Abstract
ObjectiveOne of the common complications occurring after cranioplasty (CP) is aseptic bone-flap resorption (ABFR). Reoperation necessary because of the development of ABFR can lead to unfavorable complications during subsequent surgery using a synthetic skull implant, and also necessarily leads to higher costs. The aim of this study is to identify prognostic factors that may help to predict the development of ABFR.MethodsIn this study, 303 CP surgeries performed between 2002 and 2017 were examined retrospectively to identify factors predicting the occurrence of ABFR. A number of these factors (e.g., time lapse between decompressive craniectomy (DC) and CP, bone-flap size, specific laboratory signs, and the reason for the original DC) were analyzed as possibly influencing the risk of developing ABFR.ResultsABFR of an autologous bone flap that subsequently required a CP with synthetic skull implants occurred in 10 of 303 patients (3.0%). CP timing and patients' Karnofsky Performance Scores (KPS) (p = 0.008; p = 0.012) were identified as significant factors with an impact on the development of ABRF. Age did not reveal a significant value, but statistical analysis shows a clear trend. The younger the age, the more likely it was that an ABFR would develop.ConclusionThe risk of ABFR lessens the longer the period of time elapsed between DC and CP. Age does not reveal a significant value, but statistical analysis shows that there is a clear trend.
Highlights
Decompressive craniectomy (DC) is performed to reduce refractory increased intracranial pressure e.g., pressure due to intracerebral hemorrhage, traumatic brain injury, or ischemic stroke[1,2,3]
The younger the age, the more likely it was that an Aseptic bone-flap resorption (ABFR) would develop
Autologous bone flap harvested at the time of a DC, as well as synthetic materials including porous polyethylene, methyl methacrylate, titanium, hydroxyapatite, ceramics, and osteoconductive bioresorbable materials, are frequently used to perform CP [11,12,13,14,15]
Summary
One of the common complications occurring after cranioplasty (CP) is aseptic bone-flap resorption (ABFR). Reoperation necessary because of the development of ABFR can lead to unfavorable complications during subsequent surgery using a synthetic skull implant, and necessarily leads to higher costs.
