PURPOSE: This study was undertaken to assess the impact of hemifacial spasm (HFS) and blepharospasm (BS) on quality of life (QOL) during long-term treatment with botulinum toxin injections. METHODS: Fifty-three patients with HFS and 32 patients with BS as well as two healthy age- and sex-matched control groups were included in the study. All participants independently completed the disease-specific questionnaire for QOL, the HFS-30, and the Thai Depression Inventory, and also provided a peak improvement score assessment. RESULTS: The disease severity in both patient groups revealed mild functional impairment. The scores of HFS-30 in HFS patients (four of 8 subscales) and BS patients (3 of 8 subscales) were significantly higher than the control groups. In both HFS and BS, depression scores were positively correlated with the HFS-30 scores, while peak improvement and educational level were inversely correlated with the HFS-30 scores. Patients with BS were more affected in Mobility and Activities of Daily Living than HFS patients. CONCLUSIONS: Both HFS and BS affect QOL both physically and mentally despite clinical improvement with botulinum toxin. Depression and peak improvement after injection were associated with the level of QOL.
