To evaluate the effects of rapid maxillary expansion (RME) on hearing outcomes and middle ear function in pediatric patients with otitis media with effusion (OME).
Key Findings:
RME was associated with improved hearing thresholds and middle ear status.
In one study, RME showed comparable hearing improvements to ventilation tube placement.
Tympanometry findings shifted toward normal patterns after RME.
RME led to increased nasal fossae width and reduced air-bone gaps.
Complete recovery of auditory function was reported after the retention period.
Interpretation:
RME may serve as a preventive option for managing OME, particularly in patients with craniofacial abnormalities.
Limitations:
Small number of studies with moderate risk of bias.
Nonrandomized study designs hindered meta-analysis.
Inconsistent findings across studies.
No data on incidence or recurrence of otitis media.
Uncertainty regarding long-term durability of improvements.
Conclusion:
Further studies are needed to confirm long-term outcomes and generalizability of RME benefits in OME management.
