Osseous Remodeling Technique of the Sella Turcica: A New Surgical Option for Primary Empty Sella Syndrome.

Background: Empty sella is an anatomic finding that is usually asymptomatic. However, when patients with empty sella finding present with visual deficits, surgical treatment may be necessary. The main goal of surgery is to elevate sellar content through a transsphenoidal approach.

Gamma knife radiosurgery for benign tumors with symptoms from brainstem compression.

Purpose: This study evaluated the role of radiosurgery in the management of symptomatic patients with brainstem compression from benign basal tumors.

Methods And Materials: Over a 17-year, period 246 patients (202 vestibular schwannomas and 44 meningiomas) with brainstem compression from benign skull-base tumors were managed with Gamma Knife radiosurgery. Median tumor volumes were 3.

Gamma knife radiosurgery for trigeminal schwannomas.

Background: Trigeminal schwannomas are uncommon tumors that may be microsurgically removed in selected cases, albeit with significant risk for new neurological morbidity. We evaluated the role of stereotactic radiosurgery as an alternative for patients with newly diagnosed or residual trigeminal schwannomas.

Methods: The records of 23 patients who underwent radiosurgery for trigeminal schwannoma were reviewed.

Primary empty sella syndrome: the role of visual system herniation.

Background: It has been traditionally accepted that ophthalmologic alterations in cases of primary empty sella syndrome are caused by the herniation of the visual system in the pituitary fossa, but this cannot be stated categorically.

Methods: Two female patients with primary empty sella syndrome and visual field defects were included in this series. The peculiarity of these cases was that in neither of them was there an evident herniation of the visual system.
