Question

Costochondral graft to a child aged 8 years after treatment: why does the mouth deviate to the unoperated site while opening?

• A. Unilateral condylar growth
• B. Malposition of the graft
• C. Neuromuscular imbalance
• D. Abnormal growth of the temporomandibular joint

Hint:

When performing costochondral grafts in children, closely monitor the growth of the condyle to prevent asymmetric jaw movements and functional deviations.

Answer 1

The Correct Option is A

After a costochondral graft is placed in a growing child, asymmetrical growth of the condyle can occur, leading to deviation of the mouth towards the unoperated side. The condylar growth on the grafted side may not match the natural growth on the unoperated side, resulting in a functional deviation.
