Cluster analyses on inflammatory markers of chronic rhinosinusitis (CRS) in Asians from multicenter data are lacking. This study aimed to identify the endotypes CRS Koreans and evaluate relationship between clinical parameters.Nasal tissues were obtained patients with controls who underwent surgery. The investigated by measuring interleukin (IL)-5, interferon (IFN)-γ, IL-17A, IL-22, IL-1β, IL-6, IL-8, matrix metalloproteinase-9, eotaxin-3, eosinophil cationic protein, myeloperoxidase (MPO),...
The purpose of this study was to identify delayed auditory maturation and the fate premature infants who failed newborn hearing screening (NHS) in neonatal intensive care unit.A total 1375 neonates underwent NHS using transient evoked otoacoustic emission (TEOAE) a tertiary hospital between 2007 2010 according Joint Committee on Infant Hearing guidelines. In addition, structured telephone survey given caregivers were lost follow-up NHS. Auditory steady-state response (ASSR) threshold change...
Continuous positive airway pressure treatment aggravates obstruction in patients with epiglottis collapse.In these patients, partial epiglottectomy can resolve collapse by excision of the obstructed epiglottis.However, epiglottic usually have simultaneous obstructions on multiple levels, such as soft palate, base tongue, etc.Therefore, sleep apnea cannot be controlled merely resolving collapse.The use additional continuous after is considered essential.However, no studies yet evaluated...
Purpose Head rotation is thought to have an effect on obstructive sleep apnea (OSA) severity. However, keeping the head rotated fully during difficult maintain, and of not same in all OSA patients. Thus, this study aimed identify whether less has airway patency determine responder characteristics maneuver (HRM). Methods We recruited 221 patients who underwent overnight polysomnography drug-induced endoscopy (DISE) a tertiary hospital from June 2019 July 2020. Airway site collapse were...
Rationale: The anatomic orientation of the epiglottis is such that it points in opposite direction to inspiratory flow, thereby potentially making positive airway pressure (PAP) treatment challenging patients with epiglottic collapse. However, no previous studies have analyzed PAP adherence these patients. Objectives: This study aimed analyze autotitrating (APAP) Methods: We performed an age- and sex-matched case-control study. On basis their overnight level-I polysomnogram, were prescribed...
Methicillin-resistant staphylococcus aureus is an emerging problem for the treatment of chronic suppurative otitis media, and also pediatric tympanostomy tube otorrhea. To date, there are no effective topical antibiotic drugs to treat methicillin-resistant otorrhea.In this study, we evaluated ototoxicity KR-12-a2 solution on cochlea when it applied topically in middle ear guinea pigs.The antimicrobial activity against strains was examined by using inhibition zone test. Topical application...
Background In this study we evaluated the effects of inferior turbinate radiofrequency ablation (RFA), performed after septoplasty, on patients with allergic rhinitis (AR) symptoms. Methods This was a prospective, randomized, controlled involving 60 both deviated nasal septum (DNS) and AR. Those who underwent septoplasty/sham surgery constituted Septo‐Sham group those septoplasty/RFA formed Septo‐RFA group. Demographic factors, pre‐ postoperative symptom scores for (SFARs), Nasal Obstruction...
<b><i>Objectives:</i></b> This study aimed to evaluate potential therapeutic effect of <i>Metagonimus yokogawai</i> on the OVA-induced allergic rhinitis model. <b><i>Methods:</i></b> OVA-sensitized mice were used assess extract protein <i>M. (My-TP). My-TP was administrated via intralymphatic route cervical lymph nodes. The frequencies sneezing or nasal rubbing recorded. Histopathologic evaluation performed for eosinophil...
Epistaxis is one of the common causes emergency department (ED) visits. However, most cases are not severe and undergo an unnecessary medical evaluation, especially in non-traumatic epistaxis. This study investigated how many patients require a definite observational unit (DOU) what factors associated with DOU among epistaxis patients. retrospective included 1197 who visited ED from January 2016 to December 2020. Multiple logistic regression analysis was performed evaluate association...

Laryngeal foreign body can be a life-threatening emergency. Respiratory distress, aphonia, and cyanosis may occur in quick succession. However, case of non-obstructive laryngeal body, symptoms indolent, but the hazardous nevertheless put patient danger. To prevent consequences, early detection based on is imperative. This case, which presented with usual anterior neck pain throat discomfort without respiratory an unusual site finally turned out to impacted fish bone subglottis. Key words:...
Background and Objectives Although canal wall up mastoidectomy (CWUM) has been performed frequently as a treatment for chronic otitis media (COM), the necessity of CWUM non-cholesteatomatous COM (NCCOM) is still controversial. Since elderly people often have systemic problems, there high likelihood side effects after general anesthesia, so it important to judge mastoidectomy. The purpose this study was investigate effect NCCOM in patients over 65 years age. Subjects Method Forty-two cases...
Background and Objectives A lack of investigators for polysomnography has risen due to increased demand since health insurance started cover the cost test. We examined reliability automated scoring polysomnography, which been deployed improve this imbalance.Subjects Method analyzed data 20 patients who underwent level 1 from April July 27, 2019. The software Noxturnal (Nox Medical) was used Polysomnography data. Each polysomnographic scored both by system a skilled technician.Results Twenty...
Hearing loss in older people can cause communication impairments, decreased quality of life, social isolation, depression, and dementia. Cochlear implant surgery is an effective treatment for patients with hearing who cannot achieve satisfactory audiologic outcomes aids. However, have increased risk heart disease often take medications that affect rhythm. Herein, we report a case 80-year-old woman underwent cardioversion at 50J after cochlear surgery. Electrical impedance before showed only...
Foreign body (FB) aspiration is one of the causes respiratory distress in infants an extremely dangerous and potentially life-threatening event. The diagnosis FB difficult because signs symptoms vary according to degree airway blockage or location FB.An 11-month-old female infant visited a hospital sudden onset cough. She was relatively healthy without fever, rhinorrhea cyanosis, poor feeding. On physical examination, auscultation revealed inspiratory stridor wheezing crackles.Croup...
Background and Objectives Chronic rhinitis is divided into allergic (AR) nonallergic (NAR), both of which have similar symptoms but differ in treatment approaches. For the diagnosis AR, allergen-specific immunoglobulin E (IgE) tests along with characteristic are required. However, these costly not always practicable. The purpose this study was to investigate how respond differently different allergen sensitization or sensitized allergen. Subjects Method We retrospectively reviewed 1661...
The aim of the study is to assess effects continuous positive airway pressure (CPAP) on allergic rhinitis (AR) symptoms in patients with obstructive sleep apnea (OSA). Thirteen adult who had both OSA and AR were enrolled this study. All underwent treatment for 3months. Nasal assessed before initiation CPAP 3months after treatment. evaluated via Symptoms Allergic Rhinitis (SFAR) score, Obstruction & Septoplasty Effectiveness Scale (NOSE) questionnaire, Sino-Nasal Outcome Test (SNOT-25)...
Abstract The inherent mechanical properties of soft structures allow fragile objects to be safely manipulated without the need for precise force control. Soft and driving mechanisms are employed in applications ranging from gripping locomotion biomedical devices. Such can especially beneficial manipulating excessively relaxed live human tissue, relieve discomfort or medical conditions. An example is obstructive sleep apnea (OSA), where tissue narrows blocks upper airway while sleeping,...
