Question 10

<p>
Which of the following is true concerning osteocutaneous radial forearm free flap (OCRFFF)? </p>

<p>
</p>

<p>
A. Typical length of bone available is 15cm</p>

<p>
B. Prophylactic plating of the donor radius has nearly eliminated the risk of pathologic radial bone fractures</p>

<p>
C. The reconstructive technique typically involved harvesting 75% of the radial bone&#39;s width with keel-shaped osteotomies on either side.</p>

<p>
D. The most common complication at the donor site is hand weakness or numbness</p>

Answer 10

<p>
B. Prophylactic plating of the donor radius has nearly eliminated the risk of pathologic radial bone fractures</p>

Question 11

<p>
Which of the following is false concerning ear plugs and water intrusion? </p>

<p>
</p>

<p>
A. All earplugs can be expected to have some water intrusion</p>

<p>
B. Vertical head submersion resulted in more water intrusion than horizontal head submersion</p>

<p>
C. Cylindrical moldable sponge plugs appear to have the least water intrusion when compared to moldable silicone and multiflanged plugs</p>

Answer 11

<p>
C. Cylindrical moldable sponge plugs appear to have the least water intrusion when compared to moldable silicone and multiflanged plugs</p>

<p>
It actually appears that moldable silicone and/or multiflanged plugs do best.</p>

Question 12

<p style="text-align: center;">
	<br />
	 </p>
<p>
	T or F?   Cochlear implant users report better voice quality and speech understanding when listening to male talkers because of the lower fundamental frequency of the male voice.</p>

Answer 12

<p style="text-align: center;">
	F.</p>
<p>
	 </p>
<p>
	Cochlear implant users often report differences in voice quality and/or speech understanding across gender and talkers.  However, the individual CI user preference varies between male and female talkers.</p>

Question 13

</p>

<p>
A. Increase in IL-4, IL-5 and IL-13</p>

<p>
B. Increase in IgG2 antibodies</p>

<p>
C. Decrease in TGF-b and IL-10</p>

<p>
D. Increase in serum eosinophils</p>

<p>
E. Decrease in Th2 / Th1 ratio</p>

Answer 13

<p>

| E. Decrease in Th2 / Th1 ratio</p>

Question 14

<p>
<br></br>
Which of the following statements regarding tissue expansion devices is false?</p>

<p>
</p>

<p>
A. The standard tissue expander is composed of a silastic reservoir, and injection port and connecting tubing</p>

<p>
B. The rectangular shape device will achieve the least gain in surface area.</p>

<p>
C. The size of the expander base should be 2.5-3 times the size of the defect to be closed.</p>

<p>
D. The donor site should be an area adjacent to the defect with tissue similar to that being replaced.</p>

<p>
E. Tissue expander will stimulate proliferation of blood vessels in the expanded area.</p>

Answer 14

<p>
B. The rectangular shape device will achieve the least gain in surface area.</p>

<p>
</p>

<p>
Several types of tissue expanders exist, based on shape, size, and type of filling valve. Expanders can be standard, customized, anatomic to the donor site, or differential in fill volume to provide tapering of tissue. In terms of shape, they follow three basic patterns: round, rectangular, and crescent.</p>

<p>
</p>

<p>
The more commonly used include the round and rectangular types; crescent-shaped (and croissant) prostheses, originally developed to minimize dog-ears at the donor site, have fallen out of favor as it has been recognized that the added tissue gained with rectangular expanders may increase the choices possible for flap design (i.e., use of transposition flaps)</p>
