Topography and morphometry of the infraorbital and mandibular foramen of the common sloth (Bradypus variegatus) for use in the application of perineural anaesthesia.

A local anaesthetic block performed in cranial and mandibular foramina contributes towards analgesia and the reduction of systemic anaesthesia in procedures in the oral cavity. However, anatomical differences between in wild animals may require adaptations to the anaesthetic and surgical manoeuvres of the head used in domestic animals. With that in mind, we aimed to describe the topography and morphometry of the infraorbital and mandibular foramina in Bradypus variegatus, to support perineural anaesthetic approaches in the cranio-mandibular region of this species.
