Clinical Effect Analysis Of Lower Eyelid Blepharoplasty With Orbital Septal Fat Restitution

Objective: The purpose of this study is to introduce and evaluate an operation that can make the eye circumference younger by returning and fixing the orbital fat herniated from the lower eyelid,attempt to provide a new surgical method for eye rejuvenation.Methods: Collect the preoperative and postoperative data and photos of 150 patients who underwent lower eyelid blepharoplasty with orbital septal fat restitution from January 2021 to October 2022,and analyze the clinical efficacy of the surgery through two-dimensional photo measurement.All the included cases were in good general condition,without infection,coagulation disorders and other major systemic organ diseases,no lower eyelid congenital absence,dysplasia or deformity,no relevant history of surgery,injection filling,tumor history,hyperthyroidism exophthalmos and other endocrine diseases,and all the operators were operated by Professor Hu Gang.Each photo is taken using a unified standard: the patient is in a standing position,with their heels and back tightly against the vertical wall.At a distance of 1 meter from the camera,the patient is instructed to look straight ahead,facing the patient’s face,and the camera center point is aligned with the center of the patient’s face.Take the "iris diameter ruler measurement" as the measuring scale(think of the iris as a circle,divide the diameter of the iris into 20 equal parts,and measure the length of each part in 1 unit of iris diameter),take the horizontal line of the intersection of the upper and lower eyelid margins on both sides at the nasal side as the measuring baseline.Adobe Photoshop 2022 software was used to process the photo data of each case,and IBM SPSS Statistics 27 was used for statistical analysis.First,K-S test was used to verify the normality of all measurement data.The measurement indicators that conform to the normal distribution were expressed in the form of mean ± standard deviation(x ±s),and paired t-test was used for statistical processing;The measurement indexes that do not conform to the normal distribution are represented by the quartile M(P25-P75),and are treated by Wilcoxon’s signed rank test.If P<0.05,the difference is statistically significant.Compare the changes in preoperative and postoperative pupil height(vertical distance from pupil midpoint to baseline),appearance outer canthus height(vertical distance from appearance outer canthus to baseline),eyelid buccal junction sag(vertical distance from eyelid buccal junction to baseline),eyebrow eye distance(distance from pupil midpoint to eyebrow upper edge vertical baseline),and eye fissure height(maximum distance between upper and lower eyelid edges).All values were measured 3 times in the left eye and 3 times in the right eye,Take the mean as the final measurement value.Evaluate the clinical effect of fat reduction and eye bag removal surgery.Results: The measurement results are expressed in units of the iris diameter ruler measurement.The pupillary height was(7.80±1.99)units before operation and(9.38±2.31)units after operation,the difference was statistically significant;The height of the outer canthus was(1.16±5.48)units before operation and(1.54±5.01)units after operation,the difference was not statistically significant;The blepharo-buccal junction sag was 33.08(29.51-35.91)units before operation and 14.49(11.57-17.86)units after operation,the difference was statistically significant;The distance between eyebrows and eyes was(43.75 ± 3.90)units before operation and(42.59 ± 5.06)units after operation,the difference was not statistically significant;The height of eye fissure was(14.80 ± 2.08)units before operation and(15.26 ± 2.25)units after operation,the difference was not statistically significant.2.Summarize the existing research results of the research group on eye circumference and facial rejuvenation.Facial soft and bone tissues undergo varying degrees of changes with age.Introduce minimally invasive adjustable facial lift surgery,and lower eyelid blepharoplasty with orbital septal fat restitution,and autologous fat transplantation with platelet rich plasma.Conclusion: Lower eyelid blepharoplasty with orbital septal fat restitution can raise the height of the eyeball and reduce the distance between the eyelid and cheek junction and the lower eyelid margin.
