ABSTRACT
Objective:To observe the application and clinical effect of stromal vascular fraction gel (SVF-gel) in local rhinoplasty.Methods:A total of 84 patients with mild nasal root and low bridge were divided into observation group and control group. In the observation group, liposuction with SVF gel extraction plus injection rhinoplasty was carried out; in the control group, liposuction plus injection rhinoplasty was carried out according to the height change of nasal root and bridge, the change of nasal frontal angle, the occurrence of complications and the satisfaction of patients after operation.Results:The 84 patients were followed up for 2 weeks to 24 months. The height of nasal root and bridge increased significantly and the lines were more harmonious. The absorption of the observation group was much lower than that of control group. Except 3 patients in the observation group and 8 patients in the control group, there were different degrees of absorption within 6 months after operation. All patients did not have complications such as fat liquefaction, necrosis, induration and infection in the injection area. Three patients in the observation group were satisfied with the results after reinjection, and one patient in the control group was satisfied with the results after reinjection, three patients were not satisfied with the results, and four patients were satisfied with the prosthesis augmentation rhinoplasty. In the observation group, there were 37 cases of excellent satisfaction, 5 cases of good satisfaction, and the overall satisfaction was 100%; in the control group, there were 20 cases of excellent satisfaction, 15 cases of good satisfaction, 7 cases of bad satisfaction, and the satisfaction was 83.3%. The former was better than the latter.Conclusions:In view of superiorities such as lower complications with long-lasting effect, high fat survival rate and high satisfaction in local augmentation rhinoplasty, SVF-gel injection is especially suitable for patients who cannot accept autologous bone, prosthesis and allograft tissue filler for augmentation rhinoplasty.
ABSTRACT
Objective: To investigate the effectiveness of levator muscle resection combined with Mustarde's double Z-plasty to correct blepharophimosis-ptosis-epicanthus inversus syndrome (BPES). Methods: Between March 2015 and June 2017, one-stage operation of levator muscle resection combined with Mustarde's double Z-plasty were performed on 26 children with bilateral BPES. There were 16 boys and 10 girls with an average age of 7 years (range, 4-14 years). All patients marked the four typical signs of BPES. There were 7 cases accompanied with a low nasal bridge, and 20 cases with amblyopia and strabismus. The length of eye fissure was (19.5±4.5) mm, the width of eye fissure was (2.5±1.6) mm, the diameter of inner canthus was (42.1±6.5) mm, and the muscular strength of levator palpebrae superioris was (5.5±1.3) mm. Results: All the incisions healed by first intention. Twenty-three patients were followed up 2-12 months, with an average of 10 months. Among which, 2 cases were less corrected, 3 cases were over corrected, 6 cases had poor curvature of the eyelid. No eyelid internal and external pronation or keratitis occurred. Amelioration of blepharoptosis and epicanthus was achieved in the other patients, and the double eyelid fold was naturally smooth. At 7 days after operation, the length of eye fissure was (27.2±1.9) mm, the width of eye fissure was (12.5±1.3) mm, and diameter of inner canthus was (29.4±2.6) mm, which were superior to preoperative values ( t=0.127, P=0.042; t=0.341, P=0.029; t=0.258, P=0.038). There was no angular deformity caused by the width and length regressions of eye fissures. Conclusion: The levator muscle resection combined with Mustarde's double Z-plasty can effectively correct BPES and obtain good effectiveness.
