Introduction Primary goal in surgical management of chronic otitis media with cholesteatoma is the creation of a dry, safe ear through removal of disease and prevention of recurrence. Canal wall up (CWU) techniques preserve the anatomy of the posterior canal wall, eliminating the need for periodic bowl cleaning and avoiding the risk of recurrent bowl infections. However, the recurrence rate may...
Background and Aim: Recent advances in technology have permitted manufacturers to produce endodontic files from NiTi alloy and rotary systems. According to manufacturers, these files maintain original canal shape better than hand files and reduce treatment time. The aim of this study was to compare a new rotary system (Race) with an older one (Profile) in maintaining the original shape of curve...
The lumbar epidural region was studied using computerized tomography. This technique allows examination of the region in vivo. It confirmed that the spinal canal is oval in the upper lumbar region, becoming triangular lower down, and that the ligamenta flava form a posterior recess to the vertebral canal. Epidural fat is confined to this region between the ligamenta flava and the intervertebral...
the normal and lateral line cycloid scales of a cyprinid fish; alburnoides bipunctatus (blotch, 1782) have been subjected to sem to study their detailed structure. it shows the general architectural pattern of a cycloid cyprinid scale. the focus of the scale is clear and sharp located in the anterior field. circuli are observed in all fields. primary radii which originate from very near the foc...
OBJECTIVE A previous pilot series described a hybrid mastoidectomy technique, canal wall window (CWW), which substituted for the canal wall down (CWD) procedure and involved slitting the posterior canal wall. The current, larger series compares the results of the CWW procedure with conventional surgical techniques. STUDY DESIGN Retrospective analysis of 78 pediatric ears. SETTING Academic t...
Introduction It is widely accepted that cholesteatoma almost invariably requires surgical management. There has been ongoing debate regarding the optimal technique since intact canal wall or canal wall up (CWU) mastoidectomy was developed in the decade following the widespread introduction of the operating microscope in 1953. At the time of the national comparative audit of mastoid surgery over...
OBJECTIVES/HYPOTHESIS To review which type of cholesteatoma surgery, canal wall up (CWU) or canal wall down (CWD), provides the lowest risk for residual and/or recurrent disease in adults with primary acquired cholesteatoma. DATA SOURCES PubMed, Embase, CINAHL, the Cochrane Library, Scopus and Web of Science. STUDY DESIGN We selected articles comparing CWU with CWD, reporting on disease rec...
