Studies on Abnormal Feeling in the Throat

That the disease entity of the abnormal sensation of the laryngeal region is not a simple matter was found as the result of studies on blood, gastric juice, hormones and autonomic nervous system. The

A Scanning Electron Microscopic Study of the Guinea Pig Cochlear Aqueduct

The cochlear aqueduct is the duct that connects the perilymphatic space of the scala tympani with the subarachnoid space. However, its functions are not yet fully elucidated. In the present study on t

Prognosis and Pathogenesis of Sudden Deafness with Scaling Out

Recovery of hearing in sudden deafness is said to be such that the severer the hearing loss and the longer the period from the disease onset to the start of treatment, the poorer the recovery of hearing. However, the prognosis of the so-called scaling out cases has not yet been fully studied. We have therefore studied 96 patients with severest sudden deafness who consulted us within 14 days after disease onset and who had scaling out in all the frequencies. We evaluated the extent to which recovery of hearing could be expected and whether any characteristics are seen in pathogenesis, etc. The results showed that there was no patient who experienced complete recovery, even when treatment was started as early as within 4 days. Recovery of hearing was better in low frequencies than in high frequencies. The site of the lesion was the inner ear in many cases, and some had retrocochlear lesions. Concerning pathogenesis, we think the difference in degree of lesion should be considered important, rather than there may be a substantial difference, compared to that of slight deafness.

Densitometric studies on the shadows of paranasal sinuses in sagittal projection.

In taking a X-ray photography of the head in sagittal projection, it is most important that the center of the X-ray beam passes exactly through the median-sagittal line. If the subject turns his head either to the right or to the left, the paranasal sinuses become denser on one side, leading to erroneous interpretation of the radiographic findings. In order to eliminate such a misinterpretations, studies were carried out on the following: 1) Application of a standard of what degree of head turning to either side would start to influence judgment of the shadow of the paranasal sinuses. 2. Application of a standard to judge whether they are projected to an exact center position or not in actually diagnosing the X-ray films.
