According to clinical manifestations and radiological images, posterior petrous meningiomas were classified into three types: type I (cerebella type; 12 patients), tumours involved and compressed the cerebellum; type II (cranial nerve type; 16 patients), tumours involved the cranial nerves; and type III (combined type; 14 patients), tumours involved more than one structure such as the cerebellum, cranial nerves and the brain stem. All patients underwent microneurosurgery and the total resection rate was 90%. It was more difficult totally to resect type II and III tumours than type I tumours and the post-operative functional outcomes were worse. Microneurosurgical techniques and skills are critical to increase the total resection rate of posterior petrous meningiomas in order to decrease the mortality and disability rates.<\/jats:p>","DOI":"10.1177\/147323000903700341","type":"journal-article","created":{"date-parts":[[2013,2,27]],"date-time":"2013-02-27T14:22:43Z","timestamp":1361974963000},"page":"949-957","source":"Crossref","is-referenced-by-count":5,"title":["The Classification of Posterior Petrous Meningiomas and Its Clinical Significance"],"prefix":"10.1177","volume":"37","author":[{"given":"FJ","family":"Qu","sequence":"first","affiliation":[{"name":"Department of Neurosurgery, Qilu Hospital, Shandong University, Jinan, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"XD","family":"Zhou","sequence":"additional","affiliation":[{"name":"Department of Neurosurgery, Qilu Hospital, Shandong University, Jinan, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"XL","family":"Wang","sequence":"additional","affiliation":[{"name":"Department of the Digestive System, Qilu Hospital, Shandong University, Jinan, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"F","family":"Li","sequence":"additional","affiliation":[{"name":"Department of Neurosurgery, Qilu Hospital, Shandong University, Jinan, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"XD","family":"Lu","sequence":"additional","affiliation":[{"name":"Department of Neurosurgery, Provincial Hospital of Shandong University, Jinan, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"YG","family":"Liu","sequence":"additional","affiliation":[{"name":"Department of Neurosurgery, Qilu Hospital, Shandong University, Jinan, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"YH","family":"Zhong","sequence":"additional","affiliation":[{"name":"Department of Obstetrics and Gynaecology, Shandong Jiaotong Hospital, Jinan, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"HA","family":"Yang","sequence":"additional","affiliation":[{"name":"Department of Neurosurgery, Qilu Hospital, Shandong University, Jinan, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"SL","family":"Ni","sequence":"additional","affiliation":[{"name":"Department of Neurosurgery, Qilu Hospital, Shandong University, Jinan, China"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"179","published-online":{"date-parts":[[2009,5,1]]},"reference":[{"key":"bibr1-147323000903700341","first-page":"1","volume":"104","author":"Castellano F","year":"1953","journal-title":"Acta Radiol"},{"key":"bibr2-147323000903700341","doi-asserted-by":"publisher","DOI":"10.3171\/jns.2004.100.6.1014"},{"key":"bibr3-147323000903700341","doi-asserted-by":"publisher","DOI":"10.3171\/jns.2005.102.2.0284"},{"key":"bibr4-147323000903700341","doi-asserted-by":"publisher","DOI":"10.1016\/S0090-3019(00)00195-6"},{"key":"bibr5-147323000903700341","volume-title":"World Health Organization Classification of Tumours.
