Non-syndromal, true congenital ankylosis of the temporomandibular joint: A case of a six-week old boy with bilateral congenital fibrous intra-articular ankylosis of the temporomandibular joint is presented.

The literature is reviewed and limitations to management are highlighted. Ankylosis of the temporomandibular joint TMJ involves fusion of the mandibular condyle to the base of the skull 1. Occurrence in early childhood usually affects growth and the development of the jaws and teeth.

Occasionally, it may lead to upper airway obstruction and cor pulmonale 2. True congenital ankylosis of the TMJs is rare. In a review of cases of ankylosis of the TMJ, Topazian in documented only five cases. The case presented here, therefore, represents an additional case to the scanty literature. The baby was a spontaneous vaginal delivery at the maternity unit of the hospital complex in Zaria, Nigeria, after an uneventful full term pregnancy.

There was no evidence of obstetric trauma. Parents brought the baby to hospital due to the inability to open his mouth 22 hours post delivery. The birthweight at delivery was 3. The patient was the last of three siblings and there was no history of similar problems in the other siblings. Examination revealed a healthy looking boy with slight mandibular retrognathism Fig. There were some slight movement at the temporomandibular joints bilaterally when the patient was stimulated to cry.

However, inter-alveolar distance was limited to about 2 mm. No other abnormality was detected. Weight at presentation was 3. Laboratory investigations were within normal limits. The blood picture also showed anisocytosis, poikilocytosis, microcytosis and hypochromia. Electrolyte and urea levels were within normal limits. His genotype was AA.

Plain radiograph for the chest revealed no abnormality. A clinical and radiographic diagnosis of bilateral congenital fibrous intra-articular ankylosis was made.

However, the patient was subsequently lost to follow-up. True congenital ankylosis of the jaws is shrouded in controversy 15, 16 as some authors have associated it with obstetric trauma forceps delivery Vibrosa congenital ankylosis of the TMJ is immobility of the joint from birth in the absence of other likely causes of ankylosis such as birth trauma 5. There was no history of trauma during obstetrics.

Mouth opening gap between the upper and lower gum pads was limited to 2 mm when the patient was stimulated to cry Fig. In cases of post-obstetric trauma ankylosis, mouth opening reduces gradually in the neonatal period due to fibrosis.

Such cases on late recognition have been erroneously termed congenital ankylosis. The exact pathogenesis of congenital ankylosis is unknown.

The various proposed hypotheses include anomalous fusion of embryonal mesenchyme in early development during embryogenesis 4an abnormality of the stapedial artery in the fetus 12hypervitaminosis A 13 and early loss of neural crest cells Temporomandibular joint ankylosis, especially when it occurs in childhood, causes aesthetic defects in the face, malocclusion, inability to enjoy the culinary acts and malnutrition The index case had nutritional anaemia.

Increased upper airway resistance could result in cor pulmonale apart from the risk of asphyxia in transient upper airway obstruction. Hence early recognition and management are necessary. Nwoku and Kekere Ekun 4 reported the first case in Nigeria. This was a case of bony fusion between the coronoid process and the maxillary tuberosity in contrast to the case reported here, which is fibrous, bilateral and intra-articular. Hence this could be described as a congenital, bilateral, true, fibrous, intra-articular ankylosis of the temporomandibular joint.

The principal aids to diagnosis of ankylosis are clinical findings and radiology. The case from Lagos, Nigeria 4 had plain radiograph demonstrating the abnormal bony fusion. In the present case, CT scan showed isodense soft tissue shadows on both sides of the right joint capsule and on the medial aspect of the left joint capsule which obliterated the intra-articular cartilage hypodensity Figs.

The management of ankylosis has been described but the congenital forms are peculiar in their anaesthetic requirements and possibility of non-compliance to jaw opening exercises.

Adekeye et al 3 have observed the latter as a major cause of recurrence while the former could be responsible for mortality. The case presented here would have been operated on at the age of six months when anaesthetic difficulties would have been surmounted.
