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)
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)
OBJECTIVE Evaluate the effectiveness of surgical treatment of obstructive sleep apnea in a diverse population of children. DESIGN A retrospective case series of pre and post operative polysomnograms (PSG) of pediatric patients with obstructive sleep apnea (OSA). SETTING Tertiary care children's hospital. PATIENTS 48 patients in whom sleep studies were(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)
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)
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)
We have developed a working prototype system for the virtual simulation of temporal bone dissection. The system offers a paradigm from traditional practices by integrating technological advances to provide a safer and more cost effective way to learn fundamental techniques used in temporal bone surgeries. We present our methods to provide a real-time(More)
OBJECTIVES/HYPOTHESIS There is increasing interest in objective assessment of surgeon competence. In the field of otolaryngology, several surgical training programs, including The Ohio State University, the University of Toronto, and Stanford University, have pursued standardized criteria to rate their trainees' performance in the initial steps of temporal(More)
