- Background: Feeding and swallowing impairment are present in up to 80% of oculo-auriculo-vertebral spectrum (OAVS) patients. Salivary gland abnormalities have been reported in OAVS patients but their rate, features, and relationship with phenotype severity have yet to be defined.Material and methods: Parotid and submandibular salivary gland hypo/aplasia was evaluated on head MRI of 25 OAVS patients (16 with severe phenotype, Goldenhar syndrome) and 11 controls.Results: All controls disclosed normal salivary glands. Abnormal parotid glands were found exclusively ipsilateral to facial microsomia in 21/25 OAVS patients (84%, aplasia in six patients) and showed no association with phenotype severity (14/16 patients with Goldenhar phenotype vs 7/9 patients with milder phenotype, p = 0.6). Submandibular salivary gland hypoplasia was detected in six OAVS patients, all with concomitant ipsilateral severe involvement of the parotid gland (p < 0.001). Submandibular salivary gland hypoplasia was associated to Goldenhar phenotype (p < 0.05). Parotid gland abnormalities were associated with ipsilateral fifth (p < 0.001) and seventh cranial nerve (p = 0.001) abnormalities. No association was found between parotid gland anomaly and ipsilateral internal carotid artery, inner ear, brain, eye, or spine abnormalities (p > 0.6).Conclusions: Salivary gland abnormalities are strikingly common in OAVS. Their detection might help the management of OAVS-associated swallowing and feeding impairment.

- Introduction: Intracranial vascular, bone, and brain abnormalities might be observed in oculo-auriculo-vertebral spectrum (OAVS) patients even though these structures do not derive embryologically from the first and second pharyngeal arches. This neuroimaging study investigated their type, frequency and phenotype correlations among OAVS patients.Methods: Thirty-five OAVS patients (mean-age 4.8 ± 6.0 years; age range 0.3-30, 14 females) underwent head CT (all patients) and brain MRI (32 patients); 19 patients had a more severe phenotype (Goldenhar syndrome). Internal carotid artery hypoplasia/agenesia and abnormal course, brain abnormalities, internal acoustic canal stenosis/aplasia, cochlear-vestibular malformations, facial nerve bony canal anomalies, and oval window atresia were recorded.Results: Nine of 35 (26%) OAVS patients showed internal carotid artery anomalies; 18/32 (56%) had protean brain MRI abnormalities, ranging from tegmental cap anomaly to mild ventriculomegaly, which were associated with Goldenhar syndrome (p < 0.001) and concomitant cranial nerve abnormalities (p = 0.004); 11/35 (31%) disclosed cochlear-vestibular abnormalities including Michel deformity, common cavity, cochlear hypoplasia, and incomplete partition type-1 that were associated with Goldenhar syndrome (p = 0.01) and ipsilateral VIII cranial nerve abnormalities (p < 0.001); 16/35 (46%, 23 sides) presented facial nerve bony canal abnormalities that were associated with Goldenhar syndrome (p < 0.001) and ipsilateral VII cranial nerve (p < 0.001) and cochlear-vestibular (p < 0.001) abnormalities; and 23/31 (74%, 31 sides) showed oval window atresia, always with concomitant ossicular chain dysplasia.Conclusions: Intracranial vascular, bone, and brain abnormalities in OAVS patients are strikingly common and heterogeneous. As their detection might impact significantly on clinical and surgical management of affected patients, accurate neuroimaging investigations should be included in the diagnostic work-up of OAVS.
