Evaluating the retro-auricular incision versus reversed question mark incision and Kempe's 'T-bar' incision for decompressive hemicraniectomy

Abstract

Abstract Background The proper decompression for hemicraniectomy depends on intraoperative surgical technique, so the skin incision, on the other hand, is an important variable throughout hemicraniectomy, and there are a variety of cutaneous incisions, including the Kempe T shaped, the reversed question mark and the retro-auricular incisions. We aim to compare those three types of incisions and assess their effects on the surgical outcomes regarding the skull defect size, survived beyond 1 week, post-operative complications and mortality rates. Results A retrospective study included 180 patients were separated into three age- and sex-matched groups according to the type of incision used for their hemicraniectomy. Data including age, sex, causes of surgery, comorbidities, the incision type, the defect area of the skull, intraoperative time and estimated blood loss were recruited for all patients. The mortality and morbidity rates at 3 months post-surgery were documented for all patients. There was a significant difference in the operative time, and the intraoperative measures of blood loss, and insignificant differences in the surviving rate after 1-week post-surgery among the three group patients. There were significant differences between the first and third patient groups compared to the second group regarding wound complications, while the first and third groups were comparable. Conclusions The retro-auricular incision is a safe preferable substitute for the reversed question mark and Kempe T-shaped incisions in decompressive hemicraniectomy, due to the better blood flow maintaining, lower rate of post-operative wound complications.
