192 children with sensorineural deafness were included in this study. The most of children were diagnosed late with ages over 24 months (92%). Only 18% of children were discovered early and instantly examined in otorhinolarygologic facilities, while 72% of children were treated when they were at school ages. Among 99% of children with severe deafness, 68% had deafness due to flare-up of the fire of the liver and gall bladder and 32% of cases with deafness due to insufficiency of the Yin or the liver and kidney. Congenital deafness only accounted for 8% of cases, while the most of cases with deafness were resulted from preventable causes, out of them 28% of cases with deafness related to pregnancy and childbirth and 20% of cases with deafness related to the administration of aminosids

1. Audiometiric examination for 14 cases of retinal pigmentary degeneration revealed a case of conductive deafness, and 4 cases of perceptive hearing disturbances. 2. There were no complaints of subjective hearing disturbances among the cases of perceptive hearing impairments. 3. All the cases of perceptive hearing loss were thought to be due to cochlear lesion according to tone decay tests. 4. There were no cases accompanied by systemic or neuropsychiatric disorders among the 14 cases of retinal pegmentary degeneration. 5. It has been emphasized that pigmentery degeneration of the retina is frequently associated with perceptive hearing disturbances. Genetical and etiological discussions were tried for this association.

Electro-acupuncture was applied for 149 perceptive deaf children. The control group included 43 deaf children treated by speical education method. Results showed that: in the group of electro-acupuncture, 53.3% had got improvement, higher than the group of special education by 23.3%. The improvement rate was higher in mild deaf group, than in severe group. It was also higher in acquired deaf subjects than in congenital subjects. In the deaf caused by “can dom hoa cuong” (aggressive fire of liver and bile), improvement level was higher than the deaf caused by “than am hu” (failure of kidney yinn). The treatment with more courses had got higher improvement than with less courses.

The preoperative hearing status is one of the important factors to determine the method of surgical approach to the vestibular schwannoma. It has been widely recognized that the hearing preservation surgery is not valuable if the patient has no serviceable hearing. The worldwide reported cases of hearing improvement after surgical removal of vestibular schwannoma with profound hearing disturbance are extremely rare, and so far, there have been no domestic cases reported. The authors have experienced a case of significant hearing improvement after surgical removal of vestibular schwannoma with preoperative unilateral total deafness but with normal otoacoustic emission response. We report this case with literature review.
