18 April 2018 (online)
discuss about reasons and possibilities of compensation and decompensation mechanism in chronic tinnitus treatment.
Material and method: Data came from China sudden hearing loss multiple center clinical study, from Aug. 2007 to Oct.2011, collected 1024 single-side sudden hearing loss patients in 33 hospitals and 922 patients (90.04%) combined with tinnitus, gave them standard treatment according to study design and observed the result after one month, total improvement rate of tinnitus reached 85.03%, improvement rate of hearing reached 77.44%, we followed up 192 patients one year, approximate 90% patients could adapt the tinnitus combined with sudden hearing loss with time prolonging.
1. Improvement of tinnitus has positive correlation with hearing recovery. 2 Acute tinnitus combined with hearing loss need to treatment as soon as possible, early intervention can shorten the improvement period of tinnitus. 3 Even the hearing can't recover with time prolonging, most of tinnitus can be compensated, indicate that acute tinnitus caused by pure hearing loss won't develop to chronic tinnitus.
1. Tinnitus caused by pure hearing damage/loss such as sudden hearing loss will be self-compensated around one year. The decompensation of chronic tinnitus usually caused by more than one reasons such as sleeping disorder, migraine, OSAHS, regurgitation of gastric juice, etc. 2. Improve the cognitive function of central nervous system, stabilize the peripheral lesions, and reduce the inhibition of central nervous system will be effective for tinnitus compensation.
