Which cephalometric measurements have strong correlations with adult obstructive sleep apnea (OSA) as reported by Neelapu?

The measurement that demonstrates strong correlations with adult obstructive sleep apnea (OSA), as reported by Neelapu, is the reduced pharyngeal airway. This correlation is significant because the pharyngeal airway space is critical in determining airflow during sleep. A narrow or reduced pharyngeal airway can lead to increased resistance during respiration, potentially contributing to episodes of apnea or hypopnea.

In patients with OSA, the anatomical features that compromise the airway can be identified through cephalometric analysis. A reduced pharyngeal airway indicates that there is less space for airflow, making it more likely for airway obstruction to occur during sleep. This understanding helps to guide treatment options and interventions aimed at improving airflow and reducing sleep apnea episodes.

While other measurements might also relate to OSA, they do not have the same level of correlation as the reduced pharyngeal airway. For example, increased palatal height and increased mandibular angle may influence dental and facial structures but do not directly account for the airway obstruction seen in OSA. Similarly, a shortened vertical dimension might affect occlusion and facial aesthetics, but it does not have a clear, direct impact on airway dynamics compared to the pharyngeal space. Thus, the emphasis on
