Venous pressures were measured within the vein of Galen aneurysm/straight sinus complex in 15 patients with Galenic arteriovenous fistulae and vein of Galen aneurysms. Pressures exceeded normal (less than 5 cm of H2O) in each instance, ranging between 9 and 55 cm of H2O. Measured values exceeding 20 cm of H2O were associated with an increased occurrence of brain calcification. Mean venous press...

AIMS To evaluate the outcomes of transcrestal sinus floor elevation (tSFE) performed with a minimally invasive procedure (Smart Lift technique) combined with the additional use of deproteinized bovine bone mineral (DBBM) or β-tricalcium phosphate (β-TCP). METHODS In a multicenter randomized controlled trial, 38 sites in 38 patients were treated with the Smart Lift technique in association wit...

The aims of this study were to propose a minimally invasive lateral approach technique for maxillary sinus floor elevation (MSFE) with simultaneous implant placement and evaluate the surgical outcome complications technique. This reviewed 49 surgeries MSFE (n = 83) using approach. A circular shape window diameter 5 6 mm an area 20–30 mm2 was made on wall sinus. After Schneiderian membrane, xeno...

Sinus arrest rarely occurs during acute myocardial infarction involving the right coronary artery (RCA) and sinus node (SN) artery. We report a rare case of sinus arrest caused by SN artery occlusion following RCA stenting. A 56-year-old woman with a significant history of RCA stenosis with prior bare metal stenting, presented to the emergency department with anginal chest pain. Initial work up...

Objectives The objective of the present study is to present the current best evidence for enhancement of the vertical alveolar bone height and oral rehabilitation of the atrophic posterior maxilla with dental implants and propose some evidence-based treatment guidelines. Material and Methods A comprehensive review of the English literature including MEDLINE (PubMed), Embase and Cochrane Libra...

AIM The aim of this pilot study was to analyze the interfurcal bone height in relation to the possible need for subsequent sinus floor elevation in patients with advanced periodontitis and furcation involvement of first and/or second maxillary molars. MATERIAL AND METHODS Seventeen dentate patients, who received cone beam computed tomography (CBCT) for detailed preoperative diagnosis and plan...

The observation that a state of elevated blood pressure develops in animals after denervation of the carotid sinus and aortic arch (1) has suggested that certain forms of hypertension in man might similarly be due to a failure of the depressor mechanism. Several studies have lent some support to this hypothesis (2, 3, 4). The evidence may be summarized briefly as follows: direct stimulation of ...

OBJECTIVES The maxillary sinus mucosa is reported to recover to preoperative sterility after sinus floor elevation. However, when drainage of maxillary sinus is impaired, recovery can be delayed and maxillary sinusitis can occur. Therefore, in this study, we investigated the correlations between anatomic variants that can interrupt the ostium of the maxillary sinus and incidence of complication...

Continuous advancements in the field of implant dentistry have provided clinicians with various treatment options to facilitate the placement of dental implants in patients with vertical bone deficits in the posterior maxilla. Today, one of the most common ways to compensate for inadequate vertical bone height is to elevate the sinus floor by tenting of the schneiderian membrane by the implant ...

OBJECTIVES The objectives of this systematic review were to assess the survival rate of implants placed in sites with transalveolar sinus floor elevation. MATERIAL AND METHODS An electronic search was conducted to identify prospective and retrospective cohort studies on transalveolar sinus floor elevation, with a mean follow-up time of at least 1 year after functional loading. Failure and com...
