“…The fractured process is excised if it is ankylosed to the zygomatic arch or to the temporal bone (Shen et al 2013). Fracture of only the coronoid process is rare and may be caused by reflex contraction of the temporalis muscle at the instance of facial trauma (Kale et al 2015) or from physical force causing the coronoid process to strike the ipsilateral posterior maxillary wall (Ogura et al 2016).…”

This report describes the history, clinical signs and treatment of three horses suffering from deviation and immobility of the mandible resulting from fracture of a coronoid process of the mandible.Deviation and immobility resulted from impingement of a callus between the temporal bone and zygomatic arch. Fracture of the coronoid process was identified by using radiography, ultrasonography, computed tomography or a combination of two or more of these imaging modalities. Osteoarthritis of the ipsilateral temporomandibular joint of two horses was identified. All horses were treated by excising the fractured coronoid process, and two were also treated by excising the diseased ipsilateral mandibular condyle. All horses were able to open their mouth more widely immediately after surgery. One horse experienced moderate post-operative haemorrhage, and all had severe shear mouth. Shear mouth was ameliorated gradually over many months by rasping dental overgrowths. Mandibular movement of all horses improved, allowing efficient mastication of feed. One horse was able to be used as a showjumper, one horse was sold at Thoroughbred yearling sales and was lost to follow-up, and one horse died from an unrelated gastrointestinal disease 10 months after mandibular coronoidectomy and condylectomy.

“…MDCT is an effective tool for the detection of maxillofacial fracture location, degree of fragment dislocation, soft tissue edema, and hemorrhage (13)(14)(15)(16)(17)(18). Furthermore, trauma encompasses not only ambulatory patients with suspected maxillofacial fractures but also patients with loss of consciousness.…”

The purpose of this study was to investigate the characteristics of maxillofacial fractures in elderly patients in comparison to young patients. A retrospective study was conducted of 376 patients with maxillofacial fractures who underwent 64 multidetector-row CT (MDCT)procedures. The study patients comprised 81 elderly patients(≥ 60 years)and 295 young patients(<60 years). Age, sex, cause of injury and fracture location according to MDCT were analyzed using the χ 2 test with Fisherʼs exact test. The proportion of male vs female of elderly patients was 55.6% vs 44.4% and that of young patients was 73.9% vs 26.1%(p = 0.002). The causes of injury in the elderly patients were falls, traffic accidents, assaults, and sports incidents (59.3%, 32.1%, 7.4%, and 1.2%, respectively (p < 0.001)). The percentages of cases with mandibular angle fractures, condylar fractures, and median fractures were 3.7% of elderly patients vs 22.4% of young patients(p < 0.001), 63.0% of elderly patients vs 44.4% of young patients(p = 0.004), and 16.0% of elderly patients vs 30.8% of young patients (p = 0.008), respectively. In conclusion, mandibular condylar fractures dominate maxillofacial fractures in the elderly compared with mandibular median and angle fractures.
