Abstract Background Cholesteatoma is an atticoantral disease that potentially causes life-threatening complications. Therefore, canal wall down mastoidectomy a well-established technique to eradicate the disease, especially in extensive cholesteatoma. Aim To evaluate status of dry ear and hearing outcome post-retrograde mastoidectomy. Methods A retrospective study patients with cholesteatoma wh...

Objectives: The aim of this study was to evaluate the effects oxidative stress on thiol-disulfide homeostasis caused by hypotensive anesthesia in mastoidectomy-tympanoplasty cases undergoing controlled hypotension. Methods: Fifty adult patients scheduled for mastoidectomy and tympanoplasty were included study. Anesthesia induced with lidocaine, propofol, rocuronium, remifentanil. maintenance co...

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...

INTRODUCTION Etiopathogenetically, there are two types of chollesteatomas: congenital, and acquired. Numerous theories in the literature try to explain the nature of the disease, however, the question about cholesteatomas remain still unanswered. The aim of the study was to present a case of external ear canal cholesteatoma (EEC) developed following microsurgery (ventilation tube insertion and ...

OBJECTIVES Mastoid obliteration is used to obliterate the mastoid cavity following a mastoidectomy or to prevent the formation of a retraction pocket. This study evaluated the effectiveness of β-tricalcium phosphate and polyphosphate (β-TPP) for mastoid obliteration in middle ear surgeries in prospective human and animal studies. METHODS Twenty patients with chronic otitis media underwent mas...

One of the primary barriers to the acceptance of surgical simulators is that most simulators still require a significant amount of an instructing surgeon's time to evaluate and provide feedback to the students using them. Thus, an important area of research in this field is the development of metrics that can enable a simulator to be an essentially self-contained teaching tool, capable of ident...

Introduction: To reduce incidence of residual cholesteatoma following ear surgery; and to reduce the need for second look “open” mastoidectomy using endoscopic mastoidotomy. Ten-year retrospective chart review of 249 primary cholesteatoma cases (1994-2004) with a minimum follow-up of two years.  The first objective was to evaluate the effectiveness of otoendoscopy in reducing the incidence of “...
