Background: To determine the most important preoperative factors that affect postoperative coronal parameters of scoliotic curves. Methods: All Adolescent Idiopathic Scoliosis (AIS) patients included in the study were classified according to Lenke and King Classification. The fusion levels were selected according to the rigidity of the existing curves (correction less than 50%), tilt...
Distal junctional kyphosis (DJK) is a radiographic finding in patients that undergo spinal instrumentation and fusion, since there is an abrupt transition between fixed and mobile spinal segments.The true incidence of DJK is variable in literature and seems that has a multifactorial etiology. A consecutive series of 130 patients (mean age 15.6 years) with adolescent idiopathic scoliosis who und...
Coronal cavities are regions of low coronal emission that usually sit above solar prominences. These systems can exist for days or months before erupting. The magnetic structure of the prominence-cavity system during the quiescent period is important to understanding the pre-eruption phase. We describe observations of a coronal cavity situated above a solar prominence observed on the western li...
OBJECTIVE Twist-drill craniostomy (TDC) with closed-system drainage and burr-hole drainage (BHD) with a closed system are effective treatment options for chronic subdural hematoma (CSDH). The aim of this study was to analyze clinical data and surgical results from symptomatic CSDH patients who underwent TDC with closed-system drainage at the pre-coronal point (PCP). METHODS We analyzed data f...
PURPOSE Template-guided implant therapy has developed hand-in-hand with computed tomography (CT) to improve the accuracy of implant surgery and future prosthodontic treatment. In our present study, the accuracy and causative factors for computer-assisted implant surgery were assessed to further validate the stable clinical application of this technique. MATERIALS AND METHODS A total of 102 im...
BACKGROUND To predict success of endoscopic third ventriculostomy (ETV) in patients with obstructive hydrocephalus, we evaluated pre- and post- operative phase-contrast cine magnetic resonance images (PC MRI) on cerebrospinal fluid (CSF), cine flow in basal cisterns around the brain stem, and cervical medullar junction (CMJ) retrospectively. METHODS The study involved 102 patients with mean a...
introduction: this cross-sectional survey determined the dental prevalence of apical periodontitis (ap) in selected iranian population, and evaluated the influence of the quality of root canal treatment (rct) and their coronal restorations (cr) on the periapical status. materials and methods: a total of 1064 panoramic radiographies were evaluated by two observers during 2009. the quality of rct...
Background/Introduction In comparison to open surgery, VATS lung resections are technically challenging operations as the operative field is transformed from a three dimensional multiangle wide view to a two dimensional screen. Therefore careful pre-operative and intra-operative planning is required to complete the procedure safely and successfully. All our patients undergo a Computed Tomograph...
