OBJECTIVES To measure the orbital volume of unilateral pure blowout fractures with computed tomography before and after surgery and to compare 3-dimensional (3-D) imaging systems. METHODS Twenty-four patients were evaluated with facial computed tomographic scans before and after surgery. Both the orbital volume and the displaced soft tissue volume were(More)
PURPOSE Volume measurements calculated from axial and coronal CT scans were compared to determine which method more accurately determines orbital volume. METHODS Thirty facial CT scans were used to measure 30 normal orbits using an image analysis program (Dextroscope, Singapore). The 3-dimensional volumes determined from axial scans and coronal scans were(More)
We present a very rare case of a 29-month-old boy with acute onset right abducens nerve palsy complicated by inferior petrosal sinus septic thrombosis due to mastoiditis without petrous apicitis. Four months after mastoidectomy, the patient fully recovered from an esotropia of 30 prism diopters and an abduction limitation (-4) in his right eye.
Zygomatic-maxillary (ZMC) complex fractures are a common consequence of facial trauma. In this retrospective study, we present a novel method of ZMC fracture pattern analysis, utilizing three-dimensional visualization of computed tomography (CT) images to record displacement of the malar eminence in a three-dimensional coordinate plane. The pattern of(More)
PURPOSE To describe a modified technique using resorbable panel for endoscopic endonasal reduction of medial orbital wall fracture. METHODS A prospective, small interventional case series involving 2 patients with medial orbital wall fractures that were treated with the modified technique. Postoperatively, patients were evaluated for visual acuity,(More)
OBJECTIVE To compare the performances of the Phadiatop test and the RIDA qLine Allergy in specimens from the South Korean population. METHODS We divided 430 consecutive patient specimens into 4 groups depending on the test results of the 2 assays. We evaluated the degree of agreement between the assays and used the ImmunoCAP sIgE test to identify the(More)
On the cover: Mycobacterium tuberculosis is one of the most virulent pathogens known. Formerly called “consumption,” tuberculosis (TB) has plagued humans since ancient times, and currently causes approximately 1.5 million deaths annually worldwide. It is estimated that roughly 2 billion people harbor the infection, and about 90% of them will never develop(More)
