PURPOSE: We aimed to explore the influence of preoperative gamma knife treatment on the clinical effect of microsurgical resection of vestibular schwannoma.
METHODS: The data of patients who underwent vestibular schwannoma resection in our hospital between November 2010 and December 2019 were retrospectively collected. According to the data collected retrospectively and the inclusion and exclusion criteria, we selected these patients and divided them into Group A (with preoperative gamma knife treatment) and Group B (without preoperative gamma knife treatment). The pre/postoperative clinical manifestations, neurological function grade, postoperative complications, tumor recurrence and increase were collected and compared between the two groups.
RESULTS: There were 40 and 823 patients enrolled in Groups A and B, respectively. There were no significant differences in the general condition, tumor size and side, or neurological performance of the patients in those two groups before the operation. At the last follow-up, the number of patients with poor facial nerve function was 15 (39.5%) in Group A and 170 (20.7%) in Group B (P = 0.021 < 0.05). In Group A and Group B, disequilibrium occurred in 14 (36.8%) patients and 124 (15.1%) patients, respectively, after the operation (P = 0.012 < 0.05). Seven (17.5%) patients had pneumonia in Group A, and 21 (2.6%) patients had pneumonia in Group B (P = 0.04 < 0.05) after the operation.
CONCLUSION: When a patient with vestibular schwannoma undergoes microsurgical surgery, the preoperative history with gamma knife treatment may make recovery from postoperative facial paralysis difficult for the patients, making them more prone to suffer from postoperative disequilibrium and postoperative pneumonia.
