Keywords: Head & Neck/ENT, TreatmentIn this study, we performed brain surface-based morphometry to evaluate changes in sulcal depth after sound therapy in patients with idiopathic tinnitus. Our results showed thatsulcal depth was signiêcantly reduced in the left medial temporal cortex (MTC) and right somatosensory and motor cortex (SMC) of patients with tinnitus compared to the healthycontrols, but increased signiêcantly at 24 weeks after sound therapy. Therefore, sulcal depth in the auditory sensory regions of the brain is a potential neuroimaging biomarker forevaluating treatment eìcacy in tinnitus patients.
