Abstract:

ObjectiveIn    order to increase the curative effect, the effects of different hyperbaric oxygen therapy plans and the courses of treatment on sudden deafness were explored． Methods   80 cases of sudden deafness were divided into two groups respectively( each group with 40 cases). Hyperbaric oxygen treatment was given before (group A) or after the drug treatment(group B) on every day morning.  Drug treatment lasted for 23 weeks, while The hyperbaric oxygen treatment was repeated for 13 courses.One course of the treatment was 10 days. Results   Total effective rates were significantly different between group A(77.5%, 31/40) and B(55.00%, 22/40) (χ2=4.528，P=0.033). There was no difference between the first course of hyperbaric oxygen treatment and the second or 3rd course. Conclusions   For the patients with sudden deafness, it is better to apply the hyperbaric oxygen treatment after the drug treatment than the contrary.Because the first course of hyperbaric oxygen treatment has shown good curative effect, it is unnecessary to increase the courses.
