INTRODUCTION
We discuss our findings on the retention of the medially displaced residual condyle during the treatment of type III temporomandibular joint ankylosis, as well as the postoperative results observed during follow-up.
MATERIALS AND METHODS
Thirty-two patients with type III temporomandibular joint ankylosis that met the inclusion criteria of the study were included as subjects. The morphological integrity of the medially displaced residual condyle was verified in all of the participating patients through the use of cone beam computed tomography. The duration of the ankylosis ranged from 2 to 12 years. The maximum length that patients were able to open their mouths ranged from 6 mm to 14 mm. The surgical treatments used in this report included the separation of bony fusions between the condyle and the glenoid fossa, resection of the ankylosed sites, preservation of the displaced condyles in their medial position and suturing the remains of the disc to its typical position or taking the temporalis myofascial flap instead. The long-term results were evaluated by computed tomography and clinical follow-up examinations.
RESULTS
Three-year postoperative follow-up examinations were performed for all of the patients included in this study. No recurrences were observed in the patients who adhered to the postoperative therapeutic advice. Patients had an average maximal mouth opening distance of 34.50 ± 5.75 mm as recorded during the final follow-up examination.
CONCLUSIONS
The released medially residual condyle can still function normally in temporomandibular joint movement and without reankylosis after a bone fusion resection. The displaced condyle should thus be preserved instead of being removed during the treatment of type III temporomandibular joint ankylosis.

The purpose of this experiment was to investigate whether low-intensity pulsed ultrasound (LIPUS) irradiation can inhibit dentoalveolar ankylosis in transplanted rat teeth. LIPUS irradiation (the pulsed ultrasound signal had a frequency of 3.0 MHz, a spatial average intensity of 30 mW/cm, and a pulse ratio of 1:4) was performed on the face over the re-planted teeth of rats for 4 weeks. After the rats were euthanized, we measured mobility (Periotest value [PTV]) of the transplanted and control teeth using a Periotest. Finally, we performed histological evaluation to detect ankylosis. PTVs tended to be significantly lower for re-planted teeth than for control teeth. Histological evaluation revealed that the roots of all re-planted teeth were coalescent with alveolar bone. Furthermore, no ankylosis was observed in three-fifths of the re-planted teeth following LIPUS irradiation. These results indicate the potential efficacy of LIPUS to inhibit dentoalveolar ankylosis.

Comparative Study
OBJECTIVES
To compare the pre-operative clinical and radiographic findings of temporomandibular joint (TMJ) ankylosis with those found at operation and propose new classification.
METHODS
Thirty-three patients were treated for TMJ ankylosis. There were 18 unilateral and 12 bilateral cases. All patients underwent pre-operative clinical and radiographic examination, (consisting of a panoramic radiograph, axial and coronal CT. The surgical findings were compared with the imaging features.
RESULTS
Post-contrast coronal CT was the best imaging modality for planning surgery as it displayed the anatomical relationship between the ankylosed segment and the surrounding vital structures, particularly where the sphenoid and temporal bones were involved.
CONCLUSIONS
Surgical planning should be based on coronal and axial CT. A new classification of TMJ ankylosis based on the CT findings is proposed.

The treatment of temporomandibular joint ankylosis requires excision of the involved structures and immediate reconstruction. This paper presents a consecutive series of nine pediatric patients (mean age 7.7 years) who underwent a standardized treatment protocol to 13 affected joints. Four patients had unilateral temporomandibular joint ankylosis, five bilateral. One child required bilateral release but only unilateral reconstruction. Radiographic evidence demonstrated bony ankylosis in a total of 13 joints. Two patients had undergone surgical intervention of the temporomandibular joint before presentation to the authors. Two patients had preoperative temporomandibular joint pain. The cause of ankylosis was primarily traumatic or congenital. Our operative protocol included excision of the involved ankylotic structures through a coronal and Risdon incision, followed by immediate costochondral grafting. Fixation with miniplates and screws allowed for early mobilization. For unilateral patients, maximal incisal opening was improved from 5.4 mm before surgery to 24.8 mm after it, and for bilateral patients, from 6.0 to 17.5 mm. Mean follow-up was 2 years; only one patient was followed for less than 1 year. Pain symptoms were relieved after surgery. Perioperative complications were minimal, with no evidence of infection, facial nerve injuries, or bleeding. Patients with unilateral or bilateral ankylosis of traumatic cause achieved satisfactory functional results after surgery, while those in our bilateral congenital patients were far more limited. Rationales for this divergence in results are presented.

A report of congenital ankylosis of the temporo-mandibular joint has only very rarely been published. The existence of this entity has been met with great scepticism and therefore believed to be due to perinatal trauma and subsequent development of the ankylosis. However, publications are now available of observations at birth after an uneventful pregnancy and spontaneous delivery. Our cases are the first publication of congenital TMJ ankylosis in two siblings, although there are hints in the histories in two other papers that a sibling may have suffered from the same condition. We discuss the hypothesis that the potential to ankylose in the temporomandibular area is a congenital disorder as in our cases, and that even later in life trauma or infection are only supervening initiating factors.

Longstanding unilateral temporomandibular joint ankylosis, which starts during the active growth period in early childhood, results in facial asymmetry. Three problems are encountered: the ankylosed joint; the asymmetric face and, occasionally, upper airway obstruction. Simultaneous surgery was performed on 27 patients to release the joint ankylosis and to correct the facial deformity. Bimaxillary surgery was done for adult patients with occlusal canting, and mandibular surgery alone for adult patients without occlusal canting and for young children. Very satisfactory results were obtained during a follow-up period ranging from 2 to 6 years, regarding the restoration of joint function, improvement in aesthetic appearance and relief of respiratory obstruction.

The predominant aetiology in 24 cases of temporomandibular ankylosis treated surgically since 1976 was trauma. Among the patients operated upon for post-traumatic ankylosis one anatomoclinical form could be identified characterized by an external block attaching the condylar neck to the zygomatic bone, and an internal joint by movement of the head or part of the condylar head. A favorable prognosis can be given in this type of lesion as resection of the block does not modify the height of the ascending ramus.

Twenty-three cases of acute spinal cord injury in persons with cervical ankylosis are presented. Certain characteristics of major sub-groups are described: ankylosing spondylitis (N = 8), degenerative spondylosis (N = 9) and congenital fusion (congenital non-segmentation) (N = 6). The ankylosing spondylitic group presented a grim prognosis for survival (death rate 50 per cent within 60 days) and for loss of neurological function. Five out of eight cases had permanent neurological loss subsequent to their injuries. Both the ankylosing spondylitic and degenerative spondylotic groups presented problems in diagnosis and medical management. The basic principle is immobilisation of the fracture and mobilisation of the patient. The halo is the technique of choice for fracture immobilisation. An integrated intensive respiratory management programme is essential. Patients with ankylosed spines, particularly those with ankylosing spondylitis, should be educated in simple measures to prevent fracture of their spines.
