Abstract

Background: We describe, step by step, a modified, less invasive, diamond-shaped mini-craniotomy that optimizes dural opening and can be performed in elderly patients affected by acute subdural or intracerebral hematomas, in therapy with antiplatelets or anticoagulants.

Methods: We retrospectively analyzed the clinical records of 67 patients (mean age of 78.5 years) treated in our institution, during a period of 10 years, with this novel diamond-shaped craniotomy. Seventeen patients were treated for intracerebral hemorrhage and 50 patients for acute subdural hematomas. All the patients were in therapy with antiplatelets or anticoagulants.

Results: Approach-related complications were not detected. Ten of 67 patients (14.9%) presented temporal muscle atrophy; there was no scar deformity, paresthesia, hyperalgesia, or ramus frontalis palsy around the scalp incision. Thirty-day mortality was 22%. The mean follow-up was 1.3 years. One-month postoperative brain computed tomography scans showed a satisfactory hematoma evacuation in 57 of 67 patients (85%).

Conclusions: The diamond-shaped mini-craniotomy for acute subdural and intracerebral hematomas is safe and effective, and it should be considered as an alternative to traditional approaches, particularly in elderly patients.
