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...

The stapes is known in several non-mammaliaform cynodonts, although it has only been cursorily studied. Here we thoroughly analyze the stapedial anatomy of several basal cynodonts in a phylogenetic framework. Our study shows that the stapedial anatomy is more variable than previously thought. The morphological variation of the stapes led to the recognition of 11 phylogenetic characters that wer...

Otosclerosis is an otologic disease characterized by disordered resorption and deposition of the otic capsule bone. It can lead to progressive conductive, mixed or sensorineural Hearing Loss (HL). In rare cases, it manifests itself with a tendency for massive bone subsequent formation cavities (“cavitating otosclerosis”). Cavities sometimes realize communication between Cerebrospinal Fluid (CSF...

INTRODUCTION In this article, we present a method able to reasonably predict the bone conduction (BC) gain curve. It provides the advantage of advising patients who will receive little benefit from surgery. MATERIALS AND METHOD A group of 284 cases is studied in an attempt to verify the poststapedectomy predictability of their characteristic gain curve (CGC) to define a pattern, which indicat...

A three-generation family with Saethre-Chotzen syndrome and an isolated case are presented. The proband presented with conductive hearing loss. His mother and grandmother showed minor features of the syndrome including conductive hearing loss. Symptoms of the craniosynostosis syndromes can include stapes ankylosis, a fixed ossicular chain in a too small epitympanum, and small or even absent mas...

Stapes fractures are usually seen in association with tympanic membrane rupture as a result of direct injury or with major skull trauma. However, barotrauma such as blowing the nose is a rare cause of stapes fractures. Furthermore, fracture of the posterior crus is extremely rare. To our knowledge, the combination of a perilymph fistula and acute mastoiditis has not been previously reported.. W...
