Study Notes

Abscesses and Their Classifications

Abscess types at low severity: Abscess of base of upper lip, Subperiosteal abscess, Vestibular abscess, Intraalveolar abscess of maxilla and mandible, Infraorbital abscess, Buccal abscess.
Cellulitis characterized as painful swelling of soft tissue in the mouth and face, resulting from the diffusion of purulent exudate.
Causes of cellulitis primarily linked to acute apical infections.

Displacement Classifications

Categories of bone displacement include:
- Inward and downward displacement of the Zygomatic Mask (ZM).
- Inward and posterior displacement of Zygomatic Complex (ZMC).
- Outward displacement of the zygomatic complex.
- Comminution of the whole zygomatic complex.

Spread of Infection

Pus may spread through;
- Continuity via tissue spaces and anatomical planes.
- Lymphatic system involvement.
- Blood circulation.

Symptoms and Signs of Cellulitis

Local signs include pain, swelling, surface erythema, pus formation, and limitation of motion.
Systemic signs consist of fever, malaise, lymphadenopathy, and elevated white blood cell count.
Specific symptoms exclude bleeding while emphasizing redness, tenderness, and warmth.

Severity Classifications of Cellulitis

Cellulitis severity levels: low severity, medium severity, and high severity.
High severity categories include diffuse cellulitis, Ludwig’s angina, and various abscesses like lateral pharyngeal and retropharyngeal.

Management and Treatment of Odontogenic Infections

Management goals focus on incision and drainage of the infection.
Localized odontogenic infection types include periapical, periodontal, and pericoronal infections.

Fascial Planes in Infection Spread

Fascial planes provide pathways for infection to travel from superficial to deep tissues, including gingiva, palatal abscess, maxillary sinus, maxilla, mandible, and floor of the mouth.

Miscellaneous Points

Abscesses with high severity context, such as submandibular abscess, are exceptions within low severity classifications.
Critical understanding of different types of localized infections allows for effective clinical management.
