Summary
Rapid maxillary expansion (RME) can improve hearing in children with conductive hearing loss and maxillary constriction. Full hearing recovery was observed after the retention period, highlighting RME
Area of Science:
- Otolaryngology
- Orthodontics
- Pediatric Health
Background:
- Conductive hearing loss (CHL) in children can be associated with maxillary constriction.
- Maxillary constriction may impact the function of the auditory apparatus.
Purpose of the Study:
- To investigate the effects of rapid maxillary expansion (RME) on conductive hearing loss.
- To assess the impact of RME on maxillary constriction and auditory function.
Main Methods:
- A study involving 25 children (aged 6-8 years) with CHL and maxillary constriction.
- Audiometry, tympanometry, and video-otoscopy were used to evaluate anatomical and physiological changes.
- Data collected before expansion, immediately after, and after an 8-month retention period.
Main Results:
- Initial hearing improvement noted for higher frequencies post-expansion.
- Full functional hearing recovery across all frequencies observed after the retention period.
- Tympanic membrane elasticity normalized only after retention.
Conclusions:
- Correction of palatal anatomy via RME can positively influence auditory function in CHL patients.
- RME offers potential benefits for conductive hearing loss secondary to maxillary constriction.
- RME is not recommended for CHL without coexisting maxillary constriction.
