Retrograde Approach to Maxillary Nerve Block: An Alternative in Orofacial Surgeries in Horses.

Animals (Basel) 2022 May 27;12(11). Epub 2022 May 27.

Department of Veterinary Medicine, University of Perugia, 06126 Perugia, Italy.

The aim of this study was to retrospectively report outcomes resulting from the approach to the maxillary nerve block (MNB) through the infraorbital canal, in terms of needles selection, drawbacks or side effects during or after block execution, and analgesic efficacy leading to clinical and cardiovascular stability during surgery. Anesthetic records of 15 horses undergoing orofacial surgery in standing analgo-sedation (STA, = 6) and in general anesthesia (GEN, = 9) were retrieved and analyzed. Horses in group STA required surgery for dental extraction, nasal polyp resection and maxillary/frontal sinusitis. Read More

Cardiopulmonary Effects and Pharmacokinetics of Dexmedetomidine Used as an Adjunctive Analgesic to Regional Anesthesia of the Oral Cavity with Levobupivacaine in Dogs.

Animals (Basel) 2022 May 9;12(9). Epub 2022 May 9.

Small Animal Clinic, Veterinary Faculty, University of Ljubljana, 1000 Ljubljana, Slovenia.

This study investigated the cardiopulmonary effects and pharmacokinetics of dexmedetomidine (DEX) used as an adjunctive analgesic for regional anesthesia of the oral cavity with levobupivacaine in anesthetized dogs.

Clinical techniques in veterinary dermatology Regional anaesthesia of the canine and feline nose.

Vet Dermatol 2022 Jun 7;33(3):258-262. Epub 2021 Dec 7.

The Royal Veterinary College, Hawkshead Lane, Hatfield, AL9 7TA, UK.

Local anaesthesia techniques are now essential parts of the multimodal analgesic approach applied in the care of small animals. The sensory innervation of the nose is provided by the maxillary division of the trigeminal nerve, so nasal pain can be prevented or alleviated by blocking branches of this nerve. Maxillary or infraorbital nerve block can be used if invasive procedures are performed on the nose of the canine and feline patients. Read More

Mechanisms Underlying the Selective Therapeutic Efficacy of Carbamazepine for Attenuation of Trigeminal Nerve Injury Pain.

J Neurosci 2021 10 26;41(43):8991-9007. Epub 2021 Aug 26.

Department of Neurological Surgery, School of Medicine, University of Pittsburgh, Pittsburgh, Pennsylvania 15213

Different peripheral nerve injuries cause neuropathic pain through distinct mechanisms. Even the site of injury may impact underlying mechanisms, as indicated by the clinical finding that the antiseizure drug carbamazepine (CBZ) relieves pain because of compression injuries of trigeminal but not somatic nerves. We leveraged this observation in the present study hypothesizing that because CBZ blocks voltage-gated sodium channels (VGSCs), its therapeutic selectivity reflects differences between trigeminal and somatic nerves with respect to injury-induced changes in VGSCs.

Increased expression of Netrin-4 is associated with allodynia in a trigeminal neuropathic pain model rats by infraorbital nerve injury.

PLoS One 2021 29;16(4):e0251013. Epub 2021 Apr 29.

Department of Molecular Neuroscience, Osaka University Graduate School of Medicine, Suita, Osaka, Japan.

Neuropathic pain refers to pain caused by lesions or diseases of the somatosensory nervous system that is characteristically different from nociceptive pain. Moreover, neuropathic pain occurs in the maxillofacial region due to various factors and is treated using tricyclic antidepressants and nerve block therapy; however, some cases do not fully recover. Netrin is a secreted protein crucially involved in neural circuit formation during development, including cell migration, cell death, neurite formation, and synapse formation. Read More

Computed Tomography Analysis of the Feline Infraorbital Foramen and Canal.

Front Vet Sci 2020 27;7:619248. Epub 2021 Jan 27.

College of Veterinary Medicine and Biomedical Sciences, Colorado State University, Fort Collins, CO, United States.

Feline skull anatomic variation is plain to see with casual observation. Obtaining an in-depth understanding of this anatomic variability is critical to performing safe and effective regional anesthesia for dental procedures and maxillofacial surgeries. Maxillofacial anatomic variability is proven to impact the placement and efficacy of nerve blocks in dogs and horses, but similar studies have not been performed in cats. Read More

Craniofacial neuralgias.

NeuroRehabilitation 2020 ;47(3):299-314

Physical Medicine and Rehabilitation, Indiana University School of Medicine, Rehabilitation Hospital of Indiana, 4141 Shore Drive, Indianapolis, IN, USA.

While non-headache, non-oral craniofacial neuralgia is relatively rare in incidence and prevalence, it can result in debilitating pain. Understanding the relevant anatomy of peripheral branches of nerves, natural history, clinical presentation, and management strategies will help the clinician better diagnose and treat craniofacial neuralgias. This article will review the nerves responsible for neuropathic pain in periorbital, periauricular, and occipital regions, distinct from idiopathic trigeminal neuralgia. Read More

Department of Chemical and Biomolecular Engineering, Hong Kong University of Science and Technology, Hong Kong, Hong Kong.

Although various cases of neuralgia and its treatments have been reported, not enough evidence is present to recommend a single type of treatment as the most effective. The patient we have dealt with experienced significant interferences in his daily life due to chronic allodynia, but the symptom could not be resolved via previously reported treatments. We report a case of which a patient who presented infraorbital neuralgia after trauma was successfully treated by a novel treatment strategy. Read More
