There have been very few studies on the prognosis of postviral olfactory dysfunction. The aim study was to evaluate its long-term and factors influencing prognosis.This included patients who were diagnosed with dysfunction at least one year ago in a Smell Taste Clinic whose telephone interviews available. Their medical records reviewed, they asked score their subjective function 100-point scale by interview.A total 63 20 normal controls without nasal pathology included. mean age 49.5 years,...
Population-based studies for olfactory dysfunction are lacking. The aim of this study is to evaluate the prevalence subjective and its risk factors in Korean general population.The data were obtained from 2009 Korea National Health Nutrition Examination Survey (KNHANES), which was a cross-sectional survey non-institutionalized population all around country (n = 10,533). All interviewees underwent medical interviews, physical examinations, endoscopic examination blood/urine tests. Whether...
Background There has been no nationwide epidemiological investigation of allergic rhinitis (AR) that was diagnosed by both questionnaires and laboratory tests in Korea. This study investigated the prevalence, risk factors, comorbidities AR South Methods The Korean National Health Nutritional Examination Survey examined a representative sample population. A total 2305 participants underwent immunoradiometric assay for specific IgE antibodies against common indoor allergens. Healthy, atopy...
To evaluate retrospectively the efficacy of mandibular advancement device (MAD) in patients with obstructive sleep apnea terms positional dependency.Retrospective analysis.Academic tertiary referral center.One hundred treated MAD at Department Otorhinolaryngology clinic were included from January 1, 2005, through December 31, 2010.All underwent nocturnal full-night polysomnography before and least 3 months after intraoral application.Treatment results prognostic factors deciding success...
Hearing aids (HAs) with frequency lowering have been used for high-frequency hearing loss (HFHL), but their effects on tinnitus relief not studied extensively. This randomized double-blind trial was performed to investigate and compare suppression of conventional type HAs frequency-lowering in patients HFHL.A total 114 were into three groups: HA using wide dynamic range compression, translation, linear transposition. Participants wore 3 months then discontinued use. The final evaluation at...
Currently, epidemiological data on allergic rhinitis collected through the skin prick test are scarce. Moreover, relationship of age and sex to is not comprehensively understood. This study aimed characterize associated clinical manifestations by sex.We retrospectively investigated from 2883 patients who visited a single university hospital for symptoms between January 2003 December 2014. Of these patients, 1964 underwent with 11 standardized allergen extracts completed nasal symptom...
Several studies have reported that chronic rhinosinusitis (CRS) increases the risk of stroke. The aim this study is to elucidate putative association between CRS and stroke (ischemic or hemorrhagic) using large population-based national health insurance data.Using cohort from Korean Health Insurance Review Assessment Service, patients (n = 22,959) control participants 91,836) were selected matched at a rate 1:4 (age, sex, income, region, hypertension, diabetes, dyslipidemia). A...
Several studies have shown a relationship between cigarette smoking and general diseases of the nose in large Asian population. The current study was conducted to better understand effect smoke exposure on rhinologic Koreans.Data were obtained from 2008-2011 Korea National Health Nutrition Examination Survey, cross-sectional survey noninstitutionalized population Korea. Of 37,753 people surveyed, 11,589 adult participants had completed questionnaires symptoms behaviors, undergone nasal...
Although nasal polyps (NPs) are thought to be a common otorhinolaryngologic disease, there have been few population-based epidemiologic studies on the prevalence of NPs. The aim this study is evaluate NPs and risk factors in general Korean population.The data were obtained from Korea National Health Nutrition Examination Survey (KNHANES) (2009-2011), which was cross-sectional survey noninstitutionalized populations all around country (n = 28,009). Among them, 19,152 participants (age more...
The definition and the criteria for successful treatment of obstructive sleep apnea vary, depending on study. This study aimed to compare different success non-continuous positive airway pressure (non-CPAP) in terms quality by using cardiopulmonary coupling.We included 98 patients who had been treated with surgery or a mandibular advancement device at our clinic from January 2011 March 2013. failure groups were divided 6 that have used literature. validity each was evaluated coupling-based...
Objective: Anxiety and depression are psychiatric comorbidities potentially associated with dizziness migraine, which can influence disease state, prognosis, clinical outcomes. Vestibular migraine (VM) is a that causes repeated vestibular symptoms in people history of migraines. We investigated the prevalence contributing factors anxiety patients VM. Methods: A total 74 VM were enrolled this study. All underwent pure-tone audiometry, examination spontaneous nystagmus, Dix–Hallpike maneuver...
Background/Objective There have been several operative techniques for adenoidectomy and their efficacy morbidity are different according to the technique. This prospective multicenter study was aimed compare of coblation (CA) with those power-assisted adenoidectomy. Study Design Prospective multi-institutional study. Methods Children who underwent CA, cauterization (PAA+C) or without (PAA-C) due adenoid hypertrophy were enrolled from 13 hospitals between July 2013 June 2014. Mean operation...
Abstract A mandibular advancement device (MAD) is recommended as an alternative therapy for obstructive sleep apnea (OSA), which effectively reduces the collapsibility of upper airway during by advancing mandible. However, effects MAD on cardiac autonomic modulation remain unclear. We evaluated nocturnal heart rate variability (HRV) in OSA. Anthropometric data, questionnaire results, and HRV parameters (evaluated using time domain frequency methods) 58 adult patients with OSA treated were...
The association between daytime/nighttime heart rate variability (HRV) and the apnea-hypopnea index (AHI) remains unclear. We sought a relationship AHI daytime-to-nighttime HRV ratio as measured by 24-hour Holter monitoring in patients with obstructive sleep apnea.We prospectively enrolled 66 who visited our clinic complaining of habitual snoring or apnea. All underwent (to measure HRV) combined full-night polysomnography. Sixty-two met enrollment criteria. evaluated associations frequency...
Conclusion: Acoustic characteristics of snoring sound, such as pitch and formant, differed according to the site upper airway obstruction determined by sleep videofluoroscopy (SVF). Snoring sound analysis can complement determination in apnea patients. Objectives: The aim this study was evaluate acoustic SVF. Methods: Ninety patients who underwent simultaneous recording during SVF were included study. parameters (min, mean, max) formant (1,2) analyzed. Site classified anatomic structure...
Objectives The purpose of this study is to evaluate the risk retropharyngeal and parapharyngeal abscesses (deep neck infection) after tonsillectomy in Koreans using national cohort data. Methods Using from Korean Health Insurance Review Assessment Service, participants who had undergone a (5,299) control (21,196) were selected matched 1:4 (for age, sex, income, region residence, pre-operative upper respiratory infection visits). Cox-proportional hazard model was used. A crude an adjusted for...
Abstract Purpose Obstructive sleep apnea is a known risk factor for the progression of chronic kidney disease. To find early signs in subjects with obstructive apnea., we assessed diurnal variation biomarkers. Methods A prospective observational study was conducted at Kangwon National University Hospital, Chuncheon, South Korea. All participants underwent in-laboratory polysomnography and phlebotomy evening before morning after polysomnography. Kidney biomarkers, including serum creatinine,...
Background Nasal septal deviation (NSD) is a very common deformity. Because it may induce chronic upper airway obstruction in the nose, clinicians encounter some patients who have concerns about whether this can be risk factor for general health. However, influence of NSD on health has rarely been studied. Objective To determine associations between NSD, especially with nasal obstructive symptom, and problems an adult Korean population. Methods This nationwide study analyzed data from Korea...
