Objectives : Vocal cord paralysis(VCP) is a complex disorder which may result from numerous causes. We reviewed and analyzed the trend of clinical characteristics and causes of VCP in Korean patient.
Method : A total 197 patients with VCP who visited St.Mary’’s hospital from March, 2000 to August, 2006 were reviewed retrospectively. They were analyzed according to sex, age, cause of VCP, position of paralyzed vocal fold, treatment methods.
Results : The male and female ratio was 1.6 : 1. The unilateral paralyzed vocal fold was fixed at paramedian position in 84% of the cases. The left vocal fold was paralyzed about 2 1/2 times as much as the right vocal fold. Among the causes of VCP 30.9% of the cases were due to postoperative paralysis, and most of those were developed after lung, mediastinal surgery. laryngeal EMG was performed in 47 patients for determines the prognosis and treatment method. In the unilateral VCP, 90 patients were treated with injection laryngoplasty, 21 patients were performed thyroplasty type I.
Conclusion : The causes of VCP include various diseases, so, detection of the primary disease is very important, because many fatal diseases are included among the primary diseases, and late detection can cause serious problems. VCP is not only a disease entity in itself, but can be seen as a sign of an underlying disease.
