatory strategies.
malignant lesions include
laryngeal carcinoma.
typically quamous cell type originating from the epithelium is
laryngeal carcinoma.
as a tmr progressess it invades the deeper layers of the vd including the
vocalis muscle.
for malignant lesions dysphonia severity varies according to
location and extent of tumr invasion.
risk factors for laryngeal carcinoma
smoking, alcholo use ? laryopharyngeal reflux
once biopsy confirms defenitive diagnosis of ca, treatment typically involves…
radiation, chemo, surgical excision (depends on size, extent, and type of malignancy) or a combination approach
benign epithelial and lamina propria abnormalities of the vf disagreement
how to classify various lesions of the superficial layers of the vds.
