Cranioplasty, like any other surgical procedure also comes with risk of complications and failure. Failure of cranioplasty may be early or delayed and further can be attributed to the surgical procedure itself or to the reconstruction material used for the procedure. The aim of this clinical audit is to analyze the causes of failure of 14 cases of cranioplasty procedure. This retrospective study analyses the causes of failure of 14 cases of cranioplasty over 8 ​years ​at a tertiary care centre and identifies major etiological factors for failure including local and systemic. Further, a correlation between the reconstruction material used for cranioplasty and failure was studied along with other attributable factors such as systemic status of the patient and other local factors. The study established that there exists a correlation between failure and the biomaterial used for reconstruction. Various etiological factors like infection, flap break down, fixation protocol and foreign body were identified along with time frame of failure. After failure of cranioplasty, feasibility of a secondary cranioplasty has also been factored into this study, with 8 out of the 14 cases being successfully re-operated. Cranioplasty is a technically demanding and demands certain levels of operator skill levels. While formulating a treatment plan for reconstruction of cranial defects, one has to tailor make a strategy considering several factors such as systemic condition of the patient, status of the cranial surgical site, etiology behind craniectomy, choice of reconstruction material, duration from craniectomy and age of the patient. Inspite of best efforts and ideal reconstruction attempts, failures remain a nagging reality.
