Department of Otorhinolaryngology

Main medical services

We provide treatment for patients with general diseases of ears, nose and throat, as well as advanced therapy for patients especially with hereditary hearing loss and obstructive problems in the upper respiratory airway.


Congenital hearing loss

We examine the patients suspected hearing loss by means of newborn hearing screening if having hearing loss through an auditory brainstem response (ABR) or other detailed examination. If we diagnosed them as hard of hearing, investigate the cause of the hearing loss, including genetic examination and molecular diagnosis for congenital cytomegalovirus infection. 

The hearing tests we perform are: Behavioral Auditory Response Audiometry (BOA), Conditional Onset Response Audiometry (COR), Infant Play Audiometry, Standard Pure Tone Audiometry, Speech Audiometry, ABR, and ASSR (air and bone conduction).

Please note: ABR and ASSR tests are by appointment only and cannot be done on the day of the first visit, since ABR and ASSR in children require sedation and careful handling.

Cochlear implant surgery for bilateral severe sensorineural hearing loss

We perform cochlear implantation for the patients with bilateral severe sensorineural hearing loss according to the criteria for cochlear implantation set by the Japanese Society of Otolaryngology and the cooperation with the family and the child's educational institution. Our center started cochlear implantation in 2011, and simultaneous bilateral surgeries are also available. 

Chronic perforated otitis media, cholesteatoma, and congenital malformation of the ossicles (conductive hearing loss)

Depending on the size of the ear canal and the condition of the lesion, we perform microscopic and/or transcanal endoscopic ear surgery (TEES). 


We have extensive experience with airway surgery such as tracheostomy, laryngotracheal separation, or supraglottoplasty etc.
In order to make an accurate diagnosis, it is often necessary to perform not only outpatient fiberscopic examination but also fiberscopic examination and direct laryngoscopy under general anesthesia. If conditions permit, we perform examination and surgery under natural respiration without intubation tube into the trachea, which is a major feature of our department.
Target disease:
laryngomalacia, subglottic stenosis (congenital or acquired due to intubation), subglottic hemangioma, laryngeal cyst, laryngeal papilloma, vocal cord paralysis (recurrent nerve palsy), posterior glottic adhesion, and laryngeal diaphragm

Treatment of congenital cervical cystic disease


congenital ear fistula, shortened lingual strip, chronic sinusitis, sleep apnea syndrome, congenital cervical cystic disease, etc.
