Functional endoscopic sinus surgery (FESS) can alter voice quality. While immediate post-surgery shows decreased nasality, long-term effects include a significant increase in resonance, impacting voice professionals.

Area of Science:

  • Otolaryngology
  • Speech Science

Background:

  • Chronic rhinosinusitis (CRS) affects many adults.
  • Functional endoscopic sinus surgery (FESS) is a common treatment for CRS.

Purpose of the Study:

  • To investigate the impact of FESS on voice resonance.
  • To assess subjective and objective changes in voice quality post-FESS.

Main Methods:

  • Forty adult CRS patients undergoing FESS were studied.
  • Subjective voice changes were assessed via questionnaire.
  • Objective nasality was measured using a Nasometer preoperatively and postoperatively (2 days and 1 month).

Main Results:

  • A decrease in nasalance was observed 2 days after FESS.
  • A significant increase in mean nasalance values occurred 1 month post-FESS.

  • FESS can lead to long-term changes in vocal tract acoustics.

    • Conclusions:

    • Functional endoscopic sinus surgery can significantly increase nasality long-term.
    • Clinicians should counsel patients, especially voice professionals, on potential voice quality changes after endonasal sinus surgery.
