[이데일리 이순용 기자] Professor Kim Min-beom and resident Hong Jun-pyo of the Department of Otolaryngology at Sungkyunkwan Kangbuk Samsung Hospital University School of Medicine (director Shin Hyeon-cheol) proposed a new treatment strategy through differences in damage patterns vestibular depending on the presence or absence of dizziness in case of sudden hearing loss.
In most cases, the cause of sudden hearing loss is difficult to determine, but the main pathogenic mechanisms are assumed to be viral infection and vascular disorders within the cochlea. To date, the standard treatment for sudden hearing loss is high-dose systemic steroid administration or intratympanic injection. If the cause is a viral infection, previous treatment may be effective, but if the cause is a vascular disorder, it is difficult to expect an effect of treatment, so treatment with hyperbaric oxygen or anticoagulant therapy is considered necessary. However, due to the complex structure of the cochlea, it is often difficult to accurately determine whether the cause of hearing loss is a viral infection or a vascular disorder, making it impossible to provide individualized treatment depending on the cause.
As a result, the research team of Professor Kim Min-beom from the Department of Otolaryngology of Kangbuk Samsung Hospital confirmed the presence of dizziness and vestibular damage patterns in 165 patients who visited our hospital with sudden hearing loss since 2017. to 2022 through a hierarchical clustering analysis method. In other words, patients with sudden hearing loss were divided into those with and without dizziness, and the results of hearing, dizziness and balance function tests were identified and analyzed for correlation.
Accordingly, in cases of sudden hearing loss accompanied by dizziness and impaired function of the posterior semicircular canal, the prognosis of existing steroid treatment was unfavorable. Therefore, sudden hearing loss accompanied by dizziness and decreased function of the posterior semicircular canal is highly likely to be caused by vascular disorders, so it is necessary to consider treatments that combine hyperbaric oxygen therapy or anticoagulant therapy from the outset rather than existing steroid treatments.
Professor Kim Min-beom from the Department of Otolaryngology at Kangbuk Samsung Hospital said: “Sudden hearing loss is a representative ENT emergency, with 40-50% of cases resulting in permanent hearing loss, although appropriate treatment is given in the early stages.” “It is above all important to quickly identify the cause and implement treatment,” he added. “It’s important and this study allows us to consider new treatments at an early stage,” he said, explaining the importance of the study.
This study was published in “Otolaryngology-Head and Neck Surgery”, a leading academic journal in the field of otolaryngology.
