Is Unilateral Extended Pterional Craniotomy Preferable Over Bicoronal (Bifrontal) Craniotomy in Large or Giant Olfactory Groove Meningiomas?

Aim: Bicoronal incision and bifrontal craniotomy are commonly used for resecting large (4-6 cm) or giant ( 6cm) olfactory groove meningiomas (OGMs). Although the bifrontal approach provides good bilateral visual access to the anterior cranial fossa, it is associated with the risk of injury to the frontal bridging veins and superior sagittal sinus, infection, and CSF leakage due to the frontal sinus neighborhood.

Material And Methods: This was a retrospective review of 16patients (nine men and seven women) with large and giant OGMs operated through unilateral extended pterional craniotomy between 2010 and 2022.

Posterior laminoforaminotomy in the treatment of lateralcervical herniated disc and foraminal stenosis.

Background/aim: Posterior cervical laminoforaminotomy is an effective surgical treatment in selected cases of cervical radiculopathy caused by posterolateral herniated discs or foraminal stenosis. The aim of the present study was to evaluate the surgical techniques, rates of complications, long-term outcomes, advantages, and disadvantages of keyhole foraminotomy retrospectively.

Materials And Methods: Keyhole foraminotomy was performed in 83 patients.
