Recent modification of a common x-ray device may enable physicians to diagnose some otologic diseases more easily and rapidly than with standard methods, a radiologist has reported.
These include acoustic neuromas, congenital neurosensory and traumatic deafness, cholesteatomata, and various forms of otosclerosis, Marc S. Lapayowker, MD, told the Radiological Society of North America.
Using the new technique, called plesiosectional tomography, four films can be taken at four different planes through the temporal bone from a single exposure, Dr. Lapayowker said.
This multilayer method of taking plane x-rays modifies the use of conventional tomography by using a cassette which contains four films rather than one. Intensifying screens are used to separate the films. Both screens and cassette are commercially available.
The technique uses a standard linear tomographic device.
The single exposure method can be performed by most radiographic technicians with some additional instruction, Dr. Lapayowker said.
Exposure time is shorter, thus
