The temporomandibular joint is an oval fibrous plate that completely divides the joint and accommodates irregularities existent in the bone articular surfaces.
To study the frequency of temporomandibular joint disk abnormalities among Colombian subjects.
We studied 120 temporomandibular joint disks obtained from fresh cadavers arrived in the Instituto de Medicina Legal, in Cali Colombia. These were analyzed according to subject's dental status and age.
Nineteen percent of disks had small erosions. In 7.5% of disks there were wider erosions or perforations. Twenty six percent of discs were very thin and this alteration was seen mostly in people aged 50 years or older.
These results are intermediate between those who claim that disk perforations are rare and those who had shown tile opposite. The loss of dental pieces seems to be a risk factor leading to such disk perforation.
颞下颌关节是一个椭圆形纤维板，它完全分隔关节并容纳骨关节面中存在的不规则之处。
研究哥伦比亚受试者中颞下颌关节盘异常的发生率。
我们研究了从抵达哥伦比亚卡利市法医学研究所的新鲜尸体上获取的120个颞下颌关节盘。根据受试者的牙齿状况和年龄对这些关节盘进行分析。
19%的关节盘有小糜烂。7.5%的关节盘有更广泛的糜烂或穿孔。26%的关节盘非常薄，这种改变主要见于50岁及以上的人群。
这些结果介于声称关节盘穿孔罕见的研究结果和显示相反情况的研究结果之间。牙齿缺失似乎是导致这种关节盘穿孔的一个危险因素。
