During 3 months\u2019 observation, the patient showed mostly geotropic or apogeotropic nystagmus due to right canalolithiasis or cupulolithiasis, however, she sometimes showed nystagmus which suggested left horizontal canalolithiasis. We suspected that she suffered from bilateral horizontal canal type benign paroxysmal positional vertigo (BPPV) and performed Lempert\u2019s maneuver for both directions, however, they were ineffective. She underwent canal plugging for right horizontal canal. After surgery she showed no positional nystagmus of right horizontal canal origin. However, apogeotropic nystagmus of the left horizontal canal origin was still observed. This nystagmus changed to geotropic nystagmus and finally disappeared following Lempert\u2019s maneuver for the left side. Bilateral horizontal canal BPPV is difficult to be resolved, probably because physical treatment for one side would move debris to the cupula in the other canal. Canal plugging combined with Lempert\u2019s maneuver to the other side is one treatment option for intractable bilateral horizontal canal BPPV.<\/jats:p>","DOI":"10.1159\/000076056","type":"journal-article","created":{"date-parts":[[2004,3,2]],"date-time":"2004-03-02T16:06:30Z","timestamp":1078243590000},"page":"366-369","source":"Crossref","is-referenced-by-count":18,"title":["Horizontal Canal Type BPPV: Bilaterally Affected Case Treated with Canal Plugging and Lempert\u2019s Maneuver"],"prefix":"10.1159","volume":"65","author":[{"given":"Arata","family":"Horii","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Takao","family":"Imai","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yasuo","family":"Mishiro","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yoshiko","family":"Yamaji","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Kenji","family":"Mitani","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Takayuki","family":"Kawashima","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Takeshi","family":"Kubo","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"127","published-online":{"date-parts":[[2004,2,25]]},"reference":[{"key":"ref1","doi-asserted-by":"publisher","DOI":"10.1097\/00005537-199604000-00015"},{"key":"ref2","doi-asserted-by":"publisher","DOI":"10.1080\/00016489950181882"},{"key":"ref3","doi-asserted-by":"publisher","DOI":"10.1159\/000067567"},{"key":"ref4","doi-asserted-by":"publisher","DOI":"10.1097\/00005537-200201000-00030"}],"container-title":["ORL"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/www.karger.com\/Article\/Pdf\/76056","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/www.karger.com\/Article\/Pdf\/76056","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2025,4,24]],"date-time":"2025-04-24T04:08:56Z","timestamp":1745467736000},"score":1,"resource":{"primary":{"URL":"https:\/\/karger.com\/article\/doi\/10.1159\/000076056"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2003]]},"references-count":4,"journal-issue":{"issue":"6","published-online":{"date-parts":[[2003,12,1]]}},"URL":"https:\/\/doi.org\/10.1159\/000076056","archive":["Portico"],"relation":{},"ISSN":["0301-1569","1423-0275"],"issn-type":[{"value":"0301-1569","type":"print"},{"value":"1423-0275","type":"electronic"}],"subject":[],"published":{"date-parts":[[2003]]}}}
