我们研究了两组颌面间隙感染的临床资料,不论从病因、发病部位、年龄及治疗等方面两组都有显著的不同。1958至1965年为第1组,1975至1981年为第2组。兹分析探讨如下:一般资料1.总人口发病率:第1组1958～1965年。8年中总病例数282例,年均病例数35.25。当时本地区总人口数为10万,年发病率为35.25/10万。第2组1975～1981年。7年中总病例数221例,年均病例数31.57。此时本地区总人数为40万,年发病率为7.89/10万。
We studied the clinical data of two groups of maxillofacial infections, both in terms of etiology, location of disease, age and treatment, etc. There are significant differences between the two groups. Group 1 from 1958 to 1965, Group 2 from 1975 to 1981. The analysis is as follows: General information 1. The incidence of the total population: the first group 1958 ~ 1965 years. The total number of cases in 8 years was 282, with an average annual number of 35.25. At that time the total population in the region was 100,000, with an annual incidence of 35.25 / 100,000. The second group from 1975 to 1981. The total number of cases in 221 was 221, with an average annual number of 31.57. At this point the total number of people in the region is 400,000, with an annual incidence of 7.89 / 100,000.
