混合瘤系涎腺中发病率较高的一种疾病,在大唾液腺中腮腺居首位,颌下腺少见,舌下腺极少见。此病复发率较高,特别是单纯瘤体摘除,据国外资料统计高达30～50％。本文重点对我科1970年以来收治并经病理证实为腮腺混合瘤92例进行总结分析。临床资料一、年龄及性别:92例中,男39例,女53例(性别为1:1.4),女性多见。年龄最小8岁,最大67岁,平均37.8岁,其中30～50岁组为72例,约占78.3％。二、病程:从发现病灶到就诊时间最少6个月,最多达25年,平均病程为6年3个月。三、部位:左侧61例,右侧31例,比率,为2:1,左侧多发。分区:耳前区19例,占20.65％,耳前下区63例,占68.50％,下颌角区10例,占10.85％。术中见瘤体位于腮
The mixed tumor is a disease with a high incidence in the parotid gland. In the large salivary glands, the parotid gland is the first, the submandibular gland is rare, and the sublingual gland is rare. The recurrence rate of the disease is relatively high, especially the removal of the tumor alone, according to foreign statistical data as high as 30 to 50%. This article focuses on the analysis of 92 cases of mixed tumors of the parotid gland since our department was admitted in 1970 and confirmed by pathology. Clinical data 1. Age and gender: Of the 92 cases, 39 were males and 53 were females (sex: 1:1.4). Women were more common. The youngest is 8 years old and the oldest is 67 years old with an average of 37.8 years old. Among them, there are 72 cases in the 30-50 age group, accounting for about 78.3%. Second, the course of disease: from the discovery of lesions to treatment for at least 6 months, up to 25 years, the average duration of 6 years and 3 months. Third, the site: 61 cases on the left, 31 cases on the right, the ratio is 2:1, multiple left. Zoning: 19 cases in front of the ear, accounting for 20.65%, 63 cases in the ear before the lower area, accounting for 68.50%, 10 cases in the mandibular angle area, accounting for 10.85%.
