Potential conditions that could provoke headshaking include dental diseases, osseous and articular disease, and sinusitis, says Nancy S. Loving, DVM. She reviews the findings from a retrospective study of 103 cases of headshaking. CT findings, targeted treatments and treatment success were evaluated.
In her summary, Loving says 94 horses had relevant pathologic findings. The most common diagnosis was trigeminal nerve-mediated headshaking in 62 (60.2 percent) of horses. At least 22 (22.4 percent) of the 103 cases of headshaking had a treatable condition that was resolved with targeted treatment.
