The aim of the study was to evaluate the incidence of mastoiditis in Iceland, especially in children, and the possible correlation with antibiotic usage. Patients with mastoiditis during 1984-2002 were identified and information on antibiotic usage in children in the y 1989-2002 was obtained. 84 patients were diagnosed with mastoiditis during 1984-2002, 52 (62%) of whom were less than 18 y of age. 26 (50%) children were less than 3 y of age. During the y 1999-2002, 28 children were diagnosed with mastoiditis, of whom 15 (54%) were diagnosed with otitis media within a week prior to admission. 11 (73%) were treated with antibiotics and 4 (27%) were not. During 1989-2002 a correlation was detected between decreased antibiotic usage in children and increased incidence of mastoiditis (r=-0.68; p=0.007). Following changes in guidelines for antibiotic prescriptions for otitis media in Iceland during the 1990s, antibiotic usage decreased but the incidence of mastoiditis increased. It is uncertain if this is a causal relationship. It is important to treat otitis media correctly while being alert for complications, especially in young children.
