sural nerve for facial reanimation
DESCRIPTION
make three grafts out of one sural nerveTRANSCRIPT
Diagnosis?
Chronic Unilateral facial palsy
Facial reanima7on
One stage
Two stage
Three stage
Two/three stage
nerve gra=
hypoglossal (ipsi)
accessory (ipsi)
masseter (ipsi)
sural (cross face)
muscle gra=
pectoralis minor
la7ssimus dorsi
gracilis
serratus anterior
Problem of mass movement
Possible solu7on: 3 independent neuronal inputs combined with 3 neurovascular pedicles of one single muscle
Can 1 sural nerve provide 3 gra=s?
Yes it can! But with how many fascicles?
Some contain more...

Mean number of fascicles was 6,3 at the proximal end (min. 1, max. 20) and 6,7 distal (min. 2, max. 16) in the generated nerve gra=s.
The average number of interfascicular bridges (some of them being very 7ny), that had to be cut in one nerve in order to generate these three nerve transplants, was 15 (min. 6, max. 26).
The measurable length of each gra= was 32 cm in average (min. 19 cm, max. 42 cm).
Thank you!
