Our objective was to evaluate the relationship between subjective pulsatile tinnitus and petrous bone pneumatization. Twenty-five patients admitted between January 2012 and March 2012 were assessed. The control group data were obtained by assessment of petrous bone images of 25 cases in which paranasal sinus computed tomography (CT) was performed because of(More)
We evaluated the quantitative diffusion-weighted magnetic resonance imaging (DW-MRI) for parotid masses. Seventy-five patients with 81 focal parotid masses were included. Following DW-MRI, 73 masses underwent surgical biopsy/resection, 6 underwent ultrasonography-guided fine-needle aspiration, and 2 underwent both procedures. The mean apparent diffusion(More)
BACKGROUND Sonoelastography has been used to differentiate malignant from benign lesions in numerous types of tissues including breast, prostate, liver, blood vessels, thyroid, musculoskeletal structures, and salivary glands. PURPOSE To evaluate the efficacy and application of real-time qualitative sonoelastography in the differentiation of benign and(More)
Study Design. Prospective clinical study. Objective. This study compares the clinical results of anterior lumbar total disc replacement and posterior transpedicular dynamic stabilization in the treatment of degenerative disc disease. Summary and Background Data. Over the last two decades, both techniques have emerged as alternative treatment options to(More)
OBJECTIVE The objective of this study was to radiologically determine frontal sinus drainage pathway variations with respect to superior attachment of uncinate process (SAUP) and their effect on prevalence of frontal rhinosinusitis. DESIGN This was a retrospective cohort study. METHODS Computed tomography scans of the 919 frontal sinus sides of 460(More)
The lacrimal drainage system (LDS) is vulnerable to surgical trauma during rhinoplasty. We aimed to investigate the possible effects of the low lateral osteotomies on the LDS during rhinoplasty using active transport dacryocystography (ATD) at the late postoperative stage. Twenty patients who underwent open rhinoplasty were evaluated by ATD between the(More)
Despite advances in technology, the radiologic assessment of certain head and neck lesions may still pose difficulties because of the complex anatomy of this region, the small and mobile structures that this region harbors, and the apposition of mucosal surfaces in the neutral position. Certain maneuvers have been described in the literature to overcome(More)
BACKGROUND Aneurysm rupture results in subarachnoid hemorrhage (SAH) with subsequent vasospasm in the cerebral and cerebellar major arteries. In recent years, there has been increasing evidence that hypercholesterolemia plays a role in the pathology of SAH. It is known that hypercholesterolemia is one of the major risk factors for the development of(More)
AIM The aim of the paper was to evaluate the rate of postoperative pain by using endovenous laser ablation with wave-length of 1470 nm for incompetent saphenous veins in our single center experience. METHODS A non-randomized prospective trial was performed. Patients with symptomatic varicose small saphenous vein and great saphenous vein were considered(More)
Ectopic cervical thymus (ECT) is an uncommon cause for cervical mass in the pediatric age group. Ultrasound and magnetic resonance imaging findings of the mass (located along the thymic descent pathway along the thymopharyngeal tract and has identical echostructure and signal intensities to the native thymus in the superior mediastinum) would lead to the(More)
