Preliminary anatomic investigation of three approaches to the equine cranium and brain for limited craniectomy procedures.

The research paper examines three surgical approaches to the horse’s skull and brain for limited craniectomy procedures. These techniques, adapted from small animal surgery and adjusted for anatomical differences, were applied to equine cadavers as a part of an anatomical study. The techniques may potentially help in treating equine brain disorders like abscesses or hematomas, which often occur due to injuries.

Study Methodology

• The study is essentially a descriptive anatomical investigation based on equine cadavers, with seven used in the tests.
• The team used head and neck sections from these cadavers to formulate techniques for exposing parts of the equine brain.
• Three basic approaches were employed during the investigation – rostrotentorial (the rostral part of the tentorium of the brain), suboccipital (underneath the occipital bone), and transfrontal (across the frontal bones).
• These approaches were adapted from their application in small animal surgery practices and were modified to accommodate the anatomical differences in horses.

Results of the study

• The study led to the definition of the rostrotentorial, suboccipital, and transfrontal approaches to the equine skull and brain.
• The locations such as dorsal, caudal, lateral, and rostral elements of the skull and the underlying cerebral cortex can be accessed using these three approaches.
• The dorsal, dorsolateral, and rostral regions of the cerebral cortex were found to be more superficial and easier to access, unlike the extreme caudolateral cerebrum and cerebellum which are complicated by the location of the transverse and temporal sinuses and deep exposure.

Conclusions

• Many cases of equine brain disorders, such as intracranial abscessation or hematoma formation, result from trauma. These disorders can potentially be treated with microbial culture therapy and surgical drainage or decompression via limited craniectomy procedures.
• The improvement in advanced imaging technologies for brain diseases in horses has resulted in earlier diagnosis and more accurate lesion localization. This increased precision has escalated the probability of a horse’s recovery with limited surgical intervention.
• The description of the surgical methods being studied for the equine skull and brain provide critical insights that could be helpful when surgery is indicated.
