  3. Symptoms
    1. Hoarseness
    2. Decreased endurance for speech and voice Fatigue
    3. Swallowing difficulty or Choking on liquids
    4. Singing difficulty
  4. Signs: Laryngoscopy
    1. Paralyzed vocal cord is fixed in paramedian position
      1. Just lateral to midline
      2. Slight adduction may be seen (collateral innervation)
    2. Paralyzed vocal cord is bowed and flaccid
      1. When speaking, drops lower than the unaffected cord
    3. Uninvolved vocal fold may compensate
      1. Uninvolved cord crosses midline over next 2-3 months
      2. Meets paralyzed cord
  5. Evaluation
    1. See Speech Exam
    2. Careful lymph node examination
      1. See Lymphadenopathy of the Head and Neck
  6. Radiology
    1. Chest XRay (consider lordotic views)
  7. Management: General
    1. Laryngology or ENT referral in most cases
    2. Early speech pathology for voice building Exercises
  8. Management: Surgery for unilaterally paralyzed vocal cord
    1. Medialization Laryngoplasty (Thyroplasty) with implant
      1. Various implant types (e.g. Gore-Tex, Silicon)
    2. Medialization via office injection
      1. Collagen injections
      2. Avoid Teflon augmentation due to granulation
    3. Reinnervation
      1. Requires more time to result than other procedures
  9. Complications
    1. Aspiration of food contents
