Bilateral incyclotorsion,absent facial nerve,and anotia: Fellow travelers in Möbius sequence or oculoauriculovertebral spectrum?

We report a patient with bilateral incyclotorsion, asymmetric facial palsy, monocular depression deficiency, and unilateral Type 3 Duane syndrome, along with contralateral anotia and a midline cleft palate. A dysplastic middle ear cavity and unilateral absence of the facial nerve were noted on magnetic resonance imaging scanning. The differential diagnosis includes M?bius sequence, oculoauriculovertebral spectrum, and a congenital cranial dysinnervation disorder.
