OBJECTIVES The Occupational Health and Safety Administration (OSHA) outlines specific requirements governing the use of respiratory protection for workers dealing with dust or other aerosolized compounds. Health care workers may be exposed to bone dust produced during otologic procedures, creating an occupational hazard. The purpose of this research was to quantify the total suspended particula...

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...

Aberrant internal carotid artery (ICA) is a rare but a very important vascular anomaly of temporal bone. Misdiagnosis of the anomaly may lead to massive hemorrhage and severe complications during otologic procedures. It is essential to keep this anomaly in mind for any otologic surgeon to prevent catastrophic complications. We present a case of aberrant ICA appeared as a nonpulsatile middle ear...

OBJECTIVES To investigate the pathogenesis of one of the most troublesome conditions following ear surgery, a middle-ear cavity problem. METHODS Keratinocyte growth factor (KGF) and its receptor (KGFR), the ratio of proliferating epithelial cells using Ki-67, and the extent of infiltration of B cells and T cells were examined immunohistochemically in 10 ears with a cavity problem, 70 ears wit...

Transcanal endoscopic ear surgery (TEES) is being increasingly used in chronic ear disease for cholesteatoma removal and middle ear reconstruction, reducing the need for a postauricular incision and mastoidectomy. However, TEES is a challenging technique even for the most experienced otologist, requiring one-handed dissection using angled instrumentation. We have therefore developed a high-fide...

The use of an endoscope with varied angulations has allowed the surgeon to explore areas that were often not visualized using standard microscopic procedures. The endoscope has improved knowledge of the complex anatomy of mucosal fold and improved functional interventions in middle ear inflammatory disorders during middle ear surgery; intraoperative evaluation of middle ear anatomy during endos...

BACKGROUND Atlantoaxial rotatory fixation is a condition in which the first and second vertebrae of the cervical spine become interlocked in a rotated position. This condition can result in serious consequences and thus have a significant impact on patients, especially when diagnosis and treatment are delayed. Some cases of atlantoaxial rotatory fixation have been described in association with ...

results utilizing autologous stem cell populations to treat craniofacial defects is a promising field of ongoing investigations. studies show that cartilage stem/progenitor cells (cspcs) are highly chondrogenic and can produce elastic reconstructive material with long-term tissue restoration. conclusions auricular reconstruction surgery is a challenging plastic procedure that requires great exp...
