Mini-Perforated Craniotomy with Subperiosteal Drain for Evacuation of Chronic Subdural Hematoma: A New Technique and Clinical Study

Abstract Purpose  Chronic subdural hematoma (cSDH) is a frequent disease of the elderly with favorable outcomes. The main choice of treatment is surgery. Along with many surgical techniques described for evacuation of cSDH, we are presenting the preliminary outcomes of a novel surgical method, mini-perforated craniotomy with a subperiosteal drain. Materials and Methods  Patients in whom cSDH with thickness of >10 mm was observed in computed tomography (CT) scans with parenchymal compression and/or midline shift were included in this study. Age, sex, complaint, neurological status, and medical history were recorded along with CT findings. Mini-perforated craniotomy was performed on all patients. A subperiosteal drain was used. The postoperative follow-up period was 3 months. Results  Ten cSDH patients who were admitted to Prof. Dr. Cemil Tascioglu City Hospital between December 2020 and May 2021 were included in this study. The mean age was 64.3 ± 6.272, and the most common admission complaint was a headache. Postoperatively, one patient showed acute rebleeding after the operation due to dual anticoagulant therapy. Besides, in 3 months follow-up, rebleeding, subdural or epidural effusion, wound infection, or cosmetic problems were not observed. Conclusion  Mini-perforated craniotomy with a subperiosteal drain may be an alternative method for evacuation of cSDH with low complication rates especially when the hematoma is suspected to be septated.
