  The Bioadaptive Changes in the Pharyngeal Airway and Hyoid Position Following Mandibular Setback Surgery: A Cephalometric Study
  Author(s): Dain C. Pearl* and Thomas P. Joseph
  
  Objective: Patients who underwent bilateral sagittal split osteotomy with mandibular setback had been evaluated using lateral cephalograms to identify sites of mechanical obstruction that predispose to airway obstruction. The bioadaptive changes that occur in the peri-airway structures in the post-operative period were evaluated. Methods: The hard and soft tissue landmarks used in cephalometry were used to trace and measure the pharyngeal airway space (PAS) and changes in position of hyoid. Amount of mandibular setback, PAS width, PAS area and changes in the hyoid position were recorded. The difference in pre- and post-operative values measured from cephalometric tracings were analyzed statistically using repeated measure ANOVA. Results: The results demonstrated a significant reduction in PAS width and area correspondi.. View More»
