Septic arthritis of the temporomandibular joint (TMJ) in dogs and other mammals is a rare condition. It is typically associated with notable pain, swelling, and difficulty in opening the mouth. Unlike degenerative TMJ disease, septic arthritis requires urgent intervention. The etiology of the condition may include penetrating trauma, an extension of local infection, such as otitis media, or the hematogenous spread of a pathogen. However, the precise cause may not always be identified. Diagnostic imaging with Computed Tomography (CT), cone-beam CT (CBCT), and/or Magnetic Resonance Imaging (MRI) are helpful for honing the definitive diagnosis and formulating a treatment plan. Subsequently, exploratory surgery may be required to obtain samples for culture and sensitivity and histology and to lavage the joint. In this "methods" article, we provide a detailed description of our approach to diagnosis and management of septic TMJ arthritis in four dogs.
犬类及其他哺乳动物颞下颌关节（TMJ）的化脓性关节炎是一种罕见病症。它通常伴有明显疼痛、肿胀以及张口困难。与颞下颌关节退行性疾病不同，化脓性关节炎需要紧急干预。该病症的病因可能包括穿透性创伤、局部感染（如中耳炎）的蔓延或病原体的血源性传播。然而，确切病因可能并不总是能被确定。计算机断层扫描（CT）、锥形束CT（CBCT）和/或磁共振成像（MRI）等诊断性成像有助于明确诊断并制定治疗方案。随后，可能需要进行探查性手术以获取样本进行培养、药敏试验和组织学检查，并对关节进行灌洗。在这篇“方法”文章中，我们详细描述了对四只犬的化脓性颞下颌关节炎的诊断和管理方法。
