Abstract Objectives The aim of this study was to evaluate the effects of rapid maxillary expansion (RME) and facemask therapy on the soft tissue profiles of class III patients at different growth stages. Materials and Methods Forty-five subjects (23 females and 22 males) were divided into prepubertal, pubertal, and postpubertal groups. Bonded type RME appliances and Petit-type facemasks were fitted to each patient, and intraoral elastics were applied from the hooks of the RME appliance to the facemask. Statistical Analysis All measurements were statistically analyzed with SPSS version 18.0 (SPSS Inc., Chicago, IL, United States) for Windows. Repeated-measures of ANOVA and posthoc Tukey tests were used to compare the groups. Results The soft tissue nasion, pronasale, subnasale, soft tissue A point, and labrale superior landmarks were all displaced forward and downward, and the most dramatic changes were recorded in the pubertal group. The labrale inferior, soft tissue B point, soft tissue pogonion, and soft tissue menton landmarks moved backward and downward in all groups, and the greatest displacements were observed in the pubertal group. Conclusions The soft tissue profiles improved significantly and became more convex in all treatment groups. Although, the most favorable facial changes were observed in the pubertal growth stage, the treatments applied in the postpubertal stage also elicited significant changes and should thus be considered viable treatment options.

OBJECTIVE: To assess short-term tomographic changes in the upper airway dimensions and quality of life of mouth breathers after rapid maxillary expansion (RME). METHODS: A total of 25 mouth breathers with maxillary atresia and a mean age of 10.5 years old were assessed by means of cone-beam computed tomography (CBCT) and a standardized quality of life questionnaire answered by patients' parents/legal guardians before and immediately after rapid maxillary expansion. RESULTS: Rapid maxillary expansion resulted in similar and significant expansion in the width of anterior (2.8 mm, p < 0.001) and posterior nasal floor (2.8 mm, p < 0.001). Although nasopharynx and nasal cavities airway volumes significantly increased (+1646.1 mm3, p < 0.001), oropharynx volume increase was not statistically significant (+1450.6 mm3, p = 0.066). The results of the quality of life questionnaire indicated that soon after rapid maxillary expansion, patients' respiratory symptoms significantly decreased in relation to their initial respiratory conditions. CONCLUSIONS: It is suggested that RME produces significant dimensional increase in the nasal cavity and nasopharynx. Additionally, it also positively impacts the quality of life of mouth-breathing patients with maxillary atresia.

Soft Tissue Changes

The aim of this study was to compare the soft tissue changes influenced by reverse headgear therapy with (RHg+RME) or without (RHg) rapid maxillary expansion with each other and with an untreated Class III control group (C). Study design: RHg group (10 girls, 6 boys, mean chronological age 11.1 years), RHg+RME group (12 girls, 4 boys, mean chronological age 10.8 years) and C group (7 girls, 11 boys, mean chronological age 10.2 years) comprised skeletally Class III patients with maxillary deficiency. Soft tissue measurements were made on lateral cephalograms at the beginning and at the end of the treatment and observation periods. Changes within each group and the differences between the groups were analyzed by paired t-test; the differences between the groups were determined by variance analysis and Duncan test with a significance level p&lt;0.05. Results: The sagittal depth of nose and maxilla, upper lip height and protrusion were significantly increased in treatment groups and the differences were significant when compared to control group (p&lt;0.05). Conclusion: Forward movement of upper lip was more prominent in RHg group. Reverse headgear treatment with or without RME revealed significant soft tissue changes when compared with a growing Class III control group with the same skeletal characteristics.
