Welcome Message

Dear Colleagues,

It is with great pleasure that I announce the upcoming 4th PONS Congress, scheduled to be held in 2026

In response to the overwhelming interest demonstrated by colleagues from across the country and abroad, and in line with our prior commitments, we are proud to organize this fourth edition of the congress, centered around these key objectives:

First, in recent years, the fields of otology and neurotology have witnessed remarkable progress in both diagnostic techniques and medical and surgical treatments. Sharing and discussing these developments will contribute significantly to advancing professional knowledge and clinical practice within our community.

Second, the rapid evolution of technology has introduced a wide range of new therapeutic options. It is essential that we come together to establish a consensus on how best to adapt and implement these treatments in accordance with the unique socioeconomic context of our patient population. Forums such as this congress provide an invaluable opportunity to align our approaches and enhance patient care.

Third ,our young otologists and audiologists deserve a dedicated platform to showcase their outstanding academic contributions and to exchange their innovative ideas. This congress remains the only national gathering of its kind in our country that is specifically committed to encouraging and empowering these bright professionals.

In light of these scientific and clinical advancements, it is our responsibility to remain informed and proactive in updating our practices. Therefore, I warmly invite you to join us, share your insights, and contribute to this important exchange of knowledge.

We look forward to welcoming you to a collaborative, inspiring, and intellectually enriching environment.
