Dr. Rhoton made a significant contribution to the development of neurosurgery in Japan. He was invited to many Japanese meetings

RI PT

including the annual meetings of the Japan Neurosurgical Society and the Japanese Congress of Neurological Surgeons. He was instrumental in first introducing the concept of, and then disseminating the new knowledge

SC

gained from, the study of microsurgical anatomy as a means to improve the techniques and outcomes of microsurgery. Forty-one Japanese fellows from

M AN U

Japan studied in Dr. Rhoton’s laboratory and helped, on their return, to promote the usefulness of the laboratory’s work for clinicians. In this honorary article, I would like to focus on how the knowledge and techniques that Dr. Rhoton passed on to his fellows spread and flourished in Japan through his fellows’ activities.

TE D

Most Japanese fellows were not good at communicating in English. Dr. Rhoton, however, was very kind and patient in listening to the poor English spoken by his

EP

Japanese fellows. Dr. Rhoton’s own speech, slow and soft, was easily understood by the Japanese fellows, and this was greatly appreciated. Because of his contribution to

AC C

medicine and his compassionate personality, Dr. Rhoton was widely respected by Japanese neurosurgeons, regardless of whether or not they had trained with him. The first Japanese fellow was Dr. Shigeaki Kobayashi of Shinshu University, who

trained with Dr. Rhoton at the Mayo Clinic from the late 1960s to the early 1970s, before Dr. Rhoton moved to the University of Florida. They realized the necessity of the precise study of anatomy through the operating microscope in order to preserve the facial nerve during the removal of an acoustic neurinoma, and published a paper titled

“Nervus intermedius” in the Journal of Neurosurgery in 1968 (1). To the best of my knowledge, this was one of the first articles on microsurgical anatomy, and Dr. Rhoton

RI PT

established this field as a new research area in neurosurgery directly related to surgical procedures.

In 1972, Dr. Rhoton assumed the position of Director of the Division of

SC

Neurosurgery in the Department of Surgery at the University of Florida, established a research laboratory (Rhoton Lab) for microsurgical anatomy and began his untiring

M AN U

work. Subsequently, a total of 41 young Japanese doctors (all neurosurgeons except for 1 plastic surgeon and 1 otolaryngologist) studied under him as research fellows. After returning to Japan, these young doctors not only propagated the knowledge and techniques they had learned at the Rhoton Lab throughout Japan but also actively

worked as clinicians utilizing their expertise. Eight of them became chairmen at their

EP

The most significant contribution to Japanese neurosurgery by these fellows was the establishment of the annual meeting of the Japanese Society for Microsurgical

AC C

Anatomy (2). The first meeting of the Society was organized at Kyushu University in Fukuoka in 1986, when Dr. Rhoton was invited to attend the retirement ceremony of Prof. K. Kitamura from the Department of Neurosurgery at Kyushu University. (Fig.1) Dr. Evandro de Oliveira, from Sao Paulo, Brazil also participated in the meeting. Since then, this meeting has been held yearly, and this year the Society will celebrate its 30th anniversary. The meetings have been successful, often attracting over 800 participants at one

time, even during the early years when neurosurgeons in Japan numbered no more than 4000, less than half the current number. The proceedings of the meeting, published in

RI PT

Japanese annually and called “Surgical Anatomy for Microneurosurgery,” often sold more than 3000 copies. (Fig.2) They are very popular among Japanese neurosurgeons as practical anatomy textbooks written in Japanese and have played an important role in

SC

neurosurgical education and development.

For the purposes of facilitating the education of young neurosurgeons, the Japan

M AN U

Neurosurgical Society asked Dr. Rhoton to lend his support in the making of a video series on microsurgical anatomy. He kindly accepted the request and the series was produced as a collaborative project by the Japan Neurosurgical Society and the University of Florida between 1992 and 1993. For this project, 9 former Rhoton fellows

TE D

visited the University of Florida to produce educational video tapes on 10 topics. (Fig.3) In accordance with the increased demand for international seminars on

EP

microsurgical anatomy, the first International Symposium on the Microsurgical Anatomy was held in October, 2002 in Matsumoto, Japan (President: T. Matsushima),

AC C

as one of the satellite symposia of the 61st annual meeting of the Japan Neurosurgical Society. (Fig. 4) Dr. Erdener Timurkaynak from Ankara, Turkey and Dr. Evandro de Oliveira from Sao Paulo, Brazil, both former research fellows at the Rhoton Lab, have organized subsequent international meetings, three times in Turkey and once in Brazil, inviting Dr. Rhoton as their co-President and several other experts from around the world as speakers. These international seminars have contributed to the professional development of many neurosurgeons not only in their host countries but also in

neighboring regions. Dr. Rhoton, then, not only originated the concept of microsurgical anatomy but

RI PT

also promoted the use of anatomy-based surgical techniques throughout the world. I would also like, however, to write about what I knew of his personality.

When he traveled, he always carried a heavy suitcase full of the slides and papers

SC

he was working on at the time. His habit of working continuously resulted in more than 500 scientific papers and chapters. He compiled his life’s work into a single textbook

M AN U

entitled “Rhoton: Cranial approaches and surgical anatomy”. (3)

He did not drink. He not only spent his evenings but also most of his weekends working. He appeared to enjoy his research as if it were his hobby. In fact, he said to me when I was a fellow, “Study hard and it will become your hobby”. I then thought it was

TE D

only a joke, but now, as I have become older, I understand what he really meant. He visited Japan quite a few times, and at parties he often urged a few young

EP

fellows to do push-ups with him. (Fig. 5) As far as I know, no one was ever able to do more push-ups than Dr. Rhoton. He never skipped his daily jogging or iron array

AC C

training, even while traveling. It was his continuous self-training that fuelled the enormous energy and passion he brought to his work. As Dr. Rhoton became older, he used the words “competence” and “compassion”

many times in his speeches. He said that it was a great challenge for a neurosurgeon to care for his/her patients with competence and compassion. In fact, he spent considerable time with his patients both before and after surgery, helping them understand the nature of their illness and the surgery they underwent.

During his early career, he realized the great potential for developing our knowledge of microsurgical anatomy to refine the techniques of microneurosurgery and

RI PT

thereby improve the standards of care given to patients, and so he began the relentless research which was to last for more than 40 years until his recent death. In conclusion, let me quote a phrase from his book:

SC

“Our work is not complete in any area…There is no ‘finish line’… Future anatomical study will continue to yield new insights throughout the future of our specialty.

M AN U

Insights gained from the other medical sciences and new technologies, when combined with our increasing knowledge of microsurgical anatomy, will create new surgical

possibilities, therapies, and cures”. (3, p. vi)
