“…22 However, this facial pattern was noted at a lesser degree in children than in adults. 23 Furthermore, the dolico facial pattern and obesity seen in Japanese men were the most important risk factors for OSA patients. 8 The difference between our results and the above cited results is seen in two aspects.…”

Objective: To test the null hypothesis that there is no difference in facial profile shape, malocclusion class, or palatal morphology in Malay adults with and without obstructive sleep apnea (OSA). Materials and Methods: Subjects were 120 adult Malays aged 18 to 65 years (mean Ϯ standard deviation [SD], 33.2 Ϯ 13.31) divided into two groups of 60. Both groups underwent clinical examination and limited channel polysomnography (PSG). The mean OSA and control values were subjected to t-test and the chi square test. Results: Physical examination showed that 61.7% of the OSA patients were obese, and 41.7% of those obese patients had severe OSA. The mean body mass index (BMI) was significantly greater for the OSA group (33.2 kg/m 2 Ϯ 6.5) than for the control group (22.7 kg/m 2 Ϯ 3.5; P Ͻ .001). The mean neck size and systolic blood pressure were greater for the OSA group (43.6 cm Ϯ 6.02; 129.1 mm Hg Ϯ 17.55) than for the control group (35.6 cm Ϯ 3.52; 114.1 mm Hg Ϯ 13.67; P Ͻ .001). Clinical examination showed that the most frequent findings among OSA groups when compared with the control group were convex profiles (71.7%), Class II malocclusion (51.7%), and V palatal shape (53.3%), respectively; the chi square test revealed a significant difference in terms of facial profile and malocclusion class (P Ͻ .05), but no significant difference in palatal shape was found. Conclusion:The null hypothesis is rejected. A convex facial profile and Class II malocclusion were significantly more common in the OSA group. The V palatal shape was a frequent finding in the OSA group. (Angle Orthod. 2010;80:37-42.)

Skeletal Class III malocclusion is one type of dentofacial deformity that significantly affects patients’ facial aesthetics and oral health. The orthodontic treatment of skeletal Class III malocclusion presents challenges due to uncertainties surrounding mandibular growth patterns and treatment outcomes. In recent years, disease-specific radiographic features have garnered interest from researchers in various fields including orthodontics, for their exceptional performance in enhancing diagnostic precision and treatment effect predictability. The aim of this narrative review is to provide an overview of the valuable radiographic features in the diagnosis and management of skeletal Class III malocclusion. Based on the existing literature, a series of analyses on lateral cephalograms have been concluded to identify the significant variables related to facial type classification, growth prediction, and decision-making for tooth extractions and orthognathic surgery in patients with skeletal Class III malocclusion. Furthermore, we summarize the parameters regarding the inter-maxillary relationship, as well as different anatomical structures including the maxilla, mandible, craniofacial base, and soft tissues from conventional and machine learning statistical models. Several distinct radiographic features for Class III malocclusion have also been preliminarily observed using cone beam computed tomography (CBCT) and magnetic resonance imaging (MRI).
