Abstract:
The objective of this study was to investigate quality-of-life outcomes in patients with jaw-opening oromandibular dystonia who had received treatment with botulinum neurotoxin injections. The Glasgow Benefit Inventory (GBI) was used as a post-intervention questionnaire to measure patient benefit. Twenty-five questionnaires were sent to patients. Of the 12 patients who returned the form (48% response rate), the mean scores for the general GBI subscore (p = 0.001), the social support GBI subscore (p = 0.031), and the physical health GBI subscore (p = 0.002) demonstrated statistically significant benefit from the injections. No scores demonstrated a negative impact. Botulinum neurotoxin injections were demonstrated to benefit the quality of life in patients suffering from jaw-opening oromandibular dystonia.
