Abstract

Background

Olfactory groove meningiomas may recur up to 30% of cases. This study focused on the topographic patterns and location of the recurrences and their surgical management.

Methods

Data on topography of recurrences from a single-center surgical series of olfactory groove meningiomas were retrospectively reviewed and analyzed along with data from pertinent literature. Analyzed factors included patient age and sex; extent of resection and management of infiltrating dura and skull base at initial surgery; time to recurrence; clinical presentation at recurrence; size, location, and histology of recurrent tumors; and management of recurrent tumors.

Results

Overall sample included 33 patients, 4 from our series and 29 from the literature. The main reported symptoms at recurrence were visual function deterioration (67%), nasal obstruction (41%), and headache (40%). The recurrent tumor involved the skull base in all cases (100%). Intracranial regrowth and sinus invasion were observed in 84% of cases. Surgery was performed mainly through the same transcranial approach (76%) or combined transcranial-transnasal approach (17%). Although Simpson grade I resection was possible in more than half of patients, a residual intradural tumor (Simpson grade IV) was left in one third.

Conclusions

Recurrences of olfactory groove meningiomas treated by transcranial approach mainly occur at the cranial base, bone, paranasal sinuses, and optic canals. This suggests resecting at the initial surgery the involved dura and bone to decompress the optic pathways. Reoperation should attempt gross total resection, at least in cases with more limited bone invasion.

期刊介绍: World Neurosurgery has an open access mirror journal World Neurosurgery: X, sharing the same aims and scope, editorial team, submission system and rigorous peer review. The journal''s mission is to: -To provide a first-class international forum and a 2-way conduit for dialogue that is relevant to neurosurgeons and providers who care for neurosurgery patients. The categories of the exchanged information include clinical and basic science, as well as global information that provide social, political, educational, economic, cultural or societal insights and knowledge that are of significance and relevance to worldwide neurosurgery patient care. -To act as a primary intellectual catalyst for the stimulation of creativity, the creation of new knowledge, and the enhancement of quality neurosurgical care worldwide. -To provide a forum for communication that enriches the lives of all neurosurgeons and their colleagues; and, in so doing, enriches the lives of their patients. Topics to be addressed in World Neurosurgery include: EDUCATION, ECONOMICS, RESEARCH, POLITICS, HISTORY, CULTURE, CLINICAL SCIENCE, LABORATORY SCIENCE, TECHNOLOGY, OPERATIVE TECHNIQUES, CLINICAL IMAGES, VIDEOS
