A42.2
Cervicofacial actinomycosis
Clinical Classification Guidelines
Medical Intelligence & Overview
Cervicofacial actinomycosis is a rare bacterial infection involving the tissues of the face and neck. It is caused by the bacteria *Actinomyces israelii* and often occurs when these bacteria invade areas of the mouth or skin that have been injured or infected. This condition can lead to persistent swelling, abscesses, and the formation of hard lumps in the affected regions, making early identification and treatment important for recovery.
Causes & Symptoms
Clinical Causes: Oral trauma or injury, such as dental procedures, trauma, or surgeries Poor dental hygiene leading to infections in the mouth and jaw Spread from other infections in the head and neck areas Immunocompromised states, such as HIV/AIDS or diabetes Chronic sinus or skin infections in the facial or neck regions
Key Symptoms: Lumps or swelling in the face or neck, often persistent and slowly enlarging Abscess formation that may cause pain and discomfort Fistulas or draining sores that ooze pus containing grains or granules Redness, warmth, and tenderness over affected areas Difficulty opening the mouth or swallowing if the infection extends further Occasional fever or general feeling of malaise
Diagnostic & Treatment
Diagnosis Path: Diagnosis typically involves a combination of physical examinations, medical history review, and laboratory tests. A sample of pus or tissue from the affected area is examined microscopically to identify *Actinomyces* bacteria. Imaging studies such as ultrasound, CT scans, or MRI can help determine the extent of tissue involvement and to rule out other conditions.
Treatment Protocols: Treatment generally includes a prolonged course of antibiotics, often several months, to completely eradicate the bacteria. In some cases, surgical drainage or removal of infected tissue may be necessary to reduce the mass of infection and facilitate healing. Maintaining good oral hygiene and managing underlying health issues support recovery and prevent recurrence.
