Abstract:
Objective To introduce a new method of trans-superior limb of cerebellopontine fissure approach for exploring and managing superomedial responsible vessels of facial nerve of patients with hemifacial spasm.Methods Clinical data of 21 patients with hemifacial spasm among 183 consecutive patients were analyzed retrospectively in our hospital from February 2009 to December 2013.Dissection of the superior limb of the cerebellopontine fissure was performed to explore the distribution and the severity of compression of the superomedial responsible vessels of the facial nerve,and microvascular decompression was performed.Results Neurovascular compression was found in all of the patients,primary responsible vessels were found in 13 patients,and secondary responsible vessels were found in 8 patients.Complete spasm alleviation was achieved immediately after operation in 18 patients,and complete spasm alleviation was achieved in all of the patients 3 months after operation.No severn complications occurred and no patient died.No recurrence was noted after an average 56 months of follow-up.Conclusion The trants-superior limb of cerebellopontine fissure approach could avoid the defects of standard suboccipital retrosigrnoidal approach,which allows easy identification and management of the superomedial responsible vessels of the facial nerve of patients with hemifacial spasm;thus,high consistent successful rate and low complication rate could be found.
