OBJECTIVES To evaluate the efficacy of combined antistaphylococcal and antipseudomonal preoperative antibiotics for preventing surgical site infections following tympanoplasty and mastoidectomy with contaminated cholesteatoma. STUDY DESIGN Retrospective chart review. METHODS Medical records of patients who underwent tympanoplasty ± mastoidectomy for cholesteatoma were reviewed. Only cases c...

Mastoidectomy is one of the most common surgical procedures relating to the petrous bone. In this paper we describe our preliminary results in the realization of a virtual reality mastoidectomy simulator. Our system is designed to work on patient-specific volumetric object models directly derived from 3D CT and MRI images. The paper summarizes the detailed task analysis performed in order to de...

Radio-over-fiber (RoF) schemes offer the possibility of permitting direct access to native format services for the domestic user. A low power requirement and cost effectiveness are crucial to both the service provider and the end user. Here, we present an ultra-low cost and power RoF scheme using direct modulation of commercially-available 1344 nm and 1547 nm VCSELs by band-group 1 UWB wireless...

OBJECTIVES/HYPOTHESIS Long term taste dysfunction after otologic surgery has never been characterized in children. The aim of this study is to determine the rates of gustatory dysfunction in normal and postotologic surgery in children. STUDY DESIGN Cross-sectional study. METHODS One hundred sixty children visiting a tertiary pediatric otolaryngology clinic, 4 to 18 years of age, were recrui...

OBJECTIVE To evaluate the therapeutic effects in terms of disease clearance and hearing improvement of canal wall up mastoidectomy in combination with Type I tympanoplasty in otitis media. METHODS A total of 78 patients (81 ears) with otitis media were treated by canal wall up mastoidectomy in combination with Type I tympanoplasty. The postoperative tympanic membrane morphology, average of pu...

Eleven patients who had been surgically treated from 1988 to 1999 were retrospectively reviewed in order to evaluate the efficacy of ventilation tube insertion and mastoidectomy with, or without, mastoid obliteration for intractable middle-ear cholesterol granuloma. The mean age registered was 17.2 years at the time of surgical treatment. All cases were unilaterally affected. Five ears were tre...

Background: Middle ear cleft space starts from Eustachian tube, and includes middle ear, aditus & mastoid antrum. It develops from 1st visceral pouch. Blockage of middle ear cleft, particularly the aditus can result from a number of reasons. Tympanosclerosis creates obstruction in aeration of middle ear and mastoid antrum. Aims & Objective: To study effect of tympanosclerosis on blockage of mid...

OBJECTIVES/HYPOTHESIS To establish the effect of self-directed virtual reality (VR) simulation training on cadaveric dissection training performance in mastoidectomy and the transferability of skills acquired in VR simulation training to the cadaveric dissection training setting. STUDY DESIGN Prospective study. METHODS Two cohorts of 20 novice otorhinolaryngology residents received either s...

OBJECTIVES/HYPOTHESIS This study explores the influence of selected factors on achievement of competency in mastoid surgery. STUDY DESIGN A prospective study of surgical performance and a retrospective survey of learner and training factors. METHODS The longitudinal performance of 15 residents was evaluated using the mastoidectomy task-based checklist (TBC). The influence of surgical experi...
