Abstract:
Meningiomas of the olfactory groove have generated a significant amount of discussion in the literature regarding preferred surgical approach. Neuropsychiatric dysfunction is one of the most common presenting symptoms, so surgical approaches have focused on the need to minimize further dysfunction, chiefly by reducing retraction on the frontal lobes. We report a case of olfactory groove meningioma treated with a minimally invasive entirely endoscopic technique. The endoscopic endonasal technique represents a possible alternative for suitably selected cases and could be expected to minimize neuropsychiatric sequelae.
Insights
Olfactory groove meningiomas often cause neuropsychiatric issues. A minimally invasive endoscopic endonasal technique may reduce further dysfunction by minimizing frontal lobe retraction.
Area of Science:
- Neurosurgery
- Endoscopic surgery
- Neuro-oncology
Background:
- Olfactory groove meningiomas frequently present with neuropsychiatric symptoms.
- Surgical approaches aim to minimize frontal lobe retraction to prevent further neurological deficits.
Observation:
- A case of olfactory groove meningioma was treated using a minimally invasive endoscopic endonasal technique.
- This approach avoids extensive brain retraction associated with traditional surgeries.
Findings:
- The endoscopic endonasal technique offers a viable surgical option for selected olfactory groove meningioma cases.
- This method potentially reduces the risk of postoperative neuropsychiatric sequelae.
Implications:
- Minimally invasive endoscopic surgery may be a preferred approach for certain olfactory groove meningiomas.
- This technique could lead to improved patient outcomes and reduced long-term neurological deficits.
