In a ten year period from 1986-95 433 patients were submitted to operation due to benign tumours in the parotid gland in Copenhagen County. In this study we made a retrospective analysis of the surgical outcome. The incidence was calculated to be 6.8 benign tumours in the parotid gland per 100,000 persons per year. The histological distribution showed a frequency of 54% pleomorphic adenomas, 28% adenolymphomas and 18% other tumours. In the observation period there was a 3% recurrence rate in our material, most frequently the pleomorphic adenoma. The risk of permanent damage to the facial nerve was 1% for severe injury and 3% for affection of the ramus marginalis. Frey's syndrome was present in 50% of the patients, moreover the syndrome was observed many years after surgery. The frequency rate reached its highest level about five years postoperatively.
在1986年至1995年的十年间，哥本哈根郡有433例患者因腮腺良性肿瘤接受手术。在本研究中，我们对手术结果进行了回顾性分析。发病率经计算为每年每10万人中有6.8例腮腺良性肿瘤。组织学分布显示，多形性腺瘤的发生率为54%，腺淋巴瘤为28%，其他肿瘤为18%。在观察期内，我们的资料中复发率为3%，最常见于多形性腺瘤。面神经严重损伤导致永久性损伤的风险为1%，边缘支受累的风险为3%。50%的患者出现了味觉出汗综合征，此外，该综合征在术后多年仍可观察到。发病率在术后约五年达到最高水平。
