Laryngeal crepitus: an aid to diagnosis in non-fatal strangulation.
Examination of victims exposed to strangulation is well known in clinical forensic medicine. Not all cases show the objective signs to be found at the examination, e.g. petechial haemorrhages in the eyes and face as well as bruises and abrasions on the neck. In cases without objective signs especially, examination of the laryngeal crepitus might be an aid to diagnosis in strangulation. Laryngeal crepitus is felt by the examiner when the larynx is moved from side to side with a slight posterior pressure. When absent, it is a clinical sign of a mass in the retrolaryngeal space or hypopharynx, probably due to a laryngeal trauma. This paper describes three cases of strangulation where the clinical examinations showed a temporary absence of laryngeal crepitus.
