[Cervical dysphonia].

In patients with dysphonia, an increased tension of the muscles of the neck as well as of the prelaryngeal muscles is well known to all phoniatrists. Usually the cause of this tension is only seen in pathological phonation or in a psychic base. In the present report it could be demonstrated that this tension causes itself a functional dysphonia. This tension is produced by a functional deficit of the upper cervical spine. Chiropractic manipulation of the cervical spine can unlock the stiffness of the spine and normalize the voice within a few minutes.
