Meta Analysis Comparative Study
Stereotactic radiosurgery as the primary treatment for new and recurrent paragangliomas: is open surgical resection still the treatment of choice?
Paragangliomas (PGs) or glomus tumors are rare, and publications comparing treatment alternatives are few. We sought to analyze our experience with stereotactic radiosurgery (SRS), review the literature, and develop treatment guidelines. ⋯ We feel that SRS should be the primary treatment for most new and recurrent PGs. Even some very large PGs are appropriate for SRS. RT remains an appropriate option in some centers, especially those where SRS is not available. PGs occurring in the youngest patients, catecholamine secreting PGs, and PGs causing rapidly progressing neurologic deficits may be more appropriate for open resection. Metastatic PGs may benefit from combinations of chemotherapy and SRS or RT. Treatment guidelines are proposed.

Review Meta Analysis Comparative Study
Endoscopic endonasal versus open transcranial resection of anterior midline skull base meningiomas.
To assess the advantages and limitations of the endoscopic endonasal approach to anterior skull base meningiomas, a minimally invasive approach that avoids extensive bone drilling, brain retraction, and manipulation of nerves and critical vessels, versus open transcranial surgery. ⋯ Based on the current literature, open transcranial approaches for olfactory groove and TS and planum sphenoidale meningiomas still result in higher rates of total resection with lower postoperative CSF leak rates. The endoscopic endonasal approach may be safe and effective for certain skull base meningiomas; careful patient selection and multilayer closure techniques are essential.
