In the head and neck, potential spaces are primarily defined by the complex attachment of muscles, especially mylohyoid, buccinator, masseter, medial pterygoid, superior constrictor and orbicularis oris. [6] Infections involving fascial spaces of the head and neck may give varying signs and symptoms depending upon the spaces involved.
The danger space serves as an important pathway for complicated infections of the posterior pharynx to enter the chest and spinal column. Anterior to the parapharyngeal space is the masticator space which contains the lower dental row, muscles of mastication, the inferior alveolar nerve as well as branches of cranial nerve V .
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.
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.
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.
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.
PTA usually arises as a complication of an untreated or partially treated episode of acute tonsillitis. The infection, in these cases, spreads to the peritonsillar area (peritonsillitis). This region comprises loose connective tissue and is hence susceptible to formation of an abscess. PTA can also occur de novo. Both aerobic and anaerobic ...
This space may be created by pathology, such as the spread of pus in an infection, e.g. odontogenic infections. A periapical abscess may spread into the sublingual space if the apex of the tooth is above the level of attachment of mylohyoid, and the infection erodes through the lingual cortical plate of the mandible.
