摘要
Abstract Background Skull base dural reflections are complex, and along with various ligaments joining sutures of skull base, are related to most important vessels like internal carotid arteries (ICA), vertebral arteries, jugular veins, cavernous sinus and cranial nerves make surgical approaches difficult and needs thorough knowledge and anatomy for safe dissection and satisfactory patient outcomes. Cadaver dissection is much more important for training of skull base anatomy in comparison to any other subspecialty of neurosurgery, however, such facilities are not available at most of the training institutes more so in low and middle income countries (LMICs). Methods A glue gun (100-watt glue gun, Aptech deals, Delhi, India) was used to spread glue over the superior surface of bone of skull base over desired area (anterior, middle or lateral skull base). Once glue was spread over the desired surface uniformly, it was cooled under running tap water and the glue layer was separated from the skull base. Various neurovascular impressions were colored for ease of depiction and teaching. Result Inferior surface of dural reflections of the skull base is important for understanding neurovascular orientations of various structures entering or exiting the skull base. It was readily available, reproducible and simple for teaching neuroanatomy to the trainees of neurosurgery. Conclusion Skull base dural reflections made up of glue is an inexpensive, reproducible item which may be used for teaching neuroanatomy. It may be useful for trainees and young neurosurgeons especially at resource scarce health-care facilities.
