Prevention of Obstructive Sleep Apnea by Functional Genioplasty Clinical Research

Abstract

Background: Obstructive sleep apnea (OSA) is a common sleep disorder under-diagnosed and widespread among adults and children. The aim of this study is to determine the impact of functional genioplasty on the upper airway and on the improvement of nasal breathing. Material and method:A sample of 10 adults with OSA, skeletal open bite and normal body mass index were collected and divided into 2 groups; The first group received orthodontic treatment associated with a functional genioplasty, the second, the control group did not receive genioplasty. Clinical and cephalometric comparison was carried out between the two groups in order to assess the effect of genioplasty on aeropharyngeal space and consequently on respiration.Results: Patients having undergone genioplasty have a higher SNB value, a lower PP-PM as well as an increased Min-EA, EA-PP, EA-PO values. Conclusion:These preliminary results are in favor of the contribution of functional genioplasty, not only in the reduction of the vertical sense, but also in the increase of the aeropharyngeal space
