How I do it: microsurgical clipping of carotid-ophthalmic aneurysms through minipterional approach with extradural resection of the anterior clinoid process

Abstract

Background. In modern neurosurgery, preference is given to less invasive procedures. A classic example is switching from standard surgical approaches to keyhole approaches, in particular transition from pterional to minipterional approach. In turn, addition of extradural resection of the anterior clinoid process to the minipterional approach significantly expands the range of its indications.Method. The paper analyses the stages and main features of microsurgical clipping of carotid-ophthalmic aneurysms through the minipterional approach with extradural anterior clinoidectomy in patients operated in the Federal Centre of Neurosurgery (Tyumen, Russia) by professor Sufianov.Conclusion. The technique described in this research is a safe surgical approach, which demonstrates the efficacy of adding some skull base surgery elements to keyhole approaches. This type of craniotomy could become a method of choice for many neurosurgical conditions.
