ABSTRACT
OBJECTIVE:
To explore whether use of baclofen as adjunct treatment to voice therapy (VT) led to improvement in subjective throat symptoms in patients with primary muscle tension dysphonia (MTD). MTD is associated with excessive paralaryngeal muscle contraction, and baclofen is a muscle relaxant. STUDYDESIGN:
Cross-sectional, questionnaire-based study.METHODS:
An initial pool of patients, who were diagnosed with primary MTD and received 1+ VT session(s) at a single tertiary-care center from 2015 to 2019, were placed into either a baclofen group (prescribed 10 mg baclofen t.i.d. PRN along with VT) based on symptomatology or non-baclofen group (VT alone). They were administered questionnaires via postage mail or phone that included the Voice Handicap Index-10 (VHI-10), Reflux Symptom Index (RSI), and other survey elements. A retrospective chart review collected demographic and other clinical data from recruited participants.RESULTS:
A total of 314 non-baclofen and 63 baclofen patients met the inclusion criteria of this study, with 37 non-baclofen patients (mean age = 47.5 years, 62.2% female) and 15 baclofen patients (mean age = 45.5 years, 73.3% female) recruited. There was no significant difference in mean [SD] VHI-10 scores (11.30 [8.20] vs. 12.60 [10.75]; p = 0.638) and RSI scores (13.46 [10.44] vs. 16.20 [10.65]; p = 0.398) between non-baclofen and baclofen groups, respectively.CONCLUSION:
There was no significant difference in voice psychometric outcomes between non-baclofen and baclofen groups, measured primarily by the VHI-10 and RSI questionnaire components. Further studies are warranted to assess the efficacy and safety of baclofen as a therapeutic option for MTD.Palavras-chave
