Combination of voice therapy and antireflux therapy rapidly recovers voice-related symptoms in laryngopharyngeal reflux patients.

OBJECTIVE

Patients with laryngopharyngeal reflux frequently experience voice-related symptoms. This study was designed to investigate the effectiveness of combined voice and medical therapy in comparison with medical therapy alone in the improvement of voice-related symptoms and parameters in patients with laryngopharyngeal reflux.

STUDY DESIGN

Concurrent nonrandomized comparative trial.

SETTING

Otolaryngology department at a university hospital.

SUBJECTS AND METHODS

In this prospective study, 100 patients diagnosed with laryngopharyngeal reflux with voice symptoms were divided into 2 groups: 50 patients were treated with medication alone, and 50 were treated with medication plus voice therapy. The following data were recorded before treatment and at 1, 2, and 3 months posttreatment: reflux symptom index (RSI), reflux finding score (RFS), voice handicap index (VHI), perceptual analysis, and acoustic analysis. The numbers of patients showing clinically significant reductions in these parameters were compared between groups using the following cutoff values: change in RSI ≥5, change in RFS ≥3, change in VHI ≥15, and change in grade, roughness, breathiness, asthenia, and strain scale (GRBAS) ≥1.

RESULTS

Significantly more patients in the study group showed a clinically significant change in RSI, VHI, and GRBAS score at the 1-, 2-, and 3-month follow-up evaluations. No clinically significant change in RFS was achieved in either group at 1 or 2 months, but a significantly greater change was achieved in the study group at 3 months.

CONCLUSIONS

Voice therapy may help to restore reversible mucosal change secondary to acidic reflux, inducing rapid resolution of symptoms and shortening of the treatment period.
