It includes the prevertebral muscles (longus colli and longus capitis), vertebral artery, vertebral vein, scalene muscles, phrenic nerve and part of the brachial plexus. [ 3 ] In trauma, an increased thickness of the prevertebral space is a sign of injury, and can be measured with medical imaging .
A computed tomography (CT) scan is the definitive diagnostic imaging test. [4] X-ray of the neck often (80% of the time) shows swelling of the retropharyngeal space in affected individuals. If the retropharyngeal space is more than half of the size of the C2 vertebra, it may indicate retropharyngeal abscess. [5]
It is bounded at the top by the skull base, at the front by the alar fascia and behind by the prevertebral fascia. It comes to an end at the level of the diaphragm. The retropharyngeal space is found anterior to the danger space, between the alar fascia and buccopharyngeal fascia. There exists a midline raphe in this space so some infections of ...
It is attached to the prevertebral fascia by loose connective tissue, with the retropharyngeal space found between them. [citation needed] It may also be attached to the alar fascia posteriorly at C3 and C6 levels. [5]
Mucous membrane shows thickening. [2] Air-fluid level may be observed if the radiograph is taken in "head-up" position. [2] It is not seen in radiograph taken in lying down position. The concavity of fluid opacity points upwards. Polyp: Maxillary sinus shows radiopacity; which is present despite the position in which the radiograph is taken.
The initial plain chest radiograph is almost always abnormal in patients with Boerhaave syndrome and usually reveals mediastinal or free peritoneal air as the initial radiologic manifestation. With cervical esophageal perforations, plain films of the neck show air in the soft tissues of the prevertebral space. [citation needed]
The celiac ganglion is part of the sympathetic prevertebral chain possessing a great variety of specific receptors and neurotransmitters such as catecholamines, neuropeptides, and nitric oxide and constitutes a modulation center in the pathway of the afferent and efferent fibers between the central nervous system and the ovary.
Eagle syndrome (also termed stylohyoid syndrome, [1] styloid syndrome, [2] stylalgia, [3] styloid-stylohyoid syndrome, [2] or styloid–carotid artery syndrome) [4] is an uncommon condition commonly characterized but not limited to sudden, sharp nerve-like pain in the jaw bone and joint, back of the throat, and base of the tongue, triggered by swallowing, moving the jaw, or turning the neck.
