“…(Table 1). The mouth breathing children had maxillary atresia before the adenotonsillectomy, seen upon the frontal view cephalometric radiography, and this aspect is also in agreement with the related studies 1,22,27 . As we compare the control group variables individually upon onset and after 14 months of cephalometric follow up, we found significant differences in variables: Co-A, Co-Gn and Nperp-A, maxillary and nasal widths.…”

Obstructive hypertrophy of the tonsils and/or adenoids is associated with mouth breathing and can lead to facial imbalances. Adenotonsillectomy is not enough to treat the anatomic changes. Facial orthopedic techniques aid in morphological and functional recovery. This prospective longitudinal clinical study aimed to observe craniofacial changes after adenotonsillectomy and to verify the importance of linking rapid maxillary expansion to treatment. Method Fifty-three children of both genders, aged 6 to 12 years, were allocated to: Group 1, 20 children with nasal breathing; and group 2, 33 children with obstructive hypertrophy of pharyngeal and/or palate undergoing adenotonsillectomy. After surgery, this group was subdivided into Group 2A, 16 patients not treated with rapid maxillary expansion; and Group 2B, 17 patients treated with maxillary rapid expansion. Frontal and lateral cephalometric measurements were made prior to surgery and after 14 months. Statistical analysis used the Kruskal-Wallis and Wilcoxon tests – significance level of 5%. Results Adenotonsillectomy balanced transversal, sagittal and vertical growth in both groups, and was more effective in the group undergoing combined treatment. Conclusions Adenotonsillectomy improved the facial growth of children with obstructive hypertrophy, which was more evident when associated with rapid maxillary expansion.

“…Adenoidian facies was already well described in the 19th century, and between 1960 and 1980, Swedish and UK orthodontists emphasized the role of mouth breathing and enlarged tonsils and adenoid in cranial facial changes [16,17,18,19,20,21,22,23,24,25,26]. …”

“…Some of these previous reports present typical cases of obstructive sleep apnea in children but without having polygraphic demonstration of SDB [20,21,22,25,26]. Investigation of the role of orthodontics in nonsyndromic OSA children has been more systematic in recent times [6,7,14,15,28].…”

Rapid maxillary expansion before and after adenotonsillectomy in children with obstructive sleep apnea

In children adenotonsillectomy (AT)\ud is the recommended treatment in the\ud presence of obstructive sleep apnea\ud (OSA) [1]. It should be performed, if\ud needed, in association with nasal inferior\ud turbinate reduction usually\ud with radiofrequency [2]. But as shown\ud in previous reports, upper airway soft\ud tissues treatment is not always successful\ud in completely controlling abnormal\ud breathing during sleep in children,\ud despite the fact that subjective\ud improvement is often reported [3, 4,\ud 5, 6]

“…Maxillary expansion has been used to treat malocclusion growth in patients of various ages 6,[11][12][13][14][15][16][17][18] . Studies state that the post-natal growth reaches its peak in middle adolescence and is dramatically reduced at the end of this period.…”

A expansão da maxila é um procedimento que objetiva o aumento do arco dental maxilar para correção de desvios oclusais. Amplamente empregada em crianças, há controvérsias sobre sua eficácia em adultos, quando o crescimento crânio-facial já atingiu sua maturidade óssea. OBJETIVO: O presente estudo tem como objetivo avaliar modificações cefalométricas decorrentes da expansão da maxila em pacientes adultos, observando as seguintes medidas lineares: largura facial, largura nasal, altura nasal, largura maxilar, largura mandibular e largura molar-maxilar. MATERIAL E MÉTODOS: A amostra constituiu-se de 24 telerradiografias frontais, tomadas antes e imediatamente após as expansões, obtidas de 12 pacientes, ambos os sexos, com idade entre 18 anos e dois meses e 37 anos e oito meses. Todos os pacientes foram submetidos à expansão lenta dos ossos maxilares com o uso do aparelho expansor da técnica denominada "reabilitação dinâmica e funcional dos maxilares". Foi utilizado teste estatístico de Wilcoxon pareado, para amostras relacionadas e nível de significância 5%. RESULTADOS: Ocorreu aumento médio de 1,92mm na largura nasal e altura nasal 2,5mm. Nas medidas lineares largura maxilar e largura mandibular o aumento médio foi de 2,42mm e 1,92mm respectivamente. Para largura facial encontrou-se aumento médio de 1,41mm e largura molar-maxilar 2,0mm, sendo tais alterações estatisticamente significativas, obtidas em um tempo médio de 5,3 meses. CONCLUSÃO: Baseado nos resultados obtidos conclui-se que o uso da expansão maxilar induz o aumento das medidas faciais estudadas em adultos.
