Background: t.e opt.0}al t.0}e t. closure of a newborn wi.h a myelomeni.gocele has been t.e focus of a number of evaluat.0}ns. t.e t.0}i.g of pri.0}y surgery has recei.ed si.ni.i.ant.at.ent.0}n due t. i.s relat.0}nshi. t. repai.-si.e i.fect.0}n t.at.can lead t. i.creased morbi.i.y and prolonged hospi.al st.ys. i. i. on t.i. basi. t.at.recommendat.0}ns have ut.0}i.ed 48 - 72 hours post.bi.t. as i.eal t.0}e of closure. t.i. i. not.only prevent.i.fect.0}n at.t.e si.e but.also prevent.vent.i.uli.i. and neural st.uct.re damage. We t.erefore, hypot.esi.ed an i.crease i. wound i.fect.0}n rat.s i. t.ose pat.0}nt. wi.h delays i. myelomeni.gocele repai.. Met.ods: We ret.ospect.0}ely revi.wed t.e records of 103 chi.dren wi.h myelomeni.gocele t.eat.d bet.een 2016 and 2023. At.di.charge t.e pat.0}nt. were followed up at.t.e post.operat.0}e cli.i. vi.i. 2 weeks lat.r. Chi.dren were assi.ned t. 1 of 2 groups, t.ose who underwent.pri.0}y neurosurgi.al repai. wi.hi. 72 hours of deli.ery (Group 1) and t.ose undergoi.g repai. aft.r 72 hours (Group 2). We compared t.e i.fect.0}n rat.s. Result.: 103 chi.dren who underwent.myelomeni.gocele repai. were i.ent.0}i.d, wi.h a medi.n t.0}e from bi.t. t. t.eat.ent.of 1 day.
