[Unilateral recurrent nerve paralysis in suspected Lyme borreliosis].

Cranial nerve palsy can often be observed in Borrelia burgdorferi infection. A dysphonic patient with a long lasting left-sided recurrent nerve palsy was treated with ceftriaxone, an antibiotic drug for the therapy of Lyme borreliosis. On the 7th day of application the paretic vocal fold showed recovering movements up to regular vocal fold function and normal stroboscopic results. Clinical and serologic constellations and their therapeutical implications are discussed.
