Temporomandibular joint ankylosis caused by intraoral needle in a 3‐year‐old Arabian mare

Summary A 3‐year‐old Arabian mare was referred for evaluation of swelling beneath the tongue, unilateral facial swelling, mandibular abscess drainage, severe oral cavity wounds, anorexia and depression. Radiographic imaging revealed a metallic foreign body located near the caudal molars, adjacent to the laryngeal region. Due to significant trauma‐induced temporomandibular joint (TMJ) ankylosis and severe limitation in mouth opening, surgical access was extremely challenging. After extensive planning, the mare was anaesthetised and after 90 min of delicate manipulation, the foreign object, identified as a needle embedded within the daily forage, was successfully retrieved. Postoperative wound management and medical therapy led to complete recovery over 2 weeks. This case emphasises the importance of considering intraoral foreign bodies in horses presenting with unexplained facial swelling and oral trauma.
