ABSTRACT

Objective:To explore the effect of autologous fat transplantation based on the fine anatomy of the female perineum and aesthetic standards.Methods:From June 2015 to September 2020, 25 female patients with perineal cosmetology requirements in the Department of Plastic Surgery, the Fourth Affiliated Hospital of Harbin Medical University, aged from 28 to 55 years, with an average of 33.7 years. 50-80 ml of the patient's autologous fat were collected and filled according to the perineal anatomy and aesthetic standards. Postoperative anti-inflammatory treatment was implemented and sexual life was forbidden for 2 weeks.Results:25 patients were satisfied with the filling effect immediately after operation. Follow-up for 7 days, 1, 3, and 6 months after operation, 20 of 21 cases underwent pudendal filling operation were very satisfied with the postoperative morphology, and 1 case was less satisfied. Among the 20 cases underwent vaginal filling and labia major filling, 17 cases were very satisfied with the postoperative morphology, 2 cases were satisfied after the operation, and 1 case was less satisfied. Of the 10 cases underwent vaginal and G-spot injection, 6 cases were satisfied after the operation. The morphology was very satisfactory, 2 cases were more satisfactory, and 2 cases were less satisfactory. According to a survey of 25 cases of postoperative sexual life satisfaction, 19 cases (76%) had a significant improvement in their conscious sexual life, 3 cases had a more obvious improvement, 1 case had less improvement, and 2 cases had no conscious improvement.Conclusions:The autologous fat injection based on the fine anatomy and aesthetics of the perineum can significantly improve the aesthetic appearance of the perineum.

ABSTRACT

BACKGROUND: The degradation speed of biological materials is critical for the clinical use of guided bone regeneration.The partial biological characteristics and treatment efficacy of concentrate growth factor (CGF) fibrin have been explored preliminarily, but its degradation properties have not yet been reported.OBJECTIVE: To explore the degradation properties of CGF fibrin and platelet-rich fibrin (PRF) in artificial saliva and compare the degradation speed of these two biological products.METHODS: Ten volunteers were selected, and 18 mL of venous blood from each volunteer was extracted and stored in two vacuum blood collectors. The blood samples were then placed into the drum of the Medifuge centrifugal acceleration machine, to separate CGF fibrin and PRF specimens following the preparation process, respectively. Both CGF fibrin and PRF specimens were respectively made into bulk and membranoid, and were then immersed in artificial saliva under 37 ℃. The mass of the bulk specimens and area of the membranoid specimens were measured regularly, and the degradation processes of CGF and PRF were recorded. The degradation curves were drawn to compare the degradation speed of CGF fibrin and PRF.RESULTS AND CONCLUSION: The mass of CGF fibrin and PRF showed no significant difference at the 5th day (P >0.05), while the mass of CGF fibrin was higher than that of PRF at the 3rd, 4th and 6th days (P < 0.05). The residual area of CRF was significantly larger than that of PRF at posttreatment 1-6 days (P < 0.05). To conclude, the degradation speed of bulk or membranoid CRF is slow than that of PRF in artificial saliva. The higher the fibrin content is, the slower the degradation ability is, indicating the strong bioreproductive function.
