Results: 1 Intense ERα immunoreactivity localized in the hypertrophic and maturative layer, and some immunoreactivity was found in osteoblasts of mandible and temporal bone, while no immunoreactivity was found in the disc and synovium. 2 The expression of ERα in male rats TMJ cartilage was higher than that in female ones. 3 In the condyle cartilage of male rats, the density of ERα positive cells decreased with age, which kept stable after 16 weeks of age. 4 In the condyle cartilage of male rats, the density of ERα positive cells was stable from birth to 8 weeks, but decreased from 16 weeks to 12 months, while the density in 18-month group recovered to the level of 8 weeks. Conclusion: TMJ is one of target organs of estrogen, and ERα plays an important role in the effect of estrogen on TMJ.

结果：1TMJ中ERα主要在髁突软骨的肥大层和过渡层表达，下颌骨和颞骨的骨细胞也有少量表达，而关节盘、滑膜中几乎无表达；2雄性SD大鼠髁突软骨中ERα的表达明显强于同龄的雌性大鼠；3在雄性大鼠TMJ髁突软骨中阳性细胞密度随年龄增长逐渐降低，16周以后逐渐维持在相对稳定的水平；4雌性大鼠从出生后到8周龄阳性细胞密度基本稳定，在16周龄至12月龄年龄组阳性细胞密度显著降低，而在18月龄后又恢复到8周龄以前的水平。

METHODS 52 cases (56 ears) with different degrees of injuries of temporal bone were involved in the study. The chief complaints included otorrhagia, facial paralysis, hearing loss and vertigo. All patients were examined by HRCT with 1, 1.5 or 2.0 mm thick slices. Axial scans were overlapped when ossicular chain disruption was suspected.
