Abstract

Objective: The aim of the study is to compare the short-term effect of 7 versus 3 days of voice rest (VR) on objective vocal (acoustic) parameters following phonosurgery. Methods: A prospective randomized study conducted at a tertiary referral medical center. Patients with vocal fold nodules, polyps, or cysts and scheduled for phonosurgery were recruited from the Voice Clinic. They were randomized into groups of 7- or 3-day postoperative VR periods and their voices were recorded preoperatively and at 4-week postoperatively. A mixed linear model statistical analysis (MLMSA) was used to compare pre- and postoperative jitter, shimmer, harmonic-to-noise ratio, and maximum phonation time between the two groups. Results: Sixty-five patients were recruited, but only 34 fully complied with the study protocol, and their data were included in the final analysis (19 males, 20 females; mean age: 40.6 years; 17 patients in the 7-day VR group and 16 in the 3-day VR group). The groups were comparable in age, sex, and type of vocal lesion distribution. The preoperative MLMSA showed no significant group differences in the tested vocal parameters. Both groups exhibited significant (p < 0.05) and comparable improvement in all vocal parameters at postoperative week 4. Conclusions: A VR duration of 7 days showed no greater benefit on the examined vocal parameters than the 3-day protocol 4-week postoperatively. Our results suggest that a 3-day VR regimen can be followed by patients who undergo phonosurgery without compromising the vocal results. Larger-scale and longer-duration studies are needed to confirm our findings. Level of Evidence: 2 Laryngoscope, 2024.
