Then, we collected and analyzed CSF drained by puncturing the horizontal fissure. We investigated whether a good operative corridor was obtained with this method.<\/jats:p>\n <\/jats:sec>\n \n RESULTS<\/jats:title>\n The location of the precise horizontal fissure was a mean of 3.97 mm caudal to transverse sinus and the mean amount of CSF drained in 56 patients was 50.4 mL. A good corridor was obtained in 46 (82.1%) of 56 patients without additional cistern puncture.<\/jats:p>\n <\/jats:sec>\n \n CONCLUSION<\/jats:title>\n The puncture of the horizontal fissure can be useful in retrosigmoid approach surgery. Moreover, inexperienced surgeons can use this method to effectively avoid injury of the cerebellum.<\/jats:p>\n <\/jats:sec>","DOI":"10.1093\/ons\/opx048","type":"journal-article","created":{"date-parts":[[2017,6,10]],"date-time":"2017-06-10T01:49:23Z","timestamp":1497059363000},"page":"689-692","update-policy":"https:\/\/doi.org\/10.1097\/lww.0000000000001000","source":"Crossref","is-referenced-by-count":5,"title":["Puncture of Cerebellar Horizontal Fissure for Retrosigmoid Approach: A Prospective and Quantitative Analysis"],"prefix":"10.1227","volume":"13","author":[{"given":"Chang Kyu","family":"Park","sequence":"first","affiliation":[{"name":"Department of Medicine, Graduate School, Kyung Hee University, Seoul, Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Sung Ho","family":"Lee","sequence":"additional","affiliation":[{"name":"Department of Medicine, Graduate School, Kyung Hee University, Seoul, Korea"},{"name":"Department of Neurosurgery, Kyung Hee University Hospital, Seoul, Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Bong Arm","family":"Rhee","sequence":"additional","affiliation":[{"name":"Department of Medicine, Graduate School, Kyung Hee University, Seoul, Korea"},{"name":"Department of Neurosurgery, Kyung Hee University Hospital, Seoul, Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Seok Keun","family":"Choi","sequence":"additional","affiliation":[{"name":"Department of Medicine, Graduate School, Kyung Hee University, Seoul, Korea"},{"name":"Department of Neurosurgery, Kyung Hee University Hospital, Seoul, Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"276","published-online":{"date-parts":[[2017,12]]},"reference":[{"issue":"6","key":"bib1-20240909","doi-asserted-by":"crossref","first-page":"1089","DOI":"10.1007\/s00701-012-1324-2","article-title":"Surgical technique for trigeminal microvascular decompression","volume":"154","author":"Broggi","year":"2012","journal-title":"Acta Neurochir (Wien)"},{"issue":"5","key":"bib2-20240909","doi-asserted-by":"crossref","first-page":"E5","DOI":"10.3171\/foc.2005.18.5.6","article-title":"Technique of microvascular decompression.
