Abstract :Introduction: The objective of this prospective cohort study was to compare the outcomes of a standardized dual range with a prolonged time of drainage to single drain system in the management of intra operative dural tears. Methods: Between 2018 and 2023, 116 patients (16.1%) with intraoperative dural tears were identified from 720 spinal surgeries performed at Eskisehir City Hospital. Patients underwent standardized surgical procedures for spinal stenosis, disc herniation, spondylolisthesis, spinal fractures, tethered cord, and intradural tumors. Following a protocol change in 2020, thirty patients were assigned to Group A (single subfascial drain, 2018-2020) and eighty-six patients to Group B (dual drainage system with subfascial and subcutaneous drains, 2020-2023). Results: The CSF leakage rate was significantly lower in Group B (2.33%) compared to Group A (16.67%) (p=0.042). Success rates, defined as complete resolution without surgical intervention, were higher in Group B (97.67%) versus Group A (83.33%) (p=0.038). The infection rate was 2.33% in Group B and 6.67% in Group A (p=0.452). Mean drainage duration was 7 days in Group A versus 14 days in Group B (p<0.001), with Group B patients achieving earlier hospital discharge (median 3 days, range 2-5) compared to Group A (median 7 days, range 6-9). Both groups were followed for a minimum of 60 days post-surgery. Conclusion: A standardized dual drain system with prolonged drainage time demonstrated superior outcomes compared to single drain system in managing dural tears after spinal surgery, achieving lower CSF leakage rates and higher success rates.
