Abstract: ankylosis of the temporomandibular joint is characterized by restriction or limitation of mandibular movement. it presents as a classic symptom a limited range of motion on opening. radiographically, ankylosis presents features that facilitate the diagnosis. however, its visualization is not clear in most of the cases involving conventional radiographic techniques. with the evolution of radiographic techniques, computed tomography (ct) became an important examination in the diagnosis of the ankylosis of temporomandibular joint. due to the increasing use of the ct and its importance in the diagnosis of this disease, the aim of this paper is to present and describe tomographic images of ankylosis of this joint by presenting two clinical cases, using several slices as axial, coronal, and three-dimensional reformatted images.

Abstract: condylar damage can produce temporomandibular joint ankylosis. if ankylosis ocurrs in early childhood can develope facial asymmetry or mandibular hypoplasia. in these cases, several therapeutic options have been used, but distraction osteogenesis offers a new excellent alternative because it allows elongation of soft tissues and can be performed in childhood. we present a bilateral temporomadibular joint ankylosis in a 9 years old girl, who was treated by means an arthroplasty and extraoral distraction devices, only for elongation of soft tissues and keeping space between skull base and mandibula to avoid reankylosis and to allow condylar remodelation.
Surgery of temporomandibular joint under local anaesthesia

Indian Journal of Plastic Surgery , 2008,
Abstract: Temporomandibular joint ankylosis is a debilitating disorder arising from an inability to open the mouth. This leads to poor nutrition, poor dental hygiene, and stunted growth. Anaesthesia, especially general anaesthesia, is very difficult to administer. There is a lack of direct visualization of the vocal cords, tongue fall following relaxation, and an already narrowed passage due to a small mandible, which makes even the blind nasal intubation difficult. There are various techniques described in literature to overcome these challenges, failing which, one needs to do tracheostomy. All the risks of difficult intubation and general anaesthesia can be avoided if the surgery is done under local anaesthesia. A simple but effective method of successful local anaesthesia is described, which allows successful temporomandibular joint reconstruction.

Abstract: Context: Surgery for the release of temporomandibular joint (TMJ) ankylosis is a commonly performed procedure. Various interposition materials have been tried with varying success rates. However, none of these procedures attempt to recreate the architecture of the joint as the glenoid surface is usually left raw. Aims: We aimed to use a vascularised cartilage flap and to line the raw surface of the bone to recreate the articular surface of the joint. Settings and Design: There is a rich blood supply in the region of the helical root, based on branches from the Superficial Temporal Artery (STA), which enables the harvest of vascularised cartilage from the helical root for use in the temporomandibular joint. Materials and Methods: Two cases, one adult and the other a child, of unilateral ankylosis were operated upon using this additional technique. The adult patient had a bony segment excised along with a vascularised cartilage flap for lining the glenoid. The child was managed with an interposition graft of costochondral cartilage following the release of the ankylosis, in addition to the vascularised cartilage flap for lining the glenoid. Results: The postoperative mouth opening was good in both the cases with significant reduction in pain. However, the long-term results of this procedure are yet to be ascertained. Conclusions: The vascularised cartilage flap as an additional interposition material in temporomandibular joint surgery enables early and painless mouth-opening with good short-term results. The potential applicability of this flap in various pathologies of the temporomandibular joint is enormous.

Indian Journal of Plastic Surgery , 2009,
Abstract: Temporomandibular 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.

Abstract: Background: The sequelae of temporomanibular joint (TMJ) ankylosis include limitationof jaw movement, interference of oral function and affects on the craniofacialgrowth. Analysis of the craniofacial form of TMJ ankylosis offers guidelinesfor managing this disease.Methods: Forty-five patients with intraarticular TMJ ankylosis were collected from thefiles at the Chang Gung Craniofacial Center. There were 21 male and 24female patients, aged 3 to 47 years. Thirty-seven patients were unilaterallyaffected and eight had bilateral involvement. Patients were grouped accordingto gender and age. Both the medical history and onset of the disease wereinvestigated in all patients. The pretreatment lateral cephalograms were usedfor analysis. The variables were compared with the Chinese norms with correspondingsex and age groups.Results: The etiology included 48.9% facial trauma history, 17.8% traumatic deliveryor birth injury, 15.6% middle ear or dental infection, 2.2% chronic arthritisand 15.6% unknown causes. The onset of mouth opening limitation wasunder 16 years of age. The average total mandibular length was less than thenorm by 30 mm. Each patient presented with a mandible that had backwardrotation with chin recession. Accentuated antegonial notch and inferiorlylocated condyle were observed on the affected side. The maxilla was shorterand the ANB was larger than the norm by 10° but the overbite and overjetwere within normal ranges.Conclusions: The facial growth was severely disturbed in terms of dimension, morphologyand direction of growth in patients with TMJ ankylosis. Better managementof mandibular fractures, good infection control and early treatment interventionare ways to reduce the influence on craniofacial growth.

Abstract: In temporomandibular joint (TMJ) ankylosis, direct laryngoscopy and intubation are not feasible. The scenario becomes more challenging in paediatric patients. The best technique would be fibreoptic bronchoscope (FOB) aided nasal intubation. We report successful nasal intubation with the aid of orally placed adult sized fibreoptic bronchoscope in a child with a limited mouth opening. A 6-yr-old child was brought with history of inability to open the mouth. Diagnosis of left sided TMJ ankylosis was made and interpositional arthoplasty was planned. Airway examination revealed interincisor gap of 4.6 mm. Due to tooth decay, a maximum mouth opening of 5.2 mm was observed on the left side. The airway was successfully secured through the nasal route aided by the adult sized bronchoscope inserted orally through the gap between the eroded upper and the lower teeth. Adult sized fibreoptic bronchoscope may be useful in aiding nasal intubation in pediatric patients if the mouth opening permits its introduction orally.
