The Relationship between Movements of False Vocal Folds on Phonation and Benign Vocal Folds Lesions

;;;

ABSTRACT

Background and Objectives
: Vocal abuse and misuse and muscle tension dysphonia that have various movements of false vocal folds may be related to the development of benign vocal folds lesions, such as vocal nodules, polyps, and cysts. This study was designed to determine whether benign vocal folds lesions were related with movements of false vocal folds on phonation. Material and Methods : One Hundred and seventy eight subjects were studied. All subjects received otolaryngological evaluation including videostroboscopy, objective voice measures. Patients were diagnosed as normal shape of vocal folds (group a), approximation of bilateral false vocal folds (group b), approximation of unilateral false vocal folds (group c), lateralized extension of false vocal folds (group d), and medialized approximation of posterior false vocal folds (group e). We analyzed the results of benign vocal folds lesions in each group.
Results
: Differences were found between the normal shaped group and the abnormal shaped group. No differences were found between each abnormal groups except group d and e.
Conclusion
: The shape of false vocal folds was related to the benign vocal folds lesions.
