Vocal Misuse
|
- Reduces phonatory mechanisms ability to work efficiently
- Disrupts coordination of parts |
|
Puberphonia
|
A.K.A.
Adolescent falsetto, Pubescent falsetto, Incomplete mutation, Mutational falsetto - Persistent high pitched voice beyond the age at which the male voice change should have occured |
|
Vocal Misuse
|
-Inappropriate pitch (puberphonia, glottal fry, lack of pitch variability
-Excessive talking (aphonia, dysphonia, ventricular phonation) - Increase tension and strain (hard glottal attack, high laryngeal position) |
|
Benign lesion
|
Symptom: Hoarseness
Epithelial lesions Abnormal tissue growth Examples: leukoplakia, hyperkaratosis (smoking), papillary keratosis (wart like precancer) |
|
Trauma
|
Causes: attempted strangulation, fracture, surgical reconstruction
|
|
Web
|
Fusing of vocal tissue, almost like a scab from scar tissue
|
|
Ventricular phonation
|
- Misuse
- the false vocal folds have bulked up over true vocal folds b/c of bulky vocal folds Symptoms: normal symmetry, reduced amplitude, reduced mucosal wave |
|
Edema
|
-Fluid- like buildup retention, swelling related to abuse and smoking
Location: Reinkes space (superficial), bliateral - greater muscosal wave because of increased mass, decrease stiffness Tx: - change diet to lower acid - hydrate - voice rest Pachedema- posterior laryngeal swelling |
|
Acoustics of Edema
|
Increased mass=
- lower fundamental frequency - increased spectral noise - increase amplitude variability |
|
Intracordal Cysts
|
2 Types:
1)retention cyst (hard mucous) 2) epidermoid cyst (firm/round) Location- on superficial layer of lamina propria(margin of vocal folds) Symptom: hoarseness Population affected- Young woman and professional voice users Appearance: asymmetry, absence of mucosal wave, mass/stiffness affected |
|
Sulcus Vocalis
|
Location: superficial layer
-furrow/ groove alond upper medial edge of epithelium Symptom: hoarseness, diminished vibrational amp, little mucosal wave Etiology uncertain, possibly abuse, congenital, trauma |
|
Sulcus Vocalis laryngoscopic signs
|
- depression along edge of vf
- diminished vibrational amp - little muscosal wave along vf edge |
|
Polyps
|
Polyps form blood supply and may hemmorhage,nodules do not
Location: unilateral Etiology: traumatic Simliar to nodule, differences in pathopysiology: - larger, vasular, inflammatory Symptoms: hoarsness, deep voice |
|
Vocal Nodule
|
Symptoms:
- hoarseness, recurrent - benign - blister like - decreased phonotory onset/ endurance Location: bilateral, on reinkes space (superficial layer) Etiology: chronic abuse Appearance: soft and watery at first, then turn hard tx: voice therapy |
|
Voal nodules pathophysiology
|
- submucosal edema
- hyalinization of reinkes space - thickening of epithelium - chronic behavior - blister soft an water and turn hard |
