The Effects of Endoscopic Sinus Surgery on Voice Characteristics in Chronic Rhinosinusitis Patients

Functional endoscopic sinus surgery (FESS) is a standard treatment modality for patients with chronic rhinosinusitis (CRS) who have failed appropriate medical therapy. However, FESS entails modification of the upper airway tract that may alter phonatory resonance and produce voice changes. The effects of FESS on postoperative voice characteristics in patients with CRS have yet to be quantitatively assessed.

Patients with severe CRS who underwent FESS at a tertiary care referral center between May and October 2017 were prospectively enrolled. The Consensus Auditory-Perceptual Evaluation of Voice (CAPE-V) and the Voice Handicap Index (VHI) were used to quantitatively evaluate voice characteristics and quality of life, respectively. Preoperative and postoperative CAPE-V and VHI scores were compared with postoperative scores for each patient. Sino-Nasal Outcome Test (SNOT-22) scores were also obtained to assess changes in patient symptoms.

18 CRS patients undergoing FESS were enrolled. The average preoperative Lund-Mackay score was 14, indicating baseline severe CRS. Postoperative assessments demonstrated a statistically significant decrease in CAPE-V (45-27, p = .005) and VHI (10-4.7, p < .001) scores. These correlated with a statistically significant decrease in SNOT-22 scores (42-13, p < .001).

Patients with CRS experience a significant improvement in voice characteristics and vocal quality of life following FESS. Furthermore, this appears to correlate with a significant decrease in self-reported disease severity. These findings may augment the discussion of potential benefits of FESS to a new potential domain for voice quality.
