Treating defective damage of facial nerve with great auricular nerve grafting covered by pediculated fascial tube

Objective To study the curative effect of grafting great auricular nerve with pediculated fascial tube in defective damage of facial nerve.Method All the patients in the study were treated by grafting great auricular nerve which was covered by pediculated fascial tube near facial nerve trunk.Result The 3 otogenic fascial paralysis patients had grade III recovery of facial nerve function(30% ～ 38% ) 2.0 to 2.5 years after the nerve grafting operation; 2 post- traumatic facial paralysis patients had grade II recovery of facial nerve function (69% ～ 71% ) 2.5 to 3.5 years after the nerve grafting operation.Conclusion The grafting of pediculated fascial tube surrounded great auricular nerve can provide a biological environment with excellent blood supply for the plerosis and regeneration of nerves and can accelerate the functional recovery of nerves after the nerve grafting.
