Lipotranferences in post neurosurgical esthetic defects.

Background: There are numerous procedures in which, beyond adequate manipulation of the temporalis muscle and cranial closure, patients may present bone and muscle defects due to atrophy and consequent facial asymmetry, causing psychological discomfort and functional deterioration. The objective of our work is to combine the knowledge of plastic surgery and apply it to cranial reconstructions with fat transfers in post-neurosurgical patients, analyzing its results. Methods: During the year 2022, 45 fat transfer procedures were performed for the correction of craniofacial defects, of which 29 were female and 16 were male. All had a surgical history of pterional craniotomies and their variants, orbitozygomatic and transzygomatic approaches, with the consequent volume deficit. Results: The procedure was performed on an outpatient basis, with local anesthesia, and in an average time of 30-40 min. The lower hemiabdominal region was used as the donor area, processing the fat using the decantation technique and injecting it into the receptor area at the craniofacial level. The patients tolerated the procedure adequately without intraoperative complications or superadded events. Conclusion: Fat transfer is a minimally invasive, effective, and cost-effective technique that plastic surgery offers us to implement in post-neurosurgical patients, as it achieves natural results that stand the test of time.
