I have investigated the pathogenesis and development of novel diagnosis and treatment in intractable chronic upper airway diseases including allergic rhinitis and eosinophilic chronic rhinosinusitis. My recent scientific interests have focused on the prediction of efficacy of sublingual immunotherapy, the curative treatment for allergic rhinitis, using saliva, and role of IgG4 in the pathogenesis of eosinophilic chronic rhinosinusitis. If you are interested in these topics, please join to us. Of course, researches other than these topics including otology such as hearing, pharyngo-laryngology such as voice, and head and neck surgery and medicine such as cancer, are welcome.
