You are extracting a maxillary third molar & you displace it into the sinus & get
profuse bleeding. Where is the bleeding coming from? Answer - a. Posterior
Superior Alveolar Artery
Best way to close an oro-antral fistula from a 1st molar? Answer - a. 1-4mm
usually heals on ownb. Buccal Advancement
Indications for Buccal Fat pad closure of O-A fistula, & how it heals. Answer - a.
Defects 7 mm and biggerb. Reepithelializes in 2-4 weeks
A pediatric patient presents to our office 2 weeks following trauma to a
primary centralincisor. The tooth is now discolored, but otherwise
asymptomatic. What is your treatment? Answer - a. Observe
What type of mandibular fracture poses the greatest risk of airway
obstruction? Answer - a. Bilateral angle fractureb. Bilateral parasymphysis
fracture - not an option on the exam
Child bitten by a dog 3 days ago, now infected, what is the most likely
organism? Answer - a. Pasturella multicedinsTimely and copious irrigation with
normal saline or Ringer's lactate solution may reduce the rate of infection
markedly. Injection of the tissue with irrigant solution should be avoided,
because this can spread the infectionPuncture wounds, wounds that appear
clinically infected and wounds more than 24 hours old may have a better
outcome with delayed primary closure or healing by secondary intention.5,6
,Some physicians close wounds that are less than eight hours old and wounds
located on the faceprophylactic antibiotics for three to seven days is
appropriate for dog bite wounds, unless the risk of infection is low or the
wound is superficial. If frank cellulitis is evident, a 10- to 14-day course of
treatment is more appropriate. Amoxicillin-clavulanate potassium (Augmentin)
is the antibiotic of choice for a dog bite. For patients who are allergic to
penicillin, doxycycline (Vibramycin) is an acceptable alternative, except for
children younger than eight years and pregnant women. Erythromycin can also
be used, but the risk of treatment failure is greater because of antimicrobial
resistance
Patient with Hamman's Sign following MVA, what type of injury? Answer -
Tracheo-bronchial tree injuryis a crunching, rasping sound, synchronous with
the heartbeat,[3] heard over the precordium in spontaneous mediastinal
emphysema.Hamman's crunch is caused by pneumomediastinum or
pneumopericardium, and is associated with tracheobronchial injury due to
trauma, medical procedures (e.g., bronchoscopy)
8. When you bite on your anterior teeth describe the forces applied over an
angle fracture? Answer - Tension at the alveolus, compression at the inferior
border
9.Patient has flaccid elbow & wrist reflex, but normal triceps reflex following
MVA, what is the level of C-spine injury? Answer - a. C 5-6 (triceps is C 6-7).
waiter tipTraction or Tear of the upper trunk C5-C6 roots.infants-lateral traction
on the neck during deliverAdult traumaMuscle deficite with Deltoid,
Supraspinatus, InfraspinatusKlumpake Palsyy Truction or tear lower trunk c8-
T1Total claw hand ( loss of wrist flexion
. Bone-bone contact & compression across the fracture site Answer - a. Bone-
bone contact & compression across the fracture site
, What type of plate & screw fixation provides the most stable fixation? Answer
- Neutral zone
i. However, this is not possible in the mandible, since the neutral zone is in
direct line w/ the IAN
What is the thickness of the superior tarsal plate? Answer - 10 mm
The tarsal plates are composed of dense fibrous tissue and are responsible for
the structural integrity of the lids. Each tarsus is approximately 29 mm long and
1 mm thick. The crescentic superior tarsus is 10 mm in vertical height centrally,
narrowing medially and laterally
What is the position of the upper eyelid, at primary gaze, in relation to the
limbus Answer - 2-3mm inferior
The normal resting position of the upper lid is 2 mm below the junction of the
superior cornea with the sclera, and that of the lower lid is at the junction of
the inferior cornea with the sclera
Nerve supply of the eyelids
The eyelid is supplied by three cranial nerves (III, V, VII) and sympathetic nerve
fibers.
Aniscoria
status post trauma, what does it mean? Answer - Anisocoria is a condition in
which the pupil of one eye differs in size from the pupil of the other eye.
Yourpupils are the black circles in the center of your eyes. They are usually the
same size. Anisocoria can be caused by several things. You can be born with
this condition or develop it later
a. All the following can be the cause s/p trauma
