Dimensional analysis of the upper airway in obstructive sleep apnea syndrome patients treated with mandibular advancement device: a bi and three‐dimensional evaluation

Introduction. The functional results of surgery in terms of facial mobility are key elements in the treatment of patients. Little is actually known about changes in facial mobility following surgical treatment with maxillomandibular advancement (MMA). Objectives. The three-dimensional (3D) methods study of basic facial movements in typical OSAS patients treated with MMA was the topic of the present research. Materials and Methods. Ten patients affected by severe obstructive sleep apnea syndrome (OSAS) were engaged for the study. Their facial surface data was acquired using a 3D laser scanner one week before (T1) and 12 months after (T2) orthognathic surgery. The facial movements were frowning, grimace, smiling, and lip purse. They were described in terms of surface and landmark displacements (mm). The mean landmark displacement was calculated for right and left sides of the face, at T1 and at T2. Results. One year after surgery, facial movements were similar to presurgical registrations. No modifications of symmetry were present. Conclusions. Despite the skeletal maxilla-mandible expansion, orthognathic surgical treatment (MMA) of OSAS patients does not seem to modify facial mobility. Only an enhancement of amplitude in smiling and knitting brows was observed. These results could have reliable medical and surgical applications.

Success Of Treatment

The aim of this study is to describe a case report of obstructive sleep apnea syndrome and to describe a logical sequence for the treatment of patients who suffer from this disease. Through an interpretation of the polysomnography examination, case history, and clinical examination and by performing cephalometric analysis for sleep apnea, a safe and effective treatment using an intraoral device was indicated. Along these lines, a mandibular advancement device, the Posicionador Luiz Godolfim (PLG), was constructed. After using the device for 4 weeks, the patient underwent another polysomnography, which showed the absence of obstructive sleep apnea. The steps followed for the treatment in this case highlight the importance of and the need for a correct and careful approach for patients with sleep apnea referred to dental office. The approach and sequence presented ensured the success of treatment in this case.
