Clinical Efficacy Analysis Of Modified Transsection And Longitudinal Suture In Epicanthoplasty

ObjectiveTo introduce a modified transsection and longitudinal suture in epicanthoplasty,summarize its clinical effectiveness through measuring contour data of orbital eyes and the changes of relative ratio relaitionship during pre-operation and postoperation.Methods52 cases(50 females,2 males)of epicanthus patients which were successfully obtained data follow-up over 6 months and treated by the department of plasty,the 1st Hospital of Nanchang University from June 2016 to October 2017.Patients of this group were underwent epicanthoplasty with modified transsection and longitudinal suture,part of them were treated by blepharoplasty at the same time.The Horizontal Lid Fissure Length(HLFL),Intercanthal Distance(ICD),Medial epicanthal distance(MED)and the scar in operation area were measured preoperatively and postoperatively,with the calculated ratio of Horizontal Lid Fissure Length to Medial epicanthal distance(HLFL/MED).The improvement of each date and the ratio were preoperatively and postoperatively analyzed by the statistical software IBM SPSS statics 23 to evaluate the corrective effection of this aforementioned method.ResultAll the incisions healed by first intention,no lacrimal canaliculi injury occurred in the patients.The average follow-up time is from 6 months to 21 months(mean,9.3 months).The medial epicanthal distance decreased from(37.94±3.19)mm pre-operation to(32.27±2.42)mm at immediate time after the post-operation,a trend of minor retraction in 6 months after the operation at(34.49±2.46)mm.The intercanthal distance decreased from(34.24±2.61)mm pre-operation to(32.27±2.42)mm at immediate time after the post-operation and also a minor retraction in 6 months after the operation at(33.28±2.57)mm.The horizontal lid fissure length increased from(27.01±1.09)mm pre-operation to(3.01±1.48)mm at immediate time after the post-operation,and then in 6 months that after the operation at(28.74±1.06)mm.The ratio of horizontal hid fissure length to medial epicanthal distance in pre-operation is(0.717±0.063),a minor augment at(0.936±0.067)in immediate time after the post-operation and(0.837±0.056)in 6 months.The improvement of the medial epicanthal distance,compared with the pre-operation,has been reduced(3.45±1.19)mm after 6 months post-operation(paired t test,P<0.05),while a trend of minor retraction was noticed at immediate time after the post-operation at(2.21±0.92)mm(paired t test,P<0.05).The shorten distance of the Intercanthal Distance,compared with the pre-operation,has been reduced(0.95±0.59)mm after 6 months post-operation(paired t test,P<0.05),while a trend of minor retraction at immediate time after the post-operation at(1.01±0.87)mm(paired t test,P<0.05)as well.The augment of the horizontal lid fissure length,compared with the pre-operation,has been increased(1.72±0.55)mm after 6 months post-operation(paired t test,P<0.05),while a trend of minor decreased than immediate time after the post-operation at(1.34±0.67)mm(paired t test,P<0.05).The improvement of the ratio of horizontal lid fissure length to intercanthal distance,compared with the pre-operation,was(0.120±0.027)after 6 months post-operation(paired t test,P<0.05),while a trend of minor decreased than immediate time after the post-operation at(0.099±0.037)(paired t test,P<0.05).Patient and observer scar assessment scale scores: patient scar assessment scale scores are 10.20±0.82,observer scar assessment scale scores are 7.10±0.70,patient overall satisfaction score scores are 2.10±0.20,observer overall satisfaction score scores are 2.60±0.32.ConclusionsThe modified transsection and longitudinal suture in epicanthoplasty has the advantages of simple design,easy operation,Small trauma,inconspicuous scar,obviousand stable postoperative effectiveness.
