Objectives Malignant external otitis (MEO) is a potentially fatal infection of the auditory canal, temporal bone, and skull base. Despite treatment with modern antibiotics, MEO can lead to base osteomyelitis. Until now, there have been few studies on prognostic factors MEO. Methods We performed retrospective study identify MEO, meta-analysis other articles investigating On basis disease progression 28 patients in our were divided into 'controlled' 'uncontrolled' groups, consisting 12 16...
Hearing loss is the most important modifiable risk factor for cognitive impairment; however, association of hearing with anatomical and functional connectivity not fully understood. This may be elucidated by evaluating findings newer imaging technologies.
Persistent postural-perceptual dizziness (PPPD) is a chronic functional vestibular disorder for which the Bárány Society has established diagnostic criteria. This nationwide multicenter study aims to investigate clinical features of individuals with definite PPPD and variant who do not fully meet criteria, particular focus on visual exaggeration.
Objectives The traditional canal wall down mastoidectomy (CWDM) procedure commonly has potential problems of altering the anatomy and physiology middle ear mastoid. This study evaluated outcomes in patients who underwent modified (mCWDM) mastoid obliteration using autologous materials. Methods Our included 76 with chronic otitis media, cholesteatoma, adhesive mCWDM materials between 2010 2015. Postoperative hearing airbone gap complications were evaluated. Results During average follow-up 64...
Inlay butterfly cartilage tympanoplasty makes the graft easy, and reduces operating time. The present study aimed to investigate outcomes of microscopic versus endoscopic inlay tympanoplasty.In this retrospective study, 63 patients who underwent with small medium chronic tympanic membrane perforation were evaluated. Twenty-four conventional 39 tympanoplasty. analyzed in terms hearing gain success rate.The surgical rate was 95.8% 92.3% those In both groups patients, postoperative air-bone gap...
A definitive study on the prevalence of adult unilateral hearing loss and aid rehabilitation is lacking in Korea. The purpose our was to investigate factors associated with use patients South We obtained data from 2009 2012 Korea National Health Nutrition Examination Surveys (KNHANES), a cross-sectional, nationwide population-based survey Republic analyzed adoption by univariable multivariable analysis. Unilateral defined as pure tone average ≥ 41 dB worse ear, < other ear assessed at 0.5,...
Deep learning (DL)-based artificial intelligence may have different diagnostic characteristics than human experts in medical diagnosis. As a data-driven knowledge system, heterogeneous population incidence the clinical world is considered to cause more bias DL clinicians. Conversely, by experiencing limited numbers of cases, exhibit large interindividual variability. Thus, understanding how 2 groups classify given data differently an essential step for cooperative usage application.This...
This article presents a comprehensive review of data on the impact facial palsy during coronavirus disease 2019 (COVID-19) pandemic. The possible causes and pathophysiological mechanisms changes in epidemiology COVID-19 pandemic are also discussed.
BACKGROUND:Isolated acute audiovestibular loss is characterized by the sudden onset of unilateral hearing and prolonged vertigo. OBJECTIVE:The purpose this study aimed to identify value magnetic resonance imaging (MRI) for evaluation isolated loss. MET HODS:We retrospectively enrolled 31 patients with from March 2007 December 2017. Specific medical records including initial final pure tone audiometry (PTA), canal paresis were reviewed. Abbreviated MRI was performed in all patients....
This study aimed to demonstrate the application of our automated facial recognition system measure nerve function and compare its effectiveness with other conventional systems provide a preliminary evaluation deep learning-facial grading systems.Retrospective, observational.Tertiary referral center, hospital.Facial photos taken from 128 patients paralysis two persons no history palsy were analyzed.Diagnostic.Correlation Sunnybrook (SB) House-Brackmann (HB) scales.Our results had good...
Inlay butterfly cartilage tympanoplasty (IBCT) is a simple grafting technique. Endoscopy facilitates visualization by eliminating blind spots. We analyzed the outcomes of IBCT using both endoscopic and microscopic approaches, assessed how trainees perceived educational opportunities afforded.Sixty patients who underwent were allocated to Group I (n = 30; IBCT) II dates their visits. Anatomical success was defined as an intact, repaired tympanic membrane; functional significant decrease in...
Objective: To describe a novel approach for intractable Ménière's disease exclusively through transcanal endoscopic ear surgery (TEES) approach. Patient: A 56-year-old male with despite conservative treatment and chemical labyrinthectomy. Interventions: Transcanal Main Outcome Measure: Subjective vertigo control, surgical morbidity. Results: The TEES provided wide exposure of the oval window. This facilitated removal stapes crura footplate. After widening window, perilymph was suctioned,...
Background Sudden sensorineural hearing loss (SSNHL) has several aetiologies and may be a presenting symptom of vestibular schwannoma (VS).Objectives The aim this study was to investigate the recovery rate after steroid treatment prognostic factors SSNHL with VS.Materials Methods This retrospective observational wherein 32 patients VS who presented were analysed at tertiary referral centre. Hearing gain main outcome measures for intervention.Results Among 1698 SSNHL, found in 43 (2.5%)...
Acute vestibular syndrome (AVS) is characterized by the rapid onset of vertigo, nausea, vomiting and gait unsteadiness, which lasts for days.We report cases as acute asymmetry disorder (AVAD), with presentations that mimic neuritis (VN) but without central lesions.We retrospectively reviewed records patients presenting spontaneous vertigo lasting more than 24 h from January 2011 to June 2016. Among 341 patients, five showed different findings did not indicate either VN or stroke. We analyzed...
Background and Objectives Pediatric obstructive sleep apnea (OSA) can have an effect on the quality of life (QOL) such as behavior, school performance, emotional distress daytime function. We aim to verify changes in disordered breathing based polysomnographic findings disease specific health related QOL before after adenotonsillectomy Korean children with OSA. Subjects Method A total 20 aged 3 through 13 years old (mean age=6.7 male/female=14/6) OSA were included. evaluated respiratory...
The association between programed cell death-ligand 1 (PD-L1) and tumor-infiltrating lymphocytes (TILs) in vestibular schwannoma (VS) has been investigated a few studies. These published studies report difference the PD-L1 positivity rate malignant peripheral nerve sheath tumors. We examined expression lymphocyte infiltration patients with VS who had undergone surgical resection clinicopathological features.The of PD-L1, CD8, Ki-67 40 tissue specimens was using immunohistochemistry, clinical...
Several studies have reported that the number of patients with Bell's palsy varied significantly by month and season. However, few monthly variation in based on whole population. We investigated Korea during a long-term period population data.
