Hemifacial spasm associated with otitis media with effusion: A first reported case

Hemifacial spasm is a condition consisting of unilateral paroxysmal involuntary contractions of the muscles innervated by the facial nerve. The most common etiology is a vascular loop compression at the root exit zone of the nerve. We present here a first reported case of hemifacial spasm associated with otitis media with effusion, in a 6-year-old girl, which was relieved immediately following ventilation tubes insertion. A proposed mechanism is described.
