Single flap fronto-temporo-orbito-zygomatic craniotomy for skull base lesions.

Surgery was performed, through single flap fronto-temporo-orbito-zygomatic approach in 22 patients with skull base lesions. In two of these patients, this approach was combined with a transpetrosal approach. The pathological spectrum consisted of trigeminal neurofibromas (5), spheno-orbital meningiomas (4), carotico-ophthalmic aneurysms (4), basilar top aneurysms (2), cavernous sinus haemangiomas (2), invasive pituitary tumours (2) and one patient each of metastatic adenocarcinoma of the cavernous sinus, transcranial fungal granuloma and tubercular granuloma of the cavernous sinus. Of the 14 tumours, 10 were excised totally/near totally while a subtotal excision was achieved in four. Removal of the anterior clinoid process facilitated the clipping of all the carotico-ophthalmic aneurysms. One basilar top aneurysm was wrapped and the other clipped. One patient of fungal granuloma died of fungal meningitis and one patient of basilar top aneurysm expired as a result of thalamic infarct. The advantages of this approach included excellent exposure of the skull base lesions, making the dissection distance shorter and wider, minimal brain retraction and easy replacement of the single bone flap.

[Supraorbital craniotomy to approach the sellar and the parasellar regions].

We report on the experience with supraorbital minicraniotomy in a series of 36 operated cases with good results: 31 aneurysms, 4 pituitary adenomas, 1 anaplastic astrocytoma and 1 arachnoid cyst. One death occurred in this series. The technique is detailed. We conclude that the minicraniotomy is a safe method for the treatment of several parasellar pathologies. The efficacy must be evaluated in clinical trials concerning other approaches.

[Carbon dioxide laser and stereotaxic craniotomy].

This article describes the development and contemporary clinical applications for a computer interactive volumetric stereotactic system in CT and/or MRI-based resection of superficial and deep seated intracranial lesions. The carbon dioxide laser was found to be particularly useful in the resection of deep seated lesions by this volumetric stereotactic method for three reasons: 1) the CO2 laser is a convenient tool for removing tissue from the depths of a deep cavity, 2) it is relatively hemostatic, and 3) the precision provided by the CO2 laser renders it safer than other methods for dissecting tumors from important brain tissue, e.g. the internal capsule. The specific clinical methods of the technique: data acquisition, computer based surgical planning, and interactive stereotactic open surgery are discussed. The clinical experience in 500 consecutive cases in the resection of various lesions from specific anatomical areas is presented. Total overall morbidity was 7% and mortality 1%. We have found the technique of most benefit in the resection of histologically circumscribed intra-axial lesions.
