The trigeminal nerve root was stimulated through the foramen ovale using the radiofrequency cannula. Antidromic responses were recorded from the target division through supraorbital, infraorbital, and mental foramina electrodes, and an additional electrode at the masseter muscle. Sensory and motor action responses, as well as verbal and masseter contraction responses, were recorded and correlated.<\/jats:p><\/jats:sec>\n<jats:sec>\n<jats:title>Results<\/jats:title>\n<jats:p>The antidromic responses were easily recorded in the target division in all 23 patients, and they were invariably correlated with the patient's verbal responses. The potentials were recorded successively from V1 to V3. The amplitude in each division before and after RFTC showed little difference in response to electrical stimulation with the same current. The motor trigeminal nerve action potentials were recorded in 10 patients; 7 of these patients had postoperative masseter muscle weakness, while the remaining 3 had normal masseter muscle function. Potentials with low amplitudes were usually obtained from neighboring divisions, but no unexpected denervation of any branches was observed. All the patients experienced immediate pain relief after the procedure.<\/jats:p><\/jats:sec>\n<jats:sec>\n<jats:title>Conclusions<\/jats:title>\n<jats:p>This technique is sensitive and easy to apply. The sensory and motor potentials matched the verbal responses and the complications. Although it cannot completely substitute for the patient's verbal response, this approach is helpful in uncooperative patients, and it predicts and reduces the incidence of masseter muscle weakness. The use of these complementary techniques could increase the chances of treatment success.<\/jats:p><\/jats:sec>","DOI":"10.3171\/2014.8.jns132484","type":"journal-article","created":{"date-parts":[[2014,10,3]],"date-time":"2014-10-03T15:46:19Z","timestamp":1412351179000},"page":"1497-1503","source":"Crossref","is-referenced-by-count":18,"title":["Use of sensory and motor action potentials to identify the position of trigeminal nerve divisions for radiofrequency thermocoagulation"],"prefix":"10.3171","volume":"121","author":[{"given":"Bo","family":"Lin","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Xuguang","family":"Lu","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Xinli","family":"Zhai","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Zhigang","family":"Cai","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1754","reference":[{"issue":"2 Suppl Operative","key":"b1-jns132484","series-title":"Neurosurgery","first-page":"259","article-title":"Identifying the trigeminal nerve branches for transovale radiofrequency thermolesion: \u201cno pain, no stress\u201d","volume":"70","author":"Bendersky","year":"2012"},{"key":"b2-jns132484","series-title":"Neurosurgery","first-page":"242","article-title":"Evoked potentials in trigeminal neuralgia","volume":"13","author":"Bennett","year":"1983"},{"key":"b3-jns132484","series-title":"Acta Neurochir (Wien)","doi-asserted-by":"publisher","first-page":"635","DOI":"10.1007\/s00701-004-0252-1","article-title":"Brain stem injury after radiofrequency trigeminal rhizotomy","volume":"146","author":"Berk","year":"2004"},{"key":"b4-jns132484","series-title":"Neurosurgery","doi-asserted-by":"publisher","first-page":"783","DOI":"10.1227\/00006123-199005000-00008","article-title":"Longterm results of percutaneous retrogasserian thermorhizotomy for \u201cessential\u201d trigeminal neuralgia: considerations in 1000 consecutive patients","volume":"26","author":"Broggi","year":"1990"},{"key":"b5-jns132484","series-title":"J Neurol Neurosurg Psychiatry","doi-asserted-by":"publisher","first-page":"419","DOI":"10.1136\/jnnp.49.4.419","article-title":"Intracranial stimulation of the trigeminal nerve in man.
