Abstract
We describe the case of a 45-year-old male patient who presented a retractile and painful scar in the nasolabial fold due to trauma which determined partial motor impairment of the mouth movements. We subsequently treated him with autologous fat grafting according to Coleman's technique. Clinical assessments were performed at 5 and 14 days and 1, 3, and 6 months after surgical procedure and we observed a progressive release of scar retraction together with an important improvement of pain symptoms. A second procedure was performed 6 months after the previous one. We observed total restoration of mimic movements within one-year follow-up. The case described confirms autologous fat grafting regenerative effect on scar tissue enlightening a possible therapeutic effect on peripheral nerve activity, hypothesizing that its entrapment into scar tissue can determine a partial loss of function.
Highlights
Medical therapy and close observation are appropriate for those patients with incomplete paralysis, delayed onset of paralysis, blunt trauma to the extratemporal nerve, and injury occurring on the medial to the lateral canthus of the eye [2]

Facial nerve injury can be a devastating injury resulting in functional deficits and psychological distress the nerve is anatomically intact or the injury is limited to the medial portion of a peripheral branch
Summary
Trauma to the facial nerve is the second most common cause of facial paralysis and can result in devastating consequences including ocular complications, impaired speech, feeding difficulties, and inability to convey emotions through facial expression [1]. Autologous fat grafting is a relatively new technique which has been recently adopted to treat various pathologic conditions in reconstructive surgery. We successfully applied autologous fat grafting in the treatment of Arnold neuralgia [6], a chronic headache of cervical origin (both chronic cervicogenic and occipital neuralgia), caused by cicatricial entrapment of the great occipital nerve. We describe the case of a 45-year-old male patient who presented with a scar in the nasolabial fold due to a trauma and consequent partial motor impairment of the mouth movements treated with autologous fat grafting
