INTRODUCTION: Perforation of the Schneiderian membrane is the most common complication in sinus floor augmentation (SFA). When volume of grafting is qualified to prevent enlargement of the membrane perforation, lack of bone volume may occur in optimal site. CASE PRESENTATION: SFA was performed in sites #24 to 26 in a 63-year-old male. However, a 10-mm size perforation of the Schneiderian membrane occurred in site #26. Although the sinus cavity was grafted with deproteinized bovine bone mineral (DBBM) after repair of membrane perforation, insufficient bone formation was observed on palatal and distal aspects of site #26 at 5 months after SFA...

BACKGROUND: Mucous retention cyst refers to a cyst made by expansion due to the blockage of the salivary gland near the maxillary sinus, and it is surrounded by epithelial cells. Most of them are small; therefore, they cannot be found well and are frequently with antral polyp. The aim of this study was to evaluate the clinical prognosis of sinus bone graft in patients with mucous retention cyst. METHODS: This study was performed retrospectively on 23 patients who had sinus bone graft...

PURPOSE: To report the outcome of graftless osteotome sinus floor elevation (OSFE) in order to evaluate whether apical bone gain depends on the initial residual bone height and whether the initial residual bone height has an influence on the amount of marginal bone loss. Furthermore the study aimed to assess if perforations of the Schneiderian membrane or residual bone height are potential predictors of implant survival. MATERIALS AND METHODS: In this retrospective study all patients were included who were treated between 2001 and 2010 and received dental implants in combination with OSFE in a private practice...

Endoscopic endonasal approach has been successfully used for the management of pituitary tumors; however, the loss of septal mucosa especially around sphenoethmoidal recess and posterior nasal septum might be a disadvantage of this technique. The aim of this study is to describe a variation of the endonasal approach, "double nasoseptal flap" technique in endoscopic transsphenoidal pituitary surgery, and to evaluate its outcomes. The technique depends on fully harvested bigger nasoseptal flap on one side and smaller on the other...

BACKGROUND Infective endocarditis (IE) involving the mitral valve can but rarely lead to complete atrioventricular block (CAVB). CASE REPORT A 74-year-old man with a history of infective endocarditis caused by Streptococcus gordonii (S. gordonii) presented to our emergency room with fever and loss of appetite, which had lasted for 5 days. On admission, results of serologic tests pointed to severe infection. Electrocardiography showed normal sinus rhythm with first-degree atrioventricular block and incomplete right bundle branch block, and transthoracic echocardiography and transesophageal echocardiography revealed severe mitral regurgitation caused by posterior leaflet perforation and 2 vegetations (5 mm and 6 mm) on the tricuspid valve...

The current used parameters for transseptal puncture (TSP) under fluoroscopic guidance is from left atriography and need to be verified by precise anatomic measurement. From February 2009 to July 2013, consecutive patients who received computed tomography (CT) were included. Landmarks and parameters were preliminary studied by right atriography, and further evaluated on the CT images of 1001 patients. A method (CTP-2) was proposed for guiding TSP. In right anterior oblique 45° view, the CTP-2 method was defined by points C, T, and P, and 2 areas: point C is in coronary sinus; point T is at a distance of dCT (usually 1...

The Na(+)/Ca(2+) exchanger (NCX) plays a major role in myocardial Ca(2+) homoeostasis, but is also considered to contribute to the electrical instability and contractile dysfunction in chronic atrial fibrillation (AF). Here we have investigated the effects of the selective NCX blocker SEA0400 in human right atrial cardiomyocytes from patients in sinus rhythm (SR) and AF in order to obtain electrophysiological evidence for putative antiarrhythmic activity of this new class of drugs. Action potentials were measured in right atrial trabeculae using conventional microelectrodes...

INTRODUCTION: Sinus grafts are a safe and predictable treatment for increasing bone volume in the posterior maxilla. Common complications include membrane perforations and postoperative infection. Little is published with regard to late-onset infection except as it relates to periimplantitis. This report presents a case of late sequestration of bovine bone mineral graft fully consolidated within host lamellar bone, 8 years postsinus lift. Histology revealed mature lamellar bone encapsulating well-integrated particles of bovine bone material with evidence of devitalization and marrow spaces filled with a dense neutrophil infiltrate and a filamentous mixed microbial flora...

Maxillary sinus membrane perforation has been reported as the most common intraoperative complication during sinus augmentation, potentially leading to postoperative infection and consequent loss of graft or even implant failure. Numerous anatomical factors have been demonstrated to affect membrane tearing. However, careful use of proper instrumentation, such as a reamer, seems to play an important role in minimizing the incidence of these complications. Hence, the aim of the present study was to (1) investigate the reliability of reamer drilling for lateral window preparation; (2) examine the incidence of membrane perforation; and (3) study the factors that might influence membrane perforation...
