Emergence of Central Sleep Apnea Events After Maxillomandibular Advancement Surgery for Obstructive Sleep Apnea.

Purpose: Central sleep apnea (CSA) can develop after the treatment of obstructive sleep apnea (OSA) with continuous positive airway pressure (CPAP). No studies have identified whether treatment of OSA with maxillomandibular advancement surgery (MMA) can result in CSA. The purpose of our study was to determine the incidence and clinical significance of CSA emerging after MMA surgery to treat OSA.

Preventive Strategies for Patients at Risk of Medication-related Osteonecrosis of the Jaw.

For patients at risk of osteonecrosis of the jaw (ONJ), information can be provided by the pharmaceutical manufacturer, pharmacist, prescribing physician, dentist, and oral and maxillofacial surgeon. Prevention strategies to reduce the incidence of osteonecrosis should be applied as soon as it is determined that a patient will be placed on antiresorptive medication. Proper screening involves a comprehensive oral examination with radiographs followed by oral hygiene instruction and necessary dental treatment; surgical techniques and adjunctive therapies that favor optimum healing of bone and soft tissue decrease the risk of ONJ.

Objective and Subjective Outcomes Following Maxillomandibular Advancement Surgery for Treatment of Patients With Extremely Severe Obstructive Sleep Apnea (Apnea-Hypopnea Index >100).

Purpose: It is important for patients and treating clinicians to know whether maxillomandibular advancement (MMA) surgery is effective when treating patients with obstructive sleep apnea syndrome (OSAS) and an extremely high apnea-hypopnea index (AHI) score. The purpose of this study was to evaluate objective and subjective treatment outcomes after MMA surgery for the treatment of OSAS in patients with a preoperative AHI score higher than 100.

Patients And Methods: This retrospective study included all patients who underwent MMA surgery for OSAS by members of the Department of Oral and Maxillofacial Surgery, QEII Health Science Centre (Halifax, Nova Scotia, Canada) from November 1996 through February 2014.

Management of fractures of the mandibular body and symphysis.

Mandibular fracture, specifically in the symphysis and body regions combined, is the most common facial fracture requiring hospitalization in North America. The primary treatment objective is to restore form and function by achieving anatomic reduction and placing fixation that eliminates mobility of the bone fragments. Several treatment options and surgical techniques are available for performing closed or open reduction.

The effect of rubber dam placement on the arterial oxygen saturation in dental patients.

This study assessed the effect of rubber dam placement on arterial blood oxygen saturation in dental patients; it also determined whether the effects are technique sensitive. The study group consisted of 28 ASA Class I patients who were randomly allocated to one of two groups: Group A--rubber dam isolation of the maxilla (from tooth #14 to #6) and Group B-rubber dam isolation of the mandible (from tooth #19 to #27). A pulse oximeter was used to detect arterial blood oxygen saturation in both groups.
