腮腺区手术虽然以混合瘤为主,但此处病变的诊断和治疗,尚存在许多问题。据Eneroth(1970)的大组病例分析,96％的腮腺肿瘤属于真正的涎腺瘤,其中78％为良性多形性腺瘤。恶性病变的发生率约为17％。在Frazell(1954)所分析的病例中,70％为多形性腺瘤,20％为恶性病变,10％非从涎腺实质所发生。Eneroth(1970)谓后者为问质瘤或所谓假瘤,即各种不同来源的局部肿胀,如炎症、增生及囊肿形成。本文分析材料为1964～1971年所经手术的58例。病人年龄为5～76岁,男女各半。
Although salivary gland surgery is mainly based on mixed tumors, there are still many problems in the diagnosis and treatment of lesions here. According to a large group of cases analyzed by Eneroth (1970), 96% of parotid gland tumors are true parotid adenomas, of which 78% are benign polymorphic adenomas. The incidence of malignant lesions is about 17%. Of the cases analyzed by Frazerl (1954), 70% were pleomorphic adenomas, 20% were malignant lesions, and 10% did not occur from parenchymal parenchyma. Eneroth (1970) suggested that the latter is a stromal tumor or a so-called pseudotumor, that is, localized swelling of various sources, such as inflammation, hyperplasia, and cyst formation. This article analyzes 58 cases undergoing surgery from 1964 to 1971. The patient’s age ranged from 5 to 76 years old, male and female.
