The literature published on CLS suggests (although does not strictly prove) that laryngeal clicking sounds are caused by friction between the superior cornu or the top edge of the thyroid cartilage and the hyoid, or alternatively due to contact of these structure with the cervical spine. Seldom do patients report a former laryngeal trauma. The causes of the associated pain remain unclear. The treatment of choice seems to be resection of the structures associated with the clicking noise by thyroplastic surgery or reduction of the hyoid bone greater horn. It is therefore important to inform patients with mild CLS that these clicking sounds are harmless and to advise CLS patients suffering from pain of the appropriate treatment options.
