Summary
Oculoauriculovertebral spectrum (OAVS) patients may have craniocervical instability, but this study found no significant link with spinal malformations. Further research is needed to predict OAVS-related instability.
Area of Science:
- Medical Genetics
- Orthopedics
- Radiology
Background:
- Oculoauriculovertebral spectrum (OAVS) involves anomalies of the first and second pharyngeal arches, leading to craniofacial and spinal changes.
- Craniocervical junction instability is a potential complication of OAVS, posing risks during spinal manipulation.
- Limited research exists on the correlation between OAVS and craniocervical instability.
Purpose of the Study:
- To radiographically correlate OAVS patients with craniocervical instability.
- To investigate the prediction of craniocervical instability occurrence in OAVS.
- To assess the relationship between OAVS phenotype (OMENS score) and instability.
Main Methods:
- Radiographic assessment of cervical spine vertebral malformations and craniocervical instability.
- Clinical evaluation using the OMENS score by a multidisciplinary team.
- Statistical analysis including Student's t test, Kolmogorov-Smirnova, and Chi-squared tests.
Main Results:
- Seven out of 26 (26.9%) OAVS patients exhibited craniocervical instability.
- Patients with instability had higher OMENS scores, though not statistically significant.
- Spinal malformations were present in all patients with instability and 57.8% without; scoliosis was most common.
- No statistical significance was found between spinal malformations and craniocervical instability.
- Extracraniofacial findings, particularly radial anomalies, were noted in all patients with instability.
Conclusions:
- Higher OMENS scores showed a trend towards increased craniocervical instability in OAVS, but lacked statistical significance.
- The study did not find a statistically relevant association between the presence of spinal malformations and craniocervical instability in OAVS patients.

01:28Articulations of the Vertebral Column
2.0K
In addition to being held together by the intervertebral discs, adjacent vertebrae also articulate with each other at synovial joints formed between the superior and inferior articular processes called zygapophysial joints (facet joints). These are plane joints that provide for only limited motions between the vertebrae. The orientation of the articular processes at these joints varies in different regions of the vertebral column and serves to determine the types of motions available in each...

01:14Cranial Bones: Superior and Posterior View
2.5K
The superior view of the cranium shows the frontal and paired parietal bones.
The frontal bone is the single bone that forms the forehead. At its anterior midline, between the eyebrows, there is a slight depression called the glabella. The frontal bone also forms the supraorbital margin of the orbit. Near the middle of this margin is the supraorbital foramen, the opening that provides passage for a sensory nerve to the forehead. The frontal bone is thickened just above each supraorbital margin,...

01:27Cranial Bones: Lateral View
2.4K
The lateral view of the cranium is dominated by temporal, sphenoid, and ethmoid bones.
The temporal bone forms the lower lateral side of the skull. The temporal bone is subdivided into several regions. The flattened upper portion is the squamous portion of the temporal bone. Below this area and projecting anteriorly is the zygomatic process of the temporal bone, which forms the posterior portion of the zygomatic arch. Posteriorly is the mastoid portion of the temporal bone. Projecting...

01:19Cranial and Spinal Meninges
1.6K
The cranial and spinal meninges are complex protective structures surrounding the central nervous system (CNS), consisting of the brain and spinal cord. These meninges consist of the dura mater, the arachnoid mater, and the pia mater. They protect the CNS, provide structural support, and aid in circulating cerebrospinal fluid (CSF).
Cranial Meninges
These meningeal layers cover the cranium. The dura mater is the outermost layer of cranial meninges. It is a thick and durable membrane of dense...

01:29The Vestibular System
39.9K
The vestibular system is a set of inner ear structures that provide a sense of balance and spatial orientation. This system is comprised of structures within the labyrinth of the inner ear, including the cochlea and two otolith organs—the utricle and saccule. The labyrinth also contains three semicircular canals—superior, posterior, and horizontal—that are oriented on different planes.

01:22Sutures of the Skull
7.2K
The human skull is composed of several bones that come together to protect the brain and support the structures of the face. The junctions where these bones meet are called sutures.
Sutures are immobile joints between adjacent bones of the skull. The narrow gap between the bones is filled with dense, fibrous connective tissue that unites the bones. The long sutures located between the skull bones are not straight but instead follow irregular, tightly twisting paths. These twisting lines tightly...
