Orbital # Flashcards
Ping pong ball causes what fracture?
Blow out #
Pn - ping pong ball just freaks OUT!!! (Always bounces so much!!)
Describe Blow out fracture…?
Here, TG there is fracture if orbital FLOOR…. Caused by a ROUNDED Object striking the eye..
What’s blow IN fracture?
Fracture of Inferior orbital RIM…. (Not floor) ..
There is inward buckling if orbital floor here. That’s why called as Blow IN…
Dx of blow out fracture?
Difficult to CLINICALLY diagnose blow out fracture because of edema that masks any enoptholmos n vertical diplopia…
FORCED DUCTION test of all 4 rectus muscles is a MUST!!
Most accurate Diagnostic aid here…. —– Sagittal CT Scan… and Hypocycloidal Tomograms…
Surgical intervention if Diplopia doesn’t resolve within 2-3 wks of injury…
What’s TEAR DROP Sign? (AKA Hanging drop sign)
In WATER’s projection…. A polypoid mass ( which mainly contains INFERIOR Rectus ) is seen herniating through the Orbital FLOOR into maxillary sinus… The shape of this mass is like a TEAR DROP!! So called so..!!
** Pn – Water - Tear drop..! As simple as that!;
Indication for surgical intervention in Blow out # ?
—– If DIPLOPIA does not resolve in 10 days..
—– a # with LARGE HERNIATION into max sinus
—– Enopthalmos greater than 3mm
—– increase in intraocular pressure on upward gaze
Diplopia after # results due to?
Entrapment of extraocular muscles… Esp INF RECTUS n Inf oblique…
All the following abt NASAL fracture true EXCEPT?
Except —- they may need to be reduced for wks… ( The for wks part not clear.. may be a typo error )
** Here, the # should be reduced within 7 to 10 days..
The other 3 options that r TRUE.. r…
A. Even if minor they may be followed by BILATERAL ecchymosis n facial edema
B. They need not be complicated by traumatic telecanthus
C. They may lead to telescoping of the nasal complex into frontal sinus
Forceps used to reduce NASAL complex # ?
Walsham/Asche forceps
Pn - Ambrose would hv easily gone on to # Waugh’s NOSE!!!!
(ACTUALLY… WALSH, his partner comes here!!) N Waugh for ASHES (Asche)
Radio method to Dx nasal fracture?
True lateral
Pn - NOSE is right at the ctr of face… But Radio method here is exactly OPPOSITE!!! i.e., TRUE LATERAL!!
Facial bone most prone to # ?
Nasal bone
Forceps to reduce tooth bearing portion of upper jaw? Another Q goes like this… “Forceps used for maxillary # reduction?”… ANS for both these Qs… the same…
ROWE’s disimpaction forceps
Forceps to elevate fractured ZYGOMATIC bone??
Bristow’s elevator
Pn - Most famous# of face- ZYGOMATIC bone…! Most famous Cigerrate… - BRISTOL!!
Enoptholmos seen in?
Blow out #
Rx of fresh blow out # of orbit?
Just wait n watch since it’s FRESH…(I can Rm a little bit of RT Sir teaching this!)
If DIPLOPIA doesn’t resolve in 10 days or 2 to 3 weeks… —- Sx
