OMSITE STUDY GUIDE QUESTIONS AND ANSWERS
SET A+
✔✔Albumin (long term nutrition), pre-albumin (short term nutrition) - ✔✔Labs to show
nutritional status
✔✔Condylar sag- leading to malocclusion - ✔✔Most common complication in IVRO that
was not plated or wired
✔✔25% of sleep cycle (obstructive events in OSA occur during stages III, IV, and REM
which are the deepest) - ✔✔What is true of REM sleep?
✔✔2 x 5cm (or up to 4 x 7) due to difficulty closing donor site defect
Blood supply = infraorbital artery if flap based superiorly and facial/labial artery if based
inferiorly - ✔✔Size limitation of the nasolabial flap and why
✔✔Pivot point of the flap will rest in line with the real of greatest extensibility/laxity -
✔✔Rhomboid flap know design and relation to RSTL
✔✔T- lymphocytes, Langerhans cells - ✔✔What are the cells related to lichen plants?
✔✔Watch for 6 months- recurrence rate of 7% with clear margins, 20% with positive
margins. - ✔✔You excise a granular cell tumor and margins come back "very close"
what is the next step
✔✔Can preserve the nerve (not in a neurofibroma) - ✔✔Treatment of Schwannoma (vs
a neurofibroma)
✔✔Colchicine (chronic control), corticosteroids (acute control) - ✔✔Primary treatment
for Behçet's disease
, ✔✔Symblepharon, leading to ankyloblepharon (corneal scarring and blindness
eventually) - ✔✔What is the appearance of pemphigoid of the eye
✔✔Monochromatic means that the light must be composed of rays of the same
frequency, all of the peaks and troughs line up (coherent) and all of the rays travel in the
same direction forming the purest form of light - ✔✔What is a monochromatic laser and
what does that mean
✔✔Excision by lobectomy or sialoadenectomy. Recurrences are common so excise
with margin of normal tissue - ✔✔Small pleomorphic adenoma of superficial parotid
treatment
✔✔Central DI - ✔✔Deficiency ADH secretion- hypernatremia, low urine Na, high UOP.
Tx: DDAVP
SIADH: excessive ADH and hyponatremia, Na in urine. Tx: water restriction
✔✔Superoxide dismutase - ✔✔Superoxide into oxygen and hydrogen peroxide
✔✔What is extremely sensitive to free radicals in the TMJ - ✔✔Arachidonic acid
✔✔T1 weight MRI lose (release) energy via: - ✔✔Z-axis, longitudinal (labels fat brighter
than water)
T2 = transverse relaxation time and labels water bright than fat (T2 = H2O)
✔✔Submucosal vestibuloplasty - ✔✔A postoperative stent is essential. One can expect
50% relapse even if a stent is used.
✔✔Treacher Collins - ✔✔Downward slanting eyes, micrognathia, conductive hearing
loss, underdeveloped zygoma, coloboma upper eyelid, aplasia lower lid lashes,
malformed or absent ears, CP
✔✔How long to soak BMP in cell collagen sponge prior to use - ✔✔15 min
✔✔Palatal lesions - ✔✔Malignant:
1. Mucoepidermoid carcinoma
2. Adenoid cystic carcinoma
2. PLGA
Benign:
1. Pleomorphic adenoma
2. Peripheral nerve sheath tumors (Shwannoma, neurofibroma, traumatic neuroma)
3. Lymphoma
