Osteomyelitis of the lower jaw

Area of Science:

• Pediatric inflammatory diseases
• Osteoarticular pathology
• Differential diagnosis in pediatric bone disorders

Background:

• Chronic non-bacterial osteomyelitis (CNBO) is an inflammatory bone disorder affecting children and adolescents.
• Mandibular osteomyelitis is rare, but CNBO may be more prevalent than previously understood.
• Consideration of infections, malignancy, and other differential diagnoses is essential.

Observation:

• Presents four pediatric cases of osteomyelitis of the jaw without an obvious infection source or fever.
• Clinical examination, X-ray, MRI, and bone biopsies were performed on all patients.
• Treatment included antibiotics, surgical debridement, NSAIDs, and corticosteroids in one case.

Findings:

• Despite similar initial symptoms, the etiology of jaw osteomyelitis remained unclear in all cases.
• The diagnosis of chronic non-bacterial osteomyelitis was considered late in the management.
• Challenges in diagnosis highlight the need for clear terminology.

Implications:

• Emphasizes the importance of considering CNBO in pediatric jaw swelling and pain.
• Highlights the need for consistent international nomenclature to avoid diagnostic delays.
• Timely and accurate diagnosis of CNBO is critical for effective treatment and improved patient outcomes.
