Seventeen cases of carcinoma of the hypopharynx and the cervical esophagus who had been treated from 1979 to 1982 at Kitasato University Hospital were investigated retrospectively. Fourteen of them were advanced cases. Nine patients were alive for more than five years. Seven were alive with no evidence of the disease, one was alive with reccurrent disease in the cervical lymph nodes and could not be followed up after five years. Six patients died of original disease, in addition to them, one died suddenly of unknown cause after eleven months and one died of gastric cancer after 39 months. No evidence or original disease was seen in the latter two. Five-year survival rate was 53% (9/17) in total cases and 69% (9/13) excluding two cases died of other causes and two who refused the surgical therapy.
An enquete survey on 106 sudden deafness patients was undertaken with the object of comparing the criteria for prognosis with the patient's own subjective sense of improvement. The results of the inquiry disclosed that subjective improvement in hearing was generally worse than criteria for prognosis, and that comprehensive subjective improvement was even worse. General agreement was noted between criteria for prognosis and the subjective improvement in the "cured" and "unchanged" groups, whereas the agreement was minimal in the "markedly improved" group. This may imply that the "markedly improved" group comprises the most contradictory cases. There was a statistically significant correlation between the subjective improvement and stabilized hearing level, but no significant correlation was noted between subjective improvement and the range of hearing level improvement. This may indicate that the patient tends to judge his prognosis by the degree to which his hearing has improved rather than the degree by which his hearing has improved. These results appear to support some of the arguments against the current criteria for prognosis which were first determined by the Committee on Sudden Deafness of the Ministry of Health and Welfare and are now widely used in Japan.
Preoperative CT images of 96 cases (104 sides) of postoperative cysts of the maxilla, seen between 1982 to 1987, were analyzed as to their modes of distribution in the maxilla. Three scanned planes, i. e., middle inferior meatus level, superior inferior meatus level, and middle meatus level (each level in 0.5cm distance) were included in the study. The distribution were classified into four groups by the combination of the bony destruction seen in both medial and posterior sinus walls. In the middle inferior meatus level, the group only with medial wall destruction, accounts for about 40%. As a general tendency, cysts localize in the central portion of sinus. Polycystic cysts, however, tend to occupy the whole sinus. The expansion of anterior sinus walls decreases as the upper level approachs, and polycystic cysts show more expansion rate than single cysts.
