Sustained Glycemic Control After Surgical Resection of Olfactory Groove Meningiomas

1

Olfactory groove meningiomas (OGMs) are anterior skull base tumors associated with anosmia and frontal lobe symptoms.
2

A retrospective study showed postoperative glycemic control improvements in patients with OGMs and diabetes after surgical resection.
3

Mean HbA1c levels decreased significantly from 9.2% to 6.4% within the first 9 months post-surgery.
4

The reduction in HbA1c levels remained durable, with sustained improvements observed up to 36 months after surgery.
5

Metabolic improvements occurred independently of changes in diabetes medication regimens, suggesting potential systemic benefits from OGM resection.
