Accurate upper airway measurements can play a pivotal role in identifying patients with breathing or sleep disorders. Duke Anesthesiology’s Aurelio Alonso, DDS, MS, PhD, is a co-author of a newly published study that investigated the differences between cone-beam computed tomography (CBCT) and acoustic reflection (AR) in calculating airway volumes and areas. The manuscript, titled “When static meets dynamic: Comparing cone-beam computed tomography and acoustic reflection for upper airway analysis,” was published in the October 2016 issue of the American Journal of Orthodontics and Dentofacial Orthopedics.
Subjects with prescribed CBCT images as part of their records were asked to have AR performed. A total of 59 subjects had their five areas of their upper airway measured from CBCT images, acoustic rhinometry and acoustic pharyngometry. Volumes and minimal cross-sectional areas were extracted and compared with software.
According to the authors, results of this study reveal that CBCT is an accurate method for measuring anterior nasal volume, nasal minimal cross-sectional area, pharyngeal volume and pharyngeal minimal cross-sectional area.
Dr. Alonso is the director of orofacial pain for Duke Anesthesiology’s Center for Translational Pain Medicine and notably the first boarded orofacial pain clinician at Duke. This new center further expands the department’s existing clinical and research program in innovative pain therapies by bringing together, under one umbrella, leading basic scientists, clinicians and clinical researchers who have a common core mission of unraveling the causes of painful conditions to better improve patient care. Dr. Alonso is also a pain specialist at Duke Innovative Pain Therapies, a medical pain practice that opened in September of 2016 at Brier Creek in Raleigh.
