Describe the sinus drainage
|
All sinuses drain into Middle Meatus (Frontal/Maxillary/Anterior Ethmoidal drain to semilunar hiatus (in middle meatus) and middle ethmoidal to ethmoidal bulla (also middle meatus))
, except for: - Sphenoid sinus to sphenoethmoidal recess - Posterior ethmoidal air cell to Superior meatus - (Nasolacrimal duct to inferior meatus) - Eustachian tube/ auditory tube to nasopharynx. |
