Craniofacial microsomia is one of the of maxillofacial dysostoses. This syndrome has a number of features associated with clinical manifestations which should be taken into account at steps of the diagnosis and treatment of such patients. The degree of mandibular hypoplasia in this pathology can vary from 0 to 3, and it is inversely proportional to the integrity of the articular disc on the side of the lesion. An increased mechanical load on a healthy joint leads to its dysfunction and dislocation of the articular disc at the healthy side. In addition to hypoplasia of bone structures, craniofacial microsomia is accompanied by subatrophy of masticatory muscles and that in couple leads to malocclusion and myodynamic imbalance. Before drawing up a treatment plan it is necessary to study the state of the TMJ on both sides using multislice computed tomography (MSCT) and magnetic resonance imaging (MRI). The approach to treatment should be individual, combined, staged, based on the severity of the symptom complex.","PeriodicalId":51864,"journal":{"name":"Radiology Research and Practice","volume":"200 1","pages":""},"PeriodicalIF":2.7,"publicationDate":"2022-08-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"76966717","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The study included 96 patients (mean age: 49.52 ± 9.64 years). Chest radiograph in the PA projection and echocardiography were performed. In CR the measurement of the cardiothoracic ratio (CTR) was performed. Assuming CTR > 0.50, heart silhouette enlargement was diagnosed. In echocardiography, four types of left ventricular geometry were assessed: normal geometry (NG), concentric remodeling (CR), concentric hypertrophy (CH), and eccentric hypertrophy (EH). It was shown that patients with an enlarged heart silhouette were characterized by a significantly more frequent occurrence of left ventricular hypertrophy (LVH) on echocardiography than patients with a nonenlarged heart silhouette. In the subgroup of patients with LVH compared to the subgroup of patients with normal left ventricular geometry, CTR values are statistically significantly higher, and heart silhouette enlargement is significantly more frequent. The criterion \"CTR > 0.49\" estimates LVH with a sensitivity of 93.3% and specificity of 82.7%, which translates into a high accuracy of 84.4%. By analyzing the prediction of left ventricular geometry types, high accuracy of CH prediction was obtained using the \"CTR > 0.49\" criterion of 80.2% (with a high sensitivity of 84.0% and a satisfactory specificity of 60.0%) and a high accuracy of EH prediction using the \"CTR > 0.52\" criterion of 71.9% (with high sensitivity 80.5% and low specificity 36.8%), as well as low CR prediction accuracy of only 57.3% (with low sensitivity 36.7%, even if high specificity 78.7%).
