Sudden sensorineural hearing loss (SSNHL) is a common disorder; however, sequential, bilateral presentation of the disease is rarer than unilateral presentation. Clinical otologists usually focus on treating the side with impaired hearing when patients first present with unilateral SSNHL, and therefore, may not warn patients of the possibility of subsequent hearing impairment in the contralateral ear. Furthermore, it is professionally discouraging when a patient presents with profound, sequential SSNHL after initial treatment. This may adversely impact the doctor-patient relationship, even if the patient is offered the best possible care from their first visit. Herein, we report the case of a patient with profound, idiopathic, bilateral SSNHL with a time interval of 37 days between involvement of both ears. Even though high-dose steroids were administered intraorally and intratympanically, the patient's hearing was not restored, and the patient eventually required bilateral cochlear implant surgery. Our report demonstrates that sequential, profound, bilateral SSNHL may manifest without any specific signs.

Preschool children to do production and acquisition of phonological system from birth to 8 years of age. If a child has hearing loss, he/she has a lot of difficulties to hear sound. The problem of auditory perception can causes limited speech acquisition, delayed language development, and communication disorders. It also affects learning, social and emotional development. Early detection and diagnosis of hearing loss are important for intervention. However, it may be difficult to detect if the degree of hearing loss are slight and/or it appears only on some frequencies. In cases of these kinds of hearing losses, it is often difficult to provide aural intervention. The goal of this study is to discuss the interpretation of audiological evaluation in case of mild-to-moderately severe asymmetric ski-slop sensorineural hearing loss, analyze communication problems, and concerning about audiological, and speech-language pathological rehabilitation.

Background: Idiopathic sudden sensorineural hearing loss(ISSHL) has been generally defined as an abrupt loss of auditory acuity without precipitating factors. Since ISSHL was first described as a disease entity, numerous reports assessing a variety of treatment regimens have been published. But its etiology, pathogenesis, treatment, and prognosis are controversial at the present time. Stellate ganglion block(SGB) has been used for the treatment of ISSHL by vasodilatation and increased blood flow to the inner ear. Methods: We reviewed the records of 152 patients to investigate the efficacy of SGB for ISSHL. The control group was managed with medications such as hypaque, heparin, steroid, nicotinic acid, and vitamins. The SGB group was managed with SGB and the same medications. SGB was performed with 8 ml of 1.0% mepivacaine. The efficacy of treatment was evaluated by pure-tone average following therapy. The recovery of hearing was defined as Siegel's criteria I, II, or III. Results: The recovery rate of the SGB group was higher than that of the control group(61.5 vs. 42.9%, p<0.05). The recovery rate was higher in patients who were treated early, within 7 days from the onset of symptoms, especially in the SGB group(79.7%). And in the case that initial hearing loss was severe (>70dB), the SGB group had a higher recovery rate(64.2%) than the control group(42.5%). Conclusions: SGB is thought to be a useful therapy for ISSHL, especially in the patients who were treated soon after onset or whose initial hearing loss was severe.

Objectives : The aim of this report was to investigate the effects of Korean medical treatment on facial nerve paralysis with sensorineural hearing loss and tinnitus caused by traumatic temporal bone fracture. Methods : We treated a patient with acupuncture, herbal medicine and physiotherapy. The effect of these treatments was evaluated by House-Brackmann facial grading scale, Yanagihara's unweighted grading system and by Digital Infrared Thermographic Image. Results : After 21 days of Korean medical treatment, House-Brackmann facial grading scale changed from III to II and Yanagihara's unweighted grading score increased from 14 to 27. Digital Infrared Thermographic Image also improved. Conclusions : These results suggest that Korean medical treatments were effective in treating facial nerve paralysis with sensorineural hearing loss and tinnitus caused by traumatic temporal bone fracture. We hope that a more efficient application of this treatment will be the result of clinical data accumulated in future studies.

Objectives: Sudden sensorineural hearing loss (SSHL) is considered an ENT emergency. Despite being a well-recognized condition, SSHL remains one of the most controversial issues in otology. Nowadays, more and more patients have an interest in Oriental medicine for treatment of SSHL. So, to ascertain the therapeutic effect of Oriental Medicine on SSHL, nineteen cases of SSHL patients who had taken Oriental medical therapy in Kyung Hee Oriental Medical Hospital were examined and analyzed. Methods: Nineteen patients who received over 10 times acupuncture therapy and a minimum 2 weeks of herbal medicine from Sep. 1, 2007 to Aug. 31, 2008 were examined and analyzed. The patients who were in the categories below were excluded: - within 7 days after onset - didn't fulfill 10 times acupuncture therapy - failed to recheck hearing outcome after treatment - less than 30dB at mean dB from 250Hz${\sim}$4000Hz. Results: The patients consisted of 12 men and 7 women with a mean age of 45.63 years (19${\sim}$76). Before treatment, 17 patients had tinnitus, 16 patients had pressure in the ear and 6 patients had dizziness, and mean dB of all patients was 66.89 dB. After treatment, 9 patients still had tinnitus, 4 patients felt pressure in the ear and 2 patents felt dizziness, and mean dB of all patients was 54.57dB. After treatment, 9 patients showed effectiveness in improving both hearing level and speech discrimination, 6 patients showed effectiveness only on speech discrimination and 4 patients showed no therapeutic effect. Conclusion: Oriental medical therapy had some therapeutic effects on SSHL even it was started 7 days after onset of the disease.

Purpose: Kawasaki disease involves acute febrile systemic vasculitis that can cause a variety of symptoms by affecting various organs. Here, we aimed to evaluate the prevalence, causes, and prognosis of sensorineural hearing loss (SNHL) occurring in children with Kawasaki disease. Methods: Patients who were diagnosed with Kawasaki disease and received inpatient treatment in the Pediatrics Department at one of three university hospitals in Daegu city from February 2012 to September 2012 were enrolled in the study. The clinical features, hematological results, echocardiography results, audiometry results, and aspirin and salicylic acid serum levels of the patients were evaluated. Results: Of the 59 children enrolled in the study, three showed mild bilateral SNHL on audiometry tests conducted after 48 hours of defervescence; these patients demonstrated normal patterns of recovery on follow-up tests 8 weeks later. Aspirin serum levels were significantly higher in the SNHL group after 48 hours of afebrile condition with high dose aspirin intake (P=0.034). However, no significant differences were found in other laboratory tests or for fever duration (P>0.05). Upon echocardiography, coronary artery abnormality was observed in 9 cases, but none of these patients showed hearing loss. Conclusion: The results indicate that SNHL in children with Kawasaki disease might occur during treatment of the acute phase; this SNHL usually involves mild bilateral hearing loss and recovers naturally. However, this study suggests that determination of the causes and clinical implications of hearing loss in Kawasaki disease requires long-term follow-up studies with more cases.

Idiopathic sudden sensorineural hearing loss(SNHL) is defined as a sensorineural hearing loss which develops over a period of hours or few days without a definitive causes. The etiology, prognosis, and treatment of SNHL are uncertain. We reviewed records of 76 patients to investigate the efficacy of the stellate ganglion block(SGB)in SNHL. The control group(40 patients) was managed with the medication such as hypaque, heparin, steroid, nicotinic acid, and vitamine. The SGB group(27 patients) was managed with the same medication and SGB (1~2 times/day). The efficacy of treatment was evaluated by mean dB of 500, 1000, 2000 Hz on follow up pure tone audiogram. Recovery rate above 15dB was not different between SGB and the control group (52.4 v.s. 52.0%), though SGB group has much poor prognostic factors. Recovery rate was higher in a case that was treated early. Especially, the recovery rate was 100% when SGB begins within 2 weeks from the onset. Headache and profound type of audiogram were poor prognostic factors. In conclusion, SGB within 2 weeks from the onset is recommanded to improve the recovery rate.

In this Paper. we Presents subband design techniques of a compensating filter and adaptive feedback canceller for the digital hearing aid. The sensorineural hearing loss has a hearing threshold that shows a nonlinear characteristic in frequency domain. and its compensation suffers from an echo that produced by an undesired time varying feedback path. Therefore. the digital hearing aid requires the compensator that can adjust gains nonlinearly in frequency bands and eliminate the echo rapidly In the Proposed digital hearing aid. the compensating filter is designed by the adaptive system identification method in subband structure, and the adaptive feedback canceller is designed by the subband affine projection algorithm. The designed compensation filter can control the nonlinear gain in each subband respectively, therefore precise compensation is possible. And the feedback canceller using the subband adaptive filter achieves fast convergence rate. The Performances of the Proposed method are verified by computer simulations as comparing with the behaviors of the previous trials.

The ichthyosiform dermatosis is consisted of a heterogenous group of hereditary disorders. Authors report a case of 26 year old female patient who has congenital ichthyosiform dermatosis associated with sensorineural hearing loss, neovascularization of cornea, partial alopecia and abnormalities of nails and teeth. The audiological findings of this patient were as follows: 1. Bilateral severe sensorineural hearing loss. 2. SISI scores: 100% at 1, 000 Hz and 4, 000 Hz on both ear. 3. Tone decay test: 25 dB decay at 1, 000 Hz and 4, 000 Hz respectively on both ear. 4. SRTs : 85 dB on both ear. 5. Speech discrimination scores : 80% at 95 dB hearing level(MCL) on both ear. With above results, cochlear lesion is suspected in this syndrome.

Purpose: Alport syndrome (AS) is one of the most common inherited renal diseases caused due to mutations of genes encoding specific proteins of the type IV collagen family, and its major clinical manifestations include progressive renal failure, sensorineural deafness, and ocular abnormalities. We investigated the clinical characteristics and long-term prognosis of AS in Korean pediatric and adult populations. Methods: We conducted a retrospective review of medical records of 33 children and adults who had been diagnosed or treated with AS from 1985 to 2019. Results: The mean age of the 33 patients diagnosed with AS was 16.2±13.6 years, and the male-to-female ratio was 2:1. At the first visit, recurrent gross hematuria was the most common initial symptom. In 10 of 33 patients (30.3%), sensorineural hearing loss (SNHL) was diagnosed, but none had ophthalmic problems. Moreover, 11 of 33 patients (33.3%) had advanced to end-stage renal disease (ESRD), and a significant difference was observed in the age of the patients who progressed to ESRD based on the presence or absence of SNHL (P=0.035). Conclusion: SNHL in AS can be an important prognostic factor for long-term deterioration of renal function. Further investigation is required to confirm the clinical course and the genetic characteristics of AS in Korea through prospective national cohort studies.
