The inferior vestibular nerve (IVN) was the nerve of origin in 84 of 359 cases (23.3%), while the superior vestibular nerve (SVN) was the nerve of origin in 36 patients (10%). In 239 of 359 cases (66.6%), the nerve of origin was not identified. Forty patients undergoing hearing preservation surgery had hearing results and nerve of origin data available for review. Functional hearing (&lt;50dB PTA and &gt;50% speech discrimination) was preserved in 10 of 15 patients (75%) with SVN tumors, while only 7 of 25 patients (28%) with IVN tumors retained functional hearing. Facial nerve outcomes and nerve of origin were recorded simultaneously in 109 patients. Seventy\u2010one of 74 patients (95%) patients with IVN tumors achieved a House\u2010Brackmann (HB) grade I\u2013III, while 35 of 35 patients (100%) with SVN tumors retained HB I\u2013III facial function. Looking at tumor size versus hearing preservation, functional hearing was preserved in 22 of 49 patients (45%) with &lt;1\u2010cm tumors, and 4 of 20 patients (20%) with 1\u2010 to 1.5\u2010cm tumors. For all cases with documented facial nerve function, HB I\u2013III were achieved in 96% of SO, 94% of MCF, and 88% of TL procedures.\n                  <\/jats:p>\n                  <jats:p>\n                    <jats:bold>Conclusions:<\/jats:bold>\n                    Our retrospective data indicated that IVN tumors were twice as common as SVN tumors. The nerve of origin did not affect facial nerve outcomes but did impact hearing preservation rates. Patients with tumors &lt;1 cm in size had the best chance for hearing preservation. Overall facial nerve preservation was excellent with &gt;90% achieving HB 1 to 3 function at final follow\u2010up.\n                  <\/jats:p>","DOI":"10.1097\/mlg.0b013e3181453a07","type":"journal-article","created":{"date-parts":[[2009,2,19]],"date-time":"2009-02-19T16:03:32Z","timestamp":1235059412000},"page":"2087-2092","source":"Crossref","is-referenced-by-count":115,"title":["Nerve of Origin, Tumor Size, Hearing Preservation, and Facial Nerve Outcomes in 359 Vestibular Schwannoma Resections at a Tertiary Care Academic Center"],"prefix":"10.1002","volume":"117","author":[{"given":"Abraham","family":"Jacob","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"suffix":"Jr","given":"Lawrence L.","family":"Robinson","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jared S.","family":"Bortman","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Lianbo","family":"Yu","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Edward E.","family":"Dodson","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"D Bradley","family":"Welling","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2009,1,2]]},"reference":[{"key":"e_1_2_7_2_2","doi-asserted-by":"publisher","DOI":"10.1097\/00005537-199802000-00005"},{"key":"e_1_2_7_3_2","doi-asserted-by":"publisher","DOI":"10.1097\/00129492-200209000-00022"},{"key":"e_1_2_7_4_2","doi-asserted-by":"publisher","DOI":"10.3171\/jns.2005.103.1.0059"},{"key":"e_1_2_7_5_2","doi-asserted-by":"publisher","DOI":"10.1001\/archotol.1978.00790090050011"},{"key":"e_1_2_7_6_2","doi-asserted-by":"publisher","DOI":"10.1288\/00005537-198109000-00015"},{"key":"e_1_2_7_7_2","first-page":"10","article-title":"Relative frequency of inferior vestibular schwannoma.","volume":"99","author":"Clemis JD","year":"1989","journal-title":"Arch Otolaryngol Head Neck Surg"},{"key":"e_1_2_7_8_2","doi-asserted-by":"crossref","unstructured":"OkadaY TakahashiM SaitoA KanzakiJ.Electronystagmographic findings in 147 patients with acoustic neuroma.
