长期出来,腮腺混合瘤术后局部复发率甚高,究其原因主要为手术不当所致。40年代后期国内外陆续开展了肿瘤加腮腺浅叶(浅部)切除这种常规技术,使得近年来术后复发率明显下降。然而,腮腺混合瘤是涎腺最常见的肿瘤,其发病率远远超过涎腺其它肿瘤,因此在临床上仍不乏见及局部复发的患者来诊。鉴于较初发病例复杂,因而对其认识和进一步治疗引起了普遍关注。本文 For a long time, the local recurrence rate of mixed tumors of the parotid gland is very high. The main reason for this is due to improper operation. In the late 1940s, the conventional technique of tumor plus shallow (superficial) resection of parotid glands was gradually performed at home and abroad, making the postoperative recurrence rate significantly lower in recent years. However, the parotid gland mixed tumor is the most common tumor of the parotid gland, and its incidence is far more than other tumors of the parotid gland, so there is still no clinically seen patients with local recurrence. In view of the complexity of the initial cases, its recognition and further treatment have caused widespread concern. This article
