Bilateral TMJ Dislocation in a 23-month-old Infant: A Case Report

Dislocation of the temporomandibular joint (TMJ) is rare in children. We present the second youngest case reported. Diagnosis was delayed owing to failure to recognize important clinical signs. We outline how this problem can be recognized and treated, and propose radiographic confirmation of the clinical diagnosis which is not necessary if there is no history of direct mandibular trauma. Two new clinical signs are demonstrated. TMJ dislocation is of relevance to all dental professionals because it can occur in the dental chair and because dental professionals are often called upon to manage this condition.

Bilateral temporomandibular joint dislocation following pulmonary function testing: a case report and review of closed reduction techniques

Temporomandibular joint (TMJ) dislocation is not a common presentation to the emergency department (ED) but one that requires prompt diagnosis and reduction. This is the first reported case of spontaneous...

Reduction of prolonged bilateral temporomandibular joint dislocation by midline mandibulotomy

Various surgical procedures have been used to reduce prolonged bilateral dislocation of the temporomandibular joint, but with some complications. A prolonged bilateral dislocation of the mandibular condyle was simply reduced by a midline mandibulotomy without any complications. One year postoperatively, joint function was unimpeded and there was no recurrence of condylar dislocation.

Temporomandibular joint dislocation after use of a laryngeal mask airway

Use of the laryngeal mask airway has not previously been reported to be associated with bilateral temporomandibular joint (TMJ) dislocation. A size 4 laryngeal mask airway was inserted, without difficulty, in a 45-year-old female undergoing breast surgery. As she regained consciousness in the postoperative recovery room, it was noticed that she was unable to close her mouth, complained of bilateral sore temporomandibular regions and her speech was mumbled. Her jaw was not deviated. Anterior bilateral TMJ dislocation was diagnosed clinically. There was no history of previous TMJ dislocation. Successful reduction was done with manipulation directed inferiorly and posteriorly using propofol for sedation. A relocation ‘clunk’ was felt bilaterally and heard. On awakening, the patient was able to close her mouth, move her jaw without difficulty and talk normally. Relocation was confirmed with an orthopantomogram. Use of a laryngeal mask airway predisposes to pharyngolaryngeal trauma [1], sore throat and dysphagia [2], but has not previously been reported to be associated with bilateral TMJ dislocation. There are, however, several reports of bilateral TMJ dislocation associated with anaesthesia [3, 4]. TMJ dislocation occurred with wide opening of the jaw to place an oropharyngeal airway and nasogastric tube in a mechanically ventilated patient undergoing exploratory laparotomy [3]. This incident was preceded by uneventful laryngoscopy for tracheal intubation. TMJ dislocation was reported after thiopental induction but prior to laryngoscopy for tracheal intubation [4]. Wide mouth opening predisposes to bilateral anterior TMJ dislocation, occurring when the condylar heads are forced to a position anterior to the articular eminence away from their resting position within the glenoid fossa. The patient is then unable to close their mouth (the jaw is held in a lowered but central position), has difficulty speaking and experiences pain in the TMJ region bilaterally [5]. A jaw thrust to lift the pharyngeal structures anteriorly facilitates the passage of a laryngeal mask airway into the hypopharynx with less epiglottic contact [6]. Loss of motor response to jaw thrust (to assess depth of anaesthesia for laryngeal mask airway inertion) [7] may predispose to TMJ dislocation, by anteriorly displacing the mandible [8].

Reduction of a chronic bilateral temporomandibular joint dislocation with intermaxillary fixation and botulinum toxin A

A 71-year-old man was referred to the Department of Oral and Maxillofacial Surgery at Westmead Hospital for investigation of limited jaw movement and facial pain after a cerebrovascular event eight weeks previously. He was found to have bilateral dislocations of the temporomandibular joints (TMJ) and was successfully treated with a combination of intermaxillary fixation (IMF) screws and botulinum toxin A.

Bilateral temporomandibular joint dislocation in a 10-month-old infant after vomiting

We describe a case of bilateral dislocation of the temporomandibular joints (TMJ) in a 10-month-old infant. TMJ dislocations can occur after opening the mouth widely with or without direct trauma.

Closed reduction of chronic bilateral temporomandibular joint dislocation: A case report

Attempts at manual reduction under general anesthesia of a chronically dislocated temporomandibular joint were unsuccessful. Light elastic traction was applied to modified dentures, and after 7 weeks the condyles were partially repositioned. Without further active reduction, the condyles were fully reseated by 9 months.

陳旧性がく関節脱臼の２例

Dislocation of temporomandibular joint is usually apparent from deformation of facial configuration, jaw closing disturbance, malocclusion, etc. However, there are some cases in which the failure of reduction in the early stage for some reason or other results in obsolete dislocation which is difficult to repair.We treated 2 cases of obsolete dislocation of temporomandibular joint, with the following results.Case 1 is a 74-year-old female patient who, about 40 days after her visiting the departments of surgery and dentistry for bilateral dislocation of temporomandibular joint, came to our department with a complaint of masticatory disturbance. Closed reduction was performed under general anesthesia, and the patient has since been in satisfactory condition.Case 2 is a 71-year-old male patient who, about 4 months after visiting the departments of dentistry and orthopedics, came to our department with a complaint of jaw closing disturbance. Closed reduction was performed without improvement and, therefore, open reduction was performed under general anesthesia. Because of the operation and the subsequent mouth opening exercise and close follow-up, the patient has had a favorable course to this day.We also made a clinicostatistical analysis of the cases of temporomandibular joint dislocation reported during the decade from 1972 to 1981 in Japan.
