Orbital Fat Intentional Exposed Endoscopically

The mystery of orbital fat should not be so intimidating. The surgical mantra for chronic rhinosinusitis is to not expose orbital fat, however in specific instances it is imperative to take down the lamina papyracea to expose the orbital fat. Instances where this would be necessary would be for infections, tumors, orbital decompression as well as others. Specifically in this case, we surgically opened the maxillary antrum and took down the anterior ethmoid air cells. From here, we dissected laterally to the lamina papyracea and opened up the lamina where the orbital fat is exposed. This video shows that when you compress on the orbit the orbital fat moves and is displaced towards the path of least resistance in this case the opened up lamina and hence the fat moves towards the ethmoid air cells (ie medial).
