目的探讨腮腺多形性腺瘤的治疗方法。方法通过对1992—2009年江苏省徐州市第六人民医院口腔科收治的148例腮腺多形性腺瘤患者的临床资料进行总结,比较分析腮腺浅叶切除术(88例患者)与腮腺区域性切除术(60例患者)两种术式治疗腮腺多形性腺瘤的效果。结果采用腮腺区域性切除术治疗的病例,术后瘢痕、局部凹陷畸形、暂时性面瘫、涎瘘、Frey综合征及腮腺功能等方面明显优于采用腮腺浅叶切除术的病例。两种术式的术后复发率差异无统计学意义。结论应根据肿瘤的部位及大小选择不同的术式,对界限清楚、体积较小的腮腺浅叶多形性腺瘤应尽量采用腮腺区域性切除术,预防面部凹陷畸形,减少并发症;对过大或边界不清的肿瘤仍宜采用传统腮腺浅叶切除术,以减少复发。

Is ultrasound alone sufficient for imaging superficial lobe benign parotid tumours before surgery?

Ultrasound (US) is a valuable technique for the assessment of salivary gland disease and regional nodes. When used in combination with fine needle aspiration cytology (FNAC) or core biopsy it has a high sensitivity and specificity in the diagnosis of tumours. The role of additional cross-sectional imaging (computed tomography (CT) or magnetic resonance (MR)) to help with the diagnosis of benign parotid tumours is questionable except when there is deep lobe extension or the suggestion of malignancy. We investigated 37 FNAC-confirmed benign parotid tumours in patients who had undergone both US and CT or MRI investigations, to find out whether cross-sectional imaging had provided any further useful diagnostic information before operation. Three patients had bilateral Warthin tumours. Tumours ranged in size from 11 to 45 mm (mean 22). Of the 37 patients 35 (95%) had a clearly delineated mass in the superficial lobe of the parotid on US and no further information was gained from additional CT or MRI. On US 34 patients (92%) had features suggestive of a benign tumour, and three had features suggestive of malignancy but these were found to be benign on FNAC and after operation. CT or MRI confirmed these suspicious findings. In two different patients the deep margin was not visible on US (suggestive of deep lobe extension) and this was confirmed on MRI. The mean time delay between US and CT or MRI was four weeks (range 1-44). These results suggest that additional imaging is not required in most patients with a sonographically and FNAC confirmed benign lesion confined to the superficial lobe of the parotid and confirmed by FNAC or biopsy examination.     

功能性腮腺切除术治疗腮腺深叶良性肿瘤

目的：探讨保存功能性外科在腮腺深叶肿瘤切除术中的应用及疗效。方法：17例腮腺深叶良性肿瘤患者,其中位于深叶者12例,累及浅深2叶者5例,直径均≤3 cm。采用制备筋膜腺体瓣并预留出将要切除的肿瘤及周围腺体的方法,完整切除腮腺深叶及肿瘤同时保存腮腺浅叶功能。结果：全部患者的手术均顺利完成,创口均Ⅰ期愈合,无涎瘘,外形满意;暂时性面瘫发生2例（11．76％）。17例均获随访,随访时间6～24个月,平均11个月。未见肿瘤复发;面瘫基本消失。结论：应用功能性腮腺切除术治疗腮腺深叶良性肿瘤能有效保存腺体功能,减少面部凹陷畸形及味觉出汗综合征等并发症。     

Synchronous unilateral pleomorphic adenomas in the parotid gland: report of a case

A 45 year old man presented with a swelling on the right side of his face of 12 months duration. Subsequent magnetic resonance imaging (MRI) scans revealed he did in fact have two discrete tumours of his right parotid gland. Following a superficial parotidectomy and dissection of the deep lobe, histopathology revealed both tumours to be pleomorphic adenomas. We discuss the clinicopathological findings and implications in contemporary surgical management of parotid neoplasms.     

Surgical resection of clinically benign tumours in the maxillomandibular deep lobe of the parotid gland via sternocleidomastoid muscle–parotid space approach

This article reports the surgical resection of clinically benign tumours in the maxillomandibular deep lobe of the parotid gland via sternocleidomastoid muscle–parotid space (SPS) approach. The use of maxillary–mandibular planes to subdivide the deep lobe of the parotid gland in order to establish the tumour location and accessibility is introduced. This approach, which does not raise a skin flap, may preserve the superficial lobe. Ten patients with clinically benign tumours in the maxillomandibular deep lobe of the parotid gland were treated via the SPS approach. The patients were followed up for 3–5 years and the surgical outcomes were analysed. All tumours were completely enucleated via the SPS approach with an optimal aesthetic outcome. No permanent facial weakness or tumour recurrence was identified during the 3–5 years of follow-up. The SPS approach to surgical resection is an ideal option for clinically benign tumours in the maxillomandibular deep lobe of the parotid gland and demonstrates good results.     

Parotid function after selective deep lobe parotidectomy

Selective deep lobe parotidectomy is a demanding technique, but it preserves healthy glandular tissue, improves cosmetic results and minimises the incidence of Frey's syndrome. We have evaluated postoperative function of the superficial lobe of the parotid after selective resection of the deep lobe. Fourteen patients who each had a mass involving the deep lobe of the parotid were selected from 127 patients with tumours of the parotid gland who were seen and treated between January 2001 and March 2004. Of the 14, 12 matched the study criteria. The preoperative diagnosis was made using both computed tomography (CT) and ultrasound or fine needle aspiration cytology, and the diagnosis was confirmed by histological analysis. All cases were treated by the same surgeon. At 6 months follow-up all patients had a House-Brackmann test, iodine starch test, and scintigraphy of both parotid glands. After scintigraphy the maximum uptake value and function of the gland were evaluated with the concentration index (CI) and the CI percentage ratio. The concentration function of the gland in the resected side of the study group had a mean (S.D.) CI index of 5.5 (3.6) and a CI percentage ratio of 84%. Selective deep lobe parotidectomy has the following advantages: it minimises the impact of treatment on the facial contour, it does not increase postoperative morbidity and it preserves the function of the gland.

Pathologic and imaging findings of an oncocytoma in the deep lobe of the left parotid gland

Oncocytoma is a rare salivary gland tumour consisting of oncocytes with many hyperplastic mitochondria. It usually occurs in the parotid gland. Because the features of oncocytoma resemble those of other benign and low-grade-malignant salivary gland tumours, clinical diagnosis is often challenging. This report presents the pathologic and imaging findings of an oncocytoma arising in the deep lobe of the left parotid gland in a 66-year-old man. Oncocytoma was diagnosed on the basis of histological, magnetic resonance imaging, and scintigraphic findings. The tumour showed accumulation of technetium-99m pertechnetate and decreased signal intensity on both T1- and T2-weighted magnetic resonance images.     

腮腺浅叶多形性腺瘤两种切除术式的疗效比较

目的：对腮腺行部分切除术治疗腮腺浅叶多形性腺瘤的手术疗效经进行系统评估。方法：回顾分析2006~2010年我科诊治的128例腮腺浅叶多形性腺瘤患者,其中60例患者采用腮腺部分切除术的为A组,68例患者采用腮腺浅叶切除术的为B组,比较两组患者的手术切口长度、手术时间和术后并发症,从而判定手术疗效以及患者术后功能恢复状况。结果：与B组相比,A组患者的手术时间短,切口小,具有统计学差异（P〈0．05）,且A组患者术后各项并发症发生率低,具有统计学差异（P〈O．05）。结论：腮腺部分切除术手术创伤小、并发症少,疗效优于浅叶切除术。目前可作为治疗腮腺浅叶多形性腺瘤的较好方法。     

Lipoma of the parotid gland extending from the superficial to the deep lobe: a rarity

Lipoma of the parotid gland is a rare clinical entity. Because of the rarity, they are not often considered in the differential diagnosis of parotid tumors. Lipoma of the parotid gland constitutes around 3% of all parotid tumors. These are asymptomatic and occur both in the deep and the superficial lobe of the parotid.¹ The most favored age group is from the fifth to sixth decade of life and is 10 times more common in the males.⁶
