--Voice lab with acoustics and aerodynamics - 2Voice Patientsteachers, preachers, lawyers, sales representatives, call center employees, entertainers, etc.
All patients with hoarseness!!
Anyone who relies on voice for livlihood - 3Laryngology involves...Diagnosis and treatment of disorders of:
airway
voice
elements of swallow - 4Largyngeal FunctionProtection of airway
Provision of Airway
Phonation - 5Intrinsic Laryngeal Musculature (adductory muscles, abductory muscles, and tensor)Adductory: lateral cricothyroid, thyroarytenoid, interarytenoid (bilateral innervation)
Abductory: posterior cricoarytenoid
Tensor: cricothyroid - 6Extrinsic Laryngeal Musculature FunctionsStrap muscles and extrinsic muscles of tongue
Elevators
Depressors
Function: Swallowing and Vocal Tract - 7Requirements of Phonation-Adequate breath support
-Approximation of vocal folds
-Favorable vibratory properties
-Favorable vocal fold shape
-Control of length and tension - 8Process of videostroboscopyVocal Fold vibration 100-200 cycles per second
Videostroboscopy illuminates different parts of the cycle and the human eye/brain fills in the gaps - 9Laryngeal Function StudiesAcoustical Measurements
Quality/Perturbation Measurements
Aerodynamic Measurements - 10Acoustical Measurements :Frequency evaluation (mean fundamental frequency and frequency range)
Intensity (mean speaking intensity) - 11Quality/Perturbation:Quality/Perturbation: Jitter, Shimmer, Noise-to-Harmonic Ratio, Degree and number of subharmonics increased
- 12Aerodynamic Measurements:Vital capacity
Maximum Phonation time
Phonation Quotient
S/Z Ratio (1.4 or greater = clinically significant) - 13Cough ReflexLaryngeal Chemoreflex
-Nociceptive nerve endings in mucosal epithelial cells of epiglottis, aryepiglottic folds, and interarytenoid space
-Efferent = syperior laryngeal nerve
-Afferent = recurrent laryngeal nerve - 14Laryngeal Chemoreflex (Cough Reflex) Heightened by...Inflammation, infection, frequent stimulation
- 15Cough (types and descriptions)1. Behavioral/Habitual
-Lasts longer than 8 weeks
-Concomitant with other pulmonary or GI comorbidities
-Quality of life implications
2. Neurologic/Psychogenic - 16Treatment for Chronic Cough/Irritable LarynxMedical Tx
SLP: Break/abort cough; prevent cough and further irritation - 17Respiratory Retraining Therapy: Vocal Cord Dysfunction, Irritable Larynx, CoughTreat muscular etiology by relaxing larynx and pharynx
Eliminate inefficiencies in phonation and coordinated phonation with respiration. - 18Respiratory Retraining Therapy: Low CO2 Syndrome, hyperventilationChange blood gas composition
Nasal breathing, relaxation, reduction of respiratory rate - 19Reinke's EdemaSwelling of superficial lamina propria
Occurs in smokers
"smokers voice" - 20Polypoid Corditis and TreatmentTreatment:
Smoking cessation
Microflap resection or KTP laser treatment - 21Airway Disorders1. Dynamic
-vocal fold dysfunction
-paradoxical vocal fold motion
2. Static
-bilateral vocal fold paralysis
-subglottic stenosis - 22Vocal Cord Dysfunction1. Paradoxical VF closure
-Stridor
-Exercise induced
-Young, female, Type A
2. Laryngospasm
-Reflux
-Functional - 23Common Laryngeal PathologiesBenign
Malignant
Functional
Neurologic - 24Benign Largyngeal PathologyInfectious
Traumatic
Inflammatory
Examples: Granuloma, acute laryngitis, reflux, fungal laryngitis - 25Malignant Laryngeal PathologyExample: Largyngeal Cancer
- 26Functional Laryngeal PathologyExample: Muscle Tension Dysphonia
- 27Muscle Tension Dysphonia and TreatmentRecruitment of extralaryngeal muscles during phonation
Compensatory maneuvers
Alters glottic and vocal tract configuration and closure
Cervicalgia (tightness and pain in cervical musculature)
Treatment: Voice therapy & physical therapy to treat upper body tension (neck, back, and shoulders) - 28Neurologic Laryngeal PathologyExample: Unilateral vocal fold paralysis, Parkinson's, Spasmodic Dysphonia
- 29Treatment of Vocal Fold ParalysisInjection Laryngoplasty
- 30Spasmodic Dysphonia and TreatmentLaryngeal Dystonia
Adductor - vocal stops; Abductor - breathy; Mixed
Tremor
Treatment: Laryngeal Botox Injections; improve effort; weaken dystonia - 31Vocal TremorIntrinsic and extrinsic laryngeal muscles
Present in 25-35% of patients with essential tremor
Also seen in spasmodic dysphonia, Parkinson's, and Parkinson plus syndromes
