Abstract:

Introduction: Obstructive Sleep Apnea (OSA) is a life threatening chronic condition. Previously, OSA is mostly recognized and managed by sleep physicians such as otorhinolaryngologists or neurologists. However, recently, it is attracting attention as it plays an important role in diagnosis and treatment in dental fields such as orthodontics, oral medicine, and oral and maxillofacial surgery. Skeletal surgery can be a first in case of evident dentofacial deformity. Method and Materials: A 25-year-old male patient visited the orthodontics department and oral maxillofacial surgery department for OSA and TMD. As a treatment plan, it was decided to perform an orthognathic surgery after orthodontic treatment accompanied by TMJ treatment. In preoperative examination after completion of preoperative correction, there were no specific findings on both TMJs on the bone scan. In order to improve the accuracy and predict the outcome of surgery, surgery was planned with a virtual surgery program, “Simplant” (Dentsply Sirona, USA). It was planned to perform 5 degree counterclockwise rotation of maxillomandibular complex (center of rotation at zygomatic buttress), 2mm maxillomandibular advance, 5mm advance sagittal split ramus osteotomy, 5mm advance horizontal genioplasty. In order to confirm the success of the planned surgery after surgery, radiography and polysomnography were compared with the preoperative condition. Our objective is to highlight the importance of considering rheumatological diseases as part of the differential diagnosis of limb swelling, especially when the patient is not responding to conventional treatment. RS3PE syndrome, despite being a rare diagnosis, should be considered in older patients presenting with acute distal limb swelling and constitutional syndrome and shows an excellent response to low-dose steroids. Results: Radiography showed that the planned jaw movement and occlusion were obtained. In addition, the airway area and volume were also expanded after the surgery. In the polysomnography performed at 5 months postoperatively, important indicators such as AHI (Apnea-Hypopnea Index) were improved. It was also found that there was an improvement in Epworth Sleep Scale (ESS), which is a survey comparing subjective factors. Conclusion: In OSA cases due to the shape and location of the jaw, surgical methods such as orthognathic surgery and genioplasty can be considered firstly. More satisfying results will be achieved if the patient’s lifestyle is improved.
