چکیده

INTRODUCTION The aim of this study was to evaluate the condition of the ossicular chain in patients requiring surgery for cholesteatoma. MATERIALS AND METHODS In a retrospective analysis, the destruction of the individual and combined bony structures of the ear was described in 166 patients with cholesteatoma who went through surgery in our Otology Center between 2003 and 2009. RESULTS Total (55.4%) or partial (30.7%) erosion of the incus was the most common pathology. In some cases, the long process (25.9%) and the body of incus (4.8%) were also involved. Erosion of the stapes superstructure occurred more commonly than a total loss of the bone (40.9% vs. 25.9%). Erosion of the malleus was least common. Completely intact ossicles were present in 5.5% of cases. Total ossicular erosion with an intact footplate (18.7%) and incudostapedial erosion (18%) was the most common combination of ossicular erosion. All patients with incudostapedial erosion had advanced disease (85% with multiple site involvement). CONCLUSION Widespread cholesteatoma results in greater ossicular erosion and poor hearing outcomes.

Comparison of Preoperative Temporal Bone CT with Intraoperative Findings in Patients with Cholesteatoma

Introduction: Cholesteatoma is traditionally diagnosed by otoscopic examination and treated by surgery. The necessity for imaging in an uncomplicated case is controversial. This study was planned to investigate the usefulness of a preoperative high-resolution computed tomography (HRCT) scan in depicting the status of middle ear structures in the presence of cholesteatoma and also to compare the...

Study of Correlation of Pre-Operative Findings with Intra-Operative Ossicular Status in Patients with Chronic Otitis Media

Introduction: Chronic otitis media (COM) has been broadly classified into mucosal and squamous subtypes. COM types are associated with erosion of the ossicular chain. The aim of the present study was to correlate the type of COM, the site of perforation/retraction, and the type of disease pathology with the pattern and degree of ossicular chain necrosis.   Materials and Methods: A prospecti...
