Post-traumatic cricothyroid joint dislocation is reported in the literature. Trauma of the laryngeal framework is the most common cause. As a result, spontaneous non-traumatic cricothyroid joint dislocation is very rarely described. We report the case of a patient with spontaneous cricothyroid joint dislocation with the aim of reporting the diagnostic and therapeutic findings related to this rare entity. History and physical examination may suggest diagnosis. Computed tomography scan can confirm diagnosis and detect coexistence of anatomic anomalies of the neck. Reduction of dislocation may be easily performed in outpatient setting, producing immediate relief from dysphonia and neck pain. As CTJ dislocation is a speech-related disorder, appropriate speech therapy is advisable in order to avoid relapse.
