Maxillofacial Trauma I Flashcards
etiology of maxillofacial trauma in pediatric population
falls
etiology of maxillofacial trauma in children and adolescents
- sports and playground
2. child abuse
what percent of physical trauma from abuse seen on children and adolescents occur in the head and neck?
50%
etiology of maxillofacial trauma in adult population
- interpersonal violence
- moter vehicle collisions
- sports injuries
- work-related injuries
what percent of MVC (motor vehicle collisions) survivors have facial injuries?
50-70%
when does maxillofacial examination occur?
after Advanced Trauma Life Support (ATLS) has been completed and the patient is stabilized
evaluation of maxillofacial trauma
- immediate assessment
- H&P
- radiographic exam
- assessment
- plan
extraoral mandibular exam includes what?
- palpation inferior border and TMJ
- ROM and excursive movements
- V3 status
intraoral mandibular exam includes what?
- floor of mouth hematoma
- malocclusion
- alveolus
- teeth
what is included in the radiographic exam of the mandible?
- panorex
- CT scan
there’s other radiographs you can take but these are the two Dr. Eman wants us to know
floor the the mouth hematoma is pathognomonic for what?
symphyseal fracture (symphysis of mandible fracture)
tx of intrusion
- compression fracture of alveolus to accommodate new postion
- metallic sound upon percussion
- allow passive eruption of deciduous teeth
- orthodontic traction
- stabilize 2-3 months
tx of extrusion and lateral displacement
- reposition tooth fully at socket
2. splint for 1-3 weeks
goal of tx for avulsed tooth
maintain periodontal attachment
T/F: you should scrape or sterilize the roots of an avulsed tooth
false
physiological movement of avulsed teeth allows what?
fibrous instead of osseous attachment of the root to the alveolar bone
what can you use to transport avulsed tooth?
- saliva
- saline
- milk
- Hank’s solution
- ViaSpan
which dentoalveolar injury has the worst prognosis? 2nd worst?
intrusion then lateral displacement
tx of avulsed tooth with OPEN apex <2 hours after the the accident
- replant immediately if possible
- transport in Hanks or milk (good for 30 minutes)
- doxycycline 1 mg/20ml for 5 minutes
- L.A., socket irrigation, tetanus, abx
- replant
- splint for 7-10 days
- apexification (CaOH)
tx of avulsed tooth with CLOSED apex <2 hours after the the accident
- store in Hank’s solution for about 30 minutes
- replant
- splint for 7-10 days
- perform endodontic cleansing and shaping of canal at time of splint removal
- fill canal with CaOH (6-12 mo)
- perform final gutta-percha obturation (~6-12 mo)
tx of avulsed tooth >2 hours after the the accident
- replant immediately if possible
- transport in Hanks or milk (30 minutes)
- bathe tooth in sodium hypochlorite for ~30 minutes vs manual debridement of periodontal ligament
- perform extra-oral RCT
- bathe tooth in citric acid (~3 min)
- bathe tooth in 1% stannous fluoride (~5 min)
- transfer to 1 mg/20mL doxycycline bathe for 5 min
- L.A., socket irrigation, tetanus, abx
- replant
- splint for 7-10 days
how long should you stabilize mobile teeth?
3-4 wks
how long should you stabilize displaced teeth?
3-4 wks
how long should you stabilize root fracture?
2-4 months
