Neuroglialchoristoma is a rare cerebral heterotopia typically involving extracranial midline structures of the head and neck, including the nose, nasopharynx and oral cavity. It rarely involves non-midline structures, such as the middle ear, mastoid and orbit. We report the case of a 63-year-old woman with right-sided hearing loss and aural fullness who was diagnosed with neuroglialchoristoma o...

Non-Hodgkin diffuse large B-cell lymphomas of the mastoid that extend from the nasopharynx are extremely rare in children. Moreover, in lymphoproliferative diseases, the presence of otoneurological signs prior to systemic disease involvement is rare. Here, we present a rare case of non-Hodgkin B-cell lymphoma invading the middle ear and mastoid in a 1-year-old boy that mimicked acute mastoiditi...

Vibrotactile thresholds for the glabrous skin of the hand and for the hairy skin of the arm are investigated as a function of frequency in the range from 40 to 2 000 Hz, using a heavy vibrator. These thresholds are expressed as equivalent bone-conduction loss and compared with vibrotactile thresholds determined with bone vibrators on the arm and mastoid for normally hearing and severely hearing...

Squamous cell carcinoma infrequently arises in the middle ear and external auditory canal. Mastoid complex primary carcinoma is extremely rare. The site of origin of these tumors may be obscure when large destructive lesions are encountered at the initial presentation. Imaging techniques may provide a clue as to the origin of these carcinomas. The complementary role of CT and MR is illustrated ...

Attic cholesteatoma with antral extension in tight sclerotic mastoid cavities is a common presentation that creates difficult decision-making intraoperatively. Drilling through a sclerotic and small mastoid cavity, keeping the canal wall intactis often difficult and increases the risk of serious injury. Consequently, a canal-wall-down mastoidectomy is often performed. The endoscopic transcanal ...

the middle ear is the most prevalent disease of childhood. The other areas of the temporal bone which can be contiguous with the middle ear, including the mastoid, petrousus apex and perilabyrinthine air cells, may also be involved. Otitis media can be further divided into acute otitis media (AOM) without effusion, otitis media with effusion (OME), chronic suppurative otitis media (COM) with or...

The authors report a case of a three-year old boy, who presented with discharge from the site of a previously excised postaural lesion reported to have been an epidermoid cyst. It was found at operation that he had a fistulous connection between the site of the excised lesion and a congenital cholesteatoma sac in the mastoid bone. This case demonstrates the rare occurrence of congenital cholest...

Cholesteatoma has been known to be associated with multiple complications either extracranially or intracranially. Among the extracranial complications, mastoiditis and mastoid abscess are the most common. Bezold’s abscess formation with cholesteatoma is a rare occurrence but when present can lead to sinister sequalae if not properly managed. The treatment of cholesteatoma is mainly by surgical...

Cholesterol granuloma is a pathological lesion affecting the mastoid air cells due to partial obstruction of its aireation. It is commonly unilateral. It is usually associated with glue ear with intact ossicles. Histologically, it is characterized by the presence of large pointed crystals and giant cells. Its treatment is either conservative steroid therapy or surgical removal of the granuloma ...

Although pulsatile tinnitus can be audible, objective demonstration of this heartbeat-synchronous sound has rarely been successful. We report a rare case of pulsatile tinnitus in a 44-yr-old female patient, which was induced by a large mastoid emissary vein (MEV) and objectively documented by Doppler sonography of the left posterior auricular region. The tinnitus was intermittent and the patien...
