Comparison of clinical effects between the outside and under temporal muscle method in frontal-temporal cranioplasty by digital forming titanium mesh

Abstract

Objective To compare the clinical effects of the outside and under temporal muscle titanium cranioplasty in mass frontal-temporal skull defect.Methods Clinical data of forty-two frontal-temporal skull defect pa tients who had cranioplasty with digital forming titanium nets were analyzed retrospectively.Two groups were divided according to the surgical method.Twenty-two cases underwent outside temporal and twenty cases under went temporal muscle titanium mesh.Compared with two groups of surgery condition( operation time,blood loss,titanium nail dos age) and postoperative complications( wound infection,subcutaneous effusion,epilepsy,intracranial hematoma,chew limited,facial paralysis) and the satisfaction rate of appearance discharged after one month.Results The operation time of outside temporal muscle group was obviously less than under temporal muscle group( t =2.42,P ＜ 0.05 ),but the under temporal muscle group patients were more satisfied with the postoperative appearance ( x2 =36.31,P ＜0.05 ).There was no obvious difference of the postoperative complication between the two groups ( x2 =1.80,P ＞0.05 ).Conclusion Both the outside and under temporal muscle method had its advantages and disadvantages.Operation methods selection should comprehensively and individually according to the specific condition of patients,surgi cal doctor's clinical experience.
