    Abstract:

    Objectives  Operative time, previously identified as a risk factor for postoperative morbidity, is examined in patients undergoing benign Cranial Nerve Tumor resection. Design/Setting/Participants  This retrospective cohort analysis included patients enrolled in the ACS-NSQIP registry from 2007 through 2013 with a diagnosis of a benign Cranial Nerve neoplasm. Main Outcome Measures  Primary outcomes included postoperative morbidity and mortality. Readmission and reoperation served as secondary outcomes. Results  A total of 565 patients were identified. Mean (median) operative time was 398 (370) minutes. The 30-day complication, readmission, and return to the operating room rates were 9.9%, 9.9%, and 7.3%, respectively, on unadjusted analyses. CSF leak requiring reoperation or readmission occurred at a rate of 3.1%. On multivariable regression analysis, operations greater than 413 minutes were associated with an increased odds of overall complication (OR 4.26, 95% CI 2.08–8.72), return to the operating room (OR 2.65, 95% CI 1.23–5.67), and increased length of stay(1.6 days, 95% CI 0.94–2.23 days). Each additional minute of operative time was associated with an increased odds of overall complication (OR 1.004, 95% CI 1.002–1.006) and increased length of stay (0.006 days, 95% CI 0.004–0.008). Conclusion  Increased operative time in patients undergoing surgical resection of a benign Cranial Nerve neoplasm was associated with an increased rate of complications.

  • death from a malignant cerebellopontine angle triton Tumor despite stereotactic radiosurgery case report
    Journal of Neurosurgery, 1998
    Co-Authors: Christopher H Comey, Mark R Mclaughlin, Hae Dong Jho, A J Martinez, L D Lunsford
    Abstract:

    Malignant vestibular Nerve Tumors are rare: to date, only three cases have been reported in the literature. The authors report a case of an eighth Cranial Nerve Tumor that progressed 5 years after stereotactic radiosurgery. The patient was a 44-year-old man who underwent stereotactic radiosurgery for a 27-mm cerebellopontine angle Tumor that was discovered on investigation of tinnitus and hearing loss. He developed facial weakness after 5 years, and repeated imaging revealed Tumor enlargement. Despite complete microsurgical excision, the Tumor rapidly recurred locally and subsequently disseminated within the neuraxis. The patient died 1 year after Tumor progression was detected. Histopathological analysis revealed a malignant spindle cell neoplasm with frequent mitotic figures. The presence of positive rhabdoid elements on immunohistochemical studies confirmed that it was a triton Tumor. The authors review the relevant literature concerning the classification and management of malignant vestibular Nerve Tumors and discuss the implications of Tumor progression after stereotactic radiosurgery.
