More than meets the smile: facial muscle expression in children with Ochoa syndrome.

The Ochoa syndrome is the association of a non-neurogenic neurogenic bladder with abnormal facial muscle expression. Patients are at risk for renal failure due to obstructive uropathy. We report a family of three siblings, with an emphasis on the abnormalities in facial expression. Careful examination shows an unusual co-contraction of the orbicularis oculi and orbicularis oris muscles only when full facial expressions are exhibited, across a range of emotional or voluntary situations. This suggests a peripheral disorder in facial muscle control. Two thirds of patients have anal sphincter abnormalities. Aberrant organisation of the facial motor and urinary-anal sphincter nuclei may explain these symptoms.
