“…The abducens nerve has a long intracranial course. It is very vulnerable to direct injury such as bone fracture of the lateral orbital wall or indirect injury mainly caused by stretching mechanism during retraction done in surgical procedures (Romero et al, ). From surgical point of view, the abducens nerve can be stretched between the lateral rectus muscle and the origin of the internal carotid artery where the artery adheres to the nerve.…”

The surgical procedures directed to the orbit are invariably reported to be one of the most challenging procedures of the neurosurgery and it is very important to take measures to protect the ocular nerves. Many researchers have tried to identify safe approaches or safe regions in the orbit but the suggestions and results vary among published studies. The ocular motor nerves are under risk of injury during various approaches to the orbit. Simple but careful attention to potential variations in the origin and anatomical course of the ocular nerves and their relationships to the orbit may help to define "safe zones" during various approaches, thus, help to enhance clinical outcomes. The objective of this review, therefore, is to discuss the surgical anatomy of the orbit with special emphasis on oculomotor, trochlear, and abducens nerves and further emphasize their relationships with a surgical point of view during various approaches directed to the orbit.

“…CN VI is adjacent to these structures. The topographic relations account for the risk of nerve injury as a result of disease processes, such as cerebellopontine angle tumours or neurovascular compressions [13,16,28,36]. In the craniometric measurements taken for the purpose of this study, the shortest distance observed between CN VI and the central part of the internal acoustic opening (including the facial and vestibulocochlear nerves) amounted to 14.4 mm (18.6 mm on average for variations I and II).…”

“…83.15). These additional branches originating in the cavernous sinus may pass over or under the petrosphenoidal ligament (Faik Ozveren et al 2003;Romero et al 2009;Ozer et al 2010). The length of the abducens nerve in its subarachnoid segment was found to range from 12.8 mm to 19.1 mm (Joo et al 2012).…”
