Four cases of neonatal acute maxillary osteomyelitis.

Acute maxillary osteomyelitis was diagnosed in 4 neonates. Three of them were born in the same hospital: a 10-day-old female, a 12-day-old male and a 17-day-old female. Staphlococcus aureus was cultured from all 4, so it was suspected that the infections were hospital-acquired. It is important to inform the hospital where in-fants were born when such infections are diagnosed. Each infant of the patients was treated surgically and with antibiotics. Three responded well, but one developed a brain abscess. CT scanning was very useful in evaluating complications at an early stage. In a patient treated surgically 10 years ago, well-developed sinuses were observed on X-ray examination. Aggressive treatment with both surgery and antibiotics should be pursued for patients with this disease.
