Early division of the abducens nerve's prefissural segment: Report of the rarely described variant
Background
The abducens nerve palsy may be associated with various disease processes, as nerve damage may occur at any point of its transit from the pons to the lateral rectus muscle.
Aim
Our case report presents a rarely described variant of the abducens nerve's cavernous segment and an outline of the potential developmental background of the finding.
Case description
Early division of the abducens nerve's prefissural segment was found during the cavernous sinus dissection. The nerve was divided into the superior (of 0.68 mm diameter) and inferior (of 0.54 mm diameter) divisions before reaching the superior orbital fissure just after crossing the internal carotid artery. Both divisions entered the orbit separately through the superior orbital fissure. The innervation of the lateral rectus muscle was typical.
Conclusions
Early division of the abducens nerve can be defined as the presence of two separate nerve trunks in the anterior cavernous sinus, superior orbital fissure, and orbit. Anatomical variations of the abducens nerve should be kept in mind during diagnostic and surgical procedures.
期刊介绍:
Translational Research in Anatomy is an international peer-reviewed and open access journal that publishes high-quality original papers. Focusing on translational research, the journal aims to disseminate the knowledge that is gained in the basic science of anatomy and to apply it to the diagnosis and treatment of human pathology in order to improve individual patient well-being. Topics published in Translational Research in Anatomy include anatomy in all of its aspects, especially those that have application to other scientific disciplines including the health sciences: • gross anatomy • neuroanatomy • histology • immunohistochemistry • comparative anatomy • embryology • molecular biology • microscopic anatomy • forensics • imaging/radiology • medical education Priority will be given to studies that clearly articulate their relevance to the broader aspects of anatomy and how they can impact patient care.Strengthening the ties between morphological research and medicine will foster collaboration between anatomists and physicians. Therefore, Translational Research in Anatomy will serve as a platform for communication and understanding between the disciplines of anatomy and medicine and will aid in the dissemination of anatomical research. The journal accepts the following article types: 1. Review articles 2. Original research papers 3. New state-of-the-art methods of research in the field of anatomy including imaging, dissection methods, medical devices and quantitation 4. Education papers (teaching technologies/methods in medical education in anatomy) 5. Commentaries 6. Letters to the Editor 7. Selected conference papers 8. Case Reports
