Analysis Of Factors Affecting The Results Of Double Eyelid Operation By Incision Method

Objective:This paper was to analysis the factors that affect the operation effect of double eyelid operation by incision method,including HLPF(Horizontal Length of Palpebral Fissure),VHPF(Vertical Height of Palpebral Fissure),the severity of upper eyelid skin flabby,HRES(Height of Removing Eyelid Skin),VROF(Volume of Removing Orbital Fat),the severity of epicanthus,ICD(Inner Canthic Diameter),respectively.By this way,to investigate the law of VHPF,as well as the law of the amount of skin and fat were removed in the patients with different severity of upper eyelid skin flabby.Besides,to investigate SICD(Shorter Inner Canthic Diameter)in epicanthus with different severity,and then to evaluate the result of improved epicanthoplasty by skin resetting.Further more,obtaining SICD and VHPF can provide valuable data and ideas for orthopedists anticipating the effect of the operation and for their clinical work.Methods:103 patients with double eyelid operation by incision method in the department of burn and plastic operation of Guizhou provincial people's hospital from July 2018 to July 2019 were included in this study.Before operation and 180 days after operation,the eye morphology of the patients were measured and evaluated,and HLPF(Horizontal Length of Palpebral Fissure),VHPF,ICD(Inner Canthic Diameter),the severity of epicanthus,the severity of upper eyelid skin flabby were recorded,respectively.During the operation,the height of double eyelid incision,HERS(Height of Removing Eyelid Skin)and VROF(Volume of Removing Orbital Fat)were measured and recorded.To evaluate the effect of the operation.For the patients with different severity of upper eyelid skin flabby,to analyze the age difference of each group,besides to analyze VHPF after operation and both of HERS and VROF in operation.For the patients with different severity of epicanthus,to analyze the age difference of each group,besides to analyze increscent values of HLPF/ICDand SICD after correcting epicanthus.Results: The incision of the operation area of 103 patients healed in the first stage.The age ranged from 18 to 55 years,with a mean age of 28.97±8.07 years,and 56 patients underwented improved epicanthoplasty by skin resetting in the same period.The incision of the double eyelid radian were natural and smooth,besides the shape of the inner canthus were beautiful and without obvious scar.(1)Among the 103 patients,there were statistically significant difference among the patients without upper eyelid skin flabby group and sild to moderate upper eyelid skin flabby groups,respectively(P<0.01).There were no statistically significant difference in age among the patients without upper eyelid skin flabby group,the mild upper eyelid skin flabby group,and the moderate upper eyelid skin flabby group,respectively(P>0.05).(2)Among the 103 patients,the inter-group differences of patients with slihgt to severe upper eyelid skin flabby were statistically significant(P<0.01).There were no inter-group difference between patients without upper eyelid skin flabby group and those with slight upper eyelid skin flabby group(P>0.05).Among the 103 patients,HRES in patients without upper eyelid skin flabby group and patients with slight to severe upper eyelid skin flabby groups were1.64±0.99 mm,3.63±0.43 mm,4.84±0.75 mm,6.55± 0.67 mm,respectively.The inter-group differences were statistically significant(P<0.01).The VROF in patients without upper eyelid skin flabby group and patients with slight to severe upper eyelid skin flabby groups were 0.09±0.08 ml,0.17±0.13 ml,0.27±0.13 ml,0.36± 0.14 ml,respectively.The inter-group differences were statistically significant(P<0.01).(3)Among the 56 patients of correcting epicanthus,the difference values of HLPF/ICD before and after operation in patients with different severity of epicanthus were statistically significant(P<0.01).And HLPF/ICD were more closer to 1 after operation.Among the 56 patients of correcting epicanthus,SICD gradually increased in patients with slight to severe epicanthus groups after operation,which were 2.63±0.97 mm,4.20±0.84 mm,6.08±0.81 mm,respectively.The intergroup differences were statistically significant(P<0.01).Conclusion:(1)The more flabby the skin of upper eyelid were,the more the amount of skin and fat were removed from the upper eyelid,and the more obvious VHPF were increased after double eyelid operation by incision method.
