CLINICAL NOTE Clicking in the Throat Cinematic Fiction or Surgical Fact?

he complaint of a clicking in the throat when swallowing is uncommon but very dis- comforting and painful for those who experience it. It is such an unusual complaint that symptoms may be dismissed as psychogenic because a cause for the problem may not be readily apparent. We present a series of 11 cases in which all patients had an Taudible clicking or popping noise in the throat associated with and throat pain when swal- lowing or turning the neck. The most helpful diagnostic procedure was careful examination and palpation of the neck while the patient swallowed to localize the side and source of the clicking. Laryngeal computed tomographic (CT) scans helped in some cases to demonstrate thyroid- cartilage and/or vertebral body asymmetry. Each case was treated with surgery of the neck and to trim the portion of the thyroid cartilage causing the clicking. In most cases the superior cornu of the thyroid cartilage projected posteriorly and medially. Surgery was successful in all cases to eliminate the symptoms. Though an uncommon complaint, our experience suggests that the clicking throat is a surgically treatable problem. Arch Otolaryngol Head Neck Surg. 2001;127:1129-1131
