Surgical treatment of otitis media with effusion in Maori children

This study aimed to compare the incidence and outcomes of Maori and non-Maori children with otitis media with effusion who underwent myringotomy plus ventilation tube insertion (MVTI).

De-identified extraction of Auckland District Health Board (ADHB) morbidity records belonging to all children who underwent an MVTI procedure between January 1996 and June 2016 at Starship Children's Hospital was performed. Demographic, procedural and outcome data were analysed.

A total of 11 941 children aged less than 10 years underwent at least one MVTI procedure in the Auckland region from January 1996 to June 2016. Of those, 2387 (20%) were Maori and 9554 (80%) were non-Maori. There was no difference in gender, age, length of stay, 30-day readmissions or complications between Maori and non-Maori at index or subsequent surgeries. Maori were not more likely than non-Maori to require subsequent MVTI (P = 0.13). There was no difference between Maori and non-Maori rates of having MVTI alone (P = 0.11) or MVTI with adenoidectomy ± tonsillectomy (P = 0.61).

Some epidemiological evidence suggests that Maori have a higher incidence of middle ear disease in the community. However, this study indicates that there is no difference in the post-operative course between Maori and non-Maori children.
