NCT05369273

Brief Summary

The objective is to show the superiority of the PRP + microfat (MG) mixture compared to microfat alone, in the filling of large subcutaneous depressions of the face and skull. The investigators chose to study the post neurosurgical sequelae after removal and reinstallation of the cranial flap, with, for example, damage to the temporal muscle and asymmetry of the temples or sinking of the cranial flap
