“…With extensive mandibular trauma, it may be easier to obtain a ventrodorsal (VD) view instead. 22 One of the most important features of the TMJ, evaluated on the DV view, is the region of the TMJ space. This relatively radiolucent space is occupied by articular cartilage and disc.…”

“…However, producing oblique views can be frustrating due to the technical difficulties inherent in their acquisition, and the large number of reported projections reflects this. [22][23][24][25][26] The reader is referred to the standardized radiographic no- FIG. 2.…”

“…5). 22 To see the TMJ in a more end-on orientation, an additional 7-10' lateral "nose-up" rotation has been suggested, resulting in a complex Rt I O"R20"V-LCdDO projection for a lower left TMJ. 25226 We have found an alternative technique for obtaining oblique TMJ views of cats and small breeds of dogs using the parallax effect, which is relatively simple to obtain.…”

The radiographic anatomy of the temporomandibular joint in the dog and cat is described in dorsoventral and oblique projections. The positioning for different oblique views in conventional radiography and technical details of computed tomography are reviewed. Typical radiographic features of craniomandibular osteopathy, dysplasia, luxation, subluxation, fractures, ankylosis, degenerative joint disease, infection, and neoplasia involving the temporomandibular joint are discussed.

“…18 Physical examination in a cat with a unilateral rostrodorsal luxation reveals an asymmetrical malocclusion with the mandibles deviated away from the side of the TMJ luxation (Fig. 14,18,24,25 Fractures of the TMJ may be true intra-articular fractures of the squamous portion of the temporal bone or condylar process of the mandible, or they may be extra-articular fractures of the condylar process or retroarticular process. Bilateral rostral luxation results in slight rostral protrusion of the mandibles.…”

Oral and maxillofacial disorders in the cat can present as an inability to close the mouth and reaching an accurate diagnosis can be challenging if all of the differentials are not systematically considered. This review focuses on the six conditions that commonly result in a cat being unable to close the mouth. Differential diagnoses include: luxation of the temporomandibular joint, fracture of the temporomandibular joint, caudal mandibular fracture, impingement of the coronoid process of the mandible on the zygomatic arch, mechanical obstruction, and neuropathy. Maxillofacial anatomy, including the temporomandibular joint, muscles of mastication and their innervation will be reviewed. This paper primarily focuses on review of the relevant literature describing each disorder and the diagnostic procedures and treatment options that should be considered when evaluating a cat that is unable to close its mouth. Emphasis is placed on the importance of a complete intraoral examination and evaluation of occlusion to allow the clinician to identify the cause for this clinical sign in cats since periodontal disease causing tooth-to-tooth contact is a common and often unrecognized cause for open mouth in cats.

“…A frequently concurrent injury associated with TMJ trauma is mandibular symphyseal separation. 3 For decades, radiography has been the primary method of imaging the canine and feline TMJ, but the complex anatomy of the carnivore skull represents a technical and diagnostic challenge for the radiographer and radiologist. 1 In recent years, other diagnostic techniques, such as computed tomography (CT), 1,[4][5][6] have been used to assess the TMJ structures in the cat.…”

The minute anatomy of the temporomandibular joint (TMJ) is of great clinical relevance in cats owing to a high number of lesions involving this articulation. However, the precise anatomy is poorly documented in textbooks and scientific articles. The aim of this study was to describe, in detail, the TMJ anatomy and its relationship with other adjacent anatomical structures in the cat. Different anatomical preparations, including vascular and articular injection, microdissection, cryosection and plastination, were performed in 12 cadaveric cats. All TMJ anatomical structures were identified and described in detail. A thorough understanding of the TMJ anatomy is essential to understand the clinical signs associated with TMJ disorders, to locate lesions precisely and to accurately interpret the results in all diagnostic imaging techniques.
