Introduction
This resource has been created by otorhinolaryngologists for students interested in pursuing postgraduate studies. It provides students with a comprehensive and contextually relevant starting point on their journey. The goal of this project was not to create an all-inclusive and overwhelming wall of text, but rather to provide material that is engageable and may be built upon by the students themselves.
In our own experience, much time was wasted trawling through textbooks and internet sites in an attempt to understand the anatomy and physiology of the head and neck.
We understand that learning is a continual process, and we hope that by using the cranial nerves as a starting point to your journey, that it will provide a scaffold upon which to build your knowledge of discipline specific anatomy and physiology. In addition, whilst we were embarking on our own otolaryngology journeys, we found that studying the anatomy and physiology was often confusing because no context for the importance of the knowledge was provided. We hope that this resource addresses this shortfall.
Approach
We would recommend learning the anatomy and physiology first by learning each of the cranial nerve chapters, then by learning:
The blood supply of the head and neck
The anatomy of the skull base and foramina
The vestibular ocular reflex
Lastly reviewing the cranial nerve chapters with the newly acquired knowledge
Benefit of an online resource
An open access, online resource provides the opportunity for continued improvement of the resource. We value your input, and should you find substantial failings in it, please provide feedback so that your concerns may be addressed. Although we have provided the footprint for the resource, fresh ideas always lead to better outcomes. Our hope is that through YO-IFOS, an individual or group of individuals continue to build upon this.

I started my academic career at the University of Cape Town's Division of ENT (2018-2023). I resigned from that post to pursue an academic career targeted at addressing health inequalities for social justice. I am a director at Hope-Hear, a NPC created to fulfil this purpose through improved access to ENT health services in the early developmental years to optimise cognitive growth in vulnerable populations. This includes providing accessible learning resources. I am affiliated to UCT's Division of Audiology and will be joining Stellenbosch University's ENT Department as an honorary lecturer in 2025.
