| Frage | Antworten |
| The Voice Center Components | MULTIDISCIPLINARY CLINIC --Laryngeal Surgeon --High-def laryngeal imaging --Voice Specialized SLP --Voice lab with acoustics and aerodynamics |
| Voice Patients | teachers, preachers, lawyers, sales representatives, call center employees, entertainers, etc. All patients with hoarseness!! Anyone who relies on voice for livlihood |
| Laryngology involves... | Diagnosis and treatment of disorders of: airway voice elements of swallow |
| Largyngeal Function | Protection of airway Provision of Airway Phonation |
| Intrinsic Laryngeal Musculature (adductory muscles, abductory muscles, and tensor) | Adductory: lateral cricothyroid, thyroarytenoid, interarytenoid (bilateral innervation) Abductory: posterior cricoarytenoid Tensor: cricothyroid |
| Extrinsic Laryngeal Musculature Functions | Strap muscles and extrinsic muscles of tongue Elevators Depressors Function: Swallowing and Vocal Tract |
| Requirements of Phonation | -Adequate breath support -Approximation of vocal folds -Favorable vibratory properties -Favorable vocal fold shape -Control of length and tension |
| Process of videostroboscopy | Vocal Fold vibration 100-200 cycles per second Videostroboscopy illuminates different parts of the cycle and the human eye/brain fills in the gaps |
| Laryngeal Function Studies | Acoustical Measurements Quality/Perturbation Measurements Aerodynamic Measurements |
| Acoustical Measurements : | Frequency evaluation (mean fundamental frequency and frequency range) Intensity (mean speaking intensity) |
| Quality/Perturbation: | Quality/Perturbation: Jitter, Shimmer, Noise-to-Harmonic Ratio, Degree and number of subharmonics increased |
| Aerodynamic Measurements: | Vital capacity Maximum Phonation time Phonation Quotient S/Z Ratio (1.4 or greater = clinically significant) |
| Cough Reflex | Laryngeal Chemoreflex -Nociceptive nerve endings in mucosal epithelial cells of epiglottis, aryepiglottic folds, and interarytenoid space -Efferent = syperior laryngeal nerve -Afferent = recurrent laryngeal nerve |
| Laryngeal Chemoreflex (Cough Reflex) Heightened by... | Inflammation, infection, frequent stimulation |
| Cough (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 |
| Treatment for Chronic Cough/Irritable Larynx | Medical Tx SLP: Break/abort cough; prevent cough and further irritation |
| Respiratory Retraining Therapy: Vocal Cord Dysfunction, Irritable Larynx, Cough | Treat muscular etiology by relaxing larynx and pharynx Eliminate inefficiencies in phonation and coordinated phonation with respiration. |
| Respiratory Retraining Therapy: Low CO2 Syndrome, hyperventilation | Change blood gas composition Nasal breathing, relaxation, reduction of respiratory rate |
| Reinke's Edema | Swelling of superficial lamina propria Occurs in smokers "smokers voice" |
| Polypoid Corditis and Treatment | Treatment: Smoking cessation Microflap resection or KTP laser treatment |
| Airway Disorders | 1. Dynamic -vocal fold dysfunction -paradoxical vocal fold motion 2. Static -bilateral vocal fold paralysis -subglottic stenosis |
| Vocal Cord Dysfunction | 1. Paradoxical VF closure -Stridor -Exercise induced -Young, female, Type A 2. Laryngospasm -Reflux -Functional |
| Common Laryngeal Pathologies | Benign Malignant Functional Neurologic |
| Benign Largyngeal Pathology | Infectious Traumatic Inflammatory Examples: Granuloma, acute laryngitis, reflux, fungal laryngitis |
| Malignant Laryngeal Pathology | Example: Largyngeal Cancer |
| Functional Laryngeal Pathology | Example: Muscle Tension Dysphonia |
| Muscle Tension Dysphonia and Treatment | Recruitment 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) |
| Neurologic Laryngeal Pathology | Example: Unilateral vocal fold paralysis, Parkinson's, Spasmodic Dysphonia |
| Treatment of Vocal Fold Paralysis | Injection Laryngoplasty |
| Spasmodic Dysphonia and Treatment | Laryngeal Dystonia Adductor - vocal stops; Abductor - breathy; Mixed Tremor Treatment: Laryngeal Botox Injections; improve effort; weaken dystonia |
| Vocal Tremor | Intrinsic and extrinsic laryngeal muscles Present in 25-35% of patients with essential tremor Also seen in spasmodic dysphonia, Parkinson's, and Parkinson plus syndromes |
