UNASSIGNED: OBJECTIVE Microsurgical treatment of recurrent @entity5513 ( @entity5513 ) is difficult and poses specific challenges. The authors report their experience with 53 cases of surgically treated recurrent @entity5513 . Outcome of these @entity5 was compared to that of primarily operated on @entity5513 . Special attention was given to the facial nerve functional outcome. METHODS A retrospective analysis was performed of the @entity1 who underwent surgery for recurrent @entity5513 at one institution from 2000 to 2013. The preoperative data, intraoperative findings, and outcome in terms of @entity2103 and improvement of the preoperative symptoms were analyzed and compared with those in a control group of 30 randomly selected @entity1 with primarily operated on @entity5513 . A multivariate regression analysis was performed to test the factors that could affect the facial nerve outcome in each group. RESULTS Fifty-three consecutive @entity1 underwent surgery for recurrent @entity5513 . Seventeen @entity1 were previously operated on and received postoperative radiosurgery (Group A). Thirty-six @entity1 were previously operated on but did not receive postoperative radiosurgery (Group B). The overall postoperative @entity2103 was significantly worse in Groups A and B in comparison with the control group (Group C). Interestingly, there was no significant difference in the facial nerve outcome among the 3 groups in @entity1 who had good preoperative @entity2103 . The @entity5 size and the preoperative @entity2103 are variables that significantly affect the facial nerve outcome. Most of the @entity1 showed improvement of the preoperative symptoms, such as trigeminal hypesthesia, gait disturbance, and @entity10 . CONCLUSIONS Complete microsurgical @entity5 removal is the optimal management for @entity1 with recurrent or regrowing @entity5513 . The procedure is safe, associated with favorable facial nerve outcome, and may also improve existing @entity16 .
