Welcome to the Otolaryngology 3D Anatomy Atlas!

ABOUT: Headmirror’s Otolaryngology 3D Anatomy Atlas is an open-access online resource that is designed to enhance surgical case preparation and provide a framework for anatomical and surgical learning for students and surgical trainees. Each chapter is intended to walk the learner through common otolaryngology procedures and can be used as a guide for cadaveric lab dissection or as a concise visual study aid when preparing for surgical cases. 

Within the atlas, each step of a dissection displays a triad of images: 1) a 2D image with annotations and anatomic orientation; 2) a 2D image without annotations; and 3) a 3D image without annotations. The 2D annotated image includes accompanying “key points” that reveal themselves with a mouse hover, or a tap on the dot in the lower right corner if using a mobile device. The 3D image is displayed in stereoscopic format and should be viewed with conventional red-cyan 3D glasses (e.g. here).

In addition to using these images for your own education or reference, we encourage you to use them in your own presentations or share them on social media. If you do, we kindly ask that you retain the attribution statement currently embedded in each image to inform your audience of the original source and to lead others to this free resource.

DISCLAIMER: The information provided here is for educational purposes only and is designed for use by qualified physicians and other medical professionals. In no way should it be considered as offering medical advice. By viewing this atlas, you agree not to use these videos as medical advice to treat any medical condition in either yourself or others, including but not limited to patients that you are treating. Consult your own physician for any medical issues that you may be having.
