Reconstructive

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.
The circle represents the anastomosis XII-VII).

A. XII-VII anastomosis without interposition nerve graft is the most common nerve transfer technique used for re-innervation of a long-standing facial nerve paralysis
B. The indicated time for a XII-VII crossover nerve transfer technique is a facial nerve paralysis of more than 2 years
C. The electromyography (EMG) shows fibrillations with intact motor endplates
D. If the motor endplates are not viable (electrical silence in the EMG) will preclude the nerve anastomosis
E. There is no loss of sensation in the auricular region
