conclusions our study shows in terms of figures that measurements of features of the temporal bone made from spiral ct scan images and those directly obtained during surgery are similar to an adequate extent. results twenty cases were included. in the three measurements performed in this study, only the first parameter (distance between the canal and the sigmoid sinus) was significantly differe...

A 6-year-old girl with Down syndrome was referred to our team for joint management. She was having severe speech and language difficulties. Her hearing was assessed, and the pure tone audiometry showed a moderate conductive hearing loss (40 dB) in the left ear and profound hearing loss in the right ear. A CT scan and MRI of temporal bone (Figs. 1 and 2) revealed a hypodense mass in the left tym...

Traumatic perilymph fistula is reported to be rare in infants because of the small size of the infant external meatus. We treated an infant with a traumatic perilymph fistula in the right ear. A metallic wire had penetrated the tympanic membrane. Horizontal-rotatory nystagmus was also observed. Computed tomographic images revealed dislocation of the ossicles. The perilymph fistula was closed un...

A 54-year-old male with partial denture underwent stereotactic radiosurgery with an infrared camera-guided system for a metastatic brain tumor arising from lung cancer. Although this method utilizes a biteplate mounted on the upper jaw to detect head movement, the patient only had four teeth in his upper jaw. In order to stabilize the biteplate, the maxillary denture was fixed to the biteplate ...

BACKGROUND Cholesteatomas are epithelial cysts that contain desquamated keratin. Patients commonly present with progressive hearing loss and a chronically discharging ear. We report an unusual presentation of the disease with an acute hearing loss suffered immediately after prolonged use of a pneumatic drill. CASE PRESENTATION A 41 year old man with no previous history of ear problems present...

The Vibrant Soundbridge (VSB) with stapes clip coupler placement at the stapes head has been used successfully to treat mixed hearing loss. Coupling between the floating mass transducer of the VSB and the stapes head is technically less demanding than incus vibroplasty and is more likely to generate a positive outcome without significantly changing residual hearing or resulting in medical or su...

Since the first description of middle ear osteomas by Thomas in 1964, only few reports were published within the English literatures (Greinwalid et al., 1998; Shimizu et al., 2003; Cho et al., 2005; and Jang et al., 2009), and only one case of the multiple osteomas in middle ear was described by Kim et al., 2006, which arose from the promontory, lateral semicircular canal, and epitympanum. Here...
