Orthodontics and dentofacial orthopedics, the first specialty of dentistry aims for correction of malocclusion, by movement of teeth, orthopedic changes in jaw bones with growth modulation or by ortho-surgical planning for the varied skeletal malocclusion. Rapid Palatal Expansion (RPE) for treatment of maxillary constriction, growth modulation with forward posturing of lower jaw with myo-functional appliances and surgical repositioning of jaw bones with orthognathic surgery results in alteration of the nasal and oral volume. These changes affect the nasal and oral breathing patterns of the patient and may result in correction of Sleep Breathing Disorders (SBD) like Obstructive Sleep Apnoea (OSA). The conventional methods used to study these changes include 2D cephalometry, rhinomanometry etc. However, with the introduction of 3D evaluation technolo-gy of the craniofacial structures, it has helped orthodontist to evaluate these changes in volume. The contemporary methods include CT, CBCT and MRI. One less commonly explored modality in the field of Orthodontics is Acoustic Rhinometry (AR) and Acoustic Pharyngometry (AP), which is a non-invasive, non-ionizing modality to study upper airway in dynamic state. The AP device uses acoustic reflection technology to accurately map out the size, structure and collapsibility of the oral and nasal airway. The efficacy of the AP is found to be comparable with that of 2D Cephalometry and 3D modalities like CT, CBCT & MRI. This aim of this paper is to highlights the principal, use and importance of AP in the field of orthodontics and to advocate the use of this modality in ortho-dontic practice and training.
