Objective:To investigate the feasibility of a new clinical grading scale for assessing the degree of laxity of upper eyelid skin.Methods:From May 2022 to October 2023, the patients who underwent upper eyelid skin laxity plastic surgery in the Department of Plastic Surgery and Burns-Department of Medical Cosmetology, Northern Jiangsu People’s Hospital Affiliated to Yangzhou University, were prospectively enrolled. The degree of upper eyelid skin laxity was graded independently by three plastic surgeons who did not participate in the operation according to the grading scale and using facial photographs of the patients.The clinical grading scale categorizes the degree of skin laxity into 4 grades ranging from 0 to 3 degrees, by analyzing the position of the lower edge of the upper eyelid skin relative to the upper eyelid edge and the pupil, and the higher the grade, the more serious the degree of skin relaxation. If bilateral upper eyelid skin laxity were presented, the grade of the side with more severe laxity was taken as the grade of the upper eyelid skin laxity of the patient. The Kendall coefficient (range -1-1) of the three doctors’ grading result before and after operation was calculated respectively. The closer the value was to 1, the better the consistency of the three doctors, and the better the stability of the grading scale. The degree of upper eyelid skin laxity before and after operation was expressed as M ( Q1, Q3), and the paired Wilcoxon signed rank test was used for comparison. Results:A total of 50 female patients aged 32 to 67 years old (mean 45.3 years) who underwent bilateral upper eyelid skin laxity plastic surgery were enrolled. The Kendall coefficients of the grading result of the upper eyelid skin laxity of 50 patients by three doctors before and after operation were 0.975 and 0.882, respectively ( P<0.01). It suggested high consistency among evaluators for the same patient. 50 patients were graded as 2(1, 2) degree and 0(0, 0) degree preoperatively and postoperatively, respectively, indicating that the degree of upper eyelid skin laxity was significantly improved postoperatively. The result of Wilcoxon signed rank test showed that there were significant differences in preoperative and postoperative grading result of the three doctors ( P<0.01). Conclusion:The grading scale of upper eyelid skin laxity is objective and easy to use. Its evaluation result are stable and repeatable, and it can effectively analyze the changes of the degree of upper eyelid skin relaxation before and after surgery.

Objective:To investigate the cosmetic effect of biplane fixed technique for double-eyelid plasty.Methods:From September 2019 to June 2021, 80 patients, including 6 males and 74 females, aged 18-45 years with an average age of 31 years, were treated with single eyelid cosmetic surgery at the Medical Aesthetics Department of Northern Jiangsu People′s Hospital Affiliated to Yangzhou University. All the cases were performed by the " biplane fixed technique", and the key point of the surgery was to fix the orbicularis labii muscle in biplane (hard fixation plus soft suspension). A questionnaire survey was conducted and preoperative and postoperative photos were collected for statistical analysis to evaluate postoperative outcomes. The patients were follow up for 6-12 months after surgery, and the incidence of postoperative complications were calculated.Results:The incisions of 80 patients all healed by first intention. 79 patients were satisfied, accounting for 98.75%. Physicians evaluated 78 cases as satisfactory, accounting for 97.50%. The Vancouver Scar Scale score was 2.31±1.80, and the Edema and Eczema Visual Simulation Scale score was 3.58±2.15. After surgery, there were no significant abnormalities when eyes opening or closing, and the shape of the double eyelid remained intact without shedding. The scar on the closed eye incision was mild and there was no obvious depression.Conclusions:The " biplane fixed technique" blepharoplasty can form a firm double eyelid line, which is not easy to fall off and has slight scars. The postoperative effect is stable and worthy of clinical application.

Objective:To investigate the clinical effect of the subbrow blepharoplasty by fixing and folding inward the orbicularis oculi muscle in a single point to improve the upper eyelid skin laxity.Methods:From May 2016 to February 2019, 109 patients (16 males and 93 females)underwent subbrow blepharoplasty combined with single point orbicularis oculi muscle fixing and folding (SBB-soff)in the Outpatient Department of Plastic Surgery Northern Jiangsu People’s Hospital. During the operation, the spindle skin below the eyebrow was excised, and the orbicularis oculi muscle (OOM) was retained. Then we made a small incision at the supraorbital rim, deep down to the periosteum. The OOM was folded inward and fixed on the periosteum in a single point through this small incision. The effect of the operation was evaluated by a questionnaire survey and statistical analysis of preoperative and postoperative photographs.The height margins of the upper eyelids and eyebrow position were evaluated by a questionnaire survey and statistical analysis of preoperative and postoperative photographs (use the iris diameter as one unit). Repeated measures t test was used for analyzing normal distribution data, the non-parametric Wilcoxon test was used for statistical analysis of abnormal distribution data, and P<0.05 was considered to be statistically significant. Results:The incisions of all the 109 cases had primary healing. The postoperative follow-up period averaged a period of (9.57±6.13)months (3 months to 3 years). 85.3% of patients (93 of 109) were followed up for more than 6 months. The subjective questionnaire survey showed that patients’ satisfaction rate was 99.1% (108 of 109) at one month postoperatively, and there were no serious postoperative complications in the sensory function of the forehead, the motor function of eyebrows and upper eyelids, etc.The upper eyelid margins at the sites above the mid pupil points elevated from (0.466±0.149) units to(0.600±0.126) units ( t=-16.186, P<0.001). The upper eyelid margins at the sites above the lateral limbus elevated from(0.387±0.156)units to (0.568±0.166) units ( t=-31.882, P<0.001). The upper eyelid margins at the sites above the lateral canthus elevated from (0.214±0.087) units to (0.446±0.098) units ( t=-49.332, P<0.001). In addition, all the differences were statistically significant.A total of 86 patients were followed up for 6 months without intraoperative eyebrow position adjustment. The data from each measuring point of the statistical baseline to the inferior edge of the eyebrow showed that the eyebrow height at 6 months postoperatively descended slightly, but the difference was not statistically significant ( P>0.05). The periodic appearance and function were significantly improved after the operation. Conclusions:SBB-soff can improve the dermatochalasis and aging signs of the upper eyelid tissue and make no negative effects on the position of eyebrows. In addition, it has the advantages of uncomplicated operation, less trauma, and persistent effect.
