OBJECTIVES Combined mastoidectomy is generally preferred to tympanoplasty alone when treating patients with chronic otitis media (COM), particularly when temporal bone computed tomography (TBCT) shows that the mastoid cavity contains opacification of soft tissue density. However, in cases with Eustachian tube dysfunction, a mastoid cavity volume may be a burden to its function. We hypothesized ...

A case of cutaneo-cutaneous fistula superior to the external auditory canal extending from the mastoid skin to the skin over the zygoma is reported. The adult patient presented with recurrent discharge and swelling of the skin over the zygoma and mastoid bones. Definitive treatment was in the form of complete excision of the fistula tract.

Temperomandibular joint ankylosis is a relatively common anomaly affecting the face causing facial asymmetry which necessitates multiple surgeries to restore function and form to near normal. The most important diagnostic aid in T.M.J ankylosis is radiography ranging from conventional radiography to C.T scans. This is a case report of an unusual radiographic presentation of bilateral T.M.J anky...

A 34-year-old man lacerated his forehead and was brought to the emergency room. Skull films (fig s. 1 A and 1 B) showed small and large rad iolucent , air-containing ce lls extending from the upper posterior reg ion of the mastoid area on the left side, across th e temporal-occipital suture into th e squamous portion of the occipital bone, and into the posterior part of the parietal bone. The s...

Abstract In conventional bone conduction (BC) devices, a vibrator is typically applied to the mastoid or condyle processes. Recently, however, BC-sound presentations facial parts such as nose have also been investigated. As face among most complex structures in human body, BC sounds presented are likely show different perception and propagation characteristics from those parts. We measured hear...
