Analysis of acutely exacerbated chronic tinnitus by the Tinnitus Handicap Inventory.

OBJECTIVE: To examine factors potentially contributing to acutely exacerbated chronic tinnitus initiation using the Tinnitus Handicap Inventory.
METHODS: Sixty acutely exacerbated chronic tinnitus out-patients were divided into two groups depending on whether hearing loss was aggravated or stable during tinnitus exacerbation. Total Tinnitus Handicap Inventory scores and scores for the three subscales (assessing functional limitations, emotional attitudes and catastrophic thoughts) were analysed.
RESULTS: Total Tinnitus Handicap Inventory scores did not differ between groups. In patients with acutely exacerbated chronic tinnitus and aggravated hearing loss, functional subscale scores were significantly higher after acutely exacerbated chronic tinnitus than at baseline, but catastrophic and emotional subscale scores did not change. In patients with acutely exacerbated chronic tinnitus and stable hearing loss, emotional subscale scores were significantly higher after acutely exacerbated chronic tinnitus than at baseline, but catastrophic and functional subscale scores did not change.
CONCLUSION: Elevated Tinnitus Handicap Inventory functional subscale scores might indicate further hearing loss, whereas elevated emotional subscale scores might be associated with negative life or work events.
