We present the case of a patient, aged 4 years and 10 months, with metatropic dysplasia. The baby had repeated apnoeic episodes, bradycardia and cardiac arrests and was diagnosed with foramen magnum stenosis and atlantodental dislocation. The episodes were markedly associated with neck movements. Considering this clinical presentation, we performed laminectomy of the atlas, foramen magnum enlargement and decompression followed by dorsal C0-C2 stabilisation with allogeneic bone chips. After the operation, apnoeic episodes did not recur.

Keywords: metatropic dysplasia, atlantodental dislocation, apnoea, decompression
