Patients with sleeping disorders, such as obstructive sleep apnea, (OSA) have a higher risk for postoperative complications after maxillofacial surgery under general anesthesia. The aim of this study was to detect specific complications after oral and maxillofacial surgery. Sixty-nine cases of patients with middle or severe sleep apnea who underwent an operation under general anesthesia in the oral and maxillofacial region were retrospectively analyzed. This group was compared with an age and diagnosis matched group without sleep apnea receiving the same operative treatment...

In 2009 we evaluated the publication of research presented at annual scientific meetings of the British Association of Oral and Maxillofacial Surgeons (BAOMS) 2002-2006, inclusive. Since then, the format of these meetings has changed, there has been a rapid increase in the number of online-only journals, and restraints on time during training and consultant practice have continued. We have therefore investigated the pattern of publication after presentation at these meetings between 2010 and 2014. All abstracts accepted for oral presentations or posters were included, and publication had to follow no more than four years later...

Delayed awakening after general anaesthesia due to psychogenic coma is a phenomenon that rarely presents to the oral and maxillofacial surgeon. A case of psychogenic coma following general anaesthesia for dental extractions is presented here. It is recommended that patients at risk of conversion disorder should be counselled about the risks of psychogenic coma. Early diagnosis of this condition could lead to better patient management.

An odontogenic cause of a lung abscess is often overlooked. A 61-year-old man presented at an emergency department with a productive cough and dyspnoea. He was admitted to the pulmonary ward with a suspected odontogenic lung abscess. A thorax CT scan confirmed the diagnosis 'lung abscess', following which an oral-maxillofacial surgeon confirmed that the lung abscess probably had an odontogenic cause. The patient made a full recovery following a 6-week course of antibiotics, and his teeth were remediated by means of full extraction and the fabrication of immediate dentures...

A 45-year-old man presented with episodes of cough and chest discomfort. CT examination showed multiple nodules of bilateral lungs. The pathology of CT-guided biopsy was consistent with spindle cell sarcoma. FDG PET/CT scan was performed to detect the primary lesion, which showed that in addition to multiple hypermetabolic pulmonary nodules, a mass in the right maxillofacial region with high FDG uptake was also found. A biopsy confirmed spindle cell sarcoma.

Introduction: Intubation can sometimes be difficult in patients with lesions in the mouth floor. Ameloblastoma is a frequently encountered tumor of the maxillofacial area. An extensive lesion might occupy the floor of the mouth, prevent displacement of the tongue, limiting the space for inserting a laryngoscope blade and resulting in difficult intubation even with fiberoptic bronchoscopy. Case presentation: A 66-year-old man (67 kg; 171 cm) with a mental swelling was diagnosed with ameloblastoma and scheduled for surgical resection...

Due to the high biotolerance, favourable mechanical properties, and osseointegration ability, titanium is the basic biomaterial used in maxillofacial surgery. The passive layer of titanium dioxide on the surface of the implant effectively provides anticorrosive properties, but it can be damaged, resulting in the release of titanium ions to the surrounding tissues. The aim of our work was to evaluate the influence of Ti6Al4V titanium alloy on redox balance and oxidative damage in the periosteum surrounding the titanium miniplates and screws as well as in plasma and erythrocytes of patients with mandibular fractures...

PURPOSE: The aim of the present study was to analyze the management of single dental extractions and postoperative bleeding in patients with a diagnosis of factor V deficiency. A careful evaluation of each case will allow the team to categorize the risk and operate safely, minimizing the incidence of intraoperative and postoperative complications. If necessary, the oral-maxillofacial surgeon can choose to do so in collaboration with the hematologist on a case-by-case basis. PATIENTS AND METHODS: The present retrospective study included 5 patients with mild congenital factor V deficiency who had undergone at least 1 dental extraction...

The evaluation of three-dimensional occlusal loading during biting and chewing may assist in development of new dental materials, in designing effective and long-lasting restorations such as crowns and bridges, and for evaluating functional performance of prosthodontic components such as dental and/or maxillofacial implants. At present, little is known about the dynamic force and pressure distributions at the occlusal surface during mastication, as these quantities cannot be measured directly. The aim of this study was to evaluate subject-specific occlusal loading forces during mastication using accurate jaw motion measurements...

PURPOSE: Anxiety is prevalent among medical residents and is associated with fatigue, psychological dysfunction, and burnout. A low personal achievement level is a characteristic of burnout, which-if unaddressed-may lead to medical error and decrease the quality of patient care. This study aimed to assess both personal achievement levels and anxiety levels in current oral and maxillofacial surgery (OMS) residents and to discern a relationship between anxiety severity and perceived personal achievement level among residents...

Cardiovascular disease is a leading cause of death worldwide. We report a case of myocardial infarction for which temporomandibular joint (TMJ) pain was the sole presenting initial symptom. A 28-year-old man presented to a dental clinic reporting TMJ pain. He was an active duty infantry solider in the US Army who was otherwise healthy and in excellent physical condition. He reported a 3-week history of intense throbbing to his left TMJ, specifically during physical activities and weight lifting. On examination by his general dentist, his blood pressure, heart rate, respiratory rate, and temperature were unremarkable...

Maxillofacial injuries are a regular consequence of sport activities that can force athletes to take a long time off from training and competitions. One way to decrease the time that the athlete needs to get back to his or her training exercises after surgery is to use a custom facemask as a coadjuvant in the postoperative recovery phase. This case report describes the case of a 16-year-old male athlete who suffered facial trauma (orbitozygomatic fractures) during a soccer game. After surgery, a facemask was used during the postoperative phase...
