ABSTRACT
Este estudo avaliou, em curto prazo, mudanças após a expansão rápida da maxila em pacientes respiradores bucais e correlacionou esses achados com a qualidade de vida dos pacientes. Este estudo teve como objetivo avaliar se a expansão rápida da maxila (ERM) está associada à melhora na qualidade de vida pós-tratamento. Foram avaliadas 35 crianças (média de idade 10,3 anos) com respiração bucal com hipoplasia maxilar. Os sintomas subjetivos foram avaliados por questionário padronizado de qualidade de vida, respondido pelos pacientes e seus pais ou responsáveis legais pré e pós-ERM. As condições respiratórias subjetivas do pré-tratamento apresentaram melhora significativa seis meses após a ERM. Concluiu-se que a ERM promoveu melhora na qualidade de vida dos pacientes com respiração bucal e hipoplasia maxilar (AU)
This study evaluated short-term changes after rapid maxillary expansion in mouth breathing patients and correlated these findings with their quality of life. This study aimed to evaluate whether rapid maxillary expansion (RME) is associated with improved post-treatment quality of life. Thirty-five mouth breathing children (mean age 10.3 years old) with maxillary hypoplasia were evaluated. Subjective symptoms were assessed by a standardized quality of life questionnaire, answered by patients and their parents or legal guardians before and after RME. Pre-treatment subjective respiratory conditions showed significant improvement six months after RME. It was concluded that RME improves the quality of life for patients with mouth breathing and maxillary hypoplasia (AU)

Abstract Objective: To evaluate, by a three-dimensional study, the volumetric and integumentary effects of rapid maxillary expansion on the nose, in mouth breathing kids with maxillary hypoplasia, in the short term, assessing the possible interference of gender, growth and age on the results achieved. Methods: 120 mouth breathing patients with maxilla hypoplasia were divided into an Experimental Group treated by rapid maxillary expansion (n = 104, 62 males and 42 females, mean age 10.1 years, SD = 2.10, ranging from 5.1 to 13.9 years); and Control Group, constituted by 16 patients (9 males and 7 females, mean age 9.3 years, SD = 2.1 years, ranging from 6.1 to 13.2 years). Patients in the experimental group underwent multislice computed tomography examinations at two different times: (T1) pre-expansion and (T2) post-expansion. The control group was submitted to the same tests at the same time intervals. Six soft tissue variables of the nose were studied, besides the volume and area of the nasal cavity, and the measurement and comparison of data between T1 and T2 were performed using the Dolphin Imaging 11.7 Premium software. Results: The experimental group showed significant mean increases in all soft tissue variables studied (p < 0.005), yet there were no significant changes in the control group. In the comparison between groups, only inclination of the nasal dorsum did not present any significant change. Conclusion: Rapid maxillary expansion may alter the nasal shape and physiology, by anatomical changes in the nose soft tissues, making it an important aid in the treatment of mouth breathing in childhood. Level of evidence: The soft tissues of the nose play an important role in nasal shape and physiology and facial esthetics, and since they are directly related to the nasal valves, they are fundamental for maintenance and stability of the nasal breathing pattern.
ABSTRACT
The aim of this case report was to evaluate the polysomnography indices, air space in the oropharyngeal region and quality of life scores using the OSA-18 questionnaire in a patient diagnosed with obstructive sleep apnea before and after rapid maxillary expansion (RME). It is a case report with a male patient, seven years old, with maxillary hypoplasia, who underwent adenotonsillectomy surgery two years ago, had restless sleep, snore more than five times a week. Pre- and post-treatment diagnostic tests were performed, including nasofibroscopy, polysomnography, computed tomography, orthodontic records and the OSA-18 quality of life questionnaire. The treatment consisted of RME with Hyrax maxillary expander. After six months, the exams were redone. The polysomnographic record before treatment: IAH 2.8/h, after treatment 0.5/h. We concluded that rapid maxillary expansion (RME) in children with OSA appears to be an effective treatment.
