ABSTRACT
Objective:To compare the clinical efficacy of autologous fat injection and conjunctival pedicled orbital septal fat grafting for infraorbital margin depression in young people.Methods:Fourty young patients with lower eyelid pouch and infraorbital margin depression with age of 20 to 40 years and average age of 30.6 yaers in the First Affiliated Hospital of Nanchang University from September 2017 to September 2019 were enrolled. According to the surgical method, all patients were divided into 2 groups with 20 cases each. Group 1 underwent transconjunctival orbital septum fat reset. Group 2 underwent various autologous fat injection after proper amount of orbital septal fat being removed, including structural fat, fine-particle fat and nano-fat, performed in different parts and layers. The tear trough rating scale (TTRS) scores and patients＇ satisfaction at 1 year after operation between 2 groups were compared.Results:Compared with the preoperative TTRS scores, the differences in scores at 6 months and 1 year after surgery were statistically significant ( P<0.01). The scores between two groups were compared at 6 months and 1 year respectively after the operation, and the difference were both statistically significant ( P<0.01). 6 months after the operation, the TTRS scores including four items were carefully compared between the two groups. It showed that the reduction of tear groove depth ( P<0.05), pigmentation ( P<0.01) and wrinkle ( P<0.01) in group 2 were more obvious than those in group 1. The percentage of satisfaction in group 2 (95%) was higher than that in the group 1 (70%), and the difference was statistically significant ( P<0.01). Conclusions:For infraorbital margin depression of young people, after proper amount of orbital septal fat being removed, various free fats graft injection into different parts and layers could obtain better treatment results, reducing not only the depth of the tear groove, but also periorbital pigmentation and fine wrinkles.
ABSTRACT
Objective@#To discuss a method, increasing the resistance and decreasing the power of the levator palpebrae superioris, to treat the upper eyelid retraction, after upper blepharoplasty, and summarize the feasibility and efficacy of this operation.@*Methods@#A total of 33 female patients (42 eyes) with upper eyelid retraction after blepharoplasty were treated. According to preoperative evaluation, an adjusted method, levator tendon membrane and Muller′s muscle compound tissue turnover flap, was selected. Following the incision of past blepharoplasty, scar and adhesions were removed as much as possible. The space between orbital septum and levator palpebral tendon membrane was widely separated, as well as the space between levator palpebral tendon membrane and Muller′s muscle, and the conjunctiva. A composite tissue flap consisting of levator palpebral tendon membrane and Muller′s muscle was formed. At the spot above the end of the composite tissue flap, paralleling to the upper edge of upper tarsal plate, the tissue was stripped. The compound flap was divided into two layers, a deep and a shallow layer, to form the aponeurosis turnover flap with pedicle at the free end. The turnover flap was horizontally sutured to the upper edge of tarsal plate. The buccal fat pad was cut and covered, between the levator palpebral tendon membrane and the orbital septum fat. At the end, conventional blepharoplasty was performed to close the incision.@*Results@#All the incisions were primary healed. Stitches were taken out 7 days after surgery. There was different scar proliferation. The recovery period last 3-6 months. Transplanted buccal fat was survived, without nodule, liquefaction, unevenness or other complications. All patients were followed for 3 to 12 months, with a mean follow-up of 6 months, for static and dynamic assessment. In static evaluation, the upper palpebral margin decreased by 2 mm. The upper palpebral margin decreased by 3 mm on average. Three cases (9%) had insufficiently corrected upper eyelid retraction, 2 cases (6%) recurred upper eyelid retraction in 3 months after operation, while the other 28 cases (85%) showed satisfactory results.@*Conclusions@#The upper eyelid tendon membrane and Muller′s muscle compound tissue turnover flap extension is helpful to correct the upper eyelid retraction, caused by blepharoplasty.

ABSTRACT
Objective@#To investigate the clinical efficacy of combined nano-fat and structural fat transplantation for periocular rejuvenation, such as fine wrinkle, darkness and volume loss.@*Methods@#Structural fat was harvested by Coleman′s structural fat grafting technique from thigh and was grafted at different layers for depression correction. Nano-fat was harvested by Tonnard′s nano-fat technology from thigh and was injected smoothly intradermally and subcutaneously for correction of fine wrinkle and darkness.@*Results@#The patients were followed up for 3—12 months, 6 months in average. Satisfactory result was achieved in 42 cases after only one operation. No complication happened. 2 cases was unsatisfied due to upper eyelid fullness. 4 cases didn′t get improvement in periocular darkness.@*Conclusions@#Combined nano-fat and structural fat transplantation are effective for periocular rejuvenation, including depression deformity and skin darkness.
ABSTRACT
Objective@#To investigate the feasibility and efficiency of refined Converse otoplasty with Ω shape for correcting prominent ears.@*Methods@#Refined Converse otoplasty with Ω shape was performed in 8 cases(3 cases of bilateral deformities)of prominent ears during January 2014 to September 2016. The postauricular fascial-perichondrial complex tissues were elevated through postauricular incision based on Converse otoplasty. The new antihelix was reformed by parallel mattress sutures though postauricular parallel cartilaginous incisions. The Ω shape appeared on the transverse section of the auricular cartilage after fascial-perichondrial sutures.@*Results@#Postoperative 6 month to one year follow-up presented satisfactory results in all 8 cases. The appropriate location and contour of the recreated antihelix was achieved. The included angle between fossae helicis and concha was decreased. The auricles were symmetric in both unilateral and bilateral patients of prominent ears. The scars were inconspicuous. Hematoma, infection, suture extrusion and secondary deformities were not seen in our series.@*Conclusions@#Natural and clear contour of the recreated antihelix was achieved by refined Converse otoplasty with Ω shape. Reoccurrence was not seen and complications were rare.

<p><b>OBJECTIVE</b>To investigate the effect of topical application of leptin in promoting burn wound healing in rats.</p><p><b>METHODS</b>Four parallel second-degree burn wounds induced on the back of 18 Wistar rats were divided into leptin treatment group (treated with topical application of 400 ng/ml leptin dissolved in PBS) and control group (treated with PBS). The time of wound healing was recorded, and the wound area that was not healed was measured at 3, 7, 11, 15, and 19 days after burns. The tissue at the peripheries of the wound was sampled at 7, 14 and 21 days after burns for pathological examination with HE staining and immunohistochemistry for proliferating cell nuclear antigen (PCNA) to evaluate the proliferation of keratinocytes.</p><p><b>RESULTS</b>Compared with the control group, leptin-treated wounds showed a shorter time (by 2-3 days) of wound healing, and significant differences were found between the two groups in healing at 7, 11, 15, and 19 days after burns. HE staining and immunohistochemistry revealed a faster rate of epidermis growth and a greater thickness of the cuticular layer in leptin-treated wounds at 7, 14 and 21 days after burns. PCNA positivity in the keratinocytes was stronger in leptin-treated wounds than in the control wounds at 7 and 14 days, but no such distinct difference was noted at 21 days between the two groups.</p><p><b>CONCLUSION</b>Topical application of leptin can promote re-epithelization in burn wounds to shorten the wound healing time of burns.</p>
