“…Some studies supported the association between skeletal pattern and the airway, while others did not show such a relationship. A study by Jadhav et al [6] demonstrated that there was no significant correlation between the total airway volume and three sagittal skeletal groups. Alhammadi et al [7] reported that the volume of the palatopharyngeal and glossopharyngeal airways and the narrowest point of the palatopharyngeal airway were greater in Class II skeletal than in other skeletal groups.…”

Aim: This study aimed to evaluate pharyngeal airway dimensions using cone-beam computed tomography (CBCT) in patients with Class I, II, and III malocclusions and normal growth patterns. Methods: All CBCT images were categorized into three groups: Class I (0° < ANB < 4°, −1 mm < Wits < 0 mm), Class II (ANB > 4°, Wits > 0 mm), and Class III (ANB < 0°, Wits < −1 mm). CBCT images were obtained from individuals with normal growth patterns (32 ± 5° = GN/GO – SN), where GN represents gonion, GN is gnathion, and SN equates to the sella-nasion distance. Measurements were taken for total pharyngeal volume, velopharyngeal volume, glossopharyngeal volume, and oropharyngeal volume, and the narrowest area of the airway was measured. ANOVA and Tukey’s post hoc test were used to compare the airway dimensions among skeletal classes I, II, and III. Results: The CBCT images were captured from 90 patients (45 males and 45 females) aged 17 to 39. The mean volume of the total pharyngeal airway, velopharyngeal, glossopharyngeal, and oropharyngeal and the most constricted area were significantly greater in patients with skeletal Class III malocclusion compared to patients with skeletal Class II malocclusion showing normal growth pattern. Total pharyngeal airway, velopharyngeal, and oropharyngeal volumes were lower in Class II patients compared to Class I and III patients with normal growth patterns. There was a significant difference in the pharyngeal space between males and females with Class II malocclusion. Pharyngeal space in female Class II malocclusion was higher than that in males. There was no difference regarding airway space between female and male patients with Class 1 malocclusion. Pharyngeal space between females and males with Class III malocclusion showed no difference. Conclusion: Class III pharyngeal volumes were generally larger in Class I and II malocclusions. Sex differences in the volumes of various pharyngeal spaces were only present in the case of Class II malocclusions. Relevance for Patients: Class II pharyngeal volumes were generally smaller in Class I and III malocclusions.

“…28,29 No significant differences were found among the skeletal malocclusions for the volumes of the upper airways, which is also in line with prior researches. 21,[30][31][32] Other previous authors found a relationship between the upper airway volume and skeletal malocclusion. [33][34][35] Nevertheless, it is not possible to directly compare the results because the methodologies applied in these studies are different.…”

Meu trabalho é dedicado às crianças. Simples assim. A todas as crianças e a algumas, em particular, por tudo que me inspiram. Cresci em uma família de professores. Meus pais e meus avós maternos são educadores preocupados, especialmente, com a educação infantil. Minha bisavó materna, Dulce Gomes de Miranda (in memoriam), só alfabetizada depois de adulta, priorizava e protegia todo o universo infantil que a cercava.Acreditava e defendia o melhor para todas as crianças e muito amor. Sustentava o propósito de que o amor não dava errado nunca. Marcados por esses exemplos, ao tempo que evoluía, compreendia, amplamente, a contribuição do universo infantil na formação do meu caráter. A inesgotável capacidade criativa, a curiosidade como bússola, o olhar tolerante nas relações, o sonho no centro de tudo, o sorriso como "moeda de troca", esses são alguns dos muitos elementos da infância, que precisamos levar para a fase adulta, na perspectiva de construção de tempos mais "saudáveis", associado ao compromisso de assegurá-los a todas as crianças. Cuidar e proteger o universo infantil deve ser uma responsabilidade individual e coletiva de todos. Não existe justificativa para expor uma criança a dor e ao sofrimento. Ela representa o sonho e a esperança. E sonho é tudo.Trabalhar por e para a sua segurança é um dever, sob pena de ameaçar a possibilidade de futuro. Todo talento infantil deve ser estimulado e protegido. Por fim, cito José Saramago:tentei não fazer nada na vida que envergonhasse a criança que fui. AGRADECIMENTOSA Deus, pela benção especial da vida, com a promessa e o compromisso de dedicá-la à verdade absoluta. De jamais me afastar da essência. De nunca me desviar dos propósitos, a mim, reservados pelo PAI. De viver em estado de gratidão, pela imensa distinção de vivenciar as maravilhas, que me rodeiampessoas especiais, que me acrescentam, e um universo infinito de oportunidades. E muito mais, pelo perfeito equilíbrio entre os privilégios e as dificuldades, ensinamento profundo, sobre o valor da dádiva.

Background and Aim: Four premolars extractions are routine procedures for correction of malocclusion, but will inevitably lead to a reduction of tongue space, whether this will weaken the pharyngeal airway remains a controversy. Patients and Methods: Cone-beam computed tomography (CBCT) radiographs of 80 patients who completed four premolar extraction orthodontic treatments were collected and divided into three anteroposterior skeletal groups according to the ANB (angle subspinale to nasion to supramentale) value. Linear, angular, cross-sectional area, and volumetric dimensions of the pharyngeal airway were measured using Dolphin Imaging 11.9 software. One-way analysis of variance and Pearson's correlation coefficient test were performed to assess the intergroup comparisons. Treatment changes were evaluated with two-sample t-tests. Results: In intergroup comparisons, vertical linear and cross-sectional area differences were identified in S-Go/N-Me, VD1, VD1/N-Me, VD2/N-Me, AA, OAA and OMINI (p<0.05), while other measurements showed no significant differences. Angle2, the tilting degree of the pharyngeal airway, showed a positive correlation with ANB (p<0.05). As for the treatment changes, a significant increase was found in the pharyngeal airway in the Class I group (OUA p<0.05, VD1 p<0.001, VD2 p<0.05) and Class II group (VD1 p<0.001. VD2, p<0.05), and inversely, a significant decrease was found in the pharyngeal airway in the Class III group (OAA p<0.05, OMINI p<0.05, OUA p<0.05). No volumetric difference was identified. Interestingly, regarding the preoperative pharyngeal airway size, values trended to the mean value significantly. Conclusion: Four premolar extraction orthodontic treatments did not affect the pharyngeal airway volume except for the vertical liner and cross-sectional area dimensions. The trend of the gold standard suggested a positive influence of four premolar extraction orthodontic treatments.
