Abstract
This study investigates the physiological mechanism responsible for reappearance of phonation in an aphonic subject with traumatic laryngeal damage. The battery of procedures involved spectrography, laryngographic analysis, fiberoptic laryngoscopy, tomography, lateral xerography and cinefluorography. Results show that the subject's abnormal laryngeal anatomy facilitated a novel adductory mechanism for vocal fold vibration involving a type of sphincteric constriction between the arytenoid cartilages and the epiglottis. The value of a battery of diagnostic measures is highlighted.
Highlights
This study investigates the physiological mechanism responsible for reappearance ofphonation in an aphonic subject with traumatic laryngeal damage
Two cases of laryngeal trauma are discussed, and it is concluded that voice therapy is possible, even under highly adverse circumstances and following long periods of post-traumatic aphonia
This was consistent with superior displacement of the left vocal fold evident during indirect laryngoscopy and fiberoptic examination
Summary
Oedematous vocal cords; Some movement detected; Ventricular cord closure; No web Referred for further voice therapy. The vocal history is as follows: In January 1979 M. Between March and October of that year he received voice therapy resulting in low-pitched, severely hoarse phonation. He reported a gradual improvement in voice quality over the three years. After the medical examination and laser therapy in November 1982 he was referred for further voice therapy. At this stage it was suggested that nerve re-generation may have occurred to explain movement observed in the vocal cords (See Table 1)
