Background: Augmentation rhinoplasty with autologous fat grafting is a useful procedure to meet the demand for facial harmonization in the Asian population. We used this procedure during orthognathic surgery to address inadequate dorsum projection. This prospective study was conducted to determine the fat retention rate in patients undergoing simultaneous autologous fat injection augmentation rhinoplasty and orthognathic surgery. Methods: Nineteen patients were treated with simultaneous bimaxillary orthognathic surgery and autologous fat grafting of the nasal dorsum and tip. The paired t test was used to compare the nasal volumes before and at least 6 months after surgery measured by 3-dimensional computer tomography scans. All measurements were performed twice by the same evaluator at least 2 weeks apart for intrarater consistency. Results: Seventeen patients completed the study. The volume means before and after surgery were 22.3 ± 4.6 cm3 and 23.3 ± 4.7 cm3, respectively, with a mean difference of 1.0 ± 0.3 cm3 ( P < .001). The mean retention rate was calculated to be 50.5% ± 7.0% (range: 40.5%-64.7%). Intrarater consistency was high with a Cronbach α of .97 ( P < .001) and .98 ( P < .001), respectively. Conclusion: This prospective study provides objective graft retention measurements for fat injection augmentation rhinoplasty combined with orthognathic surgery. All patients were satisfied with the results and no complications or additional morbidity was noted in the postoperative course. We consider this procedure to be a safe, reliable, and powerful adjunct to improve the aesthetic results of orthognathic surgery.

BACKGROUND Augmentation rhinoplasty with autologous fat grafting is a useful procedure to meet the demand for facial harmonization in the Asian population. We used this procedure during orthognathic surgery to address inadequate dorsum projection. OBJECTIVE This prospective study was conducted to determine the fat retention rate in patients with simultaneous autologous fat injection augmentation rhinoplasty and orthognathic surgery. METHODS Nineteen patients were treated with simultaneous bimaxillary orthognathic surgery and autologous fat grafting of the nasal dorsum and tip. The paired- t -test was used to compare the nasal volumes before and at least 6 months after surgery measured by 3D CT scans. All measurements were performed twice by the same evaluator at least 2 weeks apart for intra-rater consistency. RESULTS Seventeen patients completed the study. The volume means before and after surgery were 22.3 +/- 4.6 cm3 and 23.3 +/-4.7 cm3 respectively with a mean difference of 1.0 +/- 0.3 cm3 (p<0.001). The mean retention rate was calculated to be 50.5 +/- 7.0% (range 40.5% to 64.7%). Intra-rater consistency was high with a Cronbach α of 0.97 (P<0.001) and 0.98 (P<0.001) respectively. CONCLUSIONS To the best of our knowledge, this is the first prospective study that provides objective graft retention measurements based on computer tomography scans for orthognathic surgery combined with fat injection. All patients were satisfied with the results and no complications or additional morbidity was noted in the postoperative course. We consider this procedure to be a safe, reliable and powerful adjunct to improve the aesthetic results of orthognathic surgery.

Systemic sclerosis (SSc) is a rare systemic autoimmune disease, characterized by progressive cutaneous and internal organ fibrosis. Orofacial manifestations of systemic sclerosis are extremely disabling and treatment options are limited. In this study, we aimed to assess the safety and efficacy of autologous fat grafting in the face of patients with systemic sclerosis. We enrolled 16 SSc patients suffering from facial sclerosis and limited mouth opening capacity. Autologous fat injection ranging from 15 to 40 ml was administered per patient, based on their face morphology. The patients were evaluated at baseline and 3 months after fat injection. Evaluations included mouth opening capacity, mouth handicap in systemic sclerosis (MHISS), Rodnan skin sclerosis score, skin biophysical properties using a sensitive biometrologic device with the assessment of cutaneous resonance running time (CRRT), volumizing and aesthetic effects based on pre- and posttreatment photographs, possible side effects, and global patient satisfaction. Clinical assessment showed autologous fat transfer significantly improved mouth opening capacity and the MHISS and Rodnan score of patients with facial scleroderma (p value <.001). The aesthetic and/or functional results of fat injection were satisfying to about 80% of the patients. The changes in CRRT values were not significant. Our findings support the possible therapeutic role of autologous fat grafting in improving facial scleroderma both in aesthetic and in functional aspects. This trial is registered with IRCT20180209038677N1.
