D. Cranial nerve XII-to-VII crossover techniques are indicated within the first 2 years after the onset of paralysis.
E. Cranial nerve XII-to-VII crossover will improve facial function after 1 year to the House-Brackmann score 2

1294) Which of the following findings will have a confirmed BENEFIT after rhinoplaty by the use of perioperative administration of multiple-dose of steroids?

A. 12
B. 18
C. 24
D. 36

1296) The drawing below represents a Hypoglossal-Facial Nerve Crossover. Which of the following statements is FALSE in the represented XII-VII Crossover below.? 

Please note: 
(F red color/Facial Nerve Proximal end),
(F blue color/Facial Nerve distal end)
and H (red color/Hypoglossal nerve.
