A cat presented with a temporomandibular joint (TMJ) luxation after a fall from a shelf. Initial attempts to reposition the TMJ at an emergency clinic were followed by a referral to ensure no fractures. The treatment involved the 'button' technique for TMJ stabilization, which was successful after three weeks of esophageal tube feeding. Post-treatment, the cat returned to normal function, although slight TMJ mobility and subluxation were noted. Imaging confirmed no fractures, and Ethilon with 3 buttons was used for stabilization, to be removed in 7-14 days. Follow-up imaging, specifically Cone Beam Computed Tomography (CBCT), was recommended one year later to monitor dental development.
Key Takeaways:
- TMJ Luxation Management: Maxilomandibular Fixation (MMF) was utilized with the 'button' method. It is effective for stabilizing TMJ luxation in cats, allowing for muscle healing while keeping the joint in place.
- Importance of Imaging: Initial imaging confirmed the absence of fractures, and that the TMJ luxation had been replaced. MMF is used to keep the TMJs aligned during the 3-4 week healing period. A longer healing period can result in scarring and permanent inability to open the mouth fully.
- Post-Treatment Care: Esophageal tube feeding and use of a Kitty Kollar were essential components of post-treatment care to allow for feeding along with pain management medication.
- Follow-up: Regular follow-up, including imaging one year later, is important to verify progress. This annual follow-up is good medicine for all patients, even those without trauma. In a 2 million pet study, those with annual anesthetic dental procedures lived 20% longer than those without.
