Functional outcome and morbidity after microsurgical resection of spinal meningiomas

Abstract

OBJECTIVE The aim of this study was to evaluate functional outcome, surgical morbidity, and factors that affect outcomes of surgically treated patients. METHODS The authors retrospectively analyzed patients who underwent microsurgical resection for spinal meningiomas between 2009 and 2020. Patient data and potential variables were collected and evaluated consecutively. Functional outcomes were evaluated using univariate and multivariate analyses. RESULTS A total of 119 patients underwent microsurgical resection of spinal meningioma within the study period. After a mean follow-up of 25.4 ± 37.1 months, the rates of overall complication, tumor recurrence, and poor functional outcome were 9.2%, 7.6%, and 5%, respectively. Age, sex, revision surgery, and tumor recurrence were identified as independent predictors of poor functional outcome. Obesity and surgeon’s experience had an impact on the complication rate, whereas extent of resection and tumor calcification affected the rate of tumor recurrence. CONCLUSIONS Microsurgical resection of spinal meningiomas remains safe. Nevertheless, some aspects, such as obesity and experience of the surgeons that result in a higher complication rate and ultimately affect clinical outcome, should be considered when performing surgery.
