ABSTRACT
BACKGROUND AND OBJECTIVES:
Pharyngeal neurosis is a common problem in the otolaryngology clinic. Laryngopharyngeal reflux is suggested as one of the etiologic factors in pharyngeal neurosis. The purpose of this study was to find usefulness of voice analysis in diagnosis of pharyngeal neurosis and correlation between voice analysis and 24-hour ambulatory double-probe pH monitoring. MATERIALS ANDMETHODS:
42 patients with pharyngeal neurosis underwent fiberoptic laryngoscopy, voice analysis, and 24-hour ambulatory double-probe monitoring. The authors used a computerized acoustic analysis pr-ogram (CSL-MDVP) to measure fundamental frequency, jitter, shimmer, and noise to harmonics ratio.RESULTS:
There was a significant difference between the positive group and negative group during 24-hour ambulatory pH monitoring regarding jitter and shimmer. Correlation results were good between voice analysis and 24-hour ambulatory double-probe pH monitoring, poor between fiberoptic laryngoscopy and 24-hour ambulatory double-probe pH monitoring.CONCLUSION:
This study showed that when abnormal results in voice analysis were found in patients of pharyngeal neurosis, the probability that 24-hour ambulatory double-probe pH monitoring would be abnormal was high.
