Abstract
|
|
|
|
Background: Otitis media with effusion (OME) is defined as middle ear effusion without acute signs of infection.
OME usually resolves spontaneously; however, persistent OME may require the insertion of a ventilation
tube. This study investigated risk factors for persistent OME in children who undergo ventilation tube insertion.
Methods: Children who were admitted to undergo ventilation tube insertion at Jeju National University Hospital
between August 2015 and July 2016 were enrolled as the case group. Healthy children without persistent
OME from August 2016 to July 2017 were enrolled as the control group. Baseline characteristics and predisposing
factor data were collected using an interview questionnaire. Middle ear fluids were collected from
the case group.
Results: A total of 31 patients underwent ventilation tube insertion. The mean age of the case group was
4.53 years, with a male-to-female ratio of 21:10. Twenty-nine (93.5%) children attended a daycare center,
and 21 (67.7%) had experience with bottle feeding. Fifteen (48.4%) children in the case group and 3 (9.7%)
in the control group first attended a daycare center at <1 year of age (odds ratio=9.96; 95% confidence
interval=2.44-39.70; p=0.001). No bacteria were found in middle ear fluid collected from the 31 operated
children. Nasopharyngeal bacterial colonization was found in 13 (41.9%) and 17 (54.8%) children in the case
and control groups, respectively.
Conclusion: Earlier attendance at a daycare center was the only predisposing factor for ventilation tube
insertion in our study. The aseptic nature of middle ear fluids found in children with OME highlights the
efficacy of antimicrobial use.
