Spread of Infection Flashcards
if an infection in the maxillary jaw perforates the bone above the insertion of the buccinator what happens and in what space
facial swelling and spread of infection into the buccal space
why is infection less likely to spread palatally
the bone is more dense
if infection in maxillary jaw perforations below the insertion of the buccinator what happens
infection drains into the mouth
if an infection in the maxillary jaw spread upwards into the maxillary sinus what condition will the patient experience
sinusitis
if an infection in the mandibular jaw perforates the bone above the mylohyoid line what space does it go into
sublingual space
if an infection in the mandibular jaw perforates the bone below the mylohyoid line what space does it go into
submandibular space
where is it more common for infection to spread in the posterior and anterior mandible
posterior = lingual
anterior = buccal
where would an infection in a mandibular premolar most likely go
sublingual space
where would an infection in a mandibular molar most likely go
submandibular space
if the infection goes posterior into the masticatory spaces what happens to the muscles
spasm giving trismus
once the infection has spread to the masticatory spaces what spaces can it go to from there
pharyngeal spaces
retropharyngeal space
prevertebral space
how do mandibular infections spread to the cavernous sinus
spread to infratemporal region and then pterygoid venous plexus which corresponds with brain and cavernous sinus
how do maxillary infections spread to cavernous sinus
spread to infraorbital space where the veins are valveless and then flow back to the cavernous sinus
where do upper anterior teeth spread infection to
lip
nasolabial region
lower eyelid
where do upper lateral incisors spread infection to
palatal
