“…Once lifting, the head is positioned at a level above the right atrium; extension and rotation depend on the condition being operated; and in torsion, the angle formed by the head, neck and shoulder should be higher, so as to offer the surgeon to be in a closer lateral position with respect to the surgical area, in order to become parallel to the Sylvian fissure. Most of times, intending to expose higher brain pathologies, we should position the head in more extension to provide inferior to superior microsurgical view 18 . Care must be taken so that the jugular veins remain compression-free throughout surgery, to prevent delay of venous emptying, brain swelling, and increased bleeding in the operating field.…”

Objective Didactically describe the orbitozygomatic craniotomy made in three pieces. Method This approach was performed, from 2002 to 2011, in 49 patients admitted at Beneficência Portuguesa of São Paulo Hospital. Results Twenty-seven patients had vascular lesions and twenty-two suffered for intracranial skull base tumors. The vascular lesions varied from cavernous angiomas inside the mesencephalum, high bifurcation basilar tip aneurysms, superior cerebellar arteries aneurysms and arteriovenous malformations in the interpeduncular cistern. Skull base tumors as meningiomas, interpeduncular hamartomas and third ventricle floor gliomas were among the neoplastic lesions approached. We had no permanent injuries and minimal transient complications had occurred. Conclusion It is a descriptive text, organized in the sequence of the main stages in which such a craniotomy is performed, describing in details the technique in which this group of evolutionarily authors came to accomplish the task.

“…It is usually accomplished through a pterional craniotomy associated to partial resection of the orbit's roof and intradural anterior clinoidectomy for exposure of the ICA clinoid segment 1,2,5,6 . Since these aneurysms present an intimate relationship with the skull base, head extension should be avoided in order to maintain the ICA in the most superficial position as possible and not to hide the aneurysm neck 7,9,10 .…”

“…The neurosurgeon's visualization of deep arterial and nervous structures can be influenced importantly by the patient's head position 2,3 , which should provide the temporal and frontal lobes to be ideally side-by-side and avoid them to overlap. It also affects the exposure of the anterior clinoid process and the view along the orbital roof 2,4,5 . In 1976, Yasargil described the positioning of the head for aneurysms of the anterior circulation but did not report the reason for each angle degree of rotation and extension 6 .…”

Objective: To study the ideal patient's head positioning for the anterior circulation aneurysms microsurgery. Method: We divided the study in two parts. Firstly, 10 fresh cadaveric heads were positioned and dissected in order to ideally expose the anterior circulation aneurysm sites. Afterwards, 110 patients were submitted to anterior circulation aneurysms microsurgery. During the surgery, the patient's head was positioned accordingly to the aneurysm location and the results from the cadaveric study. The effectiveness of the position was noted. Results: We could determine mainly two patterns for head positioning for the anterior circulation aneurysms. Conclusion: The best surgical exposure is related to specific head positions. The proper angle of microscopic view may minimize neurovascular injury and brain retraction.Keywords: cerebral aneurysm, head positioning, anatomical landmarks, anterior circulation arteries, microsurgery. RESUMOObjetivo: Estudar o posicionamento da cabeça para a cirurgia de aneurismas cerebrais da circulação anterior. Método: Dividimos o estudo em duas partes. Inicialmente, dez cabeças de cadáveres frescos foram posicionadas e dissecadas de modo a expor, de maneira ideal, os principais sítios de aneurismas na circulação anterior do cérebro. Posteriormente, 110 pacientes foram submetidos a microcirurgia para clipagem de aneurismas cerebrais da circulação anterior. Durante as cirurgias, as cabeças foram posicionadas de acordo com a localização específica de cada aneurisma e o resultado obtido no estudo dos cadáveres. Cada paciente teve sua posição avaliada quanto a sua eficácia. Resultados: Obtivemos basicamente dois padrões de posicionamento da cabeça para cirurgias de aneurismas cerebrais da circulação anterior. Conclusão: A melhor exposição cirúrgica está relacionada à posição específica da cabeça para cada localização aneurismática. O ângulo de visão microscópica adequado minimiza lesões neurovasculares e a excessiva retração cerebral.Palavras-chave: aneurisma cerebral, posicionamento da cabeça, reparos anatômicos, artérias da circulação anterior, microcirurgia.

“…The pretemporal craniotomy, as described in this Number of the Arquivos de Neuro-Psiquiatria, by Chaddad-neto et al 4 presents us with a typical example of those quantum improvements which mark the history of neurosurgery. Treading the path paved by "larger-than-life" neurosurgical personalities such as Yasargil and Drake, the pretemporal approach expands and complements Yasargil's and Drake's classic signature techniques 5,6 , uniting several of their advantages while overcoming most of their technical drawbacks.…”
