Sometimes it is the small details that make big differences for patients: this 37-year-old patient suffers from incomplete facial nerve palsy. Due to the muscular atrophy of the orbicularis oris (mouth ring) muscle, the lack of volume of the left lower lip led to an asymmetry of the lip area. After a single injection of autologous fat from the lower abdomen and the resulting increase in volume, a significant improvement in symmetry was achieved. The patient was highly satisfied and significantly increased his self-esteem.
