A 34-year-old man presented with tinnitus and conductive hearing loss. CT demonstrated an expansile, air-containing cavity contiguous with mastoid air cells, narrowing the external auditory canal. This is a case of symptomatic pneumocele resulting in an air collection beneath external canal lining, possibly related to an abnormality in mastoid fusion.

During a period of six years, eleven cases, (involving sixteen ears), of osteomyelitis temporalis chronica (otitis media in the broad sense) with cholesterin granuloma, accompanied by experimented studies of cholesterin granuloma in the tympanic cavity of rabbits were reported. Cholesterin granuloma appeared in the tympanic cavity of the rabbits after instilation of a 1 solution of oxalic acid ...

the author studied anatomical variations of the origin of the chorda tympani nerve from the mastoid portion of the facial nerve. the studies were performed on 200 specimens of human temporal bone. it was found that the chorda tympani may arise from the facial nerve in three levels: most commonly from the mid third of its mastoid segment (70%), less commonly from the proximal third (20%), and ve...

Malignancy of the middle ear and mastoid antrum is rare. These malignancies are less than 1%of all head-andneck malignancies. Squamous cell carcinoma is the most common among all malignant tumours. Squamous cell carcinoma of the middle ear and chronic suppurative otitis media may co-exist but no definitive correlation has been proven. Here we are presenting a case of squamous cell carcinoma of ...

INTRODUCTION A chronic discharging ear has been a challenge for the otologists for centuries. The mainstay of treatment for cholesteatoma is surgery and the surgical treatment of choice is modified radical mastoidectomy. The open mastoidectomy technique has been the mainstay of management of chronic ear disease; however this type of surgery is not without its problem. It results in the formatio...
