Purpose. To assess optical coherence tomography (OCT) for guiding design and fit of a prosthetic device for corneal disease. Methods. A prototype time domain OCT scanner was used to image the anterior segment of patients fitted with large diameter (18.5-20 mm) prosthetic devices for corneal disease. OCT images were processed and analyzed to characterize corneal diameter, corneal sagittal height...

Persistent medial column sagittal mobility can be encountered despite successful first tarsometatarsal stabilization if fixation has been limited to the first tarsometatarsal joint. The purpose of the present cadaveric research was to quantify the effect of a third point of fixation from the base of the first metatarsal to the middle cuneiform compared with the traditional isolated first tarsom...

The purpose of this study was to investigate, by cephalometric means, longitudinal alterations in uvulo-glossopharyngeal morphology in adult males and females, at three different ages with 10-year intervals, and to compare the changes between the two genders. The material consisted of three series of cephalograms of 26 males and 24 females, with approximately a 10-year interval between each ser...

Rotational inertial forces are thought to be the underlying mechanism for most severe brain injuries. However, little is known about the effect of head rotation direction on injury outcomes, particularly in the pediatric population. Neonatal piglets were subjected to a single non-impact head rotation in the horizontal, coronal, or sagittal direction, and physiological and histopathological resp...

OBJECTIVE To determine and compare the mean dentoalveolar heights (mm) in different vertical and sagittal facial patterns. STUDY DESIGN Cross-sectional study. PLACE AND DURATION OF STUDY Orthodontics Clinic, The Aga Khan University Hospital, Karachi, from September to November 2013. METHODOLOGY Subjects, aged 15 - 20 years, having fully erupted first permanent molars and central incisors ...

Coronal and sagittal reformatted images generated from axial Target scans through the temporal bone compared favorably with direct scans of cadaver specimens. Oblique reformatted images exhibited significant degradation and did not appear to be helpful in identifying anatomic structures. In patients with suspected temporal bone tumors, Target reconstruction of axial scans followed by coronal an...

Aim: The aim of this study was to analyze nose shape and size in subjects with sagittal facial deformities.

An adolescent female with sickle cell trait presented with acute neurologic deterioration during treatment for pseudotumor cerebri. Cranial computed tomography, initially normal, subsequently revealed multiple hemorrhagic infarctions. Suspected superior sagittal sinus thrombosis was confirmed by cerebral angiography. Superior sagittal sinus thrombosis associated with sickle cell trait is exceed...
