The Retrosigmoid Craniotomy. A, Cadaverous specimen after retrosigmoid craniotomy in order to perform the far lateral approach. Note the exposition of the whole sigmoid sinus, the vertebral artery, C1 and C2 dorsal roots, the hypoglossus condyle and with its posterior two thirds drilled and the hypoglossus nerve into the hypoglossal canal For technical nuances of patient positioning, exposure and dural opening, refer to the chapter on Extended Retrosigmoid Craniotomy. Figure 4: The curvilinear incision for medium to large size acoustic neuromas has a broader base than the one used for the standard retromastoid craniotomy aimed at microvascular decompression surgery The extended retromastoid craniotomy is the flexible workhorse approach for resection of lesions within the CP angle.This approach can sometimes obviate the need for more involved petrosal osteotomies. The cerebellum should be retracted only parallel to the direction of CN's V and IX to avoid direct traction on CN VIII Microvascular decompression for glossopharyngeal neuralgia: Technique. Glossopharyngeal neuralgia (GN) is a very rare pain disorder characterized by severe, lancinating, paroxysmal pain in the areas supplied by the auricular and pharyngeal branches of cranial nerves (CN's) IX and X. The affected regions can include the external ear canal.

In 1773, John Fothergill was the first to fully describe trigeminal neuralgia in an article presented to the Medical Society of London titled On a Painful Affliction of the Face.In 1829, Charles Bell distinguished the specific functions of the trigeminal and facial nerves and introduced the idea that the paroxysmal pain in trigeminal neuralgia is directly related to nerve dysfunction Retromastoid Craniotomy The Neurosurgical Atlas, by Aaron Cohen-Gadol, M.D..pdf Enregistré dans Dropbox • 27 oct. 2016 16:37 In simple terms, the operative corridor for the extended retrosigmoid approac

The correct placement of the strategic burr hole for a posterior craniotomy to give access to the cerebellopontine angle is paramount in obtaining optimal exposure in this region that Harvey Cushing at one time described as the gloomy corner of neurosurgery. The craniotomy should extend up to the inferior aspect of the transverse. Retrosigmoid transmeatal approach Cushing (1917) on the other hand described a bilateral suboccipital access and stated the unilateral suboccipital approach as disadvantageous.

Left Retrosigmoid Craniotomy for Resection of Cavernous

The suboccipital lateral or retrosigmoid approach is the main neurosurgical approach to the cerebellopontine angle (CPA). It is mainly used in the treatment of CPA tumors and vascular decompression of cranial nerves. A prospective study using navigation registered with anatomical landmarks in order to identify the transverse and sigmoid sinuses junction (TSSJ) was carried out in a series of 30. The classic retrosigmoid craniotomy has been the traditional neurosurgical workhorse for approaching a majority of lesions in the cerebellar-pontine angle; with appropriate microsurgical techniques, this familiar technique can provide adequate access. As the authors have indicated, the literature provides plenty of evidence to demonstrate the.
