Objective: To investigate the clinical effect of diced cartilage in correcting nasal alar base depression after cleft lip surgery. Methods: A retrospective study was conducted in 15 patients of nasal deformity after lip surgery from January 2018 to January 2019. All the patients were taken from autologous costal cartilage to reconstruct the outline of nasal malformation, and the remaining autologous costal cartilage was cut into 0.5-1.0 mm pieces and filled into the basilar lacunar space of the nasal alar by the 1 ml syringe whose anterior needle nipples was removed. The effects of visual images before and after operation were compared and analyzed by Adobe Photoshop CS6 software. The patients were followed up for 6-15 months (mean 10months). The satisfaction and complications of the patients were investigated. Results: The nasal alar base was significantly elevated and the outline of the nasal deformity was improved in 15 patients after operation. The overall effect was satisfactory and no obvious complications were found. No obvious absorption was found in the follow-up. Conclusions The application of diced cartilage to correct the nasal alar base depression after cleft lip surgery was a feasible method with important clinical value. It advanced in taking good use of the remaining cartilage and reducing the damage to both the donor and recipient area.

Objective:To investigate the application of local free-style perforator flap in repairing gluteal bedsores.Methods:A retrospective study was performed. Date from 35 patients(20 males and 15 females, mean age 46 years old, range from 24-71) with gluteal bedsores between June 2017 and June 2019 were retrieved and reviewed by the Department of Burn and Plastic Surgery, Second Xiangya Hospital of Central South University. Among these cases, 13 were paraplegia after trauma, 6 were paralysis after cerebral hemorrhage, 13 were chronic infection, and 3 were poor wound healing after tumor resection. The average defect size was 5.6 cm×5.0 cm(range from 2.0 cm×3.0 cm to 10.0 cm×5.0 cm). By following the concept of free-style perforator flap, the flap was designed near the wound according to the perforator location detected by Doppler before surgery, and the defects were recovered by the flaps by rotation or other method such as rotation. Or the perforator flap can be modified into dermis-fat flap and flipped 180° to recover the wound. After the surgery, the survival of the flap or the dermis-fat flap, wound healing, as well as the sense and motion function of buttock and lower limbs were observed and recorded.Results:21 cases were repaired by perforator flap and 14 cases were repaired by modified dermis-fat flap. The size of flap range from 3.0 cm×3.0 cm to 10.0 cm×7.0 cm. The follow-up time was 3-22 months(mean, 12 months). All perforator flaps and dermis-fat flaps survived. The appearance of buttock was pleasant and no recurrence of bedsores. The patients without paraplegia had no major sensory loss and pain. The function of gluteus maximus was basically normal, and the motor function of lower limb was also generally satisfactory.Conclusions:The local free-style perforator flap or modified dermis-fat flap has advantages including simple design and operation, reliable blood supply and minimal damage to the donor site. It is a better way to repair gluteal bedsores.

Objective:To evaluate the effect of preoperative 3D simulation on the evaluation of rhinoplasty.Methods:From December 2017 to March 2019, patients in the Department of Burn and Plastic Surgery of the Second Xiangya Hospital of Central South University were randomly selected as the research subjects. According to whether they had received 3D simulation before surgery, they were divided into the experimental group (after 3D simulation before comprehensive surgery) and the control group (without 3D simulation before comprehensive surgery). Visual analogue scale (VAS) and Rhinoplasty Outcomes Evaluation (ROE ) questionnaires were used to evaluate the satisfaction of all patients preoperative and one month after surgery.Results:At the beginning of this study, a total of 97 cases were included, 97 cases were given questionnaires, and 60 cases were effectively recovered, 30 cases in each group.There was statistical significance in the improvement of the postoperative VAS scores between the experimental group and the control group ( P<0. 05). The mean improvement in the experimental group was (4. 10±0. 88) points, while the mean improvement in the control group was (2. 53±0. 73) points. There was statistical significance in the improvement of the postoperativeROE satisfaction scores between the two groups. The average preoperative satisfaction score of the experimental group was (29. 5±9. 7) points, which increased to (77. 3±13. 7) points after surgery. In the control group, the average satisfaction score was (30. 4±11. 3) points before surgery and increased to (62. 7±23. 4) points after surgery. Conclusions:3D simulation before nasal synthesis can improve the postoperative satisfaction of patients.VAS and ROE questionnaires are good tools for evaluating the effect of comprehensive rhinoplastic surgery.
