PATHOLOGY

Detailed explanation-1: -Lateral (buccal side) extension of an infected molar produces marked lateral facial swelling (buccal space), while involvement of canines (canine space) produces anterior mid-facial edema, which may extend to the periorbital space. Extension to the angle of the jaw (parotid space) may be confused with parotitis.

Detailed explanation-2: -(Ludwig Angina) Submandibular space infection is acute cellulitis of the soft tissues below the mouth. Symptoms include pain, dysphagia, and potentially fatal airway obstruction. Diagnosis usually is clinical. Treatment includes airway management, surgical drainage, and IV antibiotics.

Detailed explanation-3: -If not treated promptly, life-threatening complications, however, can occur: respiratory obstruction, pneumonia, descending mediastinitis, septic shock, sepsis, necrotizing fasciitis, pericarditis, cavernous sinus thrombosis, and brain abscesses.
