Orthognathic surgery can affect patients' quality of life. The aim of the present study was to assess changes in quality of life during combined orthodontics-surgery treatment and effect of orthodontist-surgeon teamwork on final patient's satisfaction. Twenty-six orthognathic patients who were referred to oral and maxillofacial department of 3 hospitals in Tehran were included in the study. Orthognathic quality of life questionnaire (OQLQ) was given to patients 1 week before, 4 weeks and 4 months after surgery...

Because titanium alloy (Ti) has the natural advantage of a low elastic modulus, it has become the most commonly used material for the manufacturing of pedicle screws. However, its poor shear strength and osteogenic ability are undesirable properties. The superior osteoinductivity demonstrated by tantalum (Ta) in oral and maxillofacial surgery and joint surgery leads us to assume that the tantalum-coated pedicle screws may have better osteogenic properties and bone anchoring strength. To verify this hypothesis, MC3T3-E1 cells and human mesenchymal stem cells (hBMSCs) were seeded on the surface of Ta and Ti disks to compare the effects of two different metals on cell adhesion, proliferation, and differentiation...

STATEMENT OF PROBLEM: After oral cancer surgery, tissue defects can cause deformity and limited mobility, complicating many essential functions. For patients with mandibular, tongue, and oral floor defects, evidence regarding the effects of maxillofacial prosthetics on their oral health-related quality of life (OHRQoL) is lacking. Therefore, maxillofacial prosthetic reconstruction has been implemented with no clear treatment goals. PURPOSE: The purpose of this study was to identify factors affecting the improvement of OHRQoL by using maxillofacial prosthetic treatment after surgery to repair maxillary, mandibular, tongue, and oral floor defects...

Increased patient exposure has been shown to improve residency training as determined by better patient outcomes. The transition of John Peter Smith Hospital from a level II to a level I trauma center in 2009 provided a unique opportunity to investigate the direct effects of increased patient exposure on residency training in a relatively controlled setting. We evaluated the effect of the transition to a level I trauma center on residency training. In 2014, we examined the annual facility reports and separated the data into 2 groups: level II (2001 to 2008) and level I (2010 to 2013)...

Although surgical treatment of patients on anticoagulation regimens is common practice among oral and maxillofacial surgeons, unexpected and unknown coagulopathies can have devastating and catastrophic consequences for the most routine of procedures. Acquired hemophilia A (AHA) is an extremely rare life-threatening bleeding disorder characterized by autoantibodies directed against circulating coagulation factor VIII. The effects of AHA can produce catastrophic bleeding and hematomas. The effect of this uncontrolled hemorrhage after dentoalveolar surgery can mimic severe head and neck infection by causing dysphagia, odynophagia, and acute airway complications...

REVIEW
Hao Xu, Xiao-Peng Mei, Li-Xian Xu
Cleft palate is one of the most common congenital malformations of the oral and maxillofacial region, with an incidence rate of around 0.1%. Early surgical repair is the only method for treatment of a cleft lip and palate. However, because of the use of inhalation anesthesia in children and the physiological characteristics of the cleft palate itself combined with the particularities of cleft palate surgery, the incidence rate of postoperative emergence agitation (EA) in cleft palate surgery is significantly higher than in other types of interventions...

BACKGROUND: Postoperative nausea and vomiting (PONV) is one of the most common postoperative complications. Despite this, few papers have reported the incidence and independent risk factors associated with PONV in the context of oral and maxillofacial surgery (OMFS). Therefore, we sought to determine the incidence of PONV, as well as to identify risk factors for the condition in patients who had undergone OMFS under general anesthesia. METHODS: A total of 372 patients' charts were reviewed, and the following potential risk factors for PONV were analyzed: age, sex, body mass index, smoking status, history of PONV and/or motion sickness, duration of anesthesia, amount of blood loss, nasogastric tube insertion and retention and postoperative opioid used...

We report a case of junctional rhythm that occurred both preoperatively and later during a portion of general anesthesia. A 19-year-old woman was scheduled to undergo bilateral sagittal split ramus osteotomy after being diagnosed with a jaw deformity. Preoperative electrocardiography (ECG) revealed a junctional rhythm with a slow heart rate (HR). At 90 minutes after anesthesia induction, local anesthesia with 10 mL of 1% lidocaine and 1:100,000 adrenaline was administered. A junctional rhythm appeared 15 minutes after the local anesthesia...

RATIONALE: Lymphomas take up about 14% of all head-neck malignancies, out of which 97% are non-Hodgkin lymphomas (NHL). The clinical courses, treatment responses, and prognoses of NHLs vary with different subtypes and anatomic sites. In the Chinese population (including the Taiwanese), head-neck NHLs are often seen with the tonsils, nasal cavity, nasal sinus, and the nasopharynx. However, oral NHLs are relatively rare. Delay of diagnosis is also often seen in clinical practice. Thus, we present 4 cases with delayed diagnosis of oral maxillofacial NHLs and discuss their clinical manifestations so as to draw a clue that can remind the doctors to take biopsies in time...

Nasotracheal intubation (NTI) is usually required in patients undergoing maxillofacial surgery. Though video-scopes have been demonstrated to perform well in oral endotracheal intubation, limited information is available concerning NTI. The aim of the study is to compare the efficiency of video-scopes and the traditional direct laryngoscopy in NTI. One hundred and eight patients scheduled for elective oro-maxillofacial surgery under nasotracheal intubation general anesthesia were randomly allocated into one of 3 groups of GlideScope, Pentax AirWay Scope, or Macintosh laryngoscope respectively...

INTRODUCTION: Parotid tumours, in addition to the wide variety of types, are histologically complex. Differentiating between benign and malignant tumours in preoperative diagnosis is important in deciding the type of surgery required. Fine needle aspiration cytology (FNAC) is a simple, quick, low-cost, low-invasive and well-tolerated tool used in the preoperative diagnosis of these tumours. MATERIAL AND METHODS: we calculated the sensitivity, specificity, predictive positive value (PPV) and negative predictive value (NPV) of FNAC and computed tomography (CT) in the differentiation of benign and malignant parotid tumours operated between 2010 to 2014 in the oral and maxillofacial surgery department of the University Hospital Miguel Servet...
