The best situation for repair of the facial nerve is when primary reanastomosis is possible between the transected ends; however, this is an uncommon occurrence in congenital paralysis. In developmental paralysis, a fibrotic remnant of the nerve or total absence of the nerve and traumatic paralysis is often caused by a crush injury rather than transection. Nerve ends may need to be débrided before anastomosis with 8-0 or 9-0 nylon sutures. The primary recommendation today is to use an epineurial repair because suture placement with fascicular or perineurial repair is difficult and may injure the axons. [43] The key factor in neurorrhaphy is reapproximation without tension.
