OBJECTIVE This study was designed to investigate the long-term results using the technique of canal wall up mastoidectomy and reconstruction of the posterior canal wall using bone pâté and auricular cartilage in the treatment of chronic otitis media with cholesteatoma. MATERIALS AND METHODS A retrospective review was performed on 42 patients who underwent canal wall up mastoidectomy and poste...

OBJECTIVE : Management of pediatric cholesteatomas remains controversial. We reviewed our 16-year experience in the surgical treatment of cholesteatomas in children and describe a treatment paradigm. STUDY DESIGN : The authors conducted a retrospective review. METHODS : A total of 106 mastoidectomies (86 for an acquired cholesteatoma and 20 for a congenital cholesteatoma) were performed in ...

A compact configuration for a coarse wavelength-division multiplexer (CWDM) and a coarse wavelength-division demultiplexer (CWDDM) that are based on reflection volume phase gratings is formed. The design and calculated results for four-channel CWDM and CWDDM configurations in the region near 800 nm are presented. Theoretical predictions are experimentally verified with a four-channel CWDDM whos...

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...

OBJECTIVE To review the clinical charts of 45 paediatric patients treated for acute otomastoiditis at the ORL Department of the University of Brescia (Italy) between January 1994 and March 2005 and to discuss the diagnostic workup and the outcome of treatment. METHODS Twenty-six males and 19 females were admitted with acute mastoiditis and subperiosteal abscess. Thirteen of them (28.9%) prese...

Cholesteatoma is a well-demarcated sac of keratinizing squamous epithelium in the temporal bone, which commonly characterized as “skin wrong place. The major goal surgery for cholesteatoma to make ear safe and dry with increasing concern hearing outcome patients. Two main surgical techniques employed are Canal Wall down (CWD) up Mastoidectomy (CWU). In current study, an attempt would be made ev...

OBJECTIVE To describe long-term outcomes of external auditory canal wall reconstruction using bioactive glass ceramic (Ceravital) after canal wall down mastoidectomy. DESIGN Retrospective review of a case series over a 21-year period, with a mean +/- SD follow-up of 13.1 +/- 6.7 years (range, 0.2-20.5 years). SETTING Private otologic practice. PATIENTS The study population comprised 20 co...
