A rare case of neonatal osteomyelitis: Zygomatic bone infection presenting as a recurrent lid abscess with discharging Sinus: A case report

Osteomyelitis of the neonatal facial bones, particularly the zygomatic bone, is rare and challenging to diagnose early due to vague presenting symptoms. In this report, the authors present a unique case of a neonate with zygomatic bone osteomyelitis, initially presenting as a recurrent upper eyelid abscess that later developed into a discharging sinus. Incomplete abscess drainage can lead to the spread of contiguous infection. Upon presentation, we performed complete drainage, bony debridement, and sequestrectomy. Histopathological examination confirmed chronic osteomyelitis. An extended course of intravenous antibiotics followed by oral antibiotics was administered, which resolved the eyelid abscess. This case highlights the importance of considering zygomatic bone osteomyelitis in recurrent eyelid abscess cases to ensure timely and appropriate intervention.
