Spaces Flashcards
Where is the Vestibular Space?
Deep to buccinator and superficial to the oral mucosa.
What is the buccal space?
This lies superficial to the buccopharyngeal fascia covering buccinator. It’s posterior bored is the pterygomandibular raphe.
Which spaces is the buccal space in communication with?
Temporal
Pterygomandibular
Lateral Pterygoid
Masticator
Where is the pterygomandibular space located?
Between medial pterygoid and the mandible
Suggest one clinical procedure which can introduce infection into the pterygomandibular space.
Inferior alveolar nerve block.
What are the subspaces of the masticator space?
Temporal
Infratemporal fossa
Pterygomandibular space
which structures is the lateral pharyngeal space surrounded by?
Carotid sheath
Alar layer of prevertebral fascial
Buccopharyngeal fascia
What is the danger space?
This is a space between the alar and deep layers of prevertebral fascia which extends down as far as the diaphragm.
What is the inferior extent of the retropharyngeal space?
T2-4 where fusion of the buccopharyngeal and alar layer of prevertebral fascia takes place.
What is the prevertebral space? What is the consequence of infection here?
This lies between the vertebrae and the deep layer of prevertebral fascia.
Infection here can result in collapse of vertebrae.
Name the spaces surrounding mylohyoid.
Superior - sublingual
Inferior - submandibular
What is Ludwig’s angina?
This is a rapidly spreading infection of the submandibular and/or sublingual spaces. This can cause mortality by asphyxiation.
