Of the patients subjected to the MCFA, 80.7% were characterized by a House-Brackmann (HB) grade I or II outcome, whereas 96.5% of patients undergoing the RSA were characterized by a HB grade I or II outcome (p = 0.001). This difference appeared only for extrameatal tumors when we compared size-matched tumors (58.3% MCFA vs. 98% RSA; p = 0.0006). There was no statistically significant difference in the hearing outcomes upon consideration of hearing preservation as characterized by the modified Sanna classification system involving classes A and B (18.9% MCFA vs. 10.6% RSA; p = 0.122). &lt;i&gt;Conclusion:&lt;\/i&gt; No statistically significant difference in hearing preservation was identified when comparing tumors operated upon via the MCFA versus the RSA. However, our results indicate that a higher risk of facial nerve function impairment exists if the surgery is performed via the MCFA under circumstances where the tumor extends to the cerebellopontine angle.<\/jats:p>","DOI":"10.1159\/000329362","type":"journal-article","created":{"date-parts":[[2011,8,9]],"date-time":"2011-08-09T14:05:52Z","timestamp":1312898752000},"page":"71-81","source":"Crossref","is-referenced-by-count":50,"title":["Analysis
