background: the surgical management of cholesteatoma is a controversial issue, particularly regarding intact-canal-wall mastoidectomy (icwm) versus canal-wall-down mastoidectomy (cwdm). the current experiment compared the quality of  visualization in different middle ear structures using icwm with otoendoscopy with findings of cwdm by microscopy.materials and methods: the patients diagnosed wit...

introduction: root canal preparation is an important process in endodontic therapy. nickel-titanium (niti) rotary file system can be used in single length technique (simultaneous technique) without early coronal enlargement, as well as in crown-down method. the purpose of this in vitro study was to compare single length with crown-down methods’ shaping ability using mtwo niti files . materials ...

Background: Hearing loss due to chronic otitis media is common. The purpose of this study was to evaluate hearing before and after canal wall up, canal wall down mastoidectomy and tympanoplasty. Methods: From 2004 to 2007, all patients with chronic otitis media who were admitted at the Department of Otolaryngology, Babol Medical University were studied. For 126 patients' canal wall up, canal wa...

Introduction: First branchial cleft anomalies manifest with duplication of the external auditory canal.   Case Report: This report features a rare case of microtia and congenital middle ear and canal cholesteatoma with first branchial fistula. External auditory canal stenosis was complicated by middle ear and external canal cholesteatoma, but branchial fistula, opening in the zygomatic root and...

introduction: otorrhea and granulation tissue in canal wall down mastoidectomy (cwd) is the common problem in cholesteatoma removal and leads to many discomfort for both the patient and the physician. the main objective in cwd is creating the dry cavity, so the topical antibiotic and acetic acid in variable saturations are used for this purpose. in this study we evaluate the effectiveness of to...

INTRODUCTION  Chronic otitis media (COM) is an inflammatory condition associated with otorrhea as well as large and persistent perforations of the tympanic membrane in some cases. COM can also lead to cholesteatoma. Surgical treatment with canal wall-down and canal wall-up tympanomastoidectomy is considered for both types of illness. The choice of technique is controversial and is dependent on ...

OBJECTIVE To compare the incidence and localization of residual cholesteatomas in canal wall down tympanoplasty with soft-wall reconstruction with results with the canal wall down and open tympanoplasty or canal wall up tympanoplasty. DESIGN Retrospective case-series study. SETTING Tertiary care university hospital. PATIENTS Eighty-five patients (85 ears) with fresh extensive cholesteatom...
