“…The OAVS individuals can be classified as ‘unilateral’ when the craniofacial involvement is present only on one side, or ‘bilateral’, when both sides of the cranium are involved (in different magnitudes), even if it is only found a preauricular skin tag among individuals. However, most of the literature does not separate the sample according to the severity of the mandibular deformity 23,24 . It is also common to present the AS and US for the characterization of these individuals 24 and use the US as a control for measurement comparison.…”

It is also common to present the AS and US for the characterization of these individuals 24 and use the US as a control for measurement comparison. However, it was unsure, until now, whether the contralateral side of unilateral OAVS was in fact unaffected or just less affected, as there was no previous study with this statement.…”

Objectives The objectives of this study were to characterize the craniofacial and airway morphology of oculo‐auriculo‐vertebral spectrum (OAVS) individuals using computed tomography (CT) examination. Setting and Sample Population This sample included individuals in the age range from 5 to 14 years, consisted of a group of 18 OAVS individuals (12 females and 6 males), Pruzansky‐Kaban1 IIB and III and by a paired control group matched by age and sex for comparison of morphometric and airway variables. Materials and Methods Through the CT examination, airway analysis was performed using Dolphin Imaging® Software, and seven morphometric measurements were performed to evaluate craniofacial morphology by Materialize Mimics® Software. To compare airway and morphometric variables, the control group was used. Student's t test and Mann‐Whitney U test were performed to compare differences between the groups. Results Statistically significant differences were showed between the control and OAVS groups for the variables: total airway (TA) area, volume and MAA, RP area, RP volume, RP MAA, RG volume, RG MAA, total posterior height diff, Md incl and y‐axis asymmetry. Pearson and Spearman's correlation showed mostly moderate correlations between Mand Occlusal canting AS with TA area and RP volume, Ax‐Gn with TA area and Hy‐C3 with TA volume. Conclusions The OAVS's airway was altered and worse than the control group. Our results suggest that the contralateral side of OAVS individuals is unaffected; however, longitudinal assessments are needed to confirm it. Hyoid bone and postural measures play an important role in interpreting airway features of individuals with and without OAVS.

Oculo-auriculo-vertebral spectrum: new genes and literature review on a complex disease

et al. 2022

View full text Add to dashboard Cite

Oculo-auriculo-vertebral spectrum (OAVS) or Goldenhar syndrome is due to an abnormal development of first and second branchial arches derivatives during embryogenesis and is characterised by hemifacial microsomia associated with auricular, ocular and vertebral malformations. The clinical and genetic heterogeneity of this spectrum with incomplete penetrance and variable expressivity, render its molecular diagnosis difficult. Only a few recurrent CNVs and genes have been identified as causatives in this complex disorder so far. Prenatal environmental causal factors have also been hypothesised. However, most of the patients remain without aetiology. In this review, we aim at updating clinical diagnostic criteria and describing genetic and non-genetic aetiologies, animal models as well as novel diagnostic tools and surgical management, in order to help and improve clinical care and genetic counselling of these patients and their families.

“…Recently, a new three-dimensional imaging technique called cone beam computed tomography (CBCT) has proved to supply an excellent volumetric study of maxillofacial bone structures [10] and satisfactorily recognise mandibular fractures [11]. Moreover, it has a high spatial resolution (0.075-0.4 mm isotropic voxel) [12], delivers relatively low radiation doses compared to MSCT [13], and is only slightly affected by metal artefacts, which often occur in patients stabilised by immobilisation techniques that use metallic materials during post-treatment follow-up [14].…”

Imaging of mandibular fractures: a pictorial review

et al. 2020

Mandibular fractures are among the most common maxillofacial fractures observed in emergency rooms and are mainly caused by road accidents. The clinical features of mandibular fractures include malocclusion and loss of mandibular function. Panoramic radiography is usually limited to isolated lesions, whereas computed tomography is the tool of choice for all other facial traumatic events. No reference standard classification system for the different types of mandibular fractures is defined. Therapeutic options include a conservative approach or surgical treatment based on the anatomic area and the severity of fracture. The main purpose of this pictorial review is to illustrate a practical description of the pathophysiology of mandibular fractures and describe both the imaging techniques to recognise them and the therapeutic indications.
