title: [Maxillary osteomyelitis secondary to rhinosinusitis in children: case report].
abstract: Rhinosinusitis is a very common childhood condition. Osteomyelitis is an unusual complication, which mainly occurs in toddlers and young children. The most frequent etiologic agent is Staphylococcus aureus. Iniatially, it is characterized by fever, low eyelid edema, unilateral rhinorrhea and ipsilateral palatine edema. Subsequently, abscesses develop in the maxillar yuxtanasal and/or the dental alveolar area. Secondary, it can be complicated by sequestrations, spontaneous expulsion of dental pieces and/or fistula, as well as orbital and intracranial complications. The diagnosis is based on clinical findings and is confirmed by computed tomography findings. The treatment is clinical and surgical. Here we report a five year old child, with rhinosinusitis complicated by osteomyelitis of maxillary bone, mediated by a methicillin-resistant Staphylococcus aureus infection.
