Acute cellulitis is a purulent, infectious inflammation of the proto-connective tissue that occurs between the muscles around the jaw, between the muscles and the jawbone, and in areas such as the fascial subcutaneous area. It often occurs acutely, diffusely, and acutely diffusely, and is referred to as acute cellulitis. Cellulitis is all secondary to infection, mostly of odontogenic and glandular origin, and spreads with acute pericoronitis and lymphadenitis. The main symptoms of acute cellulitis are the manifestations of acute inflammation, with redness, swelling, heat, pain, and functional limitation as typical symptoms. The diagnosis of acute cellulitis is usually based on the pathogenic factors, clinical manifestations, and laboratory tests to confirm the occurrence of acute cellulitis.
