    Summary

    Acute otitis externa (AOE) is typically a bacterial infection of the external auditory canal, which is most commonly caused by Pseudomonas aeruginosa. Although AOE occurs in all age groups, it is rarely observed in children under 2 years of age [1]. Ear drainage in a neonate is a relatively uncommon finding in the neonatal intensive care unit (NICU) population. This diagnosis requires confirmation by otoscopy [2,3].

    Osteomyelitis of the temporal bone, also referred to as necrotizing otitis externa, is a severe form of infection that may develop typically in diabetic or immunocompromised patients, including premature infants. Similar to simple AOE, Pseudomonas aeruginosa is the most common pathogen [4,5]. In the NICU setting it mostly causes infection in immunocompromised hosts such as premature infants [3].
