[Laryngeal changes following functional dysphonia]

Different clinical entities of functional voice disorders and their corresponding laryngoscopic findings are discussed. The visible changes must be regarded as functional consequences of muscular dystonia. The combination of laryngoscopic findings, auditive judgement and a complete history of the patient will allow the practitioner to establish a correct diagnosis without any need for special instruments. Conservative voice therapy however should be carried out by an experienced phoniatrician.
