Facial prognathism, which is a problem in some orthodontic patients, is characterized by a number of cephalometric changes. Most clinicians use SNA angle in lateral cephalometric analysis to evaluate the amount of maxillary prognathism. Since SNA angle is not a reliable measurement for maxillary prognathism, and taking into account that the amount of prognathism changes in relation to cranial a...

The aim of this study was to evaluate the oropharyngeal (OP) and nasal passage (NP) volumes along with various airway variables of patients with normal nasorespiratory functions having different dentofacial skeletal patterns and to evaluate the correlations between different variables and the airway. One hundred and one patients (57 males and 44 females, aged 14-18 years) having pre-treatment c...
متن کاملObstructive sleep apnea and abnormal cephalometric measurements. Implications for treatment.
The position of the hyoid bone, which anchors much of the tongue musculature, is often abnormally low in patients with obstructive sleep apnea syndrome (OSAS). Cephalometric measurements, frequently used to measure SNA and SNB angles, can also provide information on the posterior airway space (PAS), the mandibular plane, and the hyoid bone. This information is useful in determining the appropri...
