Pathological auditory adaptation is generally characterized by a decrease in the perception of stimulating sounds and sounds of similar frequency. Some studies have shown that auditory adaptation can occur in both ears when sound is applied to only one auditory organ. This suggests that the mechanism of auditory adaptation is central. If the auditory organs are subjected to strong auditory stimuli for a long period of time, the resulting decrease in auditory perception often takes a day or night or even a few days to recover. 1. First of all, treat the cause such as applying antibiotics and surgical treatment for patients with otitis media complicated by labyrinthitis; surgical treatment should be performed for deafness caused by tumors in the cerebral pontocerebellar angle; deafness caused by drug intoxication should be stopped immediately. Intrathecal, ventricular and intracerebral pool injections of gentamicin and streptomycin should be avoided as much as possible. 2. Drug treatment There is a lack of drugs with definite efficacy. B vitamins, vasodilators (niacin, dibazol, calcium channel blockers, etc.) should be given as clinically appropriate treatment. 3.If necessary, try hyperbaric oxygen therapy Hyperbaric oxygen therapy is to breathe pure oxygen in an environment with more than one atmosphere pressure. Hyperbaric oxygen therapy provides a new scientific and effective adjuvant therapy for the treatment of traumatic brain injury, which is of great practical significance to improve the prognosis of traumatic brain injury patients, increase the cure rate and reduce the disability rate. 4.Other Acupuncture also has certain therapeutic effect; wearing hearing aids can improve the hearing condition of patients.
