We present a rare case of medulloblastoma which presented with unilateral sudden sensorineural hearing loss as an initial symptom. A 19-year-old man was admitted to our hospital with a chief complaint of dizziness and facial numbness on the right side. His illness had begun two years previously with sudden hearing loss on the right side, for which he had been treated as an idiopathic sudden hearing loss. Magnetic resonance imaging demonstrated abnormal signals located mainly in the right middle cerebellar peduncle. We performed partial resection of the tumor by suboccipital craniotomy. The histopathological diagnosis was medulloblastoma. Intrinsic brain tumor is an extremely rare cause of sudden sensorineural hearing loss and is therefore easily overlooked as was in the present case. The present case highlights not only the need to evaluate patients with sudden sensorineural hearing loss by magnetic resonance imaging but also the importance of paying attention to intrinsic lesions involving the brainstem. Although this condition like the presented case might be rare, intrinsic brain tumor should be considered as a potential cause of sudden sensorineural hearing loss, as it may be easily missed leading to a delay in appropriate treatment.

Backgrounds : sudden sensorineural hearing loss is defined as a disease that has abrupt onset of sensorineural hearing loss without definite cause. In some cases, this disease cause tinnitus, vertigo, headache addition to hearing loss. In traditional oriental medicine, sudden sensorineural hearing loss is could be diagnosed as deficiency of Yang-Gi(陽氣). Objects & Methods : This study is clinical observation about three sudden sensorineural hearing loss cases. For diagnosing in these cases, pure tone audiometry was used. For treatment, acupuncture, herbal-medicine and moxibustion therapy were used. Results & Conclusions : as follows. 1. Generally, in this disease, the shorter the whole period from the time that occurs to the time that starts to treat is, the more the results are better. The research shows that short-term case is more efficient than the other long-term two cases in the aspects of symptoms and pure tone audiometry . 2. In making a diagnosis of sudden sensorineural hearing loss and measuring the effect, subjective symptoms generally correspond to the improvement of pure tone audiometry, but not completely. Therefore, in treating patients, the doctor must consider these both aspects and keep the balance.

The aims of this study are to consider auditory physiological characteristics and to confirm audiological evaluation and interpretation in regards to cases of sensorineural hearing loss that observe an abnormal AB gap. Vestibulosaccular hearing occurs when there is an abnormally large air-bone gap (AB gap) in sensorineural hearing loss, also known as pure cochlear conductive hearing loss. Generally, an AB gap is caused by damage to the external and/or middle ear. In conductive hearing loss, loss of air condition hearing occurs due to a loss of resonance in the outer ear and/or impedance mismatching in the middle ear. Most of these types of hearing loss can be treated medically and surgically. However, there is no medical treatment for an AB gap in sensorineural hearing loss and hearing loss can worsen gradually or suddenly. In addition, many studies have reported that head trauma makes hearing loss even more serious. Therefore, in order to differentiate between conductive hearing losses, it is important to check whether or not there is an enlarged vestibular aqueduct by means of temporal bone computerized tomography and/or magnetic resonance imaging.

Objectives : The purpose of this study is to report the case of a bilateral sudden sensorineural hearing loss patient whose hearing had improved by Korean medical treatment combined with threshold sound. Methods : A woman diagnosed with bilateral sudden sensorineural hearing loss has treated with Korean medical interventions(acupuncture combined with electromagnetic stimulation and pharmacoacupuncture) and threshold sound conditioning(TSC) for 20 weeks. Pure tone audiometry(PTA) was performed for the evaluation. Results : The average hearing level has improved from mild to normal level. The level of tinnitus has decreased from VAS 10 to VAS 4. Conclusions : We observed an improvement in a bilateral sudden sensorineural hearing loss patient's hearing and hereby suggest the possibility of Korean medical treatment and TSC's ameliorating effect on sensorineural hearing loss.

Tinnitus is noise from ear or head without any external sound stimulation and can cause hearing difficulties, psychologenic disturbances or many difficulties in everyday life. the etiology has yet been discussed and the management is also very difficult. Sensorineural hearing loss is defined as a sudden hearing impairment which was develope over a period of hours to days. I report one tinnitus case which accompanied with sudden sensorineural hearing loss. In the early and acute stage which judged as Dam-Wha, herbal treatment with Tong-myeong-ri-gi-tang was efficacious on the tinnitus. In the convalescent stage and judged as Sin-heo, herbal treatment with Ja-sin-tong-i-tang was efficacious on the tinnitus that accompanied with sudden sensorineural hearing loss.

Objectives : The purpose of this study was clinical observation about sensorineural hearing loss compare with acupucture treatment and assessments of prognotic factors. Methods : This study was clinical observation about sensorineural hearing loss cases. for diagnosing in these cases, pure tone audiometry was used. The treatment, acupuncture was used. Results : Three patients(37.5%) remarkably improved, one patient(12.5%), slightly improved, four patients(50%), no change. Conclusions : These results suggest that the prognosis by age and initial hearing threshold was significant. The treatment on sensorineural hearing loss considered that bone condution improved.

Background and Objectives: In this study, we compared the outcomes of patients with idiopathic sudden sensorineural hearing loss who underwent steroid treatment with or without hyperbaric oxygen (HBO) therapy and were followed-up in our clinic. Subjects and Methods: Patients were divided into two groups according to their treatment regimen. Steroid group received intravenous 1 mg/kg methylprednisolone which was due to be completed in 2-3 weeks with decreasing doses, and five doses of 0.5 mL intratympanic dexamethasone. Steroid+HBO group received the same steroid treatment with the addition of HBO therapy. The audiologic results of both treatment groups were compared after considering the patients' risk factors. Results: There was no significant difference between the steroid and Steroid+HBO groups in terms of hearing gain and degree of recovery, both at all degrees of hearing loss, and in severe and profound hearing loss. Hearing gain was similar when evaluated by audiogram type and admission time in both treatment groups. Conclusions: We found that the addition of HBO therapy to systemic plus intratympanic steroid treatment did not affect hearing gain at all degrees of hearing loss in this study. Furthermore, audiogram type and admission time did not affect hearing gain between the two groups.

Background noise is one of the major complaints of not only hearing impaired persons but also normal listeners. This paper describes the results of two experiments in which speech recognition performance was determined for listeners with normal hearing and sensorineural hearing loss in noise environment. First, we compared speech enhancement algorithms by evaluation speech recognition ability in various speech-to-noise ratios and types of noise. Next, speech enhancement algorithms by reducing background noise were presented and evaluated to improve speech intelligibility for sensorineural hearing impairment listeners. We tested three noise reduction methods using single-microphone, such as spectrum subtraction and companding, Wiener filter method, and maximum likelihood envelop estimation. Their responses in background noise were investigated and compared with those by the speech enhancement algorithm that presented in this paper. The methods improved speech recognition test score for the sensorineural hearing impaired listeners, but not for normal listeners. The results suggest the speech enhancement algorithm with the loudness compression can improve speech intelligibility for listeners with sensorineural hearing loss.

Back ground & Objectives : Bilateral sudden sensorineural hearing loss(SSNHL) is very rare disease. This is the first case report in the oriental medical literature. This study describes a case of bilateral SSNHL with incomplete recovery. Methods : We treated 1 patient who had SSNHL sequentially in both ears. He received oriental and western medical treatments for more than 2 weeks and measured the hearing recovery. For diagnosis on this case, pure tone audiometry was used. The degree of improvement was evaluated by Siegel's Criteria. Results & Conclusions : This patient discharged without hearing improvement. For bilateral SSNHL patients, the result of treatment is important for their qualities of life. But the recovery rate of hearing in bilateral SSNHL is lower than unilateral SSNHL. The oriental medical therapy had some theraputic effects on SSNHL and the theraputic effects on bilateral SSNHL requires further study.
