Temporomandibular joint (TMJ) dislocation demonstrate a displacement of the mandibular condyle from it functional position within the glenoid fossa and articular eminence. TMJ dislocation is an acute episode can be transformed into chronic dislocation after multiple repeated episodes. Oral surgeon is frequently called for the management of recurrent TMJ dislocation in adults. In pediatric population, TMJ dislocation sometimes caused by trauma or other than trauma related to wide opening of the mouth during vomiting, yawning and dental procedures considerably under general anesthesia. A 3-year-old baby girl came to Emergency department with a complaint of open mouth for the last 6 hours. Initial examination was carried out and patient was sent for CT-Scan. CT-Scan reported an asymmetric soft tissue density mass in retropharyngeal area at the level of C1 and C2, showing more bulk on right side. Some subtle radiolucencies are also identified within the mass.The possibility of a low-density foreign body or retropharyngeal abscess could not be entirely excluded. A quick examination under anesthesia (EUA)was performed to relieve the patient from the abscess/growth. During EUA, they did not find any growth or collection or pus. The patient was sent to oral and maxillofacial surgeon, on initial examination and previous CT Scan findings, TMJ dislocation was diagnosed. In order to completely examine the patient, reduction of the jaw was attempted on chair side. This was achieved by digital manipulation with little effort and the baby’s jaw was secured with Barton’s bandage to prevent repeated dislocation.She continued tablet beclofen for 6 months as prescribed by the paediatrician.
