Abstract Background Computer-assisted surgical navigation systems were initially introduced for use in neurosurgery and have been applied in craniomaxillofacial surgery for 20 years. The anatomy of the oral and maxillofacial region is relatively complicated and includes critical contiguous organs. A surgical navigation system makes it possible to achieve real-time positioning during surgery and to transfer the preoperative design to the actual operation. Temporomandibular joint ankylosis limits the mouth opening, deforms the face, and causes an increase in dental caries. Although early surgical treatment is recommended, there is controversy regarding the optimal surgical technique. In addition, pediatric treatment is difficult because in children the skull is not as wide as it is in adults. There are few reports of pediatric temporomandibular joint ankylosis surgery performed with a navigation system. Case presentation A 7-year-old Japanese girl presented severe restriction of the opening and lateral movement of her mouth due to a temporomandibular joint bruise experienced 2 years earlier. Computed tomography and magnetic resonance imaging demonstrated left condyle deformation, disappearance of the joint cavity, and a 0.7-mm skull width. We diagnosed left temporomandibular joint ankylosis and performed a temporomandibular joint ankylosis arthroplasty using a surgical navigation system in order to avoid damage to the patient's brain. A preauricular incision was applied, and interpositional gap arthroplasty with temporal muscle was performed. After the surgery, the maximum aperture was 38 mm, and the limitation of the lateral movement was eliminated. Conclusions A navigation system is helpful for confirming the exact target locations and ensuring safe surgery. In our patient's case, pediatric temporomandibular joint ankylosis surgery was performed using a navigation system without complications.

Objective: To present a case of bilateral temporomandibular joint ankylosis that was managed successfully through gap arthroplasty. Methods: Design:   Case report Setting:   Tertiary Government Hospital Patient:   One Results: A 25-year-old man presented with inability to open his mouth for 18 years after direct trauma to his chin.  CT scan showed bilateral bony fusion of condyles to glenoid fossae, hypertrophic sclerosis and fusion of the condylar heads to the temporal bones. He underwent bilateral gap arthroplasty via preauricular approach with creation of a 15 mm space on the mandibular fossa. As of latest follow up, the patient maintained an inter-alveolar distance of 30 mm for 5 months postoperatively, through continuous aggressive mouth opening exercises. Conclusion:      Gap arthroplasty may be an efficient procedure for temporomandibular joint ankylosis in achieving satisfactory post-operative inter-alveolar opening and articular function. Early and meticulous rehabilitation is required to prevent relapse. Long-term follow up is recommended to document possible recurrence.   Keywords: temporomandibular joint ankylosis, gap arthroplasty, TMJ ankylosis, ankylosis

Joint Ankylosis

Introduction: The temporomandibular joint ankylosis is the union between the surface of the temporal bone in its articular portion and the complex made out of articular disk and the condyle. Its etiology is multifactorial being the trauma with condylar fracture most cited. This alteration causes several functional disorders to the patient, among them the main one is the limitation of mouth opening, which causes difficulty eating, speaking, hygiene, speech and others. The diagnosis is made through a clinic image test. The goal is to show a report of case of ankylosis as well as a literature review.

ABSTRACTTemporomandibular joint ankylosis which is most frequently caused by trauma, presents with restriction in mouth opening in early stages and if children are the victim and not treated early, it presents with growth retardation of the involved mandibular side. Various methods are available for surgical correction. We have reviewed our experience with the efficacy of different interpositional materials in post-traumatic cases in our set up with special reference to temporal fascia over last three years. Twenty seven patients with history of trauma, mostly fall from height, have been studied. They were evaluated clinically and by computed tomography (CT) scan, orthopantogram and x- ray lateral oblique view. The most common age group was 10-15 years with mean 12.5 years and male to female ratio 1:2. Preoperative mouth opening (inter incisor distance) was 1-2 mm in 17 cases and 2-4 mm in 10 cases. We have used temporalis fascia in nine, costochondral graft in seven, silastic sheets in five and T-plates in six cases. Post-operatively, adequate mouth opening of 30-50 mm was observed in six months follow-up and more than 50 mm at one year follow up in 21 cases out of which nine cases have interpositional material as temporalis fascia alone. The postoperative period was uneventful in all cases and none required re-operation for recurrences. We conclude that interpositional arthroplasty, especially with pedicled temporal fascia, is the best method to prevent recurrences and establish good mouth opening and full range of jaw movements.

Joint Ankylosis

A 2-year-old boy was brought by his parents with complaints of difficulty in mouth opening for the past one and half years. He had difficulty in chewing and was malnourished, with developing facial asymmetry. He was diagnosed with right side temporomandibular joint ankylosis. We planned for surgical removal of the ankylotic mass. But we modified the treatment protocol. Instead of doing coronoidectomy after aggressive excision of the ankylotic mass as advocated by Kaban, we did a ‘coronoidoplasty’ after aggressive excision of the ankylotic mass. Coronoidotomy or coronoidectomy is one of the rungs in the treatment ladder that is followed in surgical management of temporomandibular joint ankylosis. But one of the postoperative complications after coronoidectomy is the open bite. The difficulty to close the mouth becomes more pronounced when bilateral coronoidectomy is done. However, ‘coronoidoplasty’, as we have done for this patient retains the action of the temporalis muscle on the mandible in closing the mouth, yet removes the mechanical interference of the coronoid process. Postoperatively the patient was able to clench his teeth well, chew properly and there was no open bite.
