    Objective: To evaluate the correlation between cephalometric measurements of the nasopharynx and oropharynx with clinical and nasofibroscopy findings of adenoids and tonsils hypertrophy, as well as the correlation of airways and breathing patterns with facial patterns in children and adolescents with Angle class III or class III subdivision malocclusion. Methods: This study included 85 white and brown children and adolescents (51 girls) aged 7 to 14 years (mean age: 9.5 years; SD: 1.74 years). Lateral radiographs were used to collect cephalometric data about the nasopharynx, oropharynx and facial patterns. An otolaryngologist determined breathing patterns using patient history, clinical examination and nasofibroscopy. Analysis of variance (ANOVA), the Tukey, Kruskal-Wallis, Pearson and Fisher's exact tests were used for statistical analyses. The level of significance was set at p<0.05. Results: Tonsil obstruction revealed by nasofibroscopy was compatible with cephalometric measurements of the nasopharynx. However, it was not compatible with tonsil hypertrophy. Facial patterns were not correlated with breathing, septal deviation or adenoids, but facial patterns and inferior turbinate were correlated with tonsil hypertrophy. Conclusions: Lateral radiography was an efficient tool for the diagnosis of adenoid hypertrophy, but not of tonsil hypertrophy. There was no association between facial patterns and otolaryngologic findings of airways and breathing, and the variable results are evidence of the fundamental role of an interdisciplinary approach to establish a diagnosis.

    Objective: Evaluate the position and shape ofthe condyle and articular discof the temporomandibular joint (TMJ)in children and adolescents with Angle’s Class III malocclusion with or without subdivision using magnetic resonance imaging (MRI). Methods: The sample consisted of 78 white and brown Brazilian boys (n=31) and girls (n=47) with a mean age of 9.5 years, at a total of 156 TMJs.MRI scans were obtained at treatment baseline. Two observers conducted a qualitative evaluation with the patient’s mouth closed (CM) at habitual occlusion and open (OM).Nonparametric tests were used to assess intra- and interobserver agreement. Results: When condyles were in the CM position, 128 TMJs (82.1%) were concentric.When in OM, the condyles of 44 TMJs (28.2%) showed normal mobility, of 59 (37.8%), hypomobility, and of 53 (34.0%), hypermobility. When the articular disc was in the CM position, discs of 125 TMJs (80.1%) were well positioned, whereas those of 31 TMJs (19.9%) were dislocated. The disc remained interposed in 125 TMJs (80.1%) when in OM position, but was displaced in 31 TMJs (19.9%) after reduction.In 139 TMJs (89.1%), condylar shape was normal, whereas in 17 (10.9%), the condyle was remodeled. The disc was biconcave in 147 TMJs (94.2%) when in CM position and, when in OM position, in 156 TMJs (100%). Conclusion: Important signs of temporomandibular disorders were found, particularly articular disc dislocation. Long-term follow-up and future studies are suggested.
