Abstract
Purpose
Voice change may happen after upper airway manipulation. The current study aimed to evaluate voice change after open rhinoplasty.
Materials and Methods
The current cross sectional study was conducted on subjects undergoing open rhinoplasty. Three acoustic parameters (frequency, bandwidth, and amplitude) were evaluated before open rhinoplasty, three, seven, and ten months after the operation. Subjects' sounds in pronouncing M/N/A were examined. The acoustic factors were measured in the first and second nasal murmurs. Time is a predictive factor and multiple acoustic parameters were the outcome of the study.
Results
Twenty-five subjects were studied. Amplitude and bandwidth decreased for the vowel A after rhinoplasty. However, frequency increased for pronouncing A. In constants, M and N, amplitude decreased after rhinoplasty. Unlike vowels, bandwidth increased in consonants. As vowels, frequency increased in consonants.
Conclusion
It seems that open rhinoplasty affects voice quality. Open rhinoplasty altered frequency, amplitude, and bandwidth of vowels and consonants during 10 months.
