Introduction
We assessed the efficacy of hyperbaric oxygenation therapy (HBO) for idiopathic sudden sensorineural deafness and considered concerning the adaptation standard of HBO.
Materials and Methods
A retrospective survey was conducted of 198 cases of idiopathic sudden sensorineural deafness treated at Kitasato University Hospital during the period from September 1998 to July 2005. The HBO group (124 patients) was treated by HBO, intravenous drip infusion of prostaglandin E
1, steroids, vasodilators, and vitamins. The No-HBO group (control group, 74 patients) was treated by all of the above methods except HBO.
We investigated the relationship between hearing recovery and HBO by logistic regression analysis.
Results
There were cases of cure in grades 4 of the HBO group, but it did not exist in Grade 4 of the No-HBO group. In regard to HBO There was no statistical significance in each grade.
Conclusion
Our study confirmed that as for HBO there is no necessity for grades 1, 2 and 3. In case of Grade 4 if the patient desires, we should treat with HBO.
