title: Combined glottographic measurement of vocal cord paralysis in the outpatient clinic.
abstract: Recordings by combined glottography of vocal cord movements in patients with a vocal cord palsy were compared with a control group. In paralysis of the vocal cord the open quotient (OQ) is increased and the speed quotient (SQ) decreased. This system may have potential in the diagnosis and continued assessment of laryngeal abnormalities as well as providing a permanent objective record in medico-legal cases.
