Deep/superficial temporal
Describe the vestibular space?
From the cortical alveolar bone to the mucoperiosteum. It is the most common infection space.
Describe the canine space?
From the levator anguli oris to the levator labii superioris, sits superficial to the canine fossa, and usually caused by canine or incisor infection
Describe the buccal space?
Between the buccinator and the skin, this is where the buccal fat pad lies, usually infection due to infections from the premolars or molars
Describe the sublingual space?
Space from below the tongue to the mylohyoid, usually infected from teeth (incisors, canine, premolars, molars) that are above the mylohyoid line
Describe the submental spcae?
From below the chin to the anterior belly of digastric, infection usually from the lower incisors
Describe the submandibular spcae?
Forms the submandibular triangle below the mylohyoid line, infection from usually the 2nd or 3rd molar whose roots are below the mylohyoid line.
What is Ludwig’s angina?
Infection of all the perimandibular spaces (sublingual, mental, and mandibular), causes bilateral swelling of the chin and neck. It causes the tongue to be displaced up and back, blocking the airways.
Describe the superficial and deep temporal space?
Infection that presents as a lateral hourglass swelling and usually from the 2nd or 3rd upper molar
Describe the masseteric space?
Space that lies between the masseter and ramus, infection usually involves trismus, and usually involves an impacted 3rd molar.
