nose and paranasal sinuses Flashcards
when do the concha produce the most turbulence
breathing out
blood supply to nasal stuff
internal carotid gives rise to a and p ethmoid arteries. Ext. carotid to sphenopalatine
area where epistaxis is common
littles area or kiselbock plexus near front of nose
septal hematoma
perichondrium separates from septum. Must be drained or can lead to infection and necrosis
what drains into inf meatus
just lacrimal
maxillary sinus drainage
ostia opens into hiatus semilunaris leading to infudibulum b/w orbit inframedial orbit and uncinate process into middle meatus
two space-occupying variations which could easily be surgically removed
concha bullosa and haller cell
where is the most problematic place for septal deviation
nasal valve
course of acute rhinovirus URI
sore throat and fever peak day 2 and gone by day 5. Nasal discharge and cough peak day 2 and continue for two weeks
when are you concerned about bacterial sinusitis or acute viral sinusitis
if symptoms suddenly worsen around one week
most common infectious causes of acute sinusitis
rhinovirus> s. pneumoniea> h. influenzae
chronic rhinosinusitis
inflammation (not infection) lasting more than 12 weeks
how do we measure mucous problems
lund-Mackay score. assigns number to each of the sinuses using CT. No correlation to QOL
where is most of the defensive action taking place
epithelium. mucous, cytokines, recruitment, etc
