An analysis of vocal cord paralysis before and after Teflon injection using combined glottography

Combined glottography shows clinical potential but has only had limited use in monitoring laryngeal function before and after surgery. Eight patients undergoing Polytetrafluoroethylene (Teflon) injection for unilateral vocal cord palsies had pre- and post-operative combined glottography performed. G...

Summary:Combined glottography shows clinical potential but has only had limited use in monitoring laryngeal function before and after surgery. Eight patients undergoing Polytetrafluoroethylene (Teflon) injection for unilateral vocal cord palsies had pre- and post-operative combined glottography performed. Grossly abnormal waveforms pre-operatively confirmed poor glottic closure and irregular vibratory cycles. Analysis was difficult. Post-operatively all patients had a marked improvement in voice. Combined glottography showed a clear recovery of the waveforms towards normal with resumption of the two-mass model of glottal movement. Analysis was greatly simplified. Objective records were produced.
