What drains into inferior meatus?
Nasolacrimal gland
What drains into middle meatus?
2. maxillary- and frontal sinus
What drains into the superior meatus?
Sphenopalatine foramen and posterior ethmoidal cells. NB. Sphenoid sinus opens above the superior turbinate and a bit posteriorly.

Risk of acute sinusitis following.
Nasal vestibulitis
Carrier of S.pyogenes and their skin becomes infected. Tx: prolonged antiseptic/antibiotic ointment. Systemic flucloxacillin if really bad. In children - look for foreign body.
Nose bleed(Epistaxis) - Causes
Young boy with nosebleed, think of:

Blood supply to nose.
Posterior nose-bleeds
10% - main source: Branches of sphenopalatine artery (Woodruff’s plexus)
Anterior nose-bleeds
90% - main source: Kiesselbachs plexus that supply Little’s area. Recieves branches from both ICA and ECA:
Anterior nose bleed - Treatment
Posterior nose bleed - Treatment
Samter’s triad/Aspirin triad
Bronchial asthma + polyps + aspirin sensitivity
