Comparison of craniotomy and limited membranectomy with conventional techniques in the treatment of chronic subdural hematoma

Background/aim: Chronic subdural hematoma is the most frequently operated on intracranial hemorrhage worldwide. Although sur-gical results are satisfactory, recurrence remains an important problem. In this study, it was aimed to evaluate patients who underwent craniotomy with limited membranectomy (CwLM) in terms of recurrence rate and other complications. Materials and methods: Electronic records of 291 consecutive patients who were operated on at our clinic (Ataturk University Yakutiye Research Hospital) between 2015 and 2020 were retrospectively reviewed. Their radiological images at the time of admission, clinical status, any early postoperative complications, and clinical status at the 6-month follow-up were all evaluated. Results: According to the results of the study, postoperative mortality and morbidity of patients who underwent CwLM were similar to those with minimally invasive methods, and it reduced recurrence, especially in laminar and separated subtypes. Conclusion: It is our belief that CwLM will be an appropriate treatment approach in suitable patients (radiologically detected) in chronic subdural hematoma, where recurrence is an important problem.
