Characteristics of dental care

1. Sudden hearing loss

Early diagnosis and treatment are essential. Treatment with steroid and drip infusion of thrombolytic agent for 6 consecutive days

3. Dizziness

Testing for the cause of dizziness and treatment

Examination by palpation, visual inspection with a fiberscope, and detailed examination with echography, CT, or MRI. Cytology/histology.

Efforts for state-of-the-art dental care

We will conduct minimally invasive examinations and endoscopic procedures.
In the case of malignant tumor of the head and neck area, we will refer to a medical institution where intensity modulated radiation therapy (IMRT) or heavy ion radiotherapy is performed considering functions and esthetics.
