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 ...
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 hallmark of a masticatory space infection is trismus or infection in anterior compartment of lateral pharyngeal space results in trismus. If these infections are unchecked, can spread to various facial spaces of the head and neck and lead to serious complications such as cervical cellulitis or mediastinitis.
The communications of each pterygomandibular space are: [1] to the buccal space anteriorly; to the lateral pharyngeal space and peritonsillar space medially (around the medial pterygoid muscle). to the submasseteric space laterally (around the ramus of the mandible) to the parotid space posteriorly; to the deep temporal/infratemporal space ...
This is also referred to as the masseter space or the superifical masticator space. The submasseteric space is logically located under (deep to) the masseter muscle, created by the insertions of masseter onto the lateral surface of the mandibular ramus. Submasseteric abscesses are rare and are associated with marked trismus.
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 .
Behind the ostium of the eustachian tube (ostium pharyngeum tuba auditiva) is a deep recess, the pharyngeal recess (fossa of Rosenmüller). Clinical significance [ edit ]
The boundaries of the infratemporal space are: [4] the greater wing of the sphenoid bone superiorly; the pterygomandibular space inferiorly; the infra-temporal surface of the maxilla anteriorly, the lateral pterygoid plate, part of the lateral pterygoid muscle and lateral pharyngeal wall medially
