Objectives To investigate the changes in incidence of otitis media and ventilation tube insertion (VTI) rates among South Koreans aged ≤18 years since COVID-19 pandemic analyze impact social distancing increased personal hygiene. Study Design A retrospective cohort study utilizing health insurance claim data. Setting Healthcare facilities across Korea. Patients Individuals diagnosed with acute suppurative (AOM), chronic serous (SOM), or mastoiditis (AM). Intervention Diagnostic therapeutic...
Many previous studies of high jugular bulb (HJB) have limitations, such as focusing simply on the incidence or having a relatively small number subjects. The objective this article was to investigate overall HJB and bony dehiscence in large scale using high-resolution temporal bone computed tomography. other purpose measure horizontal distance from tympanic annulus height above annulus. next step classify HJBs according relative levels compared with surrounding structures.Temporal...
Transcanal endoscopic ear surgery (TEES) provides minimally invasive transcanal access to the middle and improves visibility during cholesteatoma resection. However, literature on outcomes following TEES alone for removal of congenital (CC) is lacking limited small series.
<b><i>Objectives:</i></b> This study aimed to investigate the efficacy of simultaneous steroid and hyperbaric oxygen therapy (HBOT) in patients with severe profound idiopathic sudden sensorineural hearing loss (ISSNHL), which has a poor prognosis. <b><i>Methods:</i></b> Sixty diagnosed ISSNHL (≥70 dB HL) were randomly divided into two groups prospective controlled trial: an oral + intratympanic injection (ITSI) group (control group) ITSI HBOT...
Prevalence of tinnitus has been reported to vary according the target population and definition tinnitus. To improve understanding tinnitus, authors used nation-wide health claim data study in entire South Korea.Retrospective big review.Analysis from National Health Information Database.Patients diagnosed with International Classification Diseases code 10th edition (ICD-10) requested receive Insurance at least once January 2006 December 2015.None.Epidemiologic data, association otologic...
Objectives The operating microscope (OM) commonly used in ear surgeries has several disadvantages, including a low depth of field, narrow field view, and unfavorable ergonomic characteristics. exoscope (EX) was developed to overcome these disadvantages. Herein, we compared OM EX during mastoidectomy found out the feasibility EX. Study Design Prospective randomized comparative study. Setting Tertiary academic medical center. Patients who had for chronic otitis media with or without...
Objective: Our objective was to evaluate the surgical restrictions, audiologic benefits and satisfaction from using an active transcutaneous bone conduction device (BCD), Bonebridge® (BB) in patients with mixed/conductive hearing loss (MCHL) or single-sided deafness (SSD).Design: A retrospective review all who underwent BB surgery at Pusan National University Hospital 2015 2017 for SSD MCHL performed.Study sample: Twenty-two five had a implanted analysed.Results: Complete transmastoid...
Adipose-derived stromal cells (ADSCs) can repair auricular cartilage defects. Furthermore, stem cell secretome may also be a promising biological therapeutic option, which is equal to or even superior the cell. We explored efficacies of ADSCs and their in terms rabbit regeneration. were placed into surgically created After 4 8 weeks, resected auricles histopathologically immunohistochemically examined. used real-time PCR determine levels genes expressing collagen type II, transforming growth...
Idiopathic Sudden Sensorineural Hearing Loss (ISSHL) is an otologic emergency, and early prediction of prognosis may facilitate proper treatment. Therefore, we investigated the prognostic factors for predicting recovery in patients with ISSHL treated combined treatment method using machine learning models.We retrospectively reviewed medical records 298 at a tertiary institution between January 2015 September 2020. Fifty-two variables were analyzed to predict hearing recovery. Recovery was...
Objectives: To compare the outcomes of medial and lateral underlay endoscopic type I tympanoplasty for anterior tympanic membrane (TM) perforations. Study Design: Retrospective chart review. Setting: Tertiary care academic referral center. Patients: Patients who were diagnosed with either chronic otitis media dry stable TM perforations or traumatic underwent between 2017 2019. Interventions: Medial tympanoplasty. Main Outcome Measures: Patient demographics, size, location perforation, graft...
Objective: Hyperbaric oxygen therapy (HBOT) is an accepted treatment option for sudden sensorineural hearing loss (SSNHL), but it still recommended in combination with corticosteroids. We investigated the efficacy of salvage HBOT refractory SSNHL that does not respond to corticosteroid therapy. Methods: Eighty-four patients were included, who had unilateral improvement pure-tone average (PTA) less than 10 dB after using intratympanic plus systemic corticosteroids (combined therapy) as...
Tissue engineering cell-based therapy using induced pluripotent stem cells and adipose-derived (ASCs) may be promising tools for therapeutic applications in tissue because of their abundance, relatively easy harvesting, high proliferation potential. The purpose this study was to investigate whether ASCs can promote the auricular cartilage regeneration rabbit. In order assess differentiation ability, were injected into midportion a surgically created defect Control group with normal saline....
