External ear canal cholesteatoma after ventilation tube insertion and mastoidectomy.
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 ...
متن کاملFirst Branchial Cleft Fistula Associated with External Auditory Canal Stenosis and Middle Ear Cholesteatoma
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...
متن کاملClassification of External Auditory Canal Cholesteatoma by Computed Tomography
OBJECTIVES We propose here a classification system for external auditory canal cholesteatoma (EACC). We classified the EACC by the computed tomography findings and clinical findings of the patients, and we evaluated the EACC characteristics by the proposed staging system. METHODS Stage classification was done according to the results of temporal bone computed tomography and the clinical findi...
متن کاملUsefulness of Pre-operative High-resolution Computed Tomography in Middle Ear Cholesteatoma
Introduction: Cholesteatoma is traditionally diagnosed by otoscopic examination and treated by exploratory surgery. The need for imaging in an uncomplicated case is contentious. The study assesses the usefulness of a pre-operative high-resolution computed tomography (HRCT) in depicting the status of middle ear structures in the presence of cholesteatoma. Aim: The aim of this study is to evaluat...
متن کاملCASE REPORT External Auditory Canal Cholesteatoma
391 External auditory canal cholesteatoma is an uncommon disease that is characterized by desquamating tissue and bone erosion in older patients. The lesion could start after a microtrauma in the canal, with consequent squamous epithelium proliferation and periostitis. Another possibility is the loss of the skin migration property, which causes retainment of desquamated cells. It is often assoc...
