Imaging Anatomy of the Paranasal Sinuses

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. 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.
