Outcome of craniotomy and membranectomy in the management of chronic subdural haematoma recurrence: A series of 17 patients

Abstract

Background: Chronic subdural hematoma (CSDH) is a proportionally frequent neurosurgical pathology, and burr hole craniotomy is the most commonly used procedure in its treatment. However, currently, there is no real consensus on its management, especially recurrences. Many authors forwarded each management modality for the recurrence of CSDH; bone flap craniotomy was less frequently defended. Aims and Objectives: we aim to confirm the superiority of bone flap craniotomy with membranectomy over other techniques in the management of CSDH recurrences. Materials and Methods: We studied retrospectively 17 patients operated on at our department from February 2016 to February 2020, for particular situations of CSDH recurrence. Results: 17 patients with recurrent chronic subdural hematomas were operated on with bone flap craniotomy and membranectomy; with main age of 67 years old. Only one patient (5.8 %) presented recurrence of the hematoma after bone flap craniotomy. We have got one case (5.8%) of suspect osteitis on the bone flap managed successfully. Unfortunately, one patient in this series died. Conclusion: In careful surgical hands, the bone flap is not more harmful than other surgical procedures and it is found to be effective in CSDH recurrence management.
