However, complicated situations such as organized clots or compartmentation may result in recurrent chronic subdural hematoma (CSDH). Herein, we introduce a novel technique by applying an endoscope for tearing the inner membrane and septum, in addition to evacuating the hematoma in the subdural space where in-line visualization is not possible. Patients and Methods: Two hundred and twenty-nine cases of CSDH were enrolled in this study. Of these, 13 patients were treated endoscopically. The 0-degree and 30-degree, 2.7 mm endoscope was applied after a BHC. The arachnoid knife for microsurgery was used to tear the inner membrane to open the compartments. Results: Non-endoscope-assisted operated (non-Endo group) and endoscope-assisted membranectomy patients (Endo group) demonstrated no differences in sex, age, body mass index, trauma, other diseases, or use of anticoagulation agents. Although the surgery time spent for the Endo patients was longer (128.53±49.56 min) than that for the non-Endo group (65.18±32.89 min), no recurrence was found among the Endo group, whereas a higher rate was observed in the non-Endo group. Conclusion: Novel endoscope-assisted membranectomy is a powerful technique capable of reducing recurrence and improving surgical outcomes. ER -
