Decompressive craniotomy is a commonly performed surgery to relieve raised intracranial pressure. At the end of the procedure, it is the convention to cover the exposed brain by performing a lax duraplasty which allows for both brain expansion and provides protection to the underlying parenchyma. Various commercially available dural substitutes are used for this purpose. These have the drawback of being both expensive and nonvascularized. We propose a technique of using pericranium along with everted temporalis fascia (both being locally harvested vascularized pedicle flaps) that can suffice in a vast majority of cases for covering the brain.

Background: Common complications following cranioplasty (CP) include infections, seizures, bone flap resorption, and intra-cranial hemorrhages. Epidural fluid collections (EFCs), often seen in the immediate post-operative scan as hypo-dense accumulations below the bone flap, have been very infrequently discussed in the literature as in the majority of the cases, they are small, get resorbed spontaneously, and usually do not cause neurological deficits. Objective: To document our experience with EFCs that needed re-operation and analyze their clinical and radiological findings. Materials and Methods: We describe a series of six cases of symptomatic EFCs following CP that necessitated re-operation in a series of 89 cases over 7 years. Conclusions: EFCs following CP have a different pathogenetic mechanism compared to post-operative epidural hemorrhages. Meticulous surgical techniques can reduce their incidence. Symptomatic EFCs can be evacuated by either re-opening the flap or placing burr holes in the replaced bone. EFCs may become symptomatic even a few days after CP.

Background Cranioplasty following decompressive craniotomy is considered to be a “routine procedure” but several large series have documented a significant amount of both delayed and immediate complications and also a mortality rate of up to 3.6%. Materials and Methods We went through some of the salient complications (excluding seizures) needing resurgery following interval cranioplasty over the past 18 years at our institution in over 300 cases and analyzed the literature that mention these complications and their treatment. Results In addition to the commonly mentioned complications, we found some that had been rarely described or not mentioned hitherto in the literature which we have presented as a pictorial narrative. Based on our experience, we recommend some measures that may decrease the incidence or prevent the occurrence of the same. Conclusions Attention to small but basic surgical techniques will go a long way in preventing unwanted postoperative events.
