Abstract
ObjectiveThe present study aims to examine subjectively and objectively the voice changes in Bulimia Nervosa patients at different stages of treatment. MethodThe study was conducted with a study group including 10 patients followed up with a diagnosis of Blum,ia Nerrvosa and a control group consisting of 10 healthy participants of a similar age group without eating disorders. The reflux symptom index was used for stroboscopic evaluation. The fundamental frequency (F0), jitter, shimmer, and noise-to-harmonics ratio (NHR) were determined during acoustic voice analysis. Maximum phonation time was analysed. A subjective evaluation was performed using the Voice Handicap Index-10 (VHI-10). ResultsJitter, Shimmer, VHI-10 Score, and RFS values showed a statistically significant difference in the patient and control groups (p<0.05). The mean values of Jitter, Shimmer, VHI-10 Score, and RFS were higher in the patient group than in the control group. MPT did not differ between goups (p>0.05)Age and F0 (Hz) values showed no statistically significant difference in the patient and control groups (p>0.05). ConclusionIn BN patients, the laryngopharyngeal reflux mechanism causes negative effects on vocal cord examination and acoustic sound analysis parameters, leading to subjective dissatisfaction.
