title: [Cranio-cervical junction malformations: a rare cause of bilateral vocal cord paralysis].
abstract: OBJECTIVE
  To report a rare and reversible cause of bilateral vocal cord paralysis in an adult.
  
  
  METHODS
  A 44 years old woman has consulted for a laryngeal stridor with hoarseness. This symptomatology was preceded by chronic headache and dizziness. The examination noted bilateral vocal cord paralysis in paramedian position, and a cerebellum syndrome. The patient underwent urgent tracheotomy.
  
  
  RESULTS
  A magnetic resonance imaging was performed for the etiologic research, and revealed a Chiari I malformation with a compression of the bulb. Neurosurgical decompression permitted resolution of the symptoms, and selvage of the tracheotomy was possible 2 months after surgery.
  
  
  CONCLUSIONS
  Bilateral vocal cord paralysis is rare on Chiari I malformation. It's secondary to a direct compression or an ischemia of the brain stem. The oto-rhino-laryngologists have to know this etiology to make the diagnosis early and permit a neurosurgical treatment.
