Case of oculo-auriculo-vertebral spectrum: rare clinical features.

ABSTRACT: A 2-month-old boy presented to us with bilateral microtia, left lower motor neuron facial palsy, micrognathia, hemivertebra, bifid rib, bifid thumb and absent/hypoplastic right-sided depressor anguli oris. He had bilateral external auditory canal atresia, although response to loud sound was present. Brain stem evoked response audiometry (BERA) was advised at 3 months of age. Karyotype was normal. We diagnosed him as a case of oculo-auriculo-vertebral spectrum. Child was discharged on request by the family with the plan for bone-anchored hearing aid after BERA and plan for pinna and ear canal reconstruction at a later age but child did not come for any follow-up visit. On telephonic enquiry, it was found that he is thriving well but has developmental delay including speech delay. We conclude that children presenting with external ear abnormalities should be screened for multiple congenital anomalies so that a multidisciplinary approach to management can be planned.

Project description:Background and purposeCranial nerve abnormalities might be observed in hemifacial microsomia and microtia (oculo-auriculo-vertebral spectrum), but the rate, features, and relationship with functional impairment or phenotype severity have not yet been defined. This study aimed at investigating absence/asymmetry, abnormal origin, morphology and course of cranial nerves, and presence/asymmetry of the foramen ovale and inferior alveolar nerve canal in a cohort of oculo-auriculo-vertebral spectrum patients.Materials and methodsTwenty-nine patients with oculo-auriculo-vertebral spectrum (mean age, 7 years; age range, 0.2-31 years; 12 females) underwent brain MR imaging, CT, and neurologic evaluation; 19 patients had a more severe phenotype (Goldenhar syndrome).ResultsCranial nerve abnormalities were detected only in patients with Goldenhar syndrome (17/19, bilaterally in 8) and were involved the second (4/19), third (1/18), fifth (11/19), sixth (8/16), seventh (11/18), and eighth (8/18) cranial nerves. Multiple cranial nerve abnormalities were common (11/17). Eleven patients showed bone foramina abnormalities. Trigeminal and facial nerve dysfunctions were common (44% and 58%, respectively), especially in patients with Goldenhar syndrome. Trigeminal abnormalities showed a good correlation with ipsilateral dysfunction (P = .018), which further increased when bone foramina abnormalities were included. The facial nerve showed a trend toward correlation with ipsilateral dysfunction (P = .081). Diplopia was found only in patients with Goldenhar syndrome and was associated with third and sixth cranial nerve abnormalities (P = .006).ConclusionsAmong patients with oculo-auriculo-vertebral spectrum, cranial nerve morphologic abnormalities are common, correlate with phenotype severity, and often entail a functional impairment. The spectrum of cranial nerve abnormalities appears wider than simple hypo-/aplasia and includes an anomalous cisternal course and partial/complete fusion of diverse cranial nerves.
