OBJECTIVE This study aimed to clarify the reasons why clinical otosclerosis, a very common disease among Caucasians, is not prevalent among Japanese. STUDY DESIGN The incidence, site, activity, and volume of otosclerotic foci were examined in 1011 temporal bone sections from 507 Japanese individuals. SETTING This study was prepared at the temporal bone(More)
Although field-emission scanning electron microscopy (FE-SEM) has proven very useful in biomedical research, the high vacuum required (10-3 to 10-7 Pa) precludes direct observations of living cells and tissues at high resolution and often produces unwanted structural changes. We have previously described a method that allows the investigator to keep a(More)
BACKGROUND There are currently no effective therapeutic methods for locally recurrent, metastatic, or progressive radioactive iodine (RAI)-refractory differentiated thyroid cancer. However, multitargeted tyrosine kinase inhibitors (TKIs) such as lenvatinib or sorafenib have been approved for patients with RAI-refractory differentiated thyroid cancer as a(More)
Radiation-induced sarcoma usually develops after an interval of more than 10 years from the completion of radiation therapy to the diagnosis of secondary sarcoma. However, the theory of radiation-induced transformation does not rule out postirradiation sarcomas with a short latency period. We experienced the case of a patient with postirradiation(More)
OBJECTIVE The purpose of the current study was to research the pathogenesis of bony destruction of cholesteatoma. STUDY DESIGN We conducted a case report. SETTING The study was performed at Fukushima Medical University. PATIENTS The first case involved a 21 trisomy, whereas the second case was cancer of the hypopharynx. Both cases showed(More)
We examined 395 temporal bones with an intact tympanic membrane to explore the relationship between residual inflammation in the middle ear cavity and development of mastoid pneumatization. Histopathological changes were studied in the middle ear cavity. Mastoid pneumatization was classified as good or poor based on the extent of mastoid tip development to(More)
There are numerous reports on microfissures in the round window niche area, but not many reports have appeared on microfissures in the oval window niche area. In addition, few studies have compared microfissures between the oval and round window niche areas in the same subjects. Hence, the present study investigated the prevalence of microfissures in both(More)
