  • Title: [Cranio-cervical junction malformations: a rare cause of bilateral vocal cord paralysis].
    Author: Benhammou A, Benbouzid MA, Bencheikh R, Boulaich M, Essakali L, Kzadri M.
    Journal: Ann Otolaryngol Chir Cervicofac; 2007 Jun; 124(2):72-5. PubMed ID: 17481568.
    Abstract:
    OBJECTIVES: To report a rare and reversible cause of bilateral vocal cord paralysis in an adult. MATERIAL AND 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.
