Use of Autologous Leukocyte-Platelet Rich Fibrin (L-PRF) in Endoscopic Anterior Skull Base Defect Repair-A Newer Graft Material

CSF rhinorrhea secondary to anterior skull base defect may be spontaneous or traumatic (accidental or iatrogenic), spontaneous being common in middle aged, obese females. Nowadays endoscopic technique is gold standard for anterior skull base defect repair. The graft materials available may be autologous (fat, temporalis fascia, fascia lata, septal mucosa, cartilage, middle turbinate), homologous e.g., cadaveric pericardium or allograft e.g. dural substitute. Leukocyte-platelet rich fibrin (L-PRF) is a newer graft material that contain concentrated platelets and doesn’t require any exogenous material or chemical in blood. A prospective study including 31 patients was carried out at tertiary care centre in eastern India, over the period of 2 years. All the surgeries targeted for closure of the anterior skull base defect were performed endoscopically under general anaesthesia. 30 out of 31 (96.77%) patients successfully improved after repair and one patient required revision surgery due to recurrence of disease and was cured after revision surgery. Autologous Leokocyte-plasma rich fibrin (L-PRF) is a newer and cost-effective graft material for the CSF leak repair with good healing property and with a success rate of more than 95%.
