ObjectiveAesthetic complications following neurosurgical procedures impact patient quality of life and self-perception. Postoperative temporal hollowing frequently is seen after temporal craniotomy, resulting mainly from atrophy of the temporal muscle. Autologous fat grafting is a tailorable method to correct such approach-related sequelae. We herein present our clinical patient series and discuss pearls and pitfalls of this method.MethodsIn this retrospective single-center study, correction of postoperative temporal hollowing using autologous fat grafting was performed in 16 patients. Temporal tissue thickness ratio was measured using magnetic resonance tomography images to visualize the graft. Patients, plastic surgeons, and neurosurgeons evaluated the results independently using the herein presented scale.ResultsThe mean interval between the neurosurgical procedure and fat grafting was 62 months. A mean volume of 11.5 mL of autologous fat was injected in an average of 2.5 sessions after initial rigottomy. Temporal tissue thickness was significantly augmented at a mean of 2.2 years after the operation (mean 0.71 ± 0.25, range 0.43-1.1; P = 0.0214) as compared with the preoperative finding (mean 0.48 ± 0.1, range 0.32-0.6). Patients were more satisfied with the results than were surgeons, reflecting the significant impact of the deformity on patient self-esteem.ConclusionsAutologous fat grafting is a valuable method for correcting postoperative temporal hollowing that provides stable results, high patient and surgeon satisfaction, and can be tailored to the patient's individual needs. It should not be considered a merely aesthetic operation but an important rehabilitation step towards restoring the patient's quality of life.Copyright © 2022 Elsevier Inc. All rights reserved.
