Mandibular Fractures Flashcards
type of fracture
simple
compound
comminuted
greeenstick
pathological
muscles attached to the mandible
temporalis
masseter
lateral pterygoid
medial pterygoid
when is a bucket handle fracture seen
seen in edentulous mandibles
bilateral parasymphaseal fractures
extra-oral clinical features
pain
swelling
bruising
trismus
cut lip
otorrhoea
anaesthesia/paraesthesia of lip
intra-oral clinical features
haematoma (FOM)
malocclusion
step deformity
gingival laceration
mobility or loss of teeth
radiographic views to be taken
DPT and PA mandible to allow 3D visualisation
what does a delayed presentation cause
increased risk of complications - wound dehiscence, infection, exposure of hardware, non union or fibrous union
who to refer to
maxillofacial surgery
what is an open technique
fracture margins are visualised intra-orally or extra-orally via an incision
why is the open technique preferred
fracture is immobilised to allow a period of healing
what is the closed technique
fracture margins are not directly visualised
example of closed technique
inter maxillary fixation (wiring the jaws together)
why is closed technique generally not used
there is often mobility at the fracture site that can have a detrimental effect on healing
what does the reduction technique do
aligns the bone ends anatomically
what does fixation technique do
prevents movement of the bone margins whilst healing occurs
