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.

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 introduce a surgical technique applied in autologous costal cartilage rhinoplasty described as the endonasal incision combined with umbrella-like graft.Methods:From February 2018 to May 2019, a total of 52 patients (48 females and 4 males) were enrolled and underwent rhinoplasty operation with bilateral intranasal incision for the construction of umbrellal scaffolds in Department of Burn and Plastic Surgery of the Second Xiangya Hospital. During the operation, bilateral inferior lateral cartilages were fully separated and septal cartilages were exposed. Umbrellal-like scaffolds were built to correct nasal aesthetic defects such as nasal columellar shrinkage and insufficient nasal tip protrusion. During the process of follow-up, all the patients were photographed and were asked to complete the the postoperative satisfaction survey by means of an online link or over the phone.Results:The preoperative nasal aesthetic defection was greatly improved. There is no the temporary complications including infection and bleeding. 30 patients who completed follow-up for 6 months at least and completed postoperative satisfaction survey were included in the case series. The measurements (average): The nasofrontal angle was measured as 141.29°±5.61°preoperation and 137.67°±5.27°postoperation. The nasolabial angle was measured as 89.53°±10.56°preoperation and 94.90°±5.88°postoperation , The nasal tip angle was measured as 86.60°±7.09°preoperation and 80.42°±5.47° postoperation, Columellar-lobular angle was measured as 48.82°±7.32°preoperation and 44.63°±2.51°postoperation , The tip projection-nasal length index was measured as 0.48±0.07 preoperation and 0.54±0.07 postoperation. Columellar-lobular length index was measured as 1.74±0.36 preoperation and 1.22±0.21 postoperation, There were significantly statistical differences between preoperative and postoperative measures. The photograph showed the location and reflection of nasal tip have remained stable, no upward or twist trend occurred. According to questionaire results, postsurgical swelling relieved in all cases within the first 3 to 6 weeks. No prolonged functional sequelae occured, Most of patients were satisfied with the aesthetic and functional results.Conclusions:Endonasal incision combined with umbrella-shape graft facilitates the operation, Bilateral endonasal incision allowed us to evaluate the reestablished nasal tip directly and adjust tip projection with convenience, there’s no columella scar left.

Objective:To understand sexual needs and factors of risky sexual behaviors among elderly men at different ages in two communities of Qiandongnan Miao and Dong autonomous prefecture and provide basis for targeted HIV prevention and intervention.Methods:Two communities in the prefecture were selected as study sites. Questionnaire surveys were carried out among elderly men aged 50 and over who visited or consulted in the communities from June to December 2018, and they were tested for HIV and syphilis antibodies.Results:Among 400 elderly men, 209 (52.2%) were 50-64 years old, and 191(47.8%) were above 65 years old. They were mainly Miao people, accounting for 66.3% (265/400), and 235 (58.8%) had an education no more than 6 years. HIV awareness of the two age groups were only 25.8% (54/199) and 26.2% (50/191), respectively. Among those aged 50-64, 142 (68.0%) felt normal sexual desire, and 153 (73.6%) reported penile erections or erections in most cases whenever sex, and 52.9% (110) ejaculated most of the time. HIV prevalence was 1.0% (4/400). Compared with the over 65-year-old group, the proportion of having sex with spouse/stable partners (89.5%, 179/200), proportion of no condom use with their spouse/stable sexual partners during the most recent sex (93.8%, 168/179), proportion of having casual sex (11.0%, 23/209) and commercial sex (3.8%, 8/209) were all higher among 50-64 age group. In comparison to those aged over 65 years old, average monthly income>3 000, and use of sex helper, aged 50-64 ( OR=2.70, 95% CI: 1.22-5.95), average monthly income ≤1 000 yuan ( OR=2.79, 95% CI: 1.25-6.21), and no use of sex helper ( OR=3.78) (95% CI: 1.65-8.67) were related factors of HIV risky sexual behavior last time. Conclusion:Elderly men in the minority prefecture had low HIV awareness. Compared with those≥65 years old, the 50-64 age group had more active sexual behaviors and higher sexual needs. Those from 50-64 age group, with lower economic level and good sexual ability were more likely to have HIV risky sexual behaviors.
