Prospective long-term follow-up after grommet insertion: Hearing and functional health outcomes in children

Objectives

To assess hearing levels and functional health outcomes of children two years after routine grommet surgery with standard care follow-up (discharge to General Practitioner (GP) care or Ear Nose and Throat (ENT) clinic appointment at 4–8 weeks).

Methods

Prospective cohort study of 89 children (average age of 7.98 years) recalled for audiological assessment 2 years after grommet surgery in a large ENT outpatient service in South Auckland, New Zealand. Functional health was assessed using parent-reported responses to the OMQ20 questionnaire.

Results

46 (51.7 %) children had hearing loss in at least one ear with 28 (31.5 %) children having bilateral hearing loss. Māori children had statistically higher odds compared to non-Māori children (odds ratio 5.491, p = .003) to have bilateral hearing loss after controlling for age, household deprivation, gender, season, and mode of follow-up. Most parents reported concerns with their child's hearing, speech, attention-seeking behaviours, and nasal symptoms, but not ear problems. Bilateral hearing loss (p < .001) was found to significantly predict functional health status (total OMQ20 score).

Conclusions

The high prevalence of hearing loss and functional health concerns suggest that the standard follow-up care is not adequately managing children after routine grommet insertion. Māori children are disproportionately impacted, and post-grommet follow-up schedules must consider individualised approaches to address these inequities in outcomes.
