研究室紹介
Professor Sung-won Chae's research lab focuses on the intersection of otolaryngology, aging, and systemic health, with key research directions including the impact of lifestyle factors—such as smoking—on hearing impairment, the role of systemic diseases (e.g., chronic myelogenous leukemia) in sudden sensorineural hearing loss, and the association between hearing loss and postural instability in older adults. The lab also investigates inflammatory pathways in otologic conditions, particularly the anti-inflammatory effects of compounds like CAPE on cytokine production, and conducts epidemiological studies on antibiotic-resistant pathogens in chronic ear infections. These multidisciplinary efforts aim to uncover biological mechanisms linking sensory function, systemic disease, and age-related physical decline.

15Current smoking was associated with hearing impairment in both speech-relevant frequency and high frequency across all ages. However, except in the ages of 40s, passive smoking was not related to hearing impairment in either speech-relevant or high frequencies.
Sudden sensorineural hearing loss that presents as the initial sign of haematological disease is very rare. Chronic myelogenous leukaemia has been implicated as a causative factor of sudden sensorineural hearing loss. A 49-year-old male presented with unilateral sudden sensorineural hearing loss. The patient was found to have chronic myelogenous leukaemia during a work-up for his hearing loss. We present a case of a chronic myelogenous leukaemia patient whose first manifestation was sudden senso
Aging, female sex, and having hearing loss were associated with postural instability in this analysis. Moderate or worse hearing loss present on at least 1 side was associated with increased odds of postural instability. Future research in this area is warranted to identify more precise interrelationships and preventive measures.
Postural dysfunction is one of the most common community health symptoms and frequent chief complaints in hospitals. Sarcopenia is a syndrome characterized by degenerative loss of skeletal muscle mass, muscle quality, and muscle strength, and is the main contributor to musculoskeletal impairment in the elderly. Previous studies reported that loss of muscle mass is associated with a loss of diverse functional abilities. Meanwhile, there have been limited studies concerning postural dysfunction am
CAPE significantly inhibited LPS-induced up-regulation of TNF-alpha in a dose-dependent manner. IL-8 production by LPS was significantly suppressed by the CAPE pretreatment. Furthermore, LPS-induced IkappaB-alpha degradation was suppressed by the CAPE pretreatment.
OBJECTIVES: To investigate the epidemiologic and microbiological characteristics of community-acquired methicillin-resistant Staphylococcus aureus (CA-MRSA) and hospital-acquired methicillin-resistant Staphylococcus aureus (HA-MRSA) infections in the otorrhea of chronic suppurative otitis media (COM) patients. DESIGN: Retrospective study of patients with newly identified MRSA infections from January 1998 through December 2006. A total of 2773 patients with a diagnosis of COM were included in thi
Age-related hearing impairment (ARHI) is becoming a more significant issue as geriatric population increases. Sarcopenia in older people is known to have a diverse health problem in various circumstances in recent studies. We assessed whether the decrease in muscle mass is related to ARHI. We used the 2010 data of the Korea National Health and Nutrition Examination Survey (KNHANES) to examine the associations between sarcopenia and ARHI. A total number of participants was 1,622 including 746 mal
