Variações da extensão anterolateral do acesso suboccipital lateral: estudo anatômico

Abstract: RESUMO -Estudamos, em laboratório de microcirurgia, as extensões do acesso suboccipital lateral (ASOL) em sete peças anatômicas, com o objetivo de definir as extensões deste acesso necessárias à abordagem das lesões da região anterolateral do forame magno e do forame jugular. As extensões (ressecção óssea) foram realizadas em cinco estágios progressivos: 1) craniectomia suboccipital retrossigmóidea (ASOL retrocondilar); 2) ampliação da craniectomia com remoção da metade posterior do côndilo occipital (ASOL tra… Show more

“…On the contrary, Spektor et al 23 reported that total resection of the condyle provided very little additional exposure to the anterior FM and did not compensate for the significant level of possible additional morbidity. Silveira et al 24 concluded that the extensions of bone removal should be adapted to the topography of the lesion: the retrocondylar approach for the lateral area of the FM; the partial transcondylar for the anterolateral portion; and the complete transcondylar for the anterior part of the FM. 25,26 A recent review found 657 cases from 29 different neurosurgical centers reveled that in 6 they routinely performed condylar resection, in 4 they tailored the drilling of the condyle and 7 others centers they never resect it.…”

“…Extensive drilling of the occipital condyle, of the lateral mass of the atlas and of the jugular tubercle can lead injury to the hypoglossal nerve, to the VA, and promote spinal instability. 3,6,7,13,14,20,21, [24][25][26] Since our objective has always been to keep the quality of life of the patients a priority, a subtotal removal might represent a very acceptable goal in fibrous or calcified tumors encasing the VA and perforating vessels or adhering to cranial nerves. [4][5][6][7] In these patients, a subtotal tumor resection is recommended, which leaves a thin rim of the tumor.…”
