TERMINOLOGY

  • Abbreviations

    • Parapharyngeal space (PPS)

  • Synonyms

    • Some authors define PPS more broadly, separating it into prestyloid and poststyloid components
    • In this text, PPS preferred over prestyloid PPS and carotid space (CS) over poststyloid PPS

  • Definitions

    • PPS: Central, fat-filled space in lateral suprahyoid neck (SHN) around which most of important spaces are located
      • These surrounding important spaces are pharyngeal mucosal space (PMS), masticator space (MS), parotid space (PS), and CS
