A Prospective Study Comparing Subperiosteal Versus Subdural Drain After Burr-hole Drainage of Chronic Subdural Hematoma

Abstract

Aims: The aim of our study was to perform a comparison between the efficacy of subperiosteal drain and subdural drain, and to evaluate any differences in terms of functional outcome in the treatment of symptomatic CSDH. Materials and Methods: The interventional, prospective, comparative study was undertaken in Department of Neurosurgery of Medica Institute of Neurological Diseases (MIND) in Medica Superspecialty Hospital, Kolkata, between 1st November 2019 to 30th April 2021, with set inclusion and exclusion criteria. Primary outcome was based on recurrence with 6 months. Secondary outcomes were incidence of re-operation and complications. 44 cases were distributed according to computer generated random numbers for the insertion of either drain following evacuation of CSDH. The data were analysed with SPSS software for windows version 21.0. Results: Our study has shown good outcomes in both groups at 3 months and 6 months. P values of Glasgow outcome score at discharge, 1 month, 3 months, and 6 months were 0.064, 0.39, 0.54 and 0.31; none of them were statistically significant. Conclusion: Our study revealed that both SDD and SPD were safe and equally effective in treating symptomatic CSDH with no difference in final outcome. Complete radiological resolution of hematoma was observed in both SDD and SPD groups at 6 months follow up. However, large sample size and controlled study may be done in future for further analysis.
