odontogenic disease of the maxillary sinus Flashcards
most cmmon sinus disease
rhinosinitis
waht are the 4 paired nasal sinuses
maxillary
ethmoid
frontal
nasal
which sinus do all 4 pairs drain to
the nose
nasal cavity
function of the paranasal sinus
regulate intranasal pressure
increase SA for olfaction
humidfy and warm air
lighening the skull
resonance
absorb shock
developemtn of facial growth
penumatixiation
air cavities developing within the bone
waht is the superior border of hte ehtmoid sinus
anterior cranial fossa
lateral border of the ethmoid sinus
medial wall of the orbit
waht is the function of the ethmoid sinus
connects the frontal sinus to the maxillary sinus
sphenoid sinus froms from
forms from evagination of
nasal mucosa into
sphenoid bone
waht types of walls do the anterior wall of frontal sinus and the posterior wall
thick anterior wall
thin posterior wall
waht is the most common sinus you get sinusitis
maxillary sinus
waht is the roof of the maxillary sinus
the floor
orbital floor is froof
floor is alveolar process of the maxilla
where does drainage of the maxillary sinus go to
ethmoidal infundibulum
which tooth does penuamtization of maxillary sinus usually surround around
max 1st M
3 factors for normal sinus function
sinus drainage
ciliary motility
quality of nasal secretions
most important site of sinus drainiang is
middle meatus
[lateral to the middle tubinate]
pstiomeatal complex is the area compirinsg draning of ?
frontal
maxilalry
ethmoid sinuses
___ and ___ blocks the drainage of the sinus and gets diseases and symptoms
mucosal swelling
obstruction
swelling of the sinuses and most common reason for sinus diseas
edema - allergens
Sinus membrane aka ___ membrane
schniederian
waht type of epithelium is the sinus membrane aka schniederian
respiratory epithelium
on the exam is the slide
diagnosis - physical exam
MOST RELIABLE INDICATOR OF ACUTE SINUSITIS IS PRESENCE OF MUCOPURULENT SECRETIONS IN THE MIDDLE MEATUS [LATERAL TO THE MIDDLE TURBINATE]
MOST RELIABLE INDICATOR OF ACUTE SINUSITIS IS PRESENCE OF MUCOPURULENT SECRETIONS IN THE MIDDLE MEATUS [LATERAL TO THE MIDDLE TURBINATE]
types of radiography we use
- PA radiograph
- panoramic - get a general idea of waht it looks like, generally should be filled with air so looks black
- Plain film - outdated
- computerized tomography (CT) scan - air looks black and those that look whitish grey = fluid
- best for chronic sinusitis - MRI
MRI
good ___ detail and poor ____ resolutiona
good soft tissue
poor bony
