4. Surgical anatomy of the areas and spaces in the maxillofacial area Flashcards
1
Q
Fascial spaces
A
- Aka fascial tissue spaces or tissue spaces
- Potential spaces that exist between the fasciae and underlying organs and other tissues
- In healthy conditions=> do not exist
- Created by pathological conditions such as the spread of pus or cellulitis in an infection.
2
Q
How fascial spaces differ from fasciae
A
- Fascial spaces are potential spaces that can form between tissues during infections
- Fasciae are bands of connective tissue that surround and support structures like muscles
3
Q
What facilitates the opening of fascial spaces
A
- Pathogenic bacterial release of enzymes=>
- Hyaluronidase and collagenase, which cause tissue lysis
4
Q
Clefts in the context of fascial spaces
A
Fascial spaces filled with loose areolar connective tissue
5
Q
What fascial spaces may contain based on their location
A
- Salivary glands, blood vessels, nerves, and lymph nodes
- Spaces containing neurovascular tissues (nerves and blood vessels) also be termed compartments.
6
Q
How fascial spaces are classified in oral and maxillofacial surgery
A
- Primary maxillary spaces
- Primary mandibular spaces
- Perimandibular spaces
7
Q
The primary maxillary spaces
A
- Canine space
- Buccal space
- Infratemporal space
8
Q
The primary mandibular spaces
A
- Submental space
- Buccal space
- Submandibular space
- Sublingual space
- Submasseteric space
9
Q
The perimandibular spaces
A
- Submandibular space
- Submental space
- Sublingual space
- Mental space
- Buccal space
- Canine space (infra-orbital space)
- Submasseteric space
- Pterygomandibular space
- Infratemporal space
10
Q
Submandibular space
A
- Potential space, paired on either side
- Located on the superficial surface of the mylohyoid muscle=>
- Between the anterior and posterior bellies of the digastric muscle.
11
Q
Sublingual space
A
- Potential space located below the mouth and above the mylohyoid muscle
- Part of the suprahyoid group of fascial spaces
12
Q
Submental space
A
- Potential space located between the mylohyoid muscle superiorly and the platysma muscle inferiorly=>
- Under the chin in the midline
13
Q
Canine space (infra-orbital space)
A
- Aka the infra-orbital space
- Thin potential space on the face, paired on either side
- Located between the levator anguli oris muscle inferiorly and the levator labii superioris muscle superiorly
- infections from the maxillary canine tooth may spread to this space
14
Q
Mental space
A
- Potential space, bilaterally located in the chin=>
- Between the mentalis muscle superiorly and the platysma muscle inferiorly
15
Q
Submasseteric space
A
- Potential space over the angle of the jaw, paired on each side
- Located between the lateral aspect of the mandible and the medial aspect of the masseter muscle and its investing fascia
