[The pathogenesis and treatment exploration of vocal cord paralysis].

OBJECTIVE

To investigate the causes and effective treatment of vocal cord paralysis(VCP).

METHOD: Sixty-five patients with VCP in our hospital in recent 10 years were analyzed. All the patients underwent examination by indirect laryngoscope, stroboscopy or electrolaryngostroboscopy, of which, 31 cases were operated by stiring arytenoid cartilage.

RESULT: Fourteen cases with VCP were caused by neck and thoracic tumor; Nine cases were caused by infectations; sixteen cases were caused by neck, thoracic, abdominal openations; twelve cases were caused by trachea intubation; Three cases were caused by gastric intubation; Eleven cases were caused without obvious reason. All the symptoms of VCP were cured after treatment in 37 cases. The improvement rate of hoarseness was 58.46%.

CONCLUSION

Patients with hoarseness should be routinely examinated by indirect laryngoscope, stroboscopy or electrolaryngostroboscopy. Arytenoid cartilage of patients with VCP should be stired by indirect laryngoscope or direct laryngoscope or self-retaining laryngoscope as early as possible.
