Maxillary MRSA osteomyelitis in a paediatric patient: non-surgical management.

Methicillin-resistant (MRSA) osteomyelitis of the maxilla is a rare condition in paediatric patients, with limited evidence available for optimal treatment protocols. We present the case of a paediatric patient in the early childhood age group with post-traumatic maxillary osteomyelitis caused by MRSA. The child developed facial swelling following trauma, and imaging revealed maxillary sinus wall thickening and bone erosions. After initial treatment with analgesics, the swelling persisted, leading to surgical intervention and microbiological analysis confirming MRSA infection. The patient was treated with intravenous linezolid and amikacin for 5 days, followed by 8 weeks of oral linezolid. One year post-treatment, the child remained healthy with no recurrence. This case highlights the importance of early diagnosis, tailored antibiotic therapy and conservative surgical management to ensure positive outcomes in paediatric maxillary osteomyelitis cases. Further research is needed to establish standardised treatment protocols for facial osteomyelitis in children.
