Spatium Massetericomandibulare and Perimandibular Abscess

From WikiLectures

Spatium Massetericomandibulare[edit | edit source]

  • Also called submasseteric or masseteric space
  • It is a potential space (under normal- healthy conditions it does not exist)

Borders[edit | edit source]

  • Inferior: Insertion of masseter muscle (masseteric tuberosity)
  • Posterior: Parotid gland (parotid fascia)
  • Lateral: Masseter muscle
  • Medial: Ramus of mandible
  • Anterior: continuous with buccal region

Clinical Notes[edit | edit source]

  • This space is involved when periapical abscess, usually from the lower wisdow teeth, continues and spreads in this location
  • The abscess in spatium massetericomandibulare causes significant trismus (inability to open the mouth)

Perimandibular Abscess[edit | edit source]

  • Accumulation of pus laterally and medially from the mandibular body
  • Usually infection originates from the mandibular molars
  • Occurs in perimandibular spaces
  • Perimandibular spaces:
  1. Spatium peritonsilare
  2. Spatium paratonsilare
  3. Spatium pterygomandibulare
  4. Spatium massetericomandibulare
  5. Spatium sublingualis
  6. Spatium submandibulare
