Dr. Hiro Nakatomi

Greetings and welcome to the website of the acoustic neuroma and skull base meningioma surgery practice of Dr. Hiro Nakatomi in Tokyo (Toranomon), Japan. It is my pleasure and privilege to invite you to choose the Acoustic Neuroma Cure Center (ANCC) as your new medical home.

Over the past 17 years, we have treated more than 200 acoustic neuromas and more than 90 skull base meningiomas both in Japan and in the United States. The total number of cranial and spinal surgeries performed has been more than 1,400. Indeed, we have been pioneers of monitoring-based minimally invasive (MBMI) neurovascular surgery for more than 3.5 years. We utilized MBMI techniques for more than 150 cases.

My team and I are delighted to be able to provide exceptional neurosurgical care in an open, transparent, and patient-centered environment. We build strong relationships with our patients, and strive to create pleasant medical-care experiences.

We produce excellent and long-lasting results in terms of hearing and facial function, and provide a long-term cure for acoustic neuroma. We are proud of the longevity and reputation of our team. Our team and I have collectively more than 34 years of experience.

Dr. Nakatomi, is the only surgeon today to have done a lengthier and more specialized training to include skull base, neurovascular and neuro-otological fellowships at both Mayo clinic, Rochester and University of Cincinnati/ Mayfield clinic in addition to Tokyo University Neurosurgery residency .

The cornerstones of our practice are internationally patented techniques for MBMI-acoustic neuroma surgery (ANS), holistic patient care, extensive neurosurgical knowledge, and many years of experience.

Our practice and procedures

MBMI-ANS

The ANCC is a designated Center of Excellence, and is the first and only center to be devoted exclusively to the arts of both ANS and hearing regeneration.

It is the world leader in performing procedures using MBMI neurosurgical techniques.

Moreover, it is the only center at which exclusively monitoring-based surgery is used to treat primarily acoustic neuromas.

Dr. Nakatomi has treated over 1,400 patients. His MBMI-acoustic neuroma surgery has over 98% effective rate.

We also treat other meningiomas, giant aneurysms, and brain arteriovenous malformations by the same technique.

These techniques achieve near complete preservation of the nerves and brain functions of patients, and lead to faster recovery than traditional craniotomies.

Most trained neurosurgeons have had little, if any, experience of working with the skull base region. By contrast, the ANCC’s Director, Dr. Nakatomi, has undergone lengthy and specialized surgical training including skull base, neurovascular and neuro-otological fellowships at both the Mayo Clinic, Rochester, and the University of Cincinnati/Mayfield Clinic in the United States in addition to Tokyo University Neurosurgery residency.

These skills make the ANCC team uniquely qualified to operate on the most complex area of the human body, and have contributed to our success in treating over 1,400 patients with neurological disease.

How do you know if this procedure is right for you?

  1. You’ve tried other procedures and they didn’t work.

  2. You want to use a procedure that is 98% effective compared to traditional operations instead of that has been proven to be less effective for your face and hearing.

  3. You’re busy and don’t want to spend more than 2 weeks in recovery.

We have achieved the best results to date for acoustic neuroma, of more than 10,000 practicing neurosurgeon in the world.

We have preserved excellent facial nerve function in more than 94% of our cases even during the immediate postoperative period, and this figure has improved to 98% after 6 months.

Furthermore, overall hearing has been preserved in more than 90% of our cases. Effective hearing has been maintained in more than 80% of cases.

In every case, regardless of the tumor size, we have achieved greater than 95% tumor removal.

There’s more to the treatment of acoustic neuroma than you might realize, particularly if any of the following apply to you:

  1. You have questions about hearing impairment owing to a tumor of the auditory nerve, or questions about the treatment of problems with gamma-knife surgery.

  2. You need further surgery for a recurrent tumor or are worried about a residual tumor.

  3. You want a second opinion from an experienced surgeon.

  4. You have long-term experience of the disease, and are interested in a consultation and treatment focused on maintaining your quality of life.

  5. You want to consult a doctor with vast surgical experience and are looking for a safe surgical procedure without sequelae.

  6. You want to undergo state-of-the-art minimally invasive surgery using continuous intraoperative nerve monitoring for your acoustic neuroma.

Mrs. H.H. Testimonial

I saw an ear, nose, and throat doctor, and underwent magnetic-resonance imaging that showed a "brain tumor behind the ear” on my right side.

I was really glad that the operation was carried out with no complications, and I have the utmost gratitude.

After 1 year, I no longer misheard some sentences, and could participate fully in conversations and debates.

During the physical examination, despite the serious content, my doctor and I were still able to laugh, and I gained a great sense of satisfaction, comfort, and hope.

I was able to go home with these fantastic feelings.

With much gratitude and thanks,

Mrs. I.T. Testimonial

This patient had a medium-sized tumor (10–15 mm). The pure tone average (PTA) hearing level was 32 dB, and the speech discrimination score (SDS) was 90%. He underwent complete resection of the tumor. He had no facial paralysis even immediately after the operation. His hearing was maintained at a PTA of 37.5 dB and an SDS of 85% postoperatively. He has been in good health without recurrence for the past 3 years.

I am now working as a service representative, just as I did preoperatively, after spending only 1 month in the hospital undergoing the surgery and another month at home recuperating”.

I took the right course of action to cure my acoustic neuroma. I am very grateful to my surgeon, Dr. Nakatomi. I am writing this testimonial to let others know my feelings and thoughts, in order to help them to make a choice, because my acoustic neuroma was cured by Dr. Nakatomi.

My hearing on the right side is becoming very stable. I certainly can hear and understand what is said when in company.

Dr. Nakatomi treated me with sincerity, generosity, and kindness at all times, even after the operation was over.

Ms. N.S. Testimonial

This patient was a 20-year-old female who had bilateral acoustic neuromas.

She had the tumor on the left side removed 2 years ago and eventually became deaf in that ear. Subsequently, the tumor on the right side grew to 20 mm in size, and she suffered sudden hearing difficulties in the same ear twice more during the past 6 months. This episode prompted her to visit our hospital.

I really thank you for removing 95–97% of my tumor. I will now have my hearing for another 5 years or more. Fantastic! I was really glad to hear from Dr. Nakatomi that I should be able to take a permanent job in whatever I am interested in.

There is no other doctor for treating this disease. I have full trust and confidence in all of the treatments that he gave me.
