GTR resection was the most important factor influencing PFS. According to our results OS of IEs is much worse than that of spinal ependymomas. Our analysis confirms that patients with good pre-operative (McCormick grade 1 and 2) clinical status have significantly better OS than patients with McCormick grade 3 and higher.
Background Clinical examination, including pre- and postoperative assessment of olfaction, is essential in evaluating surgical outcomes in patients with olfactory groove meningiomas (OGMs). A review of a recent series revealed a lack of assessment of olfaction in most of the studies. Tests determining olfactory detection should be used to reveal olfactory dysfunction. Specialized examination techniques (e.g., electro-olfactography, olfactory evoked potentials, and functional magnetic resonance imaging) are currently used in research. Methods Prospective analysis of 13 patients who underwent surgical resection of OGMs from December 2013 to December 2017 was performed. Data on clinical presentation, pre- and postoperative neurologic examinations, complications, recurrences, adjuvant treatment, and follow-up outpatient examinations were recorded. Olfactory function was assessed using the Sniffin' Sticks odor identification test preoperatively, postoperatively, and 1 year after surgery. Results All the meningiomas were resected via unilateral craniotomy, and gross total resection was achieved in all cases. Surgery-related permanent morbidity was 7.7% and overall mortality 0%. For the eight patients with preoperative normosmia, five remained normosmic (62.5%), one deteriorated to hyposmia (12.5%), and two deteriorated to anosmia (25%). For the two patients with preoperative hyposmia, one remained hyposmic and one deteriorated to anosmia. For the three anosmic patients, two remained anosmic, and one improved to hyposmia.The intact olfactory function preoperatively was associated with a better olfactory outcome. Overall, 62.5% of these patients remained normosmic, and none of the hyposmic or anosmic patients normalized their olfaction.Higher meningioma volume is associated with worse olfactory function before surgery (normosmia in 16.7% versus 100.0% in less voluminous) and following the surgery (normosmia in 16.7% versus 57.1% less voluminous).The unilateral surgical approach enabled the anatomical preservation of the contralateral olfactory nerve in 76.9% of our patients. Functional normosmia was achieved in 50% and hyposmia in 30% of these cases. Conclusions Assessment of olfactory function is both vital in preoperative decision making (surgical approach, radicality of resection) and when evaluating surgical outcome. Preoperative normosmia seems to be the most important prognostic factor for functional olfactory outcome. In normosmic patients the olfaction was preserved in 62.5% of cases. Moreover, higher meningioma volume is associated with worse olfactory function before and following the surgery. The greatest advantage of the unilateral surgical approach is anatomical preservation of the contralateral olfactory nerve with a satisfactory functional outcome. These results support a proactive approach, with early surgical resection using a unilateral approach even in cases with less voluminous OGMs that enables the preservation of olfactory function in a significant proportion of patients.
Background: The adoption of health care restrictions due to the COVID-19 pandemic led to the cancellation of elective surgical care. However, the impact on patients is unknown. Objective: To evaluate the psychological and economic impact of the cancellation of scheduled spinal operations. Methods: We identified 50 patients with cancelled surgeries between 16 March 2020 and 24 April 2020. Forty-nine (98%) participants were contacted, with whom the modified WES-Pi questionnaire was filled in during a telephone interview. Results: Of the 49 respondents, 28 (57.2%) were aged <65 years. The most often reported problem (85.7%) was an ongoing limitation in basic daily activities. At least moderate sadness was experienced by 65.3% and disappointment by 73.5% of the patients. More than 80% reported concerns about the continuation and 73.5% about the progression of their symptoms. Out of 27 employees (55.1%), 63% could not work due to severe pain or movement limitation (p < .001). The inability to work was associated with anger (p ¼ .037). The work-related impact of the cancellation was associated with stress (p < .0001) and concerns about continuing the symptoms (p ¼ .004). Two-third of patients would undergo immediate surgery despite the current epidemic situation. Conclusions: The cancellations of elective spinal surgeries have a serious psychological impact on patients. This together with potential economic consequences is especially evident in employees unable to work due to pain or movement disability. The information is beneficial for health management. Every effort should be made to resume planned surgical treatment if the epidemiological situation allows it.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
