Abstract

A clinical study of correct diagnosis by auscultation of voice was performed on 150 cases who complained of voice disorder at the Dept. of Otolarynglolgy of Ewha Womans university hospital recently and the following results were obtained.

1) The underlying diseases causing voice disorder in order of frequency were as that follows ; vocal polyp and nodule were 58 cases(38.6%), recurrent nerve paralysis were 26 cases(17.3%), laryngitis were 16 cases(10.7%), laryngeal cancer were 12 cases(8.0%).

2) Among total of 150 cases, male were 74 cases and female were 76 cases. Among 58 cases of vocal polyp and nodule, male were 22 cases(37.9%) and female were 36 cases(62.1%). Among 26 cases of recurrent nerve paralysis, male were 16 cases(61.5%) and female were 10 cases(38.5%). Among 16 cases of laryngitis, male were 6 cases(37.5%) and female were 10 cases(62.5%). Among 12 cases of laryngeal cancer, male were 8 cases (66.7%) and female were 4 cases (33.3%). Among 6 cases of mutation disorder, male were 6 cases(100%), Among 4 cases of anabolic steroid dysphonia, female were 4 cases (100%).

3) Results of auscultation of voice were as that follows ; The highest incidence of voice quality of vocal polyp and nodule in order frequency were BR factor(55.2%) and R factor(30.8%). Recurrent nerve paralysis in order frequency were AB factor(46.2%) and BR factor(30.8%). Laryngitis in order frequency were BR factor(43.8%) and R factor(31.3%). Laryngeal cancer in order frequency were BR factor(83.8%) and R factor(8.3%).

4) The rate of correct diagnosis by auscultation of voice were as that follows ; Correct diagnosis were 69%. Correct diagnosis inclued binary choice and correct diagnosis were 78%. Wrong diagnosis indicating similar pathlolgical conditions, correct diagnosis and correct diagnosis inclued in binary choice were 81%.
