Associates in teaching are medical professionals from other countries, which have partaken in courses and workshops that I have hosted or participated in through the years in South Africa. This is by no means the complete list. There are many of them.

These doctors are internationally recognized for their contribution in the field of otology, neurotology and skull base surgery. They have all made their mark especially where it concerns teaching. All of these associates have published in international recognized scientific medical journals and have either written, edited or contributed towards textbooks.

I have had the opportunity to meet them at different occasions abroad, either at meetings, courses, workshops or congresses They have all made a lasting impression on me and have influenced my career in one or other way. I decided to invite and bring them to South Africa to share their expertise with us. Some of these associates have returned on more than one occasion and the others have indicated that they would like to visit again. A few have even been invited afterwards to our national South African ENT congress and have become honorary members of our society.

I am grateful for the ways that they have given advise and helped me formulate the programs that we offered at our meetings, courses, workshops and congresses.

Some of my more challenging patients have had the opportunity to either consult with them abroad or in South Africa. I have also had the opportunity to perform surgery with them and some have helped me with difficult surgical cases in South Africa.

It is a privilege to know such people, to have worked with them and to have presented courses with them. I have made good friends and shared nice experiences. I have even climbed Table Mountain with one or two of them!

It is comforting to know that consultation and advice is only an email or telephone call away.
