INTRODUCTION Cerebrospinal fistulas of the clivus region are often a result of prior surgical intervention on the skull base. The localization and size of the fistula determine the appropriate treatment strategy. When flap closure is not possible, the microsuture technique with autograft placement provides favorable outcome. MATERIALS AND METHODS We present a technical report on application of the microsuture technique for clivus region cerebrospinal fluid fistula closure in a patient with prior chordoma treatment and non-specific COVID-19 complications. RESULTS The application of the microsuture technique provided a stable remission of the fistula and complete regression of clinical manifestations. CONCLUSION The microsuture technique for clivus region fistula closure is a potentially valuable alternative to vascularized flap closure.
