Outline of the department
Our department covers varieties of head and neck diseases and disorders. We diagnose and treat common diseases (such as otitis media, rhinosinusitis, pharyngolaryngitis, and tonsillitis), medical diseases (such as facial nerve paralysis, hearing loss and tinnitus) and surgical diseases (such as facial trauma and head and neck tumor). We also treat oral and maxillofacial diseases including a tongue cancer and a gingival cancer. To provide coordinated, comprehensive care, we work closely with local family doctors.
We provide many specialized out-patient clinics including hearing impairment, vertigo, tinnitus, and hearing aid clinic on Monday and Tuesday, allergic disease clinic on Tuesday, laryngeal disease, smell and taste disorder, and chronic otitis media clinic on Wednesday, thyroid and head and neck tumor clinic on Thursday, nasal diseases and facial trauma clinic on Friday.
We have more than 400 operations in a year including tympanoplasty, cochlear implantation, functional endoscopic sinus surgery, tonsillectomy, laryngeal surgety, resection of head and neck tumors and its reconstruction.
I. Basic research
[Regulation of airway inflammation]
1. Airway inflammation and defense system of upper airways
1) Mucus production and secretion in airway inflammation.
2) Regeneration and differentiation of epithelial cells in diseased airways.
3) Tissue remodeling of chronic airway inflammation.
4) Novel roles of coagulant and anticoagulant systems in airway inflammation.
5) Role of NO in nasal physiology.
6) Pathogenesis and treatment of smell disorders
7) Development of vaccine therapy for influenza virus infection.
8) Development of early diagnosis method for AlzheimerÃƒÂ¢Ã¢â€šÂ¬Ã¢â€žÂ¢s disease.
2. Novel roles of airway epithelial cells in the innate and adaptive immunity.
(Collaborated with Allergic Diseases Research Laboratory, Mayo clinic,
1) Roles of epithelial cell-derived cytokines (TSLP, IL-25, and IL-33) in airway
2) Functions of ST2 (a specific receptor for IL-33) in airway inflammation.
3. Pathogenesis of eosinophilic airway inflammation and its regulation.
1) Pathogenesis of eosinophilic mucus production.
2) Interaction of airway epithelial cells with eosinophils.
3) Novel functions of arachidonic acid metabolites in airway inflammation.
4) Development of the novel treatments for eosinophilic airway inflammation.
