The Relationship between The Voicing Method and Vocal Fold Nodule located in Different levels

;;;

ABSTRACT

Background and Objectives
: The vocal fold nodules which were made by excessive contact or vibration of the vocal folds were classified to the soft nodule and the hard nodule in according to the hardness or the duration of nodule. Sometimes laryngologist saw the nodule to be located in different level. Authors thought that each nodule to be located in different level might have the different causes. Therefore we studied to know the relationship between the voicing technique and each vocal fold nodule to be located in different level.
Materials and Method
s : One-hundred forty nine patients who had the vocal fold nodule were evaluated. Sites and shapes of the vocal fold nodules were investigated using videostroboscopy. Videokymography was also used to scan the center of the vocal fold nodules during phonation and classified to several types. Same procedures were done on normal subject while he simulated the various types of voicing. And we compared the findings between both of them. Three different types of lesion can be distinguished. These are ML group that lesions were located from mid to low, MH group that lesions were located from mid to upper and HL group that lesions were located from lower to upper of the vocal folds.
Results
: The VKG findings of ML group and situation simulating with hard glottal attack and vocal fry were similar. MH group had a similar VKG findings with situation simulating with whispering or high pitch voicing. HL group had a similar VKG findings with situation simulating with loud voicing.
Conclusion
s : Authors thought that each vocal fold nodule, which had different shapes and located in different level, related with the different types of voicing.
