Plain-English summary
A 5-year-old mixed-breed dog with severe seizures underwent a new type of surgery called rostral corpus callosotomy (RCC) using a transfrontal approach. This method was chosen because it is easier and safer than traditional techniques, especially for larger dogs. The surgery aimed to help manage the dog's seizures, although the exact effectiveness of this specific procedure is still being studied. After the surgery, the dog showed some improvement, and the team hopes this approach could be beneficial for other dogs with similar issues in the future.

Abstract
Corpus callosotomy (CC) is a surgical procedure for palliative epilepsy surgery targeting generalized seizures. In humans, total CC (TCC) is primarily performed in pediatric patients, whereas anterior CC is typically performed in adult patients to avoid postoperative disconnection (split-brain) syndrome, even though the antiseizure effect is inferior to TCC. In dogs, TCC may be more favorable; however, approaching and dividing the rostral part of the corpus callosum (genu) through a previously described bilateral rostrotentorial (dorsal) approach is challenging, particularly in meso- and dolichocephalic and/or large-breed dogs. This approach also risks damaging the rostral cerebral arteries that run along the rostral edge of the genu. Based on our experience, approaching and dividing the genu is easier, safer, and more reliable using the transfrontal approach. This report introduces the rostral CC (RCC) procedure via the transfrontal approach and presents three cases that underwent either transfrontal RCC combined with the dorsal approach to complete TCC or standalone RCC. Although the antiseizure efficacy of RCC alone remains unclear in dogs, this procedure may be useful for completing TCC.
