OBJECTIVE The aim of this study was to evaluate the initial and longer term success of closing the air-bone gap (ABG) to 20 dB in ossiculoplasty with canal wall down mastoidectomy. METHODS This study was conducted at a private otologic practice. Patients included those who underwent ossiculoplasty from 1989 to 1996 with canal wall down mastoidectomy, whether primary or revision (33 from a tot...

This paper outlines the features and service benefits of integrated CWDM and OEO metro transport architectures. Following an overview of the xWDM product and network evolution and the ITU-T G.695 standard for CWDM architectures, examples of OEO transport platforms such as Multi-Service Provisioning Platforms (MSPPs) and Regenerative CWDM (R-CWDM) transport platforms are presented. The need for ...

BACKGROUND A mastoid cavity resulting from a canal wall down mastoidectomy can result in major morbidity for patients due to chronic otorrhea and infection, difficulty with hearing aids and vertigo with temperature changes. Mastoid obliteration with reconstruction of the bony external ear canal recreates the normal anatomy to avoid such morbidity. Few have the studied the quality of life benefi...

OBJECTIVES To identify the common presentation(s) and the clinical and operative finding(s) in patients with cholesteatomatous and long-term noncholesteatomatous chronic suppurative otitis media and to adapt a surgical management best suited to ensure long-term safety in these Papua New Guinean patients for whom postoperative follow-up is minimal. DESIGN Retrospective case series. SETTING P...

Attic cholesteatoma with antral extension in tight sclerotic mastoid cavities is a common presentation that creates difficult decision-making intraoperatively. Drilling through a sclerotic and small mastoid cavity, keeping the canal wall intactis often difficult and increases the risk of serious injury. Consequently, a canal-wall-down mastoidectomy is often performed. The endoscopic transcanal ...
