Abstract
The effects of respiratory function on craniofacial growth have been studied for decades, and most clinicians now understand that respiratory function is highly relevant to the orthodontic diagnosis and the treatment plan. To evaluate the airway, nasal resistance and airflow tests, nasoendoscopy, and lateral cephalometry have been the primary means used for the last few decades. However, as new generation cone beam computed tomography supplements the diagnosis and treatment planning of patients, 3D analyses of the maxillofacial skeleton and the soft tissues are possible. Because 2D measurements of the nasopharyngeal airway area using lateral cephalograms lacks much of the structural information as the 3D structure is compressed into a 2D image, more accurate diagnosis of the airway morphology has become possible with the aid of the CBCT images. After reorientation of the 3D rendered image, cross sectional analysis including width, length and cross sectional area, as well as volumetric measurement is possible using softwares.
