Introduction: Maxillary transverse deficiency (MTD) is a pathologic condition frequently seen associated with different malocclusions. Patients with MTD usually have increased nasal resistance, and unfavourable tongue and hyoid bone position, and are predisposed to breathing disorders. Rapid Maxillary Expansion (RME) may increase airway dimensions, and improve breathing and is an effective procedure to correct maxillary deficiency.
Aim: The aim of this study was to evaluate the changes in maxillary width and upper airway spaces in growing children with maxillary transverse deficiency (MTD) after rapid palatal expansion.
Materials and Methods: Five patients (1 male, 4 females; mean age 10.8) with maxillary transverse deficiency were recruited. An expander was placed on D, E and first permanent molars. Cone beam computed tomography was performed before treatment and at the end of the active expansion phase. Measurements were done on the basis of the cone beam computed tomography images by using Romexis 3-D software. Descriptive statistical analysis was performed to calculate the means with corresponding standard deviations (s.d.). t-test was used to compare means. Pearson’s correlation coefficient was calculated to find the correlation between the two variables. p < 0.
Result: In all the cases the values of the parameters were increased after treatment as compared to before treatment but these were not significant (p > 0.05). After treatment, both Nasal Width and Transverse palatal width showed positive and significant correlations with airway volume. Thus, airway volume increased significantly with the increase in Nasal Width and Transverse palatal width (p < 0.05).
Conclusion: Widening of transverse maxillary deficiency after rapid palatal expansion with orthodontic therapy improves upper airway spaces in growing children.
