Background and Objectives: The speech-in-noise test is typically performed using an audiometer. The results of the digit-in-noise recognition (DIN) test may be influenced by the flat frequency response of free-field audiometry and frequency of the hearing aid fit based on fitting rationale. This study aims to investigate the DIN test in unaided and aided conditions. Subjects and Methods: Thirty four adults with moderate and severe sensorineural hearing loss (SNHL) participated in the study. The signal-to-noise ratio (SNR) for 50% of the DIN test was obtained in the following two conditions: 1) the unaided condition, performed using an audiometer in a free field; and 2) aided condition, performed using a hearing aid with an unvented individual earmold that was fitted based on NAL-NL2. Results: There was a statistically significant elevation in the mean SNR for the severe SNHL group in both test conditions when compared with that of the moderate SNHL group. In both groups, the SNR for the aided condition was significantly lower than that of the unaided condition. Conclusions: Speech recognition in hearing-impaired patients can be realized by fitting hearing aids based on evidence-based fitting rationale rather than by measuring it using free-field audiometry measurement that is utilized in a routine clinic setup.

Objectives : The purpose of this study is to report the effect of east-west medical combined treatment of sudden sensorineural hearing loss(SSNHL) through cooperation in a hospital. Methods : We treated three patients diagnosed as SSNHL by combination of herbal medicine, acupuncture, pharmoacupuncture, moxibustion, cupping, laser therapy and conventional medications. We evaluated the results of this treatment with pure tone audiometry, word recognition score(WRS), the changes in distortion product otoacoustic emissions(DPOAE) and visual analogue scale. Results : One of them showed a meaningful improvement in the hearing level of the low frequency region. The others showed 'Complete recovery' in pure tone audiometry and WRS. The subjective symptoms including tinnitus and ear fullness improved in three patients. Conclusion : This study suggests that east-west medical combined treatment is effective on SSNHL patients.

The purpose of this study is to report a clinical progress of sudden hearing loss through korean medicine. Between 26th Mar. 2014 and 19th Apr. 2014, she was treated with Chuna manual therapy every day and observed by Pure Tone Audiometry (before and after) and visual analogue pain scale (VAS). A patient was diagnosed with sudden hearing loss on 23th Dec. 2013 in Severance Hospital, she had sudden hearing loss on left side. She had 19 times treatments. At the first of treatment, her audibility was 20 dB on right side, 74 dB on left side and she had tinitus and ear fullness (VAS 8 / VAS 9). At the middle of treatment (2nd Apr. 2014), symptoms of tinitus and ear fullness started improving. State was tinitus VAS 6, ear fullness VAS 6. At the end of treatment (21th Apr. 2014), state was tinitus VAS 4, ear fullness VAS 4, and recorded 35 dB on right side, 80 dB on left side in pure tone audiometry. Chuna manual therapy is estimated to be good for sudden hearing loss especially on tinitus and ear fullness. More cases are required to develop treatment of sudden hearing loss.

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.

Cortical deafness is a clinical rarity whereby a patient is unresponsive to all types of sounds despite the preserved integrity of the peripheral hearing organs. In this study, we present a patient who suddenly lost his hearing following ischaemic infarcts in both temporal lobes with no other neurological deficits. The CT confirmed damage to the primary auditory cortex (Heschl's gyrus) of both hemispheres. Initially, the patient was unresponsive to all sounds, however, he regained some of the auditory abilities during 10 months follow up. Pure tone threshold improvement from complete deafness to the level of moderate hearing loss in the right ear and severe in the left was observed in pure tone audiometry. Otoacoustic emissions, auditory brainstem responses, and acoustic reflex findings showed normal results. The middle and late latency potential results confirmed objectively the improvement of the patient's hearing, however, after 10 months still, they were somewhat compromised on both sides. In speech audiometry, there was no comprehension of spoken words neither at 3 nor at 10 months. The absent mismatch negativity confirmed above mentioned comprehension deficit. The extensive auditory electrophysiological testing presented in this study contributes to the understanding of the neural and functional changes in cortical deafness. It presents the evolution of changes after ischaemic cerebrovascular event expressed as auditory evoked potentials starting from short through middle and long latency and ending with event-related potentials and supported by neuroimaging.
