All patients underwent surgical treatment by the same surgical team and via the same surgical approach. Endoscopy combined with neuronavigation was used for large, deep-seated tumors extending to the fourth ventricle. Of the 14 patients, total or gross-total removal was achieved in 12 patients and subtotal removal in two patients. There was no incidence of mortality or morbidity in the 14 patients, and all functional outcomes were good to excellent postoperatively. Postoperative magnetic resonance imaging revealed that none of the patients had suffered brain damage or infarction around the cerebellum, brainstem, or occipital lobe.<\/jats:p>\n<jats:p content-type=\"fine-print\"><jats:italic>Conclusions.<\/jats:italic> Although this study was the first in which a specific examination of the efficacy of the occipital transtentorial approach in patients with anterosuperior cerebellar tumors was undertaken, our findings suggest that this surgical approach is very useful, safe, and accurate for removing the primary tumor and evaluating the surrounding anatomy, as well as for determining operative strategy.<\/jats:p>","DOI":"10.3171\/jns.2001.94.6.0927","type":"journal-article","created":{"date-parts":[[2009,5,13]],"date-time":"2009-05-13T17:34:58Z","timestamp":1242236098000},"page":"927-935","source":"Crossref","is-referenced-by-count":25,"title":["Surgical treatment of posterior fossa tumors via the occipital transtentorial approach: evaluation of operative safety and results in 14 patients with anterosuperior cerebellar tumors"],"prefix":"10.3171","volume":"94","author":[{"given":"Reizo","family":"Shirane","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Toshihiro","family":"Kumabe","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yasuko","family":"Yoshida","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ching-chan","family":"Su","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Hidefumi","family":"Jokura","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Kunihiko","family":"Umezawa","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Takashi","family":"Yoshimoto","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1754","reference":[{"key":"b1","series-title":"Surg Neurol","doi-asserted-by":"publisher","first-page":"298","DOI":"10.1016\/0090-3019(88)90161-9","article-title":"Three-quarter prone approach to the pineal-tentorial region.","volume":"29","author":"Ausman","year":"1988"},{"key":"b2","series-title":"Childs Brain","first-page":"145","article-title":"The occipital transtentorial approach to the posterior fossa in the pediatric patient.","volume":"11","author":"Barba","year":"1984"},{"key":"b3","series-title":"Ann Neurol","doi-asserted-by":"publisher","first-page":"601","DOI":"10.1002\/ana.410440405","article-title":"Posterior vermal split syndrome.","volume":"44","author":"Bastian","year":"1998"},{"key":"b4","series-title":"Acta Neurochir","doi-asserted-by":"publisher","first-page":"130","DOI":"10.1007\/BF01417679","article-title":"Surgical management of pineal region tumors.","volume":"134","author":"Bruce","year":"1995"},{"key":"b5","series-title":"Neurosurgery","doi-asserted-by":"publisher","first-page":"226","DOI":"10.1097\/00006123-199802000-00008","article-title":"Endoscope-assisted brain surgery: part 2\u2014analysis of 380 procedures.","volume":"42","author":"Fries","year":"1998"},{"key":"b6","series-title":"Neurol Med Chir","doi-asserted-by":"publisher","first-page":"929","DOI":"10.2176\/nmc.37.929","article-title":"Cerebellar mutism after posterior fossa surgery\u2014two case reports.","volume":"37","author":"Kai","year":"1997"},{"key":"b7","series-title":"Minim Invasive Neurosurg","doi-asserted-by":"publisher","first-page":"153","DOI":"10.1055\/s-2008-1053476","article-title":"Surgical pitfalls in pinealoma surgery.","volume":"38","author":"Kanno","year":"1995"},{"key":"b8","series-title":"J Neurosurg","doi-asserted-by":"publisher","first-page":"141","DOI":"10.3171\/jns.1983.58.1.0141","article-title":"Infratentorial approach to the pineal region in the prone position: Concorde position.
