OBJECTIVE: To investigate the voice features of laryngopharyngeal reflux (LPR), and analyze the effects of LPR to the life qualities of patients. To analyze the dependability between objective and subjective ways.
METHOD: One hundred and ninety-six of the patients who were suspected of LPR were received the surveys of general state, electronic nasopharyngolaryngoscope, evaluation of the reflux symptom index (RSI) and the reflux finding score (RFS). One hundred of patients whose RSI>13, RFS>7 were diagnosed as LPR and were received evaluation of voice handicap index (VHI), analysis of vocal acoustics and examination of glottogram.
RESULT: The funda mental frequency included male and female depressed,the perturbation of fundamental frequency, the perturbation of amplitude and normalization noise energy increased. Differences were statistically significant (P<0.01) compa ring with the normal control. The contiguity rate depressed, maximum phonation time shorten, the differences in which were statistically significant (P<0.01) comparing with the normal control. In the evaluation of VHI, the score of physiology was the highest, the function was second and the emotion was the lowest. The RSI and VHI had correlations (P<0.05), while RFS, RSI and VHI had not (P>0.05). Physiology, function and emotion had correlations in LPR.
CONCLUSION: From the analysis of vocal acoustics and examination of glottogram,we knew that vocal function was effected because the vocal cord was injured by LPR. The fundamental frequency depressed and the vibrations of vocal cords were not instability, glottis wasn't closed up well and contact time was depressed. Patients who had the reflux symptoms uncertainty had the reflux findings.
