Inner ear hair cells are nerve cells. As long as it is damaged, both auditory cells and auditory nerves will degenerate and necrosis after a period of time, and it is difficult to recover. At present, all kinds of basic research and experiments do not have enough evidence to show that human auditory cells and auditory nerves can be repaired and regenerated after long-term injury. Practice has also proved that long-term sensorineural deafness is ineffective regardless of drugs, surgery, acupuncture, qigong and other treatments.
