Inflammatory torticollis in children.

Acute torticollis is commonly seen in the pediatric emergency department. It often results from an inflammatory process that irritates the cervical muscles, nerves, or vertebrae. Posturing of the head occurs with unilateral spasm of the sternocleidomastoid muscle such that the child will position the head with the occiput rotated to the affected side and the chin rotated to the contralateral side. We recently treated 26 children who presented to the emergency department with acute nontraumatic torticollis. The most common causes were upper respiratory infection, sinusitis, otomastoiditis, cervical adenitis, and retropharyngeal abscess or cellulitis. Four patients had subluxation of the atlantoaxial joint as a result of the inflammatory process. Children with acute torticollis need careful evaluation for either overt or occult otolaryngologic infections. Computed tomography and magnetic resonance imaging are helpful in determining the cause of the acute torticollis and in ruling out rotatory subluxation of the atlantoaxial joint.
