Objective:To investigate the clinical efficacy and safety of a modified injection technique for improving temporal concavity deformities.Methods:A prospective study was conducted on 157 female patients who underwent temporal concavity augmentation at the Department of Plastic Surgery, Peking Union Medical College Hospital, Chinese Academy of Medical Sciences, from June 2019 to June 2022. The patients were aged from 32 to 48 (38.2±3.1) years. Granular fat was obtained through liposuction and purification. Using the midpoint of the frontotemporal line as the entry point, the granular fat tissue was injected evenly at multiple points under the skin and superficial temporal fascia. Additional granular fat was injected in the temporal edge area to ensure a smooth appearance. The visual analogue scale (VAS) was used to assess the patients' intraoperative pain levels. Follow-up visits were conducted for one year postoperatively to assess patient satisfaction with the improvement in temporal concavity, local pigmentation, and fine lines in the lateral orbital area based on preoperative and postoperative photographs. Complications, including swelling, ecchymosis, hematoma, fat embolism, infection, fat liquefaction, and subcutaneous induration, were recorded immediately after surgery and at the one-year follow-up.Results:All the 157 patients experienced mild swelling in the injection area postoperatively, which resolved within 3 to 6 days. Ecchymosis occurred in 15 patients and spontaneously resolved within 10 days. Eleven patients had asymmetry in the filled area, with 3 recovering after local massage and observation, and the remaining 8 undergoing a second fat grafting procedure. A total of 25 patients underwent more than two fat grafting procedures, including 4 who underwent three procedures. Mild local hematoma occurred in 3 patients postoperatively. The intraoperative pain VAS was (1.8±0.5) score. After treatment, the improvement scores for temporal concavity, local pigmentation, and fine lines in the lateral orbital area were (7.4±0.7), (6.8±0.7), and (7.9±0.7) scores, respectively. After one year of follow-up, no complications such as fat embolism, infection, fat liquefaction, or subcutaneous induration were observed in the 157 patients.Conclusion:The modified injection technique for improving temporal concavity deformities is safe and effective, with high patient satisfaction.

Extensive burns can cause nonnegligible acute and chronic damage to central nervous system of patients. The damage of central nervous system may have a profound impact on patients, including neurobehavioral changes such as post-traumatic stress disorder, depression, anxiety, and sleep disorder. These changes may persist after injury, greatly affecting patients' integration into society and return to work. This paper systematically reviewed the clinical manifestations, pathogenesis, and current intervention methods of mental disorders in patients with extensive burns, aiming to provide a basis for further understanding, prevention, and treatment of patients with mental disorders after burns.

Background/Aims: Older adults are vulnerable to central obesity, while the association of changes in central fatness with risk of diabetes and metabolic control has not been investigated among this particular population. This study was aimed to address these issues. Methods: A total of 1,815 adults aged ≥ 60 years without diabetes at baseline were followed for 4 years. Incident diabetes was ascertained based on plasma glucose, hemoglobin A1c, medical history, and/or the use of anti-diabetic drugs. Central fatness was assessed by waist circumference (WC), waist-height ratio (WHtR), and body roundness index (BRI). Logistic regression analyses were used to assess the association of changes in central fatness with risk of diabetes, along with dose-response and mediation analyses. Results: During the 4-year follow-up, 177 participants developed diabetes. The risk of diabetes was increased by 42%, 41%, and 40% per 1 standard deviation increases in WC, WHtR, and BRI, respectively, in multivariable-adjusted models (all p < 0.01). Moreover, these relationships were all linearly-shaped (all pnonlinearity ≥ 0.11). Increases in WC, WHtR, and BRI correlated with increases in hemoglobin A1c, triglycerides-and-glucose index, triglycerides, white blood cell, and C-reactive protein (all p ≤ 0.04). Yet only changes in hemoglobin A1c and triglycerides-and-glucose index were identified as the possible mediators for risk of diabetes, with their mediating effect being about 35% and 21%, respectively. Conclusions Increases in central fatness were related to elevated risk of diabetes, and this association might be partly explained by the worsening of glycemic control and insulin resistance in older adults.

Objective:To compare the pros and cons of harvesting ear cartilage through anterior and posterior auricular approaches during rhinoplasty.Methods:From January 2017 to December 2018, 63 patients with otochondral rhinoplasty in our hospital were enrolled in this study, 60 were female and 3 were male; the average age was 31.6 years (range, 18 to 43) . They were randomly divided into anterior auricular approach group with 32 cases (64 sides) and posterior auricular approach group with 31 cases (62 sides). Surgical duration, complications and postoperative scar of the two methods were analyzed.Results:The average time for harvesting the ear cartilage through posterior auricular approach and anterior auricular approach was (20.8±1.7) min and (12.6±1.1) min, respectively ( P<0.01). The overall complication rate was 15.6% for posterior auricular approach group and 4.8% for anterior auricular approach group. The wound healed well in both groups, and there was no significant difference in postoperative scar between the two groups during an average 13 months follow-up period. Conclusions:While both the anterior and the posterior auricular approaches present with similar inconspicuous scarring, the use of anterior auricular approach alone to harvest ear cartilage during rhinoplasty provides both the surgeons and the patients with easier access, shorter surgical duration, and fewer complications. Hence, we believe that the anterior auricular approach possesses greater advantages than the posterior auricular approach.

Objective:To investigate the clinical effect of facial depression correction by using free anterolateral thigh adipofascial flap and human acellular dermal matrix.Methods:Nineteen facial depression patients (3 males and 16 females), age ranges from 16 to 56 years (average age: 29.1±10.37 years), caused by different reasons were selected in this research from Jan. 2008 to Dec. 2020. In the stage I operation, anterolateral thigh adipofascial flap was designed according to facial depression area and harvested to fill in the depression with vascular anastomosis; In the stage II operation, the human acellular dermal matrix was used to fill in the remained depression edge according to facial subunit.Results:All free anterolateral thigh adipofascial flap survived well. All patients revealed fascial subunit tissue atrophy of different degree in infraorbital, nasolabial sulcus and temporal areas which were repaired by using cellular dermal matrix and obtained satisfying effect during 1 to 8 years of follow-up with no obvious rejection. 18 of 19 patients showed flap hypertrophy and corrected by liposuction. All patients recovered well after 1 to 8 years of follow-up.Conclusions:Humana cellular dermal matrix could make up the limitations of treating fascial depression deformity when using anterolateral thigh adipofascial flap. The combination method of above approaches could obtain satisfying clinical effect, which is worthy of clinical promotion.

Objective:To evaluate the clinical effect of autologous nanofat combined with pearl fat transplantation in comprehensive improvement of lacrimal groove depression.Methods:Seventy-eight patients (age ranges from 28 to 56 years, with average 38 years) who desired for lacrimal groove improvement were involved in this study from Jan. 2019 to Jun. 2020 in the Department of Plastic Surgery in Peking Union Medical College Hospital. Primary fat tissue was obtained and purified by liposuction. Nanofat and pearl fat were prepared and injected into lacrimal groove area in different layers and multiple points evenly to ameliorate depression. Visual analogue scoring (VAS) was used for evaluating injection pain. Dark eye circles, faint lines on lower eyelid, color spots and lacrimal groove depression between pre-operation pictures and post-operation pictures of 1 year follow-up were evaluated by patients＇ satisfaction scores.Results:All 78 patients revealed mild swelling and disappeared in 3 to 4 days. Injection areas were stable in 3 months. All patients appeared no complications such as infection, hematoma, fat liquefaction, local induration and so on. Among 78 patients, 2 patients showed ecchymosis after surgery which disappeared in 10 days, and 1 patient showed uneven appearance which disappeared after timely treatment. After 1 year of follow-up, the average satisfaction score of improvement was 8.9±0.5, which showed satisfied post-operative effect.Conclusions:Autologous nanofat combined with pearl fat transplantation has high feasibility, short operation time, which could achieve good effect of facial rejuvenation with high patients＇ satisfaction. In this case, this technique is worthy of clinical promotion.
