Twenty-three patients with obstructive sleep apnea syndrome (OSAS) documented by polysomnography underwent maxillomandibular advancement via Le Fort I, and sagittal ramus split osteotomies followed by rigid fixation with miniplates and bicortical screws. Partial turbinectomies and septal reconstruction were simultaneously performed. Pre- and post-operative(More)
PURPOSE The purpose of this study was to analyze the morphologic changes of the airway in obstructive sleep apnea (OSA) patients by helical computed tomography (CT) scanning following maxillomandibular advancement (MMA) surgery. MATERIALS AND METHODS Twenty consecutive OSA patients treated with MMA from 2000 to 2003 at the University of Alabama at(More)
The purpose of this retrospective study was to evaluate relapse, comparing large and small maxillary advancements with four-plate rigid fixation and without bone grafting. All patients had obstructive sleep apnea, and underwent bimaxillary surgery. Standardized cephalometric analysis by two separate examiners was performed on serial radiographs of 20(More)
Results after treatment of severe maxillary and mandibular atrophy (Cawood classes V and VI) are often unsatisfactory and unpredictable. Reconstruction of such severely resorbed edentulous jaws represents a challenge. In maxillofacial surgery, bone grafts from the skull (split calvarial bone grafts) are commonly used for reconstruction of large bone defects(More)
PURPOSE This article describes a series of patients who underwent calvarial bone grafting (CBG) for reconstruction of extremely edentulous jaws for the purpose of implant placement. MATERIALS AND METHODS A retrospective review was conducted of all patients treated with split CBGs to the atrophic maxilla or mandible between 1999 and 2006. All patients were(More)
There are numerous medical and surgical treatment modalities for the management of the sleep apnea patient. Among the medical treatments, weight loss and positive pressure therapy are considered to be the most important. Surgical treatment is directed at increasing the posterior airway space. Among the surgical procedures, tracheostomy,(More)
PURPOSE The purpose of this study was to evaluate the safety and efficacy of intra-articular corticosteroid injections (IACIs) of the temporomandibular joint (TMJ) in children with juvenile idiopathic arthritis (JIA) when administered by an oral and maxillofacial surgeon without imaging guidance. MATERIALS AND METHODS This was a retrospective study of(More)
The objective of this paper is the reconstruction of upper airway geometric models as hybrid meshes from clinically used Computed Tomography (CT) data sets in order to understand the dynamics and behaviors of the pre- and postoperative upper airway systems of Obstructive Sleep Apnea Syndrome (OSAS) patients by viscous Computational Fluid Dynamics (CFD)(More)
