Assessment of maxillary and infraorbital nerve blockade for rhinoscopy in sevoflurane anesthetized dogs

A transorbital approach to the maxillary nerve block in dogs: a cadaver study

“…Viscasillas et al (2013) injected 0.5 mL of methylene blue in each of their techniques, as opposed to the 1 mL injected in this study. The volume of dye used in this study was selected to model a typical volume used clinically in patients of this size based on proven efficacy in clinical studies (Cremer et al 2013) and recommended by standard texts (Skarda & Tranquilli 2007;Clarke et al 2014). The larger number of heads used in the earlier study (37 versus 17 in this study) may also have influenced the proportion of nerves stained, further confounding this comparison between the studies.…”

A cadaver study comparing two approaches for performing maxillary nerve block in dogs

“…Cremer et al. (2011) reported a 75% success rate when the percutaneous approach was performed to provide analgesia for rhinoscopy in dogs.…”

“…2009) and is therefore extremely useful for procedures involving the upper dental arcades, rhinoscopy and maxillectomy. To the authors’ knowledge, only one study (Cremer et al. 2011) has evaluated its analgesic effects for rhinoscopy in dogs.…”

Subzygomatic and infraorbital approaches for maxillary nerve blockade in cats’ cadaver

“…Maxillary nerve is a branch of the trigeminal, which provides sensory information to the skin of the upper lips and nostrils, as well as the soft and hard palate, upper teeth, gingiva and maxilla (DELLMANN & MCCLURE, 2008;PERRY et al, 2015). Therefore, maxillary nerve blockade provides anesthesia for selected procedures such as rhinoscopy, maxillectomy and upper teeth extractions (CREMER et al, 2013).…”
