Facial sling have been used traditionally in plastic surgery for treatment of facial nerve palsy. Slings can be used either in dynamic or static forms depending on the damage and type of function required. It is commonly used for upper eyelid and oral commissure. Use of static sling for lip is a well known method to maintain the competency of commissure in case of facial nerve palsy. Other conditions where facial sling is used are irreparable facial nerve injury or facial nerve resection as a part of extirpative surgery. Problem faced by patients with complex lower face reconstruction is deviation of oral commissure and drooping of saliva due to significant removal of lip tissue, bulk of the flap, effect of gravity and downward traction forces acting on the flap leading to downward pull or scar contractures. Through this article we highlight the prophylactic use of facial sling during reconstruction of complex lower face defects following cancer to prevent these complications.
