OBJECTIVE: Although technological advances combined with many surgical innovations have helped to minimize its occurrence, cerebrospinal fluid (CSF) leak still remains to be one of the most common postoperative complications following microvascular decompression (MVD) surgeries. The objectives of this study are 1) to detail our experience with the clinical application of artificial dura mater for the avoidance of CSF leaks in a group of 103 patients who underwent MVD surgeries and 2) to compare the results of CSF leak and deep wound infection between the group with and one without using artificial dura mater.
METHODS: From July, 2002 to June, 2004 217 consecutive patients who underwent MVD surgeries for hemifacial spasm or trigeminal neuralgia in our center were enrolled into this study. Among them, 103 patients underwent the application of artificial dura mater (Neuro-patch) in the surgical closure procedure to prevent postoperative CSF leak. The handling techniques were detailed and the postoperative results were evaluated. The follow-up period was at least 6 months.
RESULTS: No postoperative CSF leak occurred in the group of patients receiving artificial dura mater whereas 6 cases of CSF leak (2 otorrhea, 2 rhinorrea and 2 CSF wound leak) were found in the group not receiving artificial dura mater. There was no statistical difference of wound infection rates found between these two groups, 1.9 % vs. 2.6 %.
CONCLUSIONS: The use of the artificial dura mater in the closure procedure of MVD surgery seems to be a safe and effective way to prevent CSF leaks. However, further investigations on a larger number of cases still need to be done to substantiate its validity.
