Imaging Anatomy of the Paranasal Sinuses

Anatomy of the paranasal sinuses on imaging. In this video we'll explore the anatomy of the paranasal sinuses on CT. A good understanding of paranasal sinus anatomy is imperative to understand imaging patterns in rhinosinusitis. Imaging anatomy is complicated by the presence of many anatomical variants. A good understanding of paranasal sinus anatomy is needed to detect predisposing factors for the development of (chronic) sinusitis and to identify possible surgical risks. This presentation was made by dr. Simon Nicolay (UZ Antwerp, Belgium) and dr. Sven Dekeyzer (UZ Ghent, Belgium). 0:00 - Introduction + topics 1:26 - General sinonasal anatomy 3:50 - The nasal cavity 6:29 - The nasal septum 9:05 - Function of the nasal cavity 10:54 - The nasal turbinates 14:42 - The nasal meatus 15:35 - Function of the paranasal sinuses 18:41 - Drainage pathways of the paranasal sinuses 19:34 - The spheno-ethmoidal recess 21:48 - The frontal recess 22:46 - The ethmoid bulla 23:44 - The (ethmoidal) infundibulum 24:07 - The ostiomeatal complex 26:08 - The nasolacrimal system 27:31 - The infra-orbital canal and supra-orbital notch 28:19 - The anterior and posterior superior alveolar canals 29:19 - Anatomic variants 30:21 - Nasal cavity variants 30:37 - Septal deviation 33:32 - Septal defect 35:09 - Concha bullosa 37:12 - Paradoxical middle turbinate 38:24 - Olfactory Fossa 39:30 - Keros classification 42:14 - Sphenoid sinus variants 43:02 - Sphenoid sinus pneumatization 44:22 - Sphenoid skull base pneumatization 47:15 - Vidian canal protrusion / dehiscence 48:18 - Optic nerve and carotid canal protrusion / dehiscence 49:41 - Sinus septum insertion on the carotid canal 51:27 - Ehtmoid cell variants 51:58 - Ethmoid bulla 53:08 - Agger-Nasi cell 53:45 - Frontal recess cells 55:14 - Haller cells 56:18 - Supra-orbital air cells 1:00:20 - Onodi cells 1:03:40 - Lamina papyracea 1:04:17 - Adherent uncinate process 1:05:24 - Key Messages 1:06:24 - Anatomic variants that (might) narrow the sinonasal outflow tracts 1:06:54 - Anatomic variants that (might) pose surgical risks 1:10:07 - References and word of thanks to dr.
