The diagnosis of TNMH was based on a combination of positive maxillary nerve block and\/or response to treatment for TNMH. Although TNMH was the most common diagnosis with 62 horses (60.2%) affected, in 22 horses (21.4%), a primary disease process was identified and treatment of the condition eliminated signs of head\u2010shaking. Clinically relevant primary diseases included dental fracture, primary sinusitis, temporo\u2010mandibular joint arthritis, nuchal bursitis, musculoskeletal pathologies, basisphenoid fracture, otitis externa and a mass affecting the infra\u2010orbital nerve.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Main limitations<\/jats:title>\n                    <jats:p>Some clinical information was missing and follow\u2010up information was not obtained in all cases.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>CT was perceived as a useful diagnostic tool by most veterinarians, ruling out significant abnormalities.
