Utility of lead thyroid collar in cephalometric radiography.

Objective: To investigate whether the application of thyroid collars (TCs) affects the results of cephalometric study.

Study Design: The Steiner cephalometric analysis of the patients was performed using lateral cephalometric radiographs, which were taken twice for each patient: Once using TCs (TC group; n = 50) and once without using TCs (NTC group; n = 50). A randomized and observer-blinded diagnostic study with head films taken from the two aforementioned groups was performed and results were evaluated with the t-test and Z-test, using GraphPad Prism 4 software.

Simultaneous hemorrhage in intracranial aneurysms and in renal cyst in a case of polycystic kidney disease.

We report an unusual case of simultaneous hemorrhage in intracranial aneurysms and in renal cyst in a case of polycystic kidney disease. A 27-year-old gentleman presented with progressive headache and intermittent vomiting of one month duration. Initial computerized tomography (CT) scan and magnetic resonance imaging/angiography revealed a large mass lesion in the right temporal fossa.

Utility of digital volume tomography in maxillofacial trauma.

Purpose: To assess the diagnostic quality of images generated using the newly developed digital volume tomography (DVT) system and comparing them with conventional images from patients with maxillofacial trauma.

Materials And Methods: The study population included 22 male patients aged 18 to 60 years with a history of maxillofacial trauma. Each patient had undergone conventional radiographic and DVT examinations to analyze the number of fracture lines in the jaws and to compare the images for their diagnostic quality by an oral radiologist and a general radiologist using the χ(2) test.

Utility of color Doppler ultrasound in evaluating the status of cervical lymph nodes in oral cancer.

Objective: The aim was to study the utility of color Doppler ultrasound (CDUS) in diagnosis of cervical lymphadenopathy in oral cancer patients.

Study Design: In a prospective study, 70 cervical lymph nodes in 30 known primary oral cancer patients were evaluated with CDUS during a period of 8 months. The intranodal perfusion sites and vascular resistance were the key CDUS features used to differentiate between reactive and metastatic cervical lymph nodes.

Osteoid osteoma of the femur: masquerading the tethered cord syndrome.

We present an illustrative case of osteoid osteoma of the femur, in an 11 year old male child where the clinical features were masquerading the diagnosis of tethered cord syndrome and lead to the delay in diagnosis.
