A ring electrode to record extraocular muscle activities during skull base surgery

Acta Neurochir (Wien). 1992;117(1-2):66-9. doi: 10.1007/BF01400639.

Abstract

A ring-shaped electrode was developed and used in 20 patients to record evoked electromyographic responses directly from the extraocular muscles during skull base surgery. Intra-operative monitoring with this electrode helps the surgeon to localize the nerves that innervate the extraocular muscles precisely and to refrain from disturbing important neural structures during operations. Such monitoring also provides some insight into the pathophysiology of the dysfunction of these nerves resulting from skull base lesions.
