Parapharyngeal Space
It is classed as one of the suprahyoid fascial spaces because it is situated on the lateral aspect of the pharynx and is continuous with the retropharyngeal space posteriorly and the submandibular space anteriorly.
Parapharyngeal space. It is an inverted cone shaped potential space that extends from the hyoid bone to the base of the skull. Salivary gland neoplasms benign to malignant ratio 3 1. It consists largely of fat neurovascular structures and in some definitions the retromandibular part of the deep lobe of the parotid gland.
The parapharyngeal space also known as the prestyloid parapharyngeal space is a deep compartment of the head and neck around which most other suprahyoid fascial spaces are arranged. The direction of its displacement indirectly reflects the site of origin for masses or infection in adjacent areas and consequently their appropriate differential diagnosis. Second most common mostly in the poststyloid space.
Majority of parapharyngeal space tumor mostly in the prestyloid space. It has an inverted teepee shape. It has clinical importance in otolaryngology due to parapharyngeal space tumours and parapharyngeal abscess developing in this area.
The parapharyngeal space this fascial space is also known as the lateral pharyngeal space. The pps is shaped like an inverted pyramid extending from the skull base superiorly to the greater cornu of the. Parapharyngeal space tumors are rare and account for 0 5 of head and neck tumors 80 benign and 20 malignant.
The vast majority of these tumors are benign. The parapharyngeal space or lateral pharyngeal or pharyngomaxillary space is in the upper neck above the hyoid bone. The parapharyngeal space is a potential space in the head and the neck.
The parapharyngeal space pps is a potential space lateral to the upper pharynx. The parapharyngeal space pps is a potential space between the skull base above and the hyoid bone below. The parapharyngeal pharyngomaxillary space is lateral to the superior pharyngeal constrictor and medial to the pterygoid muscle.
