Introduction
Obstructive sleep apnea syndrome (OSA) is a disease in which apnea
appears due to obstruction of the pharynx during sleep. Several reports
have described that abnormal maxillofacial morphology such as small
mandibular disorder is involved in the pathophysiology of OSA [1,2].
Furthermore, the influence of maxillofacial morphology is large in Asian
races wherein the incidence of OSA due to obesity is low [3].
Here, we discuss about Le Fort I with horseshoe osteotomies (LF+HS) and
mandibular distraction osteotomy for patients with small mandibular
disorders with OSA and bilateral mandibular condyle resorption. After
performing surgery (mandibular distraction osteogenesis, MDO) and then
genioplasty (GP), we encountered a case in which OSA could be improved
in addition to small mandibular disease and malocclusion.
