| Popis: | A novel supra-temporal technique for retrobulbar anaesthesia in dogs is described and compared to the inferior temporal palpebral approach. Supra-temporal and inferior temporal palpebral retrobulbar injections were performed in 20 orbits of canine cadavers. Distribution of injected contrast medium within the intraconal space and around the optic nerve was analysed using computed tomography. There was adequate distribution of contrast medium within the intraconal space with both techniques. Concurrent intraconal and extraconal distribution was observed using the inferior temporal palpebral approach in 3/10 orbits and using the supra-temporal approach in 5/10 orbits. In 3/10 supra-temporal injections, the injected vehicle was distributed preferentially in the caudal aspect of the retrobulbar cone, closer to the orbital fissure. Accidental intraocular injection was never observed. The supra-temporal approach appears to be a valid alternative to the inferior temporal palpebral approach for retrobulbar anaesthesia in dogs, being less technically challenging. Further studies are required to confirm the clinical efficacy of this approach in dogs. |
