Total remission or persistence of tinnitus and decreased sound level tolerance in adolescents with normal audiograms: A follow-up study

CONCLUSIONS: Tinnitus and reduced sound tolerance could feature early signals of hidden synaptic injury that is prevalent among adolescents and hidden from the audiogram. The strong relationship between both symptoms, in addition to low-level increases in hearing thresholds at high frequencies in the extended audiogram, poses a challenge for future hearing health and should be further evaluated as a possible intrinsic vulnerability for lesions following exposure to loud sounds. Moreover, the relationship between their spontaneous remissions may signal a possible synaptic repair, which has been reported in animal models.PMID:33637221 | DOI:10.1016/bs.pbr.2020.05.025
