bretahy
Classifications of Voice Disorders
- Phonotrauma
- Organic
- Functional
- Psychogenic
- Neurological
Phonotrauma definition
results from misuse or abuse of the vocal mechanism
Organic definition
results from a disease process or may be congenital, i.e., cancer, acid reflux, laryngeal web etc.
Functional definition
Muscle tensions dysphonias
Psychogenic definition
results from an underlying psychological issue and presents no identifiable vocal pathology
Neurological definition
results from damage to the RLN or SLN, disease processes that affect these nerves, or brain injuries or lesions
Leukoplakia and Hyperkeratosis
Pre-cancerous lesions
- range from flat plaque-like whitish patches (leukoplakia) to warty lesions (keratosis).
- Increases VF mass and stiffness, decreases mucosal wave and amplitude, irregular glottic closure, aperiodicity ,
- VFs are asymmetric
Sulcus vocalis
- A longitudinal groove or indentation in the upper edge of the VFs that parallels the free margins
- may be caused by phootrauma, smoking, congenital
Laryngeal Cancer
- Globus sensation – ‘full feeling’ in throat
- May observe inhalatory stridor
- Throat pain, painful swallowing, problems swallowing, shortness of breath, halitosis
Three categories of phonatory dysfunction:
Adduction / Abduction problems
Stability problems
Coordination problems
Stability phonatory dysfunction
Parkinson’s, ALS
Essential Tremor
Coordination phonatory dysfunctio
Abductor Spasmodic Dysphonia
Adduction / Abduction problems
Vocal Fold Paralysis Vocal Fold Paresis SLN Paralysis Pseudobulbarpalsy Adductor Spasmodic Dysphonia Huntington’s Chorea
Paralysis in the adducted position causes
- Strained/strangled, monotone, low pitched, low volume voice w/ possible hypernasality
- Respiratory compromise due to decreased airway and stridor may be heard
Paralysis in the abducted position causes
- Aphonia.
* Lack of airway protection for swallowing
Management of Bilateral VF Paralysis
Abductor paralysis
- If airway is acceptable, wait and see if nerves spontaneously recover
- Cordectomy, Arytenoidectomy or VF lateralization
Causes of Bilateral VF Paralysis
Abductor paralysis
PCA is paralyzed
VFs in medial or paramedian position
Causes of bilateral Adductor paralysis
TA, LCA & IA are paralyzed
-VFs in abducted position
Management of Bilateral VF Paralysis
- Tracheostomy for safe swallow
2. AC medial rotation
Unilateral VF Paralysis Causes:
- Unilateral RLN injury
- idiopathic
- tumor, trauma, etc
SLN paralysis:
Effect on phonation:
inability to raise pitch
decreased pitch range
decreased VF closure
SLN Perceptuall charactersitics
decreased habitual pitch
breathiness
decreased pitch and intensity ranges
