A case series of early and late cranioplastycomparison of surgical outcomes

BackgroundCranioplasty is an increasingly common procedure performed in neurosurgical centres following a decompressive craniectomy (DC), however, timing of the procedure varies greatly.ObjectivesThe aim of this study is to compare the surgical outcomes of an early compared to a late cranioplasty procedure.MethodsNinety adult patients who underwent a prosthetic cranioplasty between 2014 and 2017 were studied retrospectively. Timing of operation, perioperative complications and length of stay were assessed. Early and late cranioplasties were defined as less or more than 3months since craniectomy respectively.ResultsOf the 90 patients, 73% received a late cranioplasty and 27% received an early cranioplasty. The median interval between craniectomy and cranioplasty was 13months [range 3-84] in late group versus 54days [range 33-90] in early group. Twenty-two patients in the early group (91%) received a cranioplasty during the original admission while undergoing rehabilitation. Complications were seen in 25 patients (28%). These included wound or cranioplasty infection, hydrocephalus, symptomatic pneumocephalus,post-operative haematoma and cosmetic issues. The complication rate was 21% in the early group and 30% in the late group (P value 0.46). There was no significant difference inthe rate of infection or hydrocephalus between the two groups. Length of stay was not significantly increased in patients who received an early cranioplasty during their initial admission (median length of stay 77days versus 63days, P value 0.28).ConclusionWe have demonstrated the potential for early cranioplasty to be a safe and viable option, when compared to delayed cranioplasty.
