Dural exposure may occur during the course of thinning the tegmen tympani and tegmen mastoideum in mastoid procedure. If large area of dura is exposed or lacerated, cerebrospinal fluid and brain herniation may enter the mastoid cavity. We report a case of a patient with injured dura mater and tegmen mastoideum during mastoidectomy for chronic suppurative otitis media with cholesteatoma managed ...

cerebellopontine angle, the mastoid, the middle ear and the external auditory canal. Of these, the mastoid cavity is the least frequent site of origin. Herein, we report an extremely rare case of congenital cholesteatoma of mastoid origin with extension into the epitympanum and presentation of conductive hearing loss. Computed tomography (CT) displayed anatomic anomalies including ossicular ero...

The Artificial Mastoid Type 4930 has been designed for the calibration of bone conduction hearing aids and bone vibrators used in audiometry. It consists of a mechanical simulation of the human head, incorporating a built-in force transducer to monitor the output of the device to be calibrated. All the components of the Artificial Mastoid have been selected to ensure both excellent long-term st...

A single-stage fitting of a bone-anchored hearing aid (BAHA) implant and abutment with mastoid obliteration both obviates the need for two separate procedures and utilises the BAHA soft tissue reduction in the mastoid obliteration. Such a procedure has good outcomes in terms of osseointegration and achieving a dry ear. We present a 6-patient case series report highlighting the technique of comb...

INTRODUCTION Mastoid osteoma is a rare benign tumour. In this article, the authors report two new cases of mastoid osteoma and discuss the modalities of diagnosis and management. CASE REPORTS Both patients presented with a retroauricular mass that had been slowly increasing in size over several years. The patients consulted for the cosmetic deformity induced by the lesion or moderate tenderne...
