OBJECTIVE The aim of this study is to investigate a new treatment regimen for macrocystic and microcystic lymphatic malformations (LM) of the head and neck. STUDY DESIGN The study represents a retrospective review of outcomes from new percutaneous treatments for lymphatic malformations. SUBJECTS AND METHODS Thirty-one patients (age range, 2 days to 51(More)
OBJECTIVE 1) To define the surgical anatomy and dimensions of the infracochlear approach to the petrous apex through the use of high-resolution computed tomography and 2) use of digitized images of cadaveric temporal bones for computer simulation of infracochlear access using the Ohio Supercomputer Center/Ohio State University temporal bone simulator.

OBJECTIVE To determine the role of airway fluoroscopy in comparison with other diagnostic modalities in diagnosing the site of partial airway obstruction in children with stridor. DESIGN Prospective study comparing direct laryngoscopy and bronchoscopy with nasopharyngoscopy, airway fluoroscopy, and plain films. Children with stridor or partial airway(More)
We report on our continued development of a virtual simulation for temporal bone dissection that provides stereoscopic display, haptic feedback, and aural simulation into a straightforward, comprehensive learning environment. The multimodal interface provides a seamless simulation for non-deterministic drilling and cutting of bone in the surgical context,(More)
Five cases of prenatally detected neck masses that had a potential for airway obstruction at birth are described. The various options for management of the airway are discussed, including using maternal-fetal circulation until intubation, rigid bronchoscopy, tracheotomy, cyst aspiration, or extracorporeal membrane oxygen support. Congenital abnormalities(More)
OBJECTIVE/HYPOTHESIS To determine the efficacy of a haptic (force feedback) device and to compare isosurface and volumetric models of a functional endoscopic sinus surgery (FESS) training simulator. STUDY DESIGN A pilot study involving faculty and residents from the Department of Otolaryngology at The Ohio State University. METHODS Objective trials(More)
The intra-cochlear distributions of aspartate aminotransferase and glutaminase, prominent enzymes of aspartate and glutamate metabolism, have been studied by quantitative microchemical techniques. Also measured was choline acetyltransferase, the enzyme synthesizing acetylcholine, and a marker for the olivocochlear bundle. Aspartate aminotransferase activity(More)
OBJECTIVES For the past 5 years, our group has been developing a virtual temporal bone dissection environment for training otologic surgeons. Throughout the course of our development, a recurring challenge is the acquisition of high-resolution, multimodal, and multi-scale data sets that are used for the visual as well as haptic (sense of touch) display.(More)
The Temporal Bone Dissection Simulator is an ongoing research project for the construction of a synthetic environment suitable for virtual dissection of human temporal bone and related anatomy. Funded by the National Institute on Deafness and Other Communication Disorders (NIDCD), the primary goal of this project is to provide a safe, robust, and(More)
