  1. Epidemiology
    1. Incidence highest over 60 years old
    2. Men more commonly affected
  2. Pathophysiology
    1. Squamous Cell Carcinoma (90% of malignant larynx)
  3. Risk
    1. Tobacco abuse
    2. Alcohol Abuse
    3. Elderly
  4. Symptoms
    1. Chronic Hoarseness (longer than 2 weeks)
    2. Pharyngitis
    3. Otalgia
    4. Dysphagia
    5. Dyspnea
  5. Signs: Laryngeal Exam
    1. Early Findings
      1. Small, white Plaques or erythematous Nodule
      2. Findings may be subtle
    2. Advanced findings
      1. Exophytic mass lesion or Ulceration on vocal cords
      2. Immobility of the vocal cord may suggest invasion
  6. Management
    1. Surgical excision with or without radiation
  7. Prognosis:
    1. Five year survival if lesion on true cords: >80%
    2. Five year survival if lesion above true cords: >50%

Definition (MSH)Cancers or tumors of the LARYNX or any of its parts: the GLOTTIS; EPIGLOTTIS; LARYNGEAL CARTILAGES; LARYNGEAL MUSCLES; and VOCAL CORDS.
Definition (CSP)new abnormal laryngeal tissue that grows by excessive cellular division and proliferation more rapidly than normal and continues to grow after the stimuli that initiated the new growth cease; includes cancers or tumors of the larynx or any of its parts, the glottis, epiglottis, laryngeal cartilages, laryngeal muscles, and vocal cords.
