A parapharyngeal abscess is a deep neck space abscess of the parapharyngeal space (or pharyngomaxillary space), which is lateral to the superior pharyngeal constrictor muscle and medial to the masseter muscle. [1] This space is divided by the styloid process into anterior and posterior compartments.
The parapharyngeal space (also termed the lateral pharyngeal space), is a potential space in the head and the neck. It has clinical importance in otolaryngology due to parapharyngeal space tumours and parapharyngeal abscess developing in this area. It is also a key anatomic landmark for localizing disease processes in the surrounding spaces of ...
The prevertebral space is a space in the neck. On one side it is bounded by the prevertebral fascia. [1] On the other side, some sources define it as bounded by the vertebral bodies, [2] and others define it as bounded by the longus colli. [1]
The retropharyngeal space (abbreviated as "RPS" [1] [2]) is a potential space [2] [3] and deep compartment of the head and neck [1] situated posterior to the pharynx. [4] The RPS is bounded anteriorly by the buccopharyngeal fascia, posteriorly by the alar fascia, and laterally by the carotid sheath.
The deep temporal space is a fascial space of the head and neck (sometimes also termed fascial spaces or tissue spaces). It is a potential space in the side of the head, and is paired on either side. It is located deep to the temporalis muscle. The inferior portion of the deep temporal space is also termed the infratemporal space.
The danger space or alar space, is a region of the neck. [1] The common name originates from the risk that an infection in this space can spread directly to the thorax , and, due to being a space continuous on the left and right, can furthermore allow infection to spread easily to either side.
The superficial temporal and the deep temporal spaces are sometimes together called the temporal spaces. The masticator spaces are paired structures on either side of the head. The muscles of mastication are enclosed in a layer of fascia, formed by cervical fascia ascending from the neck which divides at the inferior border of the mandible to ...
Retropharyngeal abscess (RPA) is an abscess located in the tissues in the back of the throat behind the posterior pharyngeal wall (the retropharyngeal space).Because RPAs typically occur in deep tissue, they are difficult to diagnose by physical examination alone.
