Outcome measures included early (\u22641\u2009month) facial function, long\u2010term (\u22651\u2009year) facial function and extent of resection. Tumor measurements included the greatest dimension, dimension anterior to the IAC axis, dimension posterior to the IAC axis, and a ratio of posterior\u2010to\u2010anterior dimension (PA ratio).<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>A total of 127 patients met inclusion criteria. In early follow\u2010up, 60% patients had good (House\u2010Brackmann I\u2013II), and 40% patients had poor (House\u2010Brackmann III\u2013VI) facial function. In long\u2010term follow\u2010up, 71% patients had good, and 29% patients had poor facial function. A total of 72% of patients underwent gross total resection (GTR) of their tumors. Patients with good facial function had significantly larger PA ratios than patients with poor function both early and long term; however, greatest dimension was the more clearly significant independent predictor of facial outcomes. A larger PA ratio was observed in patients in whom GTR was achieved, but this association was potentially confounded by surgeon preferences and was not statistically significant after controlling for surgical site.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>This study demonstrates that VS position relative to the IAC axis can be used along with tumor size to predict postoperative facial outcomes.
