Background: t.e opt.mal t.me t. closure of a newborn wit. a myelomeningocele has been t.e focus of a number of evaluat.ons. t.e t.ming of primary surgery has received significant.at.ent.on due t. it. relat.onship t. repair-sit. infect.on t.at.can lead t. increased morbidit. and prolonged hospit.l st.ys. It.is on t.is basis t.at.recommendat.ons have ut.lized 48 - 72 hours post.birt. as ideal t.me of closure. t.is is not.only prevent.infect.on at.t.e sit. but.also prevent.vent.iculit.s and neural st.uct.re damage. We t.erefore, hypot.esized an increase in wound infect.on rat.s in t.ose pat.ent. wit. delays in myelomeningocele repair. Met.ods: We ret.ospect.vely reviewed t.e records of 103 children wit. myelomeningocele t.eat.d bet.een 2016 and 2023. At.discharge t.e pat.ent. were followed up at.t.e post.operat.ve clinic visit.2 weeks lat.r. Children were assigned t. 1 of 2 groups, t.ose who underwent.primary neurosurgical repair wit.in 72 hours of delivery (Group 1) and t.ose undergoing repair aft.r 72 hours (Group 2). We compared t.e infect.on rat.s. Result.: 103 children who underwent.myelomeningocele repair were ident.fied, wit. a median t.me from birt. t. t.eat.ent.of 1 day. Eight.(7.8 %) pat.ent. were not.d t. have post.repair surgical sit. complicat.ons. t.ere was no significant.difference in rat.s of infect.on bet.een Group 1 and Group 2 repair t.mes. t.e presence of infect.on was associat.d increased lengt. of st.y when compared t. neonat.s wit.out.infect.on. Conclusion: In children wit. myelomeningocele, t.e t.ming of primary neurosurgical repair appears not.t. have a significant.impact.on surgical sit. infect.on. Closure of t.e spinal lesion wit.in t.e first.72 hours of life may be more favorable for neural damage prevent.on. t.ese result. suggest.t.at.early myelomeningocele repair may not.impart.significant.y on t.e rat. of wound-sit. infect.on.
