RESUMO
To analyse the outcome of transnasal endoscopic repair of CSF Rhinorrhea in a tertiary care centre. This is a retrospective study conducted on 81 patients who underwent CSF Rhinorrhea repair in a tertiary care hospital for a period of 11 years. Following confirmation of diagnosis using bio-chemical and radiological investigations, all patients underwent transnasal endoscopic repair of CSF Rhinorrhea using a multilayer graft. Patients were followed up for 6 months. The most common etiology in our study was spontaneous CSF rhinorrhea (60.49%) and subjects with BMI > 25.5 kg/m2 were more prone to it. Cribriform plate was found to be the most frequent site of leak in our study (58.02%), followed by fovea ethmoidalis (12.35%). Overall success rate was 96.30%. Transnasal endoscopic approach for cerebrospinal fluid rhinorrhea repair shows good success rate and also offers the advantages of better visualization and identification of site of leak, less complications, rapid postoperative recovery, and low recurrence rate. Transnasal endoscopic CSF Rhinorrhea repair has shown good results in terms of low recurrence rates and high patient satisfaction among other advantages. Hence this approach should be commonly used for CSF rhinorrhea repair by surgeons.
RESUMO
BACKGROUND AND INTRODUCTION: The success of endoscopic skull base surgery is largely based on the effective repair of the skull base defect. A pedicled nasoseptal flap (NSF), described by Hadad-Bassagateguy is the workhorse of contemporary endoscopic skull base repair. We describe a modification in the technique, "double breasting technique," using the bilateral posterior NSF for skull base repair. OBJECTIVE: In this video article, we describe the technique of harvesting bilateral posterior nasal septal flaps and overlaying the flaps in a double breasting technique to cover the skull base defect. The posterior NSF can be used to cover medium to large skull base defects effectively. SURGICAL TECHNIQUE: A 40-year-old female patient presented with headache and decreased vision for 2 months. MRI with gadolinium showed a sellar suprasellar lesion with chiasmal compression. Visual field charting showed bitemporal hemianopia. She underwent endoscopic transnasal transsphenoidal surgery (binostril approach) and complete excision of tumor. Intraoperatively, there was evidence of arachnoid breach with high flow cerebrospinal fluid (CSF) leak. Sella was repaired with fat, fascia, fibrin glue, and overlaid with the bilateral posterior NSF in a double breasting technique, as described in the video. RESULTS: The skull base repair was successful, with no CSF leak postoperatively.
