Objectives/Hypothesis There may be an interobserver variation in the diagnosis of laryngeal disease based on laryngoscopic images according to clinical experience. Therefore, this study is aimed perform computer‐assisted for common diseases using deep learning‐based classification models. Study Design Experimental with retrospective data Methods A total 4106 (cysts, nodules, polyps, leukoplakia, papillomas, Reinke's edema, granulomas, palsies, and normal cases) were analyzed. After equal...
Coronavirus disease 2019 (COVID-19) changed the practice of medicine, and various anti-contagion restrictions were implemented worldwide. This study aimed to evaluate annual trend in incidence otologic diseases during COVID-19 pandemic determine influence social on these diseases. We retrospectively reviewed number patients treated for diseases, particularly those associated with infectious pathophysiology, total otolaryngology departments at three tertiary referral centers South Korea. The...
Balloon eustachian tuboplasty (BET) is an emerging treatment for dilatory tube (ET) dysfunction. However, its efficacy in patients with both chronic suppurative otitis media (COM) and ET dysfunction remains unclear. The objective of the trial was to assess safety BET versus medical management (MM) alone adult COM dysfunction, which defined by a failed Valsalva maneuver. In this prospective, multicenter, randomized controlled trial, total 116 participants (121 ears) treated between January...
Objective To review a 3-year case series of endoscopic butterfly inlay cartilage myringoplasty performed by single surgeon (W.S.K.) and analyze the clinical surgical outcomes. Study Design Retrospective study. Setting Tertiary care academic center. Patients We enrolled 60 ears with tympanic membrane (TM) perforation, receiving between 2019 2022. Main outcomes Measures reviewed patients' demographics, size location TM operation time, complications, postoperative pain evaluated numerical...

Group 2 innate lymphoid cells (ILC2s) contribute to the pathogenesis of eosinophilic chronic rhinosinusitis with nasal polyps (CRSwNPs). However, role other subsets ILCs and differentiation in CRSwNPs is not well understood. This study aimed characterize ILC evaluate from precursors (ILCPs) NP tissue.ILC ILCPs were evaluated by flow cytometry fresh sinonasal mucosa patients control subjects. Subsets compared based on clinical variables immunological features patients. Sorted...
Objective: Nasal septal perforation (NSP) repair is challenging surgery considered in patients with symptomatic NSP intractable to conservative treatments. This study aimed assess the success rate and identify factors affecting surgical outcome of by analyzing consecutive series repairs a single surgeon. Methods: We enrolled 84 diagnosed who underwent surgeon (Y.J.J.) between November 2007 July 2022. Medical records were retrospectively reviewed regarding variables involving preoperative...
To analyze the long-term auditory performance after cochlear implantation (CI) and identify anatomical features of Mondini dysplasia associated with post-CI outcomes.Retrospective study.Tertiary care academic center.We enrolled 49 ears who underwent CI more than 7 years follow-up age at CI- sex-matched control group radiologically normal inner ears.The development skills was evaluated using word recognition scores (WRSs). The were measured based on temporal bone computed tomography magnetic...
This study aims to analyse the volumetric changes in brain MRI after cochlear implantation (CI), focusing on speech perception postlingually deaf adults. We conducted a prospective cohort with 16 patients who had bilateral hearing loss and received unilateral CI. Based surgical side, were categorized into left right CI groups. Volumetric T1-weighted obtained before one year surgery. To overcome artifact caused by internal device post-CI scan, image reconstruction method was newly devised...
Cochlear implant (CI) users face the decision of whether to upgrade a new sound processor (SP) with technological advances. We wanted assess changes speech perception ability and aided hearing thresholds as well subjective satisfaction after SP.
Objective To evaluate the audiologic outcomes after cochlear implantation (CI) in prelingually deaf children with comorbid disorders. Study Design Retrospective study. Setting Tertiary care academic center. Patients We enrolled 85 (111 ears) disorders who underwent CI surgery. Main Outcomes and Measures selected most common disorder compared categories of auditory performance (CAP) scores each comorbidity group those control group. Combined anomalies were also evaluated using temporal bone...
Background Optimizing the educational experience of trainees in operating room is important; however, ear anatomy and otologic surgery are challenging for to grasp. Viewing surgeries often involves limitations related video quality, such as visual disturbances instability.
Intralabyrinthine schwannomas are rare benign tumors, which arise from neural portions within the labyrinth. These subclassified into seven groups according to affected inner ear structures. Intracochlear (ICS) tumors confined cochlea, and these can cause progressive unilateral sensorineural hearing loss, tinnitus, vertigo aural fullness. Here, we report a 49-year-old female patient with left sudden loss. There was no improvement of despite steroid hyperbaric oxygen therapy. Space occupying...
Hypopharyngeal cancer is managed by either surgical resection or radiation therapy-based treatment. In choosing the treatment modality, patient's swallowing function should be considered to achieve optimal outcomes. This study aimed stratify risk factors predictive of postoperative dysphagia in hypopharyngeal cancer. Retrospective study. Tertiary referral center. We enrolled 100 patients who were diagnosed with and underwent curative surgery between January 2010 December 2019,...
Autoimmune disease-associated laryngotracheal stenosis (AD-LTS) is very rare but can pose a life-threatening risk. Pathogenesis of AD-LTS still uncertain and standard treatment protocol has not been proposed. In this study, we reported two cases in patients with relapsing polychondritis rheumatoid arthritis, respectively. Two middle-aged female visited our clinic due to progressive dyspnea, subglottis upper trachea was identified. Under general anesthesia, stenotic area dilated balloon...
Background and Objectives Meniere’s disease (MD) is primarily managed by lifestyle dietary changes. There are several non-medical treatment options for medically intractable MD; however, results still remain controversial. This study aims to review the outcome of endolymphatic sac decompression (ESD) intratympanic gentamicin (ITG) MD refractory medical management.Subjects Method The records 50 patients, diagnosed with definite management, who underwent ESD or ITG from 2010 2020 at a tertiary...
