AIM An image fusion of 3-dimensional (D) digital subtraction angiography (DSA) and magnetic resonance (MR) images, DSA-MR fusion, can simultaneously visualize both information of the vasculature provided by 3D DSA and of the soft tissues provided by MR images. The authors assessed the usefulness of DSA-MR fusion images concerning the pretreatment evaluation for cerebral arteriovenous malformati...

OBJECTIVE Open microsurgical and endoscopic approaches are the two main surgical options for excision of colloid cysts. Controversy remains as to which is superior. Previous studies consist of small cohort sizes. This topic has not been investigated using national administrative claims data which benefits from larger patient numbers. METHODS Current Procedural Terminology (CPT) and Internatio...

We report a case of successful microsurgical reattachment of an amputated ear. Microsurgical reattachment should be considered whenever possible.

OBJECTIVE Both endovascular coil embolization and microsurgical clipping are now firmly established as treatment options for the management of cerebral aneurysms. Moreover, they are sometimes used as complementary approaches each other. This study retrospectively analyzed our experience with endovascular and microsurgical procedures as complementary approaches in treating a single aneurysm. M...

Anatomy of the Middle Cerebral Artery: The Temporal Branches • Nineteen out of 23 middle cerebral arterial specimens had as the first major branch of the middle cerebral artery a sizable anterior temporal artery; a trunk forming the anterior and middle temporal branches; a trunk forming the anterior, middle, and posterior temporal arteries; or a trunk forming temporal and angular arterial branc...

OBJECT Aneurysms of the vertebral artery (VA) and proximal posterior inferior cerebellar artery (PICA) are rare and challenging lesions, as they are located in front of the brainstem and surrounded by the lower cranial nerves. Many different approaches have been described for their treatment, and have yielded different results. With the use of different examples of lesions, the authors describe...

Progress in the study of skull base anatomy and the different lesions involving it has led to more and more precise knowledge of the site. New diagnostic tools have allowed better definition of various diseases, and the use of an operative microscope and modern surgical instruments have all contributed to the development of microsurgery of the skull base. Refinements in microsurgical techniques...

Robotically assisted microsurgery or telemicrosurgery is a new technique using robotic telemanipulators. This allows for the addition of optical magnification (which defines conventional microsurgery) to robotic instrument arms to allow the microsurgeon to perform complex microsurgical procedures. There are several possible applications for this platform in various microsurgical disciplines. Si...
