Check out our Tentative Program for the 4th World Congress

Time is flying by, and we are approaching the two-month countdown to the opening of the 4th World Congress on Endoscopic Ear Surgery in Kyoto. Those of us on the different organizing committees have been busy putting together the Program. While it is subject to change, we wanted to release a Tentative Program so that you can get an idea of how the schedule is shaping up. I think that once you take a look at it, you will agree that it is jam-packed with a lineup of impressive Keynote Lectures, Round Tables, Panel Discussions and Instructional Courses given by experts in the field of endoscopic ear surgery.

If anyone is still undecided about attending, I hope that our Tentative Program will help you to realize that there is no better place to be in early December than Kyoto. Click here to take a look!

A Glimpse into the Sublime World of Ikebana

We are delighted to welcome Ryuho Sasaoka to the 4th World Congress on Endoscopic Ear Surgery in Kyoto. He will be a featured performer during the Opening Ceremony of the Congress which will be held on December 5th in the ROHM Theater Kyoto. Mr. Sasaoka will be demonstrating a side of Japan that some of you may be familiar with, specifically Ikebana, or literally “living flowers.” Ikebana is often called “Japanese flower arranging” which conjures up images of static arrangements of flowers in full bloom.

However, ikebana is so much more than that. Ikebana is an art form and philosophy which is based on the entire life cycle of flowers and what that life cycle can teach us.

Mr. Sasaoka is the head of the Mishoryu-Sasaoka Ikebana School which was founded by his grandfather in 1911. While he has worked to preserve and carry on the traditions of the school, he has also sought to expand the scope of ikebana through dynamic live performances of flower arrangement. He has performed for both Japanese and international audiences and we are grateful that he accepted our invitation to perform for us.

Reopening the Call for Abstracts

Lateral skull base (LSB) pathology represents a challenge for the surgeon. Thanks to the improvements in surgical instrumentation and a growing body of surgical experience performing LSB procedures, the endoscope has gone,

We have had several inquiries about whether it is too late to submit an Abstract for the EES2022 World Congress. While we ourselves have never ever missed a deadline (???), we decided in the spirit of openness and the recognition that getting things done and planning ahead have been really, really hard in the past couple of years, to reopen submissions for Abstracts.

You can submit your Abstract via the Call for Abstracts page on our website. I strongly encourage anyone who was on the fence about presenting in Kyoto to submit the fruits of your research.

Please note that the reopening of the Call for Abstracts is only for new submissions. Revisions to previously submitted Abstracts will not be accepted.

The deadline for submission of new Abstracts is Wednesday, September 21st, 2022, 12:00 noon (Japan Standard Time, UTC+9).

We look forward to seeing you in Kyoto in December.

Livio Presutti, MD
Chair of the 2nd WCEES in Bologna

Lateral skull base (LSB) pathology represents a challenge for the surgeon. Thanks to the improvements in surgical instrumentation and a growing body of surgical experience performing LSB procedures, the endoscope has gone, in the last fifteen years, from being an adjunct instrument to improve visualization, to a technical tool that allows surgical maneuvers in hidden or complex areas of the surgical field.

Endoscopic approaches have been developed through the natural orifice of the external auditory canal, such as the transpromontorial, the infracochlear and the suprageniculate approach. At the same time, considerable experience has accumulated on the use of the endoscope during specific phases of traditional approaches to the LSB, particularly the retrosigmoid and the translabyrinthine approaches.

This Keynote Lecture will encompass both exclusive endoscopic and endoscopic-assisted approaches to the LSB. Special emphasis will be on the technical refinements and possible pitfalls based on the extensive personal experience of the lecturer.


Message from a Guest of Honor
Dr. Muaaz Tarabichi MD
Chair of the 1st WCEES in Dubai

Nasal endoscopic access to the Eustachian tube has excited a new interest in the Eustachian tube and its dysfunction with attempts at better understanding of obstructive pathologies and new interventions. Wide adaptation of endoscopic ear surgery and its superior access to the protympanum promises to provide a similar catalyst for better understanding of the ear side of the Eustachian tube and provide a new understanding of the anatomy, importance, function and dysfunction of that segment of the Eustachian tube. Many new diagnostic methods are also well within the reach of our hands that should allow us to better understand the role of the proximal Eustachian tube in chronic otitis media.


One Door Closes but Another Has Opened

The deadline has passed for Abstract submissions, and I am happy to announce that we received around 300 Abstracts from individuals all around the world! This number is even more impressive in light of the political, economic and medical challenges facing all of us today. It is a testament to the growth and strength of our community and the spread of endoscopic ear surgery.

I am also pleased to announce that Registration is finally open for the EES2022 Congress in Kyoto. Early Bird registration will run until October 31st (Mon) 2022 with Regular registration running until November 18th (Fri) 2022. You can access the Registration Page at

For any of you still weighing the pros and cons of attending the Congress, let me tell you that visiting Japan has not only never been cheaper, but you will also get a rare opportunity to enjoy your stay in Kyoto without battling hordes of tourists.

I thus encourage everyone to register early to take advantage of both the Early Bird rate and the weak yen which is currently hovering around 133 yen to the dollar (compared to around 110 yen to the dollar of the last couple of years). You are getting a close to 20% discount from last year just on the exchange rate!

If you run into any problems with your registration, please contact the EES2022 Registration Desk at

We will also be sending out information on visas in the upcoming days. Since visas require entry within a three-month period, we will be starting processing on our side from the beginning of September.

Looking forward to seeing you all in Kyoto!

Meet the man who started it all

Our Guests of Honor list is already an embarrassment of riches with our lineup made up of Dr. Yasuya Nomura, Dr. Livio Presutti, Dr. Muaaz Tarabichi and Dr. Jacques Magnan as well as the late Dr. Naoki Yanagihara. However, today I would like to take this opportunity to announce the addition of another very special Guests of Honor, Dr. Jean-Marc Thomassin. Dr. Thomassin is truly a pioneer of endoscopic ear surgery who took the lead in developing and refining endoscopic ear surgery procedures. Moreover everyone of us has taken in hand his namesake surgical tool, the Thomassin dissector, which greatly facilitated the successful performance of endoscopic ear surgery.

I am so pleased that Dr. Thomassin has accepted our invitation to attend the EES2022 Congress as our honored guest. I look forward to welcoming to Kyoto one of the true fathers of endoscopic ear surgery.

Abstract submission extended!
Good News for the Undecided and Procrastinators Among Us!!

I wanted to let everyone know that we have extended the deadline for submission of Abstracts from July 1st to July 14th (Thursday) 12:00 noon Japan time.

If you were sitting on the fence about submitting an Abstract and let the deadline pass, we are offering you a second chance to let the international EES community know what you have been working on. EES is one of the most exciting areas of otology and we need to show the world what can be achieved through EES.

In addition, we are in the process of planning Panel Discussions, Round Table Discussions and Instructional Courses. We will also be reviewing the submitted Abstracts to see if the authors would be good candidates for participation in any of the aforementioned events.

So don’t miss this opportunity and I look forward to seeing the submission of additional Abstracts.

To the EES Worldwide Community,

I hope that you are all doing well. I would like to take this opportunity to update everyone on the status of the EES2022 in Kyoto.

The 4th World Congress on Endoscopic Ear Surgery will be held, as scheduled, from December 5th to the 8th, 2022 in Kyoto Japan with the Satellite Symposium held from December 12th to the 13th in Yamagata Japan. Both events will be held live face-to-face with no live streaming.

Thus, it is now time to start making your plans to attend!

The Japanese government has begun to lift restrictions on business visitors from overseas and there is talk of allowing tourists to enter in the near future. We will provide further information at a later date on the visa situation, but also please check with the local Japanese embassy in your country for further information and updates as the Congress date approaches.

The Call for Abstracts will be opened from May 12th, and I am looking forward to seeing what everyone has been working on in the years since our previous World Congress in Boston.

We will also be announcing the opening of registration for the 4th World Congress on Endoscopic Ear Surgery in the near future. Please stay tuned for further information in this regard!

It is an understatement to say that it has been a longer than usual journey to the 4th World Congress with many unforeseen challenges and bumps in the road. I am truly grateful for everyone’s understanding as we have navigated those challenges.

I am optimistic that we will be able to raise a glass of sake (or your beverage of choice) in December to toast the success of the 4th World Congress on Endoscopic Ear Surgery in Kyoto.

4th World Congress on EES in Kyoto to Move to December 2022
I think that the past year-and-a-half has taught all of us around the world that nothing scheduled is set in stone! When I moved the 4th World Congress on EES in Kyoto to April 2022, I was confident that the challenge of COVID 19 would be overcome by then, and that international travel restrictions would be lifted. However, the last couple of months have made me realize that that timeline was too optimistic. In light of the spread of the delta variant and increasing case numbers around the world, I have made the decision to once again move the date of the 4th World Congress on EES in Kyoto.

Our new date is now December 5th to the 8th of 2022. While I realize that this date is close to the end-of-the-year holiday season, it was the best choice out of the available dates for our venue. The weather in Kyoto in early December is mild and while we will miss the Kyoto cherry blossoms, the city should still be beautifully bathed in the fall foliage including its stunning maple trees.

I thus ask everyone to pencil this new date and cross your fingers that we will have COVID 19 under control by then. While our conference is important to those of us in the field of endoscopic ear surgery, it pales in importance to the good health and well-being of the world community at large. Let us all continue to work together to defeat COVID!
I hope to see you in Kyoto in December 2022!

The Chair of the 4th World Congress on Endoscopic Ear Surgery, Dr. Seiji Kakehata, sat down for an interview with Dr. Tatsuya Yamasoba of the University of Tokyo for ENT & Audiology News. They discussed a number of topics including endoscopic ear surgery and preparations for the 4th World Congress. You can read the interview at ( ) or download the PDF here.
April. 30, 2021
Dr. Naoaki Yanagihara, a leader in otology in Japan and the developer of the Yanagihara Scale for evaluating facial nerve palsy, was scheduled to be honored as a pioneer of endoscopic ear surgery during the 4th World Congress. However, we were greatly saddened to be informed that Dr. Yanagihara passed away at the end of 2020. We shall thus be presenting a special memorial tribute in honor of his life and achievements.

・Notes from our chair
Greetings to everyone!

We are starting to gear up for the World Congress on Endoscopic Ear Surgery in Kyoto which will be held in less than a year-and-a-half! It was my pleasure to recently welcome Dr. Aaron Remenschneider from Harvard and his lovely wife Emily to Kyoto where he gave a presentation at the 2019 Japan Audiological Society.

We were able to show them around Kyoto and they were kind enough to describe their impressions of the city in a blog posting. For those of you who are thinking about attending the World Congress, I think that their perspective should give you a good idea of what you could expect on a trip to Kyoto.

I thus invite you to read what they have to say and see if you wouldn’t like to follow in their footsteps!?
