[Idiopathic sudden deafness: the therapeutic evaluation of hyperbaric oxygen treatment].
OBJECTIVE
To further evaluate the therapeutic effect of hyperbaric oxygen (HBO) to idiopathic sudden deafness.


METHODS
A total number of 236 medical records of inpatients with idiopathic sudden deafness during 1997-2004 were collected from the Wuhan Union Hospital. Single factor analysis was done to evaluate the therapeutic effect with ten factors with SPSS analysis software. We divided the cases into HBO group and non-HBO group. The logistic regression was used in multivariate analysis.


RESULTS
Single factor analysis indicated that sex, ear side, presence of tinnitus, inducement and period of treatment had no effect on the prognosis, while age, course, presence of vertigo, a sensorineural hearing loss history with the other ear, degree of deafness had some effect on the prognosis. Multivariate analysis indicated: the effective (hearing threshold has elevated above 15 dB) ratio of HBO group comparing to the control group (non-HBO group), the difference was significant (P<0.01).


CONCLUSIONS
The first visit after 14 days, the presence of vertigo, a sensorineural hearing loss history with the other ear and complete deafness may imply poor prognosis. HBO is effective for sudden deafness.
