Summary

Sinus surgery significantly alters speech acoustics and perceived nasality. These changes in speech production and perception are measurable and may inform patient counseling.

Area of Science:

  • Otolaryngology
  • Speech Science
  • Acoustic Analysis

Background:

  • Sinus surgery impacts upper airway anatomy.
  • Potential effects on speech production and resonance are not fully understood.

Purpose of the Study:

  • To investigate the effects of sinus surgery on speech production and perception.
  • To analyze acoustic changes in nasal sounds post-surgery.

Main Methods:

  • Vocal recordings analyzed before and after sinus surgery.
  • Acoustic spectral analysis of nasal consonants and vowels.
  • Perceptual analysis of nasalized vowels by trained phoneticians.

Main Results:

  • Significant differences in spectral properties of speech post-surgery (P < .001).
  • Postoperative changes in perceived nasality for specific vowels.
  • Acoustic measures correlated with perceptual changes in nasality.

Conclusions:

  • Sinus surgery measurably affects acoustic signal and perceived speech nasality.
  • Acoustic correlates of speech changes can aid preoperative patient counseling.
