fa Surgical treatment modality for facial esthetics in an obstructive sleep apnea patient with protrusive upper lip and acute nasolabial angle ارتودنسی Orthodontics پژوهشي Research For patients with severe obstructive sleep apnea syndrome (OSAS), maxillomandibular advancement (MMA) offers a good treatment option by physically expanding the skeletal framework. However, facial esthetics can be aggravated by MMA in patients with OSAS who have a normally positioned maxilla, a protrusive upper lip, and an acute nasolabial angle. Therefore, surgical treatment planning should be customized according to diverse skeletodental and soft-tissue patterns to produce a favorable change in facial esthetics and sleep function in patients with OSAS. In this case report, good treatment results were achieved in a young female patient with OSAS and skeletal Class II, a normally positioned maxilla, a protrusive upper lip, and acute nasolabial angle by impaction of the maxilla, autorotation/advancement of the mandible, and advancement of the chin. A customized flowchart for surgical treatment planning in OSAS that considers facial esthetics was suggested. <hr><p> <strong>Source: </strong>The Angel Orthodontists</p><p> <a href="http://www.angle.org/doi/abs/10.2319/041512-310.1" target="_blank"><font color="#0000ff">Full Text</font></a></p> Customized surgical treatment plan, Obstructive sleep apnea, Impaction of the maxilla, Autorotation/advancement of the mandible, Advancement of the chin 0 0 http://idai.ir/browse.php?a_code=A-10-32-1954&slc_lang=fa&sid=1 Hyo-Won Ahn 10031947532846009176 10031947532846009176 No Department of Orthodontics, School of Dentistry, Seoul National University, Seoul, South Korea Il-Sik Cho 10031947532846009177 10031947532846009177 No Department of Oral and Maxillofacial Surgery, School of Dentistry, Dental Research Institute, Seoul National University, Seoul, South Korea Keun-Chul Cho 10031947532846009178 10031947532846009178 No Department of Orthodontics, School of Dentistry, Seoul National University, Seoul, South Korea Jin-Young Choi 10031947532846009179 10031947532846009179 No Department of Oral and Maxillofacial Surgery, School of Dentistry, Dental Research Institute, Seoul National University, Seoul, South Korea Jin-Woo Chung 10031947532846009180 10031947532846009180 No Department of Oral Medicine and Oral Diagnosis, School of Dentistry, Dental Research Institute, Seoul National University, Seoul, South Korea Seung-Hak Baek drwhite@unitel.co.kr 10031947532846009181 10031947532846009181 Yes Department of Orthodontics, School of Dentistry, Dental Research Institute, Seoul National University, Seoul, South Korea
