Abstract
Objective: The aim of this study is to share our experience of an effective dural repair technique, which we have utilised to minimise the incidence of postoperative CSF leakage in patients undergoing microvascular decompression (MVD) for trigeminal neuralgia and hemifacial spasm.
Methods: Between 1987 and 2018, 134 patients had microvascular decompression, mainly for trigeminal neuralgia and hemifacial spasm in our unit. All our patients having posterior fossa MVD using the technique described by Janetta, had an apparently watertight repair of the dura at the end of the operation. We describe our technique using Duraguard® and Histoacryl® glue. The post-operative outcome of the duraplasty was assessed retrospectively by case note review.
Results: The results indicated that of 134 patients, 129 (96.2%) had no postoperative CSF leakage. Only fi ve (3.7%) of the patients experienced post-operative CSF leakage (three from the wound, two from the nose).
Conclusion: We conclude that dural repair using the described technique utilising a dural substitute (Duraguard) and Histoacryl glue is safe and effective in preventing post operative CSF leak following MVD.
