Ultrasound‐guided trigeminal nerve block with contrast‐enhanced <scp>CT</scp> evaluation for extensive oncologic maxillofacial surgery in 7 dogs: a prospective case series

Ultrasound-guided trigeminal nerve block combined with CT imaging provides detailed, in vivo anatomical information regarding injectate distribution before extensive oncologic maxillofacial surgery in dogs. Within the limitations of this small case series, its incorporation into a multimodal anaesthetic protocol was associated with limited intraoperative nociceptive events and minimal use of additional systemic analgesic interventions.
