OBJECTIVE: To investigate the effect of hyperbaric oxygen therapy to different degrees of hearing loss and different types of threshold curve in sudden deafness patients, and establish a personalized therapy, so as to promote clinical effect to sudden deafness. METHOD:One hundred and twenty cases were divided into two groups respectively (each group 60 cases). Drug treatment had been used in group A for two weeks. The patients in group B received drug treatment combined with hyperbaric oxygen therapy for two weeks. According to the different degrees of hearing loss and the types of audiogram in two groups, the statistical analysis to the difference of hyperbaric oxygen therapeutic effect was done. RESULT: The effective rates was statistically different (chi2 = 8.044, P < 0.01) between group A (60.00%, 36/60) and group B (83.33%, 50/60). There was no statistical difference between two treatment program in mild and the profound deafness patients. The statistical difference could been found between moderate and the severe deafness, the value of chi2 and p were 4.969, 5.560 and 0.040, 0.035, respectively. In group A, the statistical difference could only been found between mild and the profound deafness patients (chi2 = 6.739, P < 0.05). In group B, the statistical difference could been found in mild and the profound deafness, the moderate and the profound deafness, the severe and the profound deafness patients. The value of chi2 were 11.500, 15.058,10.221 and P < 0.01 respectively. The effective rates was no statistical difference in two treatment programs in the upsloping audiogram and the profound deafness. The statistical difference could been found between the downsloping and the flat audiogram, with the value of chi2 and p were 5.144 and 5.969, P < 0.05, respectively. In group A, the statistical difference could been found between the ascending and descending audiogram, the ascending and the flat audiogram,the ascending type and the profound deafness. The value of chi2 were 6.188, 7.247, 8.082 and P < 0.05, respectively. No statistical difference could been found among the other types of audiogram. In group B, no statistical difference could been found among all types of audiogram. CONCLUSION: The effect of hyperbaric oxygen therapy varies with degree of hearing loss and audiogram type. Drug treatment combined with HBOT can promote clinical effect for patients in moderate deafness and severe deafness, the descending and flat type of audiogram.
