The purpose of this study was to evaluate the follicular fluid selenium status of in vitro fertilization patients in relation to their individual characteristics and treatment outcome. A total of 135 samples of follicular fluid were collected from 112 patients during transvaginal oocyte retrieval. Selenium levels and glutathione peroxidase (GSHPx) activity(More)
OBJECTIVES The aim of this study was to evaluate the accuracy of linear measurements obtained with dental cone beam CT (CBCT) and multislice CT (MSCT) by altering radiation doses using pre-operative planning of the placement of oral implants as a model. METHODS A human cadaver mandible was examined in two edentulous areas and one dentate area using CBCT(More)
PURPOSE To determine the applicability of cone-beam computed tomography (CBCT) in otological imaging, and to compare its accuracy with the routinely used multislice helical CT (MSCT) for imaging of the middle- and inner-ear areas. MATERIAL AND METHODS Thirteen unoperated human cadaver temporal bones were imaged with CBCT and MSCT. Sixteen landmarks of the(More)
OBJECTIVE Magnetic resonance imaging of the head may reveal incidental findings in paranasal sinuses. The purpose of this study was to discover whether similar changes could be identified in the mastoid cavity and middle ear as well. METHODS A group of 50 children undergoing magnetic resonance imaging of the head for suspected intracranial pathology were(More)
Developmental symptomatic C1 canal stenosis is very rare. We describe the computed tomography (CT) and magnetic resonance imaging (MRI) appearances in a 8-year-old child who presented with progressive upper and lower limb neurological symptoms and in whom imaging revealed the medial posterior hemiarches of a bifid C1 to be inturned and compressing the(More)
Panoramic and intraoral radiographs are the basic imaging modalities used in dentistry. Often they are the only imaging techniques required for delineation of dental anatomy or pathology. Panoramic radiography produces a single image of the maxilla, mandible, teeth, temporomandibular joints and maxillary sinuses. During the exposure the x-ray source and(More)
OBJECTIVES Routine dental CT scans were used to describe mandibular first premolar root configurations and canal variations. STUDY DESIGN One hundred twenty dental CT examinations were evaluated for mandibular first premolar root configurations and canal variations regarding shape of root and root canal, incidence of multiple canals, and level of(More)
AIM To compile imaging findings in patients with vocal fold paralysis. MATERIALS AND METHODS A retrospective analysis of the medical charts of 100 consecutive patients, admitted to our department with vocal fold paralysis was undertaken. After laryngoscopy, patients were referred for radiological work-up depending on their clinical history and clinical(More)
CONCLUSION We recommend early surgical exploration and fixation for patients with dislocated or comminuted laryngeal fractures to avoid long-term voice complications. One-third of 33 fracture patients rated their voice after the fracture had healed as fair but altered. OBJECTIVES To examine the indications for and the outcome of surgical management in(More)
Ameloblastic carcinoma is a rare odontogenic tumor exhibiting histologic evidence of malignancy in the primary or recurrent tumor, regardless of whether it has metastasized or not. Most ameloblastic carcinomas are presumed to have arisen de novo, with few cases of malignant transformation of ameloblastoma being apparent. A case is reported of a 21-year-old(More)
