    BACKGROUND: Tinnitus is a common condition in adults; however, the pathophysiology of tinnitus remains unclear, and no large population-based study has assessed the associated risk factors. The aim of this study was to analyze the prevalence and associated risk factors of tinnitus.

    METHODS: We conducted a cross-sectional study using data from the Korea National Health and Nutrition Examination Survey, with 19,290 participants ranging in age from 20 to 98 years old, between 2009 and 2012. ...

    ObjectivesThe aim of the study is to identify the following associations: (1) severity of obstructive sleep apnea syndrome (OSAS) and laryngopharyngeal reflux (LPR)-related clinical parameters, such as reflux finding score (RFS), reflux symptom index (RSI), and LPR–health-related quality of life (LPR–HRQOL) and (2) complete obstruction on drug-induced sleep endoscopy (DISE) and LPR-related clinical parameters.Materials and methodsSubjects included the OSAS patients without surgery ...

    OBJECTIVES: The objective of our study was to establish whether increased lipid profiles and obesity affect the prevalence and prognosis of sudden sensorineural hearing loss (SSNHL).

    METHODS: This was a case-controlled study with a longitudinal design. According to our criteria, 324 patients with SSNHL were included in this study. To manage potential covariates, 972 subjects with normal hearing from the Korean National Health and Nutrition Examination Survey were matched as control group ...

    The association between idiopathic sudden sensorineural hearing loss (ISSNHL) and the radiologic characteristics of the vertebrobasilar artery is unclear. We hypothesized that the degree and direction of vertebrobasilar artery curvature in the posterior circulation contribute to the occurrence of ISSNHL. We consecutively enrolled patients diagnosed with unilateral ISSNHL in two tertiary hospitals. Magnetic resonance images were performed in all patients to exclude specific causes of ...

    BACKGROUND: Tinnitus in children and adolescents is known to be as common as in adults. However, tinnitus in this young population is often overlooked, and a large population-based study designed to adjust for various risk factors for tinnitus is lacking.

    METHODS: A cross-sectional study was conducted using data from the Korea National Health and Nutrition Examination Survey, with 3047 participants aged 12 to 19 years, from 2008 through 2011. We investigated the tinnitus prevalence by ...

    BACKGROUND: Pneumolabyrinth is a rare inner ear clinical manifestation. To date, only about 50 cases have been reported—all as case reports. Consequently, the rate and clinical characteristics of pneumolabyrinth have not been evaluated.

    METHODS: Of the 38, 568 patients who visited our emergency department for head trauma, 466 underwent temporal bone computed tomography (CT). One hundred seventy-five patients had temporal bone fracture (13 bilateral temporal bone fractures; 188 ears with ...

    CONCLUSION: The elevated neutrophil-to-lymphocyte ratio (NLR) value in children with sudden sensorineural hearing loss (SSNHL) would suggest the inflammatory etiology of pediatric SSNHL. The results of this study may suggest NLR value can be used as a useful indicator, which is associated with the disease severity in pediatric SSNHL.

    OBJECTIVES: This study aimed to elucidate any clues of inflammatory etiology, which might be related with the development of pediatric SSNHL, using ...

    OBJECTIVE: Hyperglycemia is not identified as a significant prognostic factor for idiopathic sudden sensorineural hearing loss in any literature. Therefore, we investigated the prognostic value of hyperglycemia in predicting hearing recovery.

    STUDY DESIGN: A retrospective cohort study.

    SETTING: Tertiary university hospital.

    SUBJECTS AND METHODS: Patients were classified into 3 groups according to their glucose tolerance using the 75-gram oral glucose tolerance test and hemoglobin A1c ...

    We aimed to estimate the effects of various risk factors on hearing level in Korean adults, using data from the Korea National Health and Nutrition Examination Survey. We examined data from 13,369 participants collected between 2009 and 2011. Average hearing thresholds at low (0.5, 1, and 2 kHz) and high frequencies (3, 4, and 6 kHz), were investigated in accordance with various known risk factors via multiple regression analysis featuring complex sampling. We additionally evaluated data ...

    Concha bullosa is a common anatomic variation of the middle turbinate; however, sinusitis secondary to the concha bullosa is rare. A 52-yr-old woman presented with nasal obstruction and posterior nasal drip. Computed tomography and examination of the nasal cavity revealed septal deviation on the left side, and a massive concha bullosa and maxillary sinusitis on the right side. The lateral lamella of the affected turbinate was removed and the inspissated material was drained. ...

    Previous studies have reported that chronic rhinosinusitis (CRS) is closely related to depression. The present study aims to elucidate the association between CRS without nasal polyp and depression using a national sample cohort. Using the national sample cohort from Korean Health Insurance Review and Assessment Service, we matched patients with CRS (n = 21,707) to control participants (n = 86,828), at a ratio of 1:4, according to age, sex, household income, region of residence. The ...

    Clinical studies are reported in which artificial wounds in rat epidermal and dermal tissue have been treated by arrays of sub-500??m diameter, low temperature plasma microjets. Fabricated in Al/nanoporous alumina (Al2O3) by wet chemical and microablation processes, each plasma jet device has a double parabolic (hourglass) structure, and arrays as large as 6?????6 devices with 500??m diameter apertures have been tested to date. Treatment of 1?cm2 acute epidermal wounds for 20?40?s daily ...

    OBJECTIVES: The silk patch is a thin transparent patch that is produced from silk fibroin. In this study, we investigated the treatment effects of the silk patch in patients with traumatic tympanic membrane perforation (TTMP).

    METHODS: The closure rate, otorrhea rate, and closure time in all patients and the closure time in successful patients were compared between the paper patch and silk patch groups.

    RESULTS: Demographic data (gender, site, age, traumatic duration, preoperative ...

    Scaffolds derived from silk fibroin are widely used as biomaterials. In this report, a new all-aqueous process is described for the production of three-dimensional porous silk fibroin scaffolds. The process uses poly(ethylene oxide), and a novel salt leaching technique. The fabricated scaffolds were tested for their physical characteristics. The measured scaffold porosity ranged from approximately 67.95% to 84.7%. Swelling studies demonstrated that the fabricated scaffolds had fair ...
