The endoscopic endonasal approach to the Meckel's cave tumors: surgical technique and indications.
Many benign and malignant tumors as well as other inflammatory or vascular diseases may be located in the areas of Meckel's cave or the cavernous sinus. Except for typical features such as for meningiomas, imaging may not by itself be sufficient to choose the best therapeutic option. Thus, even though modern therapy (chemotherapy, radiotherapy, or radiosurgery) dramatically reduces the field of surgery in this challenging location, there is still some place for surgical biopsy or tumor removal in selected cases. ⋯ Percutaneous biopsy using the Hartel technique has been developed for biopsy of such tumors but may fail in the case of firm tumors, and additionally it is not appropriate for anterior parasellar tumors. With the development of endoscopy, the endonasal route now represents an interesting alternative approach to Meckel's cave as well as the cavernous sinus. Through our experience, we describe the modus operandi and discuss what should be the appropriate indication of the use of the endonasal endoscopic approach for Meckel's cave disease in the armamentarium of the skull base surgeon.

We aim to evaluate the complications of spinal cord stimulation (SCS). ⋯ In spite of the existence of several complications, SCS may be seen as a safe technique. Furthermore, the incidence of life-threatening complications is low. The physician must be alert to recognize them during the follow-up. Complications may be avoided or at least diminished by performing a proper and strict aseptic surgical technique as well as carrying out an accurate patient selection before the implantation, according to the recommendations published in the literature.

This article demonstrates the experience with endoscopic transphenoidal anterior skull base surgery for lesions other than pituitary adenomas. The spectrum of lesions, results, and complications are presented. ⋯ The endoscopic anterior skull base approach is highly effective in treating a large variety of lesions other than pituitary adenomas. The adoption of the nasoseptal flap for closure has markedly reduced the incidence of spinal fluid leaks, and is used routinely for lesions that violate the intracranial compartment.

The endonasal route often provides the most direct and safe approach to skull base pathology. In this article we review the literature with regard to management of the paranasal sinuses in the setting of skull base surgery. ⋯ Careful management of the paranasal sinuses throughout the peri-operative course is paramount to optimizing sinonasal function and safety.

To analyze current indications for transsphenoidal pituitary surgery. ⋯ Even as medical and surgical treatment for pituitary tumors evolves, transsphenoidal surgery remains a mainstay of treatment. Outcomes after transshenoidal surgery have improved over time. Neurosurgeons must be aware of the indications, risks and alternatives to transsphenoidal pituitary surgery.
