Focal ohc
WebATP is a major contributor to the response of type II cochlear afferents to focal OHC ablation (Liu et al., 2015). WebJun 11, 2024 · Each cochlea has a focal OHC lesion (left, 0.05 mm; right, 0.06 mm) centered in the area of maximum threshold shift. At the same cochlear location, there were three additional narrow lesions (left, one; right, two) in which OHC loss ranged from 42–44% (i.e., slightly less than the 50% criterion for a focal lesion).

Research suggests that A2M may potentially halt the degenerative process in arthritis.

WebDPOAE levels are useful for detecting broad OHC losses of greater than 10% and large focal OHC lesions greater than 0.6 mm. Absence of significant differences in DPOAE amplitude across groups does not rule out the absence of subtle cochlear lesion in the study group.
