ABSTRACT

Background and Objectives:
Benign vocal fold lesions have shown various voice onset types on phonation, however, they have not been documented yet. We studied to know the relationships between benign vocal fold lesions and voice onset types.
Materials and Method:
114 subjects were evaluated by using videokymographic examinations. The subjects were classified into three types: normal, contact, and open types according to the patterns of voice onset types on phonation. Benign vocal fold lesions were investigated and voice onset types were compared between normal and disease groups. Voice parameters were obtained from and compared in all subjects to assess acoustic and aerodynamic factors.
Results:
The normal type among onset types were more than contact type or open type in both normal and disease groups. Disease group showed many contact and open types when. compared with normal group. Vocal nodule and vocal polyp were showed many normal and contact types, however, sulcus vocalis was almost showed open type among voice onset groups. The values of mean flow rate (MFR) of contact type were significantly higher compared to normal type in disease group (p<0.05). Shimmer of contact type was higher than normal type in diseasegroup, but the difference was not significant (p=0.057).
Conclusion:
Benign vocal fold lesions were related to the various types of voice onset. The various types of voice onset should be considered when benign vocal fold lesions were examined.
