Objectives : The purpose of this study is to report the Korean medical treatment on sudden sensorineural hearing loss(SSNHL). Methods : The patient who has been diagnosed SSNHL had symptoms with hearing loss, tinnitus, and aural fullness. The patient was received outpatient to Dunsan oriental hospital for 3 months and was treated with oriental medicine(acupuncture, herbal-medicine, converting of Hominis placenta, warm needling and vapor treatment). Two approaches were used in order to evaluate the effect of the treatment. The hearing recovery was measured with pure tone audiometry, and the decrease of tinnitus and aural fullness was identified by patient's subjective expression. Results : The patient has his hearing restored fully and the symptoms of SSNHL accompanied with adjunctive symptoms including tinnitus and aural fullness were improved.Conclusions : This study shows that the Korean medical treatment effects on the SSNHL.

1. 청신경 종양 진단의 표준 검사는 두부 가돌리늄 조영 증강 자기 공명 영상 촬영이며, 경제적 문제 등으로 조영 증강 자기 공명 영상 촬영이 어려울 경우에는 청성 뇌간 반응(auditory brainstem response) 검사를 시행할 수 있다. 2. 특발성 돌발성 난청으로 진단 받은 후, 한의 의료기관에 내원한 환자에서도 기존 검사결과를 검토하여 후미로성 질환을 배제한 후 치료를 시작해야한다. 3. 비조영 증강 자기 공명 영상 촬영을 통해 후미로성 질환을 배제한 환자에서도 임상적으로 후미로성 질환이 의심되는 경우에는 표준 검사인 가돌리늄 조영 증강 자기 공명 영상 재촬영을 통해 청신경종을 감별하는 것이 바람직하다. 4. 청신경 종양에서 한방 치료를 표준 치료와 병행하여 제반 증상에 대한 관리를 기대해 볼 수 있다.

Objectives : The purpose of this study is to report three cases of Korean medical treatment for sudden sensorineural hearing loss(SSHL). Methods : This study conducted with three sensorineural hearing loss patients who hospitalized in Ophthalmology, Otolaryngology & Dermatology Clinic of Korean Medical Hospital. Three patients were treated with herbal medicine(Sunkihwalhyeol-tang, Ikgibohyeol-tang, Gongjindan) and acupuncture. After treatment, we evaluated Siegel's Criteria with pure tone audiometry and subjective symptoms alteration. Results : All three patients were completely recovery about Siegel's Criteria and improved subjective symptoms after treatment. Conclusions : This study suggests that Korean medical treatment may be effective about SSHL.

Hearing aids play an very important role in aural rehabilitation for hearing impaired person who could not be medically treated. Especially, hearing aids with dynamic range compression (level dependent frequency response: LDFR) method concentrated dynamic output range of receiver into the narrowing dynamic range of sensorineural hearing impaired person. Thus, if aided hearing threshold level is improved and uncomfortable loudness level rises, then the users of hearing aids are favored with extended dynamic range. This study aims to evaluate audiological benefits in dynamic range compression hearing aids. To achieve this, pure tone and speech audiometry were examined to 15 children and 3 adults with narrow dynamic range moderate-to-severe binaural sensorineural hearing loss.

Objectives : The purpose of this study is to analyze outpatients who visited for treatment for sudden sensorineural hearing loss in ophthalmology & otolaryngology & dermatology clinic of Daejeon Korean medical hospital from January 1st, 2013 to December 31th, 2021. Methods : We retrospectively analyzed outpatients who visited for treatment for sudden sensorineural hearing loss in ophthalmology & otolaryngology & dermatology clinic of Daejeon Korean medical hospital from January 1st, 2013 to December 31th, 2021. according to year, season, gender, age, clinical symptoms, number of visits and initial degree of hearing loss. The statistical analysis performed using IBM SPSS 25.0 for Windows. Results : The results of analyzing the medical records of 194 patients are as follows. 1. The number of patients showed a gradual increase from 2014 to 2021 and spring was highest in season. Acc ording to gender, women visited more than men and the age group that visited the most was middle-aged, including 40s and 50s. 2. Patients experienced 13 symptoms and the average number was 4.06. In the analysis of the major symptoms according to gender, hyperacusis and headache were found to be more common in female. 3. The average of initial hearing loss was 52.54dB and was higher in male. The loss was relatively higher in 60s or older than in the younger age group. Conclusions : If treatment and management methods that reflect these symptoms are developed, it is thought that it will greatly helpful to improve the quality of life of patients with sudden hearing loss.

Objectives : The purpose of this study is to report the case of a presbycusis patient whose hearing had improved. Methods : A 81-year-old male diagnosed with presbycusis were treated with Korean medical interventions (acupuncture combined with electromagnetic stimulation and pharmacoacupuncture) and Threshold sound conditioning(TSC) for 3 months. Pure tone audiometry(PTA) was performed for the evaluation. Results : The patient's hearing was improved from moderate to mild level according to the Classification of Hearing Loss(International Organization for Standardization, 1969). The average hearing were improved from 40.5 dB to 32.7dB on the left side, 46.9dB to 34.1dB on the right side. Conclusions : We observed an improvement in a presbycusis patient's hearing and hereby suggest the possibility of Korean medical treatment and TSC's ameliorating effect on sensorineural hearing loss as well as prebyscusis.

Objective : The purpose of this study is to know the effect of Korean medical treatments on sudden sensorineural hearing loss(SSNHL) without systemic or intratympanic steroid treatments.Method : We conducted retrospective review who was diagnosed as SSNHL and treated with Korean medicine in Dept. of Otolaryngology Kyung Hee University Hospital at Gangdong. There were two patients with SSNHL who refused to be treated with western medicine and were treated with Korean medicine including acupuncture, moxibustion, and herbal medicine.Result : One patient recovered completely after eight days of admission, and another patient partial recovered during 30 days through Korean medical treatments.Conclusion : Through these studies, SSNHL is expected to treated more effectively by conventional Korean medical treatments than corticosteroid treatments alone. But the additional study is needed to reveal the exact effects of Korean medical treatments.

Objectives : Sudden sensorineural hearing loss(SSNHL) is defined as an unexplainable decline in hearing which o㏄urs within a short period of time. This study describes a case of SSNHL accompanied by many unfavourable prognosis factors including severe vertigo. Methods : We treated 1 SSNHL patient who had many unfavourable prognosis factors including severe vertigo. After Korean medical treatment for 23 days, we measured the hearing recovery and decrease of vertigo. For diagnosis, pure tone audiometry was done. The degree of improvement was evaluated by Siegel's Criteria. Decrease of vertigo was assessed by Vertigo Scale. Results & Conclusions : The pure tone 5 frequency(0.25, 0.5, 1, 2, $4_{KHz}$) average improved by 25dB(slightly recovered). Vertigo score decreased from 4 to 1. We may expect that the Korean medical therapy improves the hearing recovery in the SSNHL patients who have unfavourable prognosis factors such as vertigo.

4년령의 암컷 보더 콜리가 청각장애 평가를 위해 내원하였다. 청력 소실의 원인을 확인하기 위해 임상 검사, 신경계 검사, 검이경, 자기 공명 검사법이 실시되었지만, 특별한 이상을 확인할 수 없었다. 청력 소실을 평가하기 위해 뇌간 청각유발전위 검사가 실시되었고, 양측성 감각신경성난청을 확인하였다. 여러 검사와 병력 확인을 통해 후천적 청력 소실의 가능한 원인들을 배제하여 유전성의 양측 후발성 감각신경성난청으로 잠정 진단하였다. 이 보고는 개에서도 사람에서 보고된 유전성의 후발성 감각신경성난청이 있을 수 있다는 것을 제안한다.

본 논문에서는 청각 장애인의 보다 향상된 보청 환경을 조성하고자 청각손실을 심리음향 모델을 적용하여 감음 신경성 난청을 보정하는 알고리즘을 제안한다. 제안한 알고리즘에서는 난청의 유형은 내이에서부터 중추 뇌에 걸친 감음계와 신경계의 장애에서 비롯되는 감음신경성 난청(sensorineural hearing loss)으로 주파수 영역상에서 MTH(minimum hearing threshold)가 균일하지 않게 상승하게되어 가청영역이 좁아지는 문제점을 해결하기 위한 방법으로 각각의 주파수 밴드마다 멀티밴드 압축 알고리즘을 적용하였다. 그러나 이 경우 각각의 주파수 밴드에 따른 서로 다른 가청 영역의 영향에 의한 변형된 스펙트럼 모양으로 인해 spectral contrast reduction과 변형된 마스킹 특성으로 인해 음성 변별력에 제한을 가하게 된다. 이것은 주변 주파수 성분들에 의한 마스킹 효과에 의한 것으로, 신호에 대한 난청인이 느끼는 지각 영역(perceptual domain)에서의 해석과 심리음향 모델 파라미터를 통한 보청기의 개발이 이루어져야 하며, 본 논문에서 그 알고리즘을 적용하였다.
