  1. 5 ways to prevent complications of surgery are
    .
    • Medical History
    • Adequate Radiographs
    • Prep of a surgical plan
    • Pre-op and Post-op instructions
    • Adherence to basic surgical principles
  2. Adherence to basic surgical principles includes
    C
    C
    A
    A
    H
    D
    • Clear visualization and adequate access (lighting, suction, tissue reflection)
    • Controlled force
    • Asepsis
    • Atraumatic handling of tissues
    • Hemostasis
    • Debridement
  3. What is the most common dentoalveolar surgery injury and what are two causes of it?
    • Soft tissue injuries
    • Caused by inadequate attention and excessive force
  4. Abrasions and burns can be caused by rotary instruments and excessive retraction. What are 2 steps you can do in the management of abrasions and burns, and how long of a healing period can you tell the patient to expect?
    A
    S
    • Antibiotic topical ointment
    • Suture if necessary
    • 5-10 days healing
  5. Situation: you have not followed principles of controlled force and attention and you slipped with the straight and periosteal elevators during surgery, puncturing soft tissue. Bleeding resulted.
    What is your first step?
    Should you suture the wound closed or let it heal by secondary intention?
    • 1st step: apply pressure to achieve hemostasis
    • No sutures; let heal by secondary intention
  6. Most likely areas for Alveolar bone fracture include:
    Buccal cortical plate of m____ canine
    Buccal cortical plate over m___ m____, particularly the __ m___.
    Portions of the f____ of m____ ______
    M___ t______
    ______ bone of the _______ incisors
    • buccal of max canine
    • buccal of max molars, particularly 1st molar
    • floor of maxillary sinus
    • maxillary tuberosity
    • labial bone of mandibular incisors
  7. Excessive force with forceps obviously can lead to inuring osseous structures. What 4 factors of the patient and/or their anatomy predispose the surgery to osseous injury?
    • Proximity of roots to the sinus
    • widely divergent roots
    • thick labial cortical bone
    • old age of patient means less flexible aveolus
  8. In preventing fracture of large portions of cortical bone what are two factors before the surgery starts, and two principles of the surgery that help prevent fracture?
    • PreOp: radiograph and clinical assessment
    • Surgery: avoid excessive force
    • Perform open extraction and/or section teeth
  9. What factor determines if fractured alveolar bone should be saved?
    if it is attached to the periosteum should be saved, if not, discard
  10. An Oro-antral communication can be diagnosed by a nose blowing test. What are two possible outcomes of and oro-antral communication?
    • Maxillary Sinusitis
    • Oro-antral fistula
  11. Name the 3 factors that determine the probability that either a sinusitis or oro-antral fistula will occur.
    • SIZE of the O-A communcation
    • Previous infection (sinus or dental)
    • Management of the exposure
  12. If an Oro-antral communication is less than ___ mm no additional surgery is needed
    3 mm
  13. In addition to the usual sinus precautions (no sneezing, straws, smoking, nose blowing), what additional steps of management should you do for a OA communication 3-6mm?
    Hint: meds and clotting
    • Sinus Meds: Abs (pen, or erythromycin)
    • nasal spray (Afrin)
    • oral decongestant (Actifed)

    Assure clot by using gel foam, or avitene, surgicel, or topical thrombin
  14. For OA communication greater than 6 mm what additional step must occur?
    Flap procedure
  15. A fractured mandible during oral surgery usual occurs during removal of _______ with excessive force of _____ (instrument)
    impacted 3rds, elevator
  16. The most commonly displaced root during extraction is of a _____ _______, so beware of apical pressure.
    maxillary molar
  17. Under what criteria may a displaced root be left in the sinus?
    • less than 3mm
    • no history of sinus or dental infection
  18. Which nerve has the worst prognosis if injured?
    Lingual
  19. Name the 5 drug categories a patient can be using that potentiate post - op bleeding
    AAAAB
    • Aspirin
    • Anti-coagulants
    • Alcohol
    • Anti-cancer drugs
    • Broad-spectrum antibiotics
  20. After extracting the tooth, what 3 things can you do to minimize post op bleeding?
    • Remove granulomatous tissue
    • Smooth sharp bony spicules and edges
    • Inspect wound for any bleeding arterioles
  21. List 4 hemostatic agents available to use in the OMFS clinic
    • Gel foam
    • Surgicel
    • Topical Thrombin- converts fibrinogen to fibrin
    • Avitene
  22. PT measures _____ coagulation while PTT measures ____ coagulation.
    • PT extrinsic
    • PTT intrinsic
  23. Von Willebrands disease is characterized by a deficiency of factor ____
    VII
  24. _________ is bleeding into adjacent soft tissues, seen more in elderly.
    Ecchymosis
  25. Two possible causes of wound dehiscence include _______ soft tissue flap and _____ under _____.

  26. Dry Socket (Alveolar Osteitis) usually develops on the ___ or ___ post operative day. The most common site for dry socket is ___.
    • 3rd or fourth.
    • mand. 3rd molar
  27. The three phases of informed consent are:
    D
    W
    D
    • discussion - the specific problem, tx, side effects, anesthesia, tx alternatives, etc
    • written consent- given in patients language if don't speak english
    • documentation in the patients chart
