AimsThe main purpose of this study is to underline the factors which are likely to increase the risk of a sixth nerve injury after percutaneous balloon compression of the gasserian ganglion.MethodsMedical records and intraoperative radiological images of 79 consecutive patients, who underwent percutaneous balloon compression for treating drug-resistant trigeminal neuralgia, were analyzed.ResultsPost-operatively, transient palsy of the sixth nerve developed in 2 patients. According to their intraoperative radiographs, the side effect resulted from irregular balloon shape and inflation of the balloon towards the sellar floor.ConclusionThe anatomic position and the shape of the inflated balloon represent key factors in determining the procedure's benefit or risk of complications.(c) 2009 S.
