2. Fig. 1
Two incisions are placed on the pre-auricular region of the non-paralyzed side. From each incision, the SMAS plane is dissected blind as the dotted lines indicate.

3. Fig. 2
After the right-handed surgeon introduces an endoscope through the left incision, dissection is continued using a microdissector inserted through the right incision. The pre-auricular skin is hooked, and adjunctive traction of the cheek skin is performed using 3–0 silk thread, since sufficient optic space cannot be attained.

4. Fig. 3
Endoscopic dissection enables visualization of several facial nerve branches. Among these branches, those innervating the zygomaticus major muscle can be found by dissecting the undersurface of this muscle. M: zygomaticus major muscle, N: facial nerve branch.

Recipient facial nerve branches are severed as far distally as possible. V: vessel tape, N: facial nerve branch.
