Larynx and Voice Disorders • Introduction • Anatomy • Physiology • Methods of evaluation • Common Disorders • Treatments • Conclusions
Larynx and Voice Disorders • Objectives • Learn to obtain Pertinent History & Physical • Know the appropriate work-up for disorders • Know when to refer • Know Medical Options and Surgical Options
Larynx and Voice Disorders Introduction • Very common problems • Multiple contributing factors • Psychologic factors contibute to vocal problems • Voice is one of our most unique identifiers • Patients are extremely happy if voice returns to “normal”
Larynx and Voice Disorders Anatomy • Skeletal Framework • Muscular Structures • Blood Flow • Nervous Input • Connective Tissues • Surface Tissues “Froggy” from the Little Rascals

Larynx and Voice Disorders Physiology “What does the larynx do?” • Airway Protection during Swallowing 2. Phonation • Resistance for Respiration • Chest Fixation to bear down
Larynx and Voice Disorders Voice Disorders occur if Patients have abnormal Anatomy or Physiology or BOTH
Larynx and Voice Disorders- Methods of Evaluation - Objective # 1 Learn to obtain Pertinent History & Physical Objective # 2 Know the appropriate Work-up for Disorders
Larynx and Voice Disorders- Methods of Evaluation - Objective # 1 Learn to obtain Pertinent History & Physical History • Feeling as if there is a mass in one’s neck with abnormal anatomy • Loss of one or more functions
Larynx and Voice Disorders- Methods of Evaluation - Objective # 1 History – due to mass effect 1. Difficulty Swallowing with choking on liquids • Extra force needed to get voice • Increased effort to take a breath. 4. Feeling of lump in one’s throat.
Larynx and Voice Disorders- Methods of Evaluation - Objective # 1 History – due to loss of function • Vocal fatigue • Unreliable voice with delayed voice initiation • Low, gravelly voice with low pitch • Voice breaks in first passages of sentences • Airy or breathy voice • Inability to sing in high, soft voice 7. Hoarse and rough voice quality 8. Frequent throat clearing
Larynx and Voice Disorders- Methods of Evaluation - Objective # 1 • History - Serious Complaints • Pain • Bleeding • Visual Change in Appearance of Larynx • Otalgia with no other ear complaints • Halitosis • Noisy Breathing • Weight Loss
Larynx and Voice Disorders- Methods of Evaluation - Objective # 1 Physical Examination 1. External a. Inspect Neck for Distortion and Asymmetry of the Larynx. b. Palpate Neck for Normal Firmness and Crepitance c. Listen for Abnormal Voicing or Breathing
Larynx and Voice Disorders- Methods of Evaluation - Objective # 1 Physical Examination 2. Internal a. Indirect Mirror Exam of the Larynx b. Flexible Nasolaryngoscopy c. Rigid Fiberoptic Laryngoscopy d. Video-stroboscopy e. If not tolerable of Office exam, Direct Laryngoscopy in OR f. Microscopic or Telescopic Laryngoscopy in the OR
Larynx and Voice Disorders- Work-up for the disorder - • Objective #2 Additional Work-up depends upon one’s index of suspicion after completing the history and the physical examination. Work-up is tied into the suspected cause.
Larynx and Voice Disorders- Work-up for the disorder - • Objective #2 1. Analysis of Masses with Structural Issues - CT Scans to examine larynx for tumor - MRI is useful for soft tissue masses - CT-PET Scan for suspected cancers - Ultimately, unresolved masses need to be biopsied or removed
Larynx and Voice Disorders- Work-up for the disorder - • Objective #2 2. Analysis of Functional Laryngeal Problems - Videostroboscopy for voice changes - Laryngeal EMG is muscle weakness or nerve paralysis suspected - Modified Barium Swallow for aspiration - FEES for aspiration concerns - Ultrasound, possibly for laryngomalacia - Laryngeal Culture if suspected Infection
