42. Sinus associated Cells

Agger nasi cells: Most anterior of Anterior ethmoidal cells and lie close to frontal recess; can obstruct frontal sinus drainage. HAller cell: Anterior Ethmoidal cell in roof of maxillary sinus/floor of orbit. Haller cells overlooked during surgery can be a source of persistent mucopurulent secretion. Onodi cell:POsterior ethmoidal cell related to optic nerve; identify these cells during FESS to avoid optic N injury

37. Basal Skull Fracture

Most basilar/basal skull fractures are caused by high-velocity blunt trauma such as motor vehicle collisions, motorcycle crashes, and pedestrian injuries. Structures involved: petrous temporaL bone (MC), the external auditory canal, and tympanic membrane. Signs of basal skull fracture Hemotympanum (blood pooling behind tympanic membrane making it appear purple - earliest finding)Cerebrospinal fluid (CSF) otorrhea or rhinorrhea (“Halo” sign is the double ring pattern described when bloody fluid from the ear or nose containing CSF is dripped onto paper or linen)Battle sign (retroauricular or mastoid ecchymosisRaccoon/Panda eyes (periorbital ecchymosis).
