RESULTS OF IMPROVED TECHNIC IN OTOLOGIC SURGERY.

Image-guided otologic surgery

Application of image-guided surgical systems to otologic surgery has been limited by the need for submillimeter accuracy via a fiducial system that is easily useable (i.e. noninvasive and nonobstructive). To overcome these limitations and demonstrate the feasibility of image-guided otologic surgery, a novel fiducial marker system was constructed which attaches to a dental biteblock and has fidu...

Piezoelectric bone surgery in otologic surgery.

The aim of this work has been to evaluate the use of Piezosurgery in the different otological surgical techniques. Piezoelectric bone surgery, also known simply as Piezosurgery, is a new technique for osteotomy and osteoplasty. The equipment consists of two piezoelectric handpieces and two inserts that are connected to a main unit. This unit supplies power and has holders for the handpiece and ...

Electrogustometric assessment of taste after otologic surgery in children.

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...

Further evidence of oxymetazoline's safety in otologic surgery.

Bite-Block Relocation Error in Image-Guided Otologic Surgery

Otologic surgery is undertaken to treat ailments of the ear including persistent infections, hearing loss, vertigo, and cancer. Typically performed on healthy patients in outpatient facilities, the application of image-guided surgery has been limited because accurate (<1mm), non-invasive fiducial systems for otologic surgery are not available. We have developed such a system, which repeatably a...
