Platelet rich fibrin for post covid nasal swab cerebrospinal fluid leak

Nasopharyngeal swab collection procedure has been used as a part of COVID-19 testing. Few cases of cerebrospinal fluid (CSF) leak following nasopharyngeal swab have been reported so far. Here, we report an interesting case of CSF leak following nasopharyngeal swab for COVID testing which we repaired using platelet-rich fibrin as an outpatient department procedure.
