Abstract

Purpose: To compare post-operative vocal outcomes of a voice rest regimen versus no voice restrictions following micro-laryngeal surgery for benign glottic lesions.

Methods: This was a combined prospective and retrospective cohort study on 167 patients who underwent micro-laryngeal surgery for benign focal fold lesion removal. Participants were divided into two regimens: standard voice rest (n = 92) or no voice restriction (n = 75). The primary outcome was post-operative vocal improvement, evaluated using voice handicap index questionnaire (VHI-10), GRBAS scale, and computerised acoustic analysis (shimmer, jitter, and the harmonic-to-noise ratio). The secondary outcome was emergence of vocal fold mucosal abnormalities in the immediate post-operative period. Parameters were collected at baseline and at the last clinical visit.

Results: There was no statistically significant difference between the voice rest and no-voice rest groups regarding baseline parameters of age, gender, laryngeal pathology, and voice use. Improvement in GRBAS scale values and VHI-10 scores between pre- and post-operative periods between groups did not demonstrate any statistically significant differences (P = 0.5303 and P = 0.1457, respectively). Similarly, the results of computerized voice analysis also showed no differences between groups in terms of shimmer (P = 0.9590), jitter (P = 0.5692), and harmonic-to-noise ratio (P = 0.1871). No correlation was found between the post-operative vocal fold's mucosal abnormalities and the type of voice rest regimen.

Conclusion: Voice quality and wound healing were similar regardless of the type of voice rest regimen applied. No voice rest at all was as good as voice rest after micro-laryngeal surgery.
