The most common benign tumour of the parotid is pleomorphic adenoma (PA). Some studies have shown that limited surgery to manage these types of tumours is viable option. Extra-capsular dissection (ECD) is one of these minimally invasive techniques. This study aimed to evaluate the morbidity associated with ECD in managing benign parotid tumours and to demonstrate that the technique can be used outside specialist centres. Twenty-six consecutive patients, diagnosed with benign parotid gland tumours were treated by ECD. Their benign status was determined by history, clinical criteria and fine needle aspiration cytology. Inclusion criteria were a discrete mobile lump, more than 3 cm in diameter and clinical/histological evidence of benign biological behaviour. A single surgeon (the author) operated on all cases. Follow up ranged from 2 to 72 months. In 23 patients, the tumour was located entirely within the superficial lobe of the parotid. Postoperative pathology consisted mainly of 17 PA. Fifteen percent had transient damage to the facial nerve. None had recurrence. ECD seems to be an alternative to superficial parotidectomy for most superficial parotid lumps. It appears to be a safe technique in trained hands.
腮腺最常见的良性肿瘤是多形性腺瘤（PA）。一些研究表明，对这些类型的肿瘤进行有限的手术治疗是可行的选择。囊外解剖（ECD）是这些微创技术之一。本研究旨在评估 ECD 管理腮腺良性肿瘤的发病率，并证明该技术可在专科中心外使用。26 例连续诊断为腮腺良性肿瘤的患者接受 ECD 治疗。他们的良性状态通过病史、临床标准和细针穿刺细胞学来确定。纳入标准为离散的可移动肿块，直径大于 3 厘米，并有临床/组织学证据表明具有良性的生物学行为。所有病例均由一名外科医生（作者）进行手术。随访时间为 2 至 72 个月。在 23 例患者中，肿瘤完全位于腮腺浅叶内。术后病理主要为 17 例 PA。15%的患者面神经一过性损伤。无复发。ECD 似乎是大多数腮腺浅叶肿块行腮腺浅叶切除术的替代方法。在有经验的手中，它似乎是一种安全的技术。
