We accept all patients with diseases covered by Otorhinolaryngology-Head and Neck Surgery (ear, nose/nasal sinuses, oral cavity, pharynx, larynx, neck and others). Specialist clinics in the following medical fields have been formed, striving to provide high-quality medical care services.

Tumor clinic: Mon., Tue., Wed., Thu., and Fri.
We treat about 200 patients with head and neck tumors annually. To treat patients with malignant tumors, all medical techniques, including surgical treatment, radiotherapy, and chemotherapy, are fully used to conserve the affected organ. Moreover, treatment policies are determined so that the patient's voice and swallowing may be kept as far as possible. We actively perform cranial base surgery.
Impaired hearing clinic: Mon., Tue., Wed., Thu., and Fri.
Surgical treatment is performed on more than 150 patients with chronic otitis media, chronic otitis media with cholesteatoma, and otosclerosis annually. Cochlear implantation is performed on patients with bilateral profound deafness. Drug medication and surgical treatment are performed on patients with sudden deafness and patients with facial palsy, respectively.
Dizziness clinic: Mon., Tue., Wed., Thu., and Fri.
This clinic diagnoses and treats patients with a wide range of conditions of dizziness including dizziness associated with inner ear function, e.g., Meniere's disease. Surgical treatment may be performed on patients with intractable Meniere's disease.
Nose/nasal sinus clinic: Mon., Wed., Thu., and Fri.
This clinic performs endoscopic surgery on more than 100 patients annually, mainly for nasal and nasal sinus diseases. A navigation system is used to safely treat high-risk anatomical sites. Endoscopy is also utilized in treating patients with maxillofacial fractures and lacrimal sac diseases. In addition to surgical therapy, we provide treatment with biological agents for refractory chronic rhinosinusitis. For allergic rhinitis, we offer not only drug therapy but also allergen immunotherapy and surgical treatment, either separately or in combination.
Vocal impairment/swallowing/respiratory tract clinic: Mon., Tue., Wed., and Fri.
We primarily focus on the general treatment of voice disorders, but we particularly specialize in surgical treatment for vocal cord paralysis, laryngeal papilloma, and glottic stenosis. We also offer vocal cord injection therapy and speech rehabilitation on an outpatient basis. Evaluation and surgical treatment for swallowing disorders are carried out in collaboration with our Swallowing Center.
Infantile deafness clinic: (only patients with appointment on Tue. afternoon)
Various kinds of test equipment are used to assess the hearing of infant patients to examine whether hearing aid attachment or cochlear implantation is appropriate for them. The clinic maintains close cooperation with otorhinolaryngologic clinics and special schools for the deaf in the community.


We provide high-quality medical care services to patients with all otorhinolaryngologic/head and neck diseases ranging from head and neck cancer to profound deafness and intractable dizziness. Moreover, we aim to establish close relationships with other hospitals and clinics, striving to provide medical care services that are optimal for patients.

Considerations in referring your patients to Otorhinolaryngology- Head and Neck Surgery

Please ask new patients you refer to us to bring a referral letter with them and submit it to the appropriate specialist clinic or attending doctor if possible. Otherwise, the patients must have consultation and be given examinations in the general clinic before they can make an appointment at the specialist clinic.
