Dermal-Fat Graft for Facial Contouring in Patients With Craniofacial Microsomia.

Craniofacial microsomia (CFM) is a variable craniofacial malformation, related to the development of the structures originated from the first and second brachial arches, affecting skeletal tissue, soft tissue, and neuromuscular components. In the situation of subcutaneous tissue and chewing muscles hypoplasia, free tissue transfer is a treatment option. Dermal-fat graft allows easy modeling during surgery, volumetric gain and improvement of asymmetry. The aim of this study was to evaluate the facial contour and the percentage of symmetry after the use of dermal-fat graft in patients with CFM, who had already submitted to osteotomies, attended at the Associate Center for Cleft Lip and Palate (CAIF) during 2001 to 2018. For analysis, the authors selected 17 patients who fulfilled the above prerequisites. The symmetry study was done by the analysis of preoperative and postoperative photographs in the Image J software. Two standard points were used: nasal base and upper lip limit. On the nasal base, the preoperative analysis showed a hypoplastic side with a median of 93.00% of the normal side size, rising to 97.78% in the postoperative period. On the upper lip limit, the preoperative analysis showed a median of 87.80% and, in the postoperative period, 98.15%. Analysis of the interaction between the operative moments and the modified Pruzansky classification showed that there were no significant differences between grades. Long-term evaluation demonstrated that the use of a dermal-fat graft for correction of facial symmetry was effective and close to 100%, regardless of the degree of hypoplasia of the patient.
