Summary: Rapid maxillary expansion is an effective treatment for pediatric patients with sleep-disordered breathing and malocclusions. It corrects maxillary deficiency and widens nasal cavities, resulting in reduced air resistance and improved nasal breathing. This study evaluated the changes in upper airway dimensions and facial morphology in pediatric SDB patients treated with RME, comparing with a control group treated with RME for malocclusion.

Summary: The study observed significant skeletal width increase after MARME treatment, with slight decrease noted after 1 year. Postexpansion changes were found to be correlated with palatal cortical bone thickness and inclination of the palatal plane.

Summary: The objective of this study was to evaluate volumetric changes in the upper airway using Cone Beam Computed Tomography (CBCT) in orthodontic patients with maxillary transversal hypoplasia undergoing maxillary disjunction. The influence of factors such as sex, age, and growth pattern on airway volumetric changes was also assessed. The results showed a significant increase in airway volume after palatal disjunction in the treated patients, indicating its importance in improving airway function.

Summary: This study evaluated the skeletal and dental changes from a rapid maxillary expander (RME) and a Ni-Ti leaf spring expander (Leaf) through bidimensional cephalometry, finding similar effects between the two expanders with only minor differences in specific angles.

Summary: The study demonstrated that mini-implants assisted rapid maxillary expansion can improve the anatomic characteristics of the upper airway, such as the total volume of the upper airway and minimum cross-sectional area, contributing to the improvement of respiratory function.

Summary: This study aimed to evaluate the effect of RME on UA function using CFD simulation and found no significant changes in aerodynamic characteristics after RME. Further CFD studies with more cases are needed for a more comprehensive understanding.

Summary: The study evaluated the effects of MCRME on maxillary morphology and upper airway using CFD, showing significant increases in width of palatal bone and nasal cavity after treatment. The volume of nasal cavity and nasopharynx also increased significantly, suggesting that MCRME can improve upper airway ventilation in young adults with MTD.

Summary: This study compared the effects of slow and rapid miniscrew-supported maxillary expansion on upper airway dimensions. The results showed that slow expansion achieved greater expansion in the anterior section of the nasal cavity, and the expander design did not affect the dimensions of the retropalatal or retroglossal airways.

Summary: This study aimed to analyze the upper airway using cone-beam computed tomography at two different time points after rapid maxillary expansion (RPE) treatment. The results showed a significant increase in airway volume and minimal cross-sectional area immediately after RPE treatment and 6 months later.

Summary: The study aimed to investigate the changes in incisive canal (IC) morphology and tooth-canal relationship after MARPE. The results showed that MARPE treatment significantly increased the width and volume of the IC, but did not result in a clinically significant change in the root-canal relationship.

Summary: This article presents the use of a prefabricated expander supported by mini-implants to achieve skeletal expansion without dental side effects, allowing the expander to serve as a skeletal retainer during aligner treatment.

Summary: The aim of this study was to compare skeletal and dental changes after rapid maxillary expansion (RME) and slow maxillary expansion (SME). The results showed that both methods led to a significant increase in dental and skeletal diameters. RME was more effective in expanding the permanent molars, while SME provided better control. Therefore, using SME as an alternative treatment for transverse maxillary deficiency is effective and helpful.

Summary: This study evaluated the density of the midpalatal suture in individuals undergoing maxillary expansion using different treatment methods and found variations in the efficacy of rapid maxillary expansion, surgically assisted rapid maxillary expansion, and miniscrew-assisted rapid palatal expansion in different regions.

Summary: The aim of this study was to investigate the changes in electromyographic activity of temporal and masseter muscles before and after surgically assisted rapid maxillary expansion (SARME) in adult subjects. Data from 20 patients with unilateral posterior crossbite were analyzed retrospectively. The results showed that SARME did not alter the electromyographic activity of the masseter and temporal muscles.

Summary: This study compared the area and minimal section of different parts of the upper airway in cases treated with different methods of microimplant-assisted expansion. The results showed that all cases treated with micro-screw assisted expansion had a significant increase in the total volume of the nasopharynx and oropharynx, as well as the minimum cross-sectional area of the oropharynx. Cases treated with BAME also showed significant changes in the minimal cross-sectional area of the oropharynx and hypopharynx. There were no differences in upper airway changes between cases treated with MARPE and BAME, except for the minimum cross-sectional area of the nasal cavity, which increased for MARPE and decreased for BAME.
