Based on whether the VA could be moved ventrally at the lower cranial nerves (LCNs) level, patients were assigned to Group A (movable VA, <jats:italic>n<\/jats:italic>\u2009=\u200972) or B (unmovable VA, <jats:italic>n<\/jats:italic>\u2009=\u200937), and clinical and surgical outcomes and complications on the day of post-surgery and during follow-up were assessed. All patients were followed up ranging from 17 to 24\u00a0months with a mean follow-up period of 21\u00a0months.<\/jats:p>\n              <\/jats:sec><jats:sec>\n                <jats:title>Results<\/jats:title>\n                <jats:p>After a mean follow-up of 21\u00a0months, the total cure rate significantly decreased in all patients compared to that achieved on the day of surgery, and Group A patients exhibited a higher cure rate versus Group B (93.1% vs. 75.7%, <jats:italic>P<\/jats:italic>\u2009=\u20090.015). Group B patients with unmovable VA revealed both higher incidence of surgical complications (45.9% vs. 15.3%, <jats:italic>P<\/jats:italic>\u2009=\u20090.001) and frequency of bilateral VA compression (27% vs. 8.3%, <jats:italic>P<\/jats:italic>\u2009=\u20090.009) versus Group A.
