Efficacy of tissue gradient difference principle in repairing over-wide eyelid fold after double eyelid plasty / 中华医学美学美容杂志

Objective:To explore the effect of the principle of tissue gradient difference in repairing the over wide eyelid fold after double eyelid operation by incision.Methods:From July 2019 to July 2020, we applied the principle of tissue gradient difference to 30 cases (a total of 60 eyes; age ranging 20-35 years with mean 30) of female patients with excessively wide eyelids after incision double eyelid surgery needing a repair. All cases were from the Plastic Surgery Department of Sichuan Provincial People＇s Hospital. The difference in tissue gradient was manifested as the difference in thickness, texture and tension of soft tissues such as the skin above and below the double eyelid line and the orbicularis oculi muscle.Results:Satisfactory evaluation results showed in a total of 30 patients with 60 eyes, 95.0% ( n=57) were satisfied, and 5.0% ( n=3) were dissatisfied. Two of the patients received the second repair due to the inconsistency of the double eyelid width after correction. One patient obtained satisfactory double eyelid morphology after the second repair, and the other patient obtained satisfactory double eyelid morphology after the third repair. Evaluation results of double eyelid morphology showed that it obeyed a normal distribution by analyzing the difference between preoperative and postoperative double eyelid morphology scores. The results of paired t test showed that the double eyelid morphology was significantly improved 6 months after operation compared with preoperative, and the difference was statistically significant ( t=15.86, P<0.01). Conclusions:The principle of tissue gradient difference guides the repair of double eyelid width that is simple and easy, the effect is good, and it is worth applying.

Mechanical and biodegradable properties of absorbable hydroxyapatite/poly-DL-lactide screws / 中国组织工程研究

BACKGROUND:Through compounding hydroxyapatite and poly-DL-lactide, the mechanical properties, physical and chemical properties of the implants can be enhanced. OBJECTIVE:To detect the effect of hydroxyapatite/poly-DL-lactide composite internal fixation screws in canine femoral condyle cancel ous bone fracture repair. METHODS:Forty-two beagle dogs were operated to bilateral femoral condyle fracture models. The left side was fixed using hydroxyapatite/poly-DL-lactide screws as experimental group;while the right side was fixed with pure poly-DL-lactide screws as control group. After 2, 4, 8, 12, 24, 36 and 48 weeks, conditions of fracture were observed using X-ray, femoral and screw specimens were observed histopathological y, and the bending strength and the average molecular weight were detected. The biological absorption rate, intensity decay rate and biodegradation rate were calculated. RESULTS AND CONCLUSION:After 2-48 weeks, bilateral fractures were fixed wel and new bone grew wel , but the biological absorption rate of the screws in the experimental group was lower than that in the control group (P ≤0.01). In the first 2, 4 weeks, the bending strength of the experimental screws was higher than that of the control screw (P ≤0.05), but the biodegradable speed was slower in the former one (P ≤ 0.05 or P ≤ 0.01). The pathological changes were similar in the two groups. After 48 weeks, the fractures were healed and bone tissue reconstruction was completed. Compared with the pure poly-DL-lactide screws, the hydroxyapatite/poly-DL-lactide composite internal fixation screws have better fixation effects, biocompatibility, mechanical properties and biodegradability.
