Tumour recurrence after surgical removal of parotid pleomorphic salivary adenoma using a retrograde facial nerve dissection technique

Recurrence after surgical removal of parotid pleomorphic salivary adenoma using retrograde facial nerve dissection is not well researched. We adopted retrograde nerve dissection for parotid surgery for benign disease as a standard procedure in 1995. The objective of this study was to establish the rate of recurrence of primary tumours associated with the technique after removal of parotid pleomorphic salivary adenoma. We recruited 59 patients over a 16-year (1995-2011) period and collected the data prospectively. Eight patients were excluded as they had died or had been lost to follow up. Male:female ratio was 16:35 and age range was 15-69 years. The mean tumour size as measured on magnetic resonance imaging (MRI) was 27.4mm. Thirty-eight patients had superficial parotidectomy, 8 had total parotidectomy, and 5 had partial superficial parotidectomy. Mean follow up from the date of operation was 104 months (median 98, range 17-171). All patients were reviewed and examined in 2011 to establish whether the tumour had recurred. One patient had developed a solitary nodular recurrence 8 years after the initial procedure. Recurrence was 2%. The rate of clinically apparent recurrence after parotidectomy for pleomorphic salivary adenoma in this study is low and is comparable with others reported.     

脱细胞异体真皮基质预防腮腺切除术后味觉出汗综合征和面部凹陷的临床研究

目的评价脱细胞异体真皮基质(ADM)组织补片预防腮腺切除术后味觉出汗综合征和面部凹陷畸形的临床效果。方法将50例腮腺切除术的患者随机分成组织补片组和对照组,每组各25例。组织补片组腮腺切除术后在腮腺切除创面置入ADM组织补片,对照组行常规腮腺浅叶切除术。术后1年统计2组味觉出汗综合征的主观症状及客观测定阳性例数和患者对面部外形的满意例数。结果术后1年复查时组织补片组和对照组出现味觉出汗综合征主观症状的例数分别为1例和10例,客观测定阳性的例数分别为2例和16例,2组差异均有统计学意义(P<0.01);2组患者对面部外形的满意例数分别为22例和8例;差异有统计学意义(P<0.01)。结论ADM局部应用对预防腮腺术后味觉出汗综合征及面部凹陷畸形的发生有较好的作用。     

Cervicomastoidfacial versus modified facelift incision for parotid surgery: a patient feedback comparison

INTRODUCTION

Traditionally, the cervicomastoidfacial (CMF) incision is used to excise benign tumours of the parotid gland. The rhytidectomy or modified facelift (MF) incision allows an alternative approach which leaves no visible neck scar. The objective of this study was to establish the frequency of each surgical approach used and identify any difference in complication and patient satisfaction between the two incisions for benign conditions of the parotid gland.

PATIENTS AND METHODS

A retrospective analysis of 101 case notes for patients who underwent parotidectomy by both ENT and maxillofacial departments between January 2006 and February 2008 was undertaken. All histologically confirmed cases of malignancy were excluded. For each incision, immediate postoperative complications were obtained from the notes. A postal patient outcome evaluation questionnaire sought information regarding persistent and late complications as well as a visual analogue scar satisfaction score for both incisions.

RESULTS

Overall, 79 parotidectomies were included (59 CMF incisions, 20 MF incisions). Of CMF incisions, 34% suffered facial weakness immediately postoperatively versus 20% of MF incisions. Of CMF incisions, 4% suffered postoperative haematomas versus none following MF incisions. In the study cohort, 47 (60%) responded to the postal feedback questionnaire (33 CMF versus 14 MF respondents). Information regarding immediate and late postoperative ipsilateral facial paraesthe-sia and gustatory sweating was obtained. Mean visual analogue scar satisfaction scores were 9.4 for CMF incisions and 8.9 for MF incisions.

CONCLUSIONS

Immediate and late complications for CMF and MF approaches for benign disease parotidectomy were comparable, but scar satisfaction following MF incision was not greater than CMF incisions.     

应用异种脱细胞真皮基质预防Frey综合征和面部凹陷畸形

目的:探讨异种脱细胞真皮基质降低腮腺切除术后Frey综合征及面部凹陷畸形发生率的临床效果。方法:采用随机数字表法将123例腮腺部分切除术患者分为试验组(61例)和对照组(62例),试验组腮腺切除术后植入异种脱细胞真皮基质。单盲法评价2组患者术后Frey综合征的发生情况及面部外形满意度。结果:试验组Frey综合征主、客观发生率分别为13.1%和16.4%,对照组分别为41.9%和48.4%;试验组面部外形满意度为93.4%,对照组17.7%,2组之间差异均具有统计学意义(P<0.05)。结论:使用异种脱细胞真皮基质可以有效预防Frey综合征及面部凹陷畸形,但其远期效果尚待行大样本、高质量、长期随访的随机对照。

功能性手术在治疗腮腺尾叶良性肿瘤中的临床应用

目的通过与传统术式比较,探讨功能性手术在腮腺尾叶良性肿瘤治疗中的临床应用。方法 72例腮腺尾叶良性肿瘤患者随机分为两组,传统术式组（38例）保留面神经,行肿瘤及腮腺浅叶切除术;功能性术式组（34例）行C形切口,保留面神经及耳大神经,行肿瘤及腮腺浅叶部分切除术,酌情行胸锁乳突肌瓣整复。所有患者术后随访0.5-5年,观察两组术后并发症发生率及肿瘤复发情况。结果两组患者肿瘤复发、涎漏、口干差异无统计学意义（P均〉0.05）,但两组术后暂时性面瘫、Frey综合征、耳廓区麻木感、面部凹陷畸形发生率差异具有统计学意义（P均〈0.05）。结论功能性腮腺切除术治疗腮腺尾叶良性肿瘤,术后并发症少,优于传统术式。     

Great auricular nerve conservation and parotidectomy for tumor

ObjectiveTo describe the key technical points for preserving the great auricular nerve during parotidectomy for tumor, and to discuss the literature regarding the benefits, limitations and indications for nerve-sparing surgery. Data suggested that great auricular nerve preservation should be discussed in the preoperative consultation, attempted intraoperatively and mentioned in the operative report once parotidectomy completed.     

Surgical management and side effects of parotid gland surgery for benign lesions: a retrospective analysis of our experience from 2012 to 2021

Surgery is the treatment of choice for tumours in the parotid gland. We evaluated complications following parotid surgery. We conducted a retrospective study on 554 patients undergoing parotid surgery for benign parotid tumours from 2012 to 2021. We analysed complication rates between extracapsular dissection (ECD) and superficial parotidectomy (SP). We found 19 capsular ruptures in patients undergoing ECD (5.34%) and five among those undergoing SP (2.52%) [p < 0,05]; 16 cases of temporary facial paralysis among those undergoing ECD (4.49%) and 35 in patients undergoing SP (17.67%) [p < 0,05]; and eight instances of permanent facial nerve paralysis in patients undergoing ECD (2.25%) [p > 0,05] and 13 in patients undergoing SP (6.56%). Among the mid-term complications described were: 22 salivary fistulas among patients operated with ECD (6.18%) [p > 0,05] and 17 in patients with SP (8.58%) 17 sialoceles in those who underwent ECD (4.77%) and seven with SP (3.53%) [p > 0,05]. Regarding late complications, we found: surgical wound dehiscence, pathological scarring (keloid), Frey's syndrome, and recurrence, which affected 45 patients with ECD (12.64%) and 21 with SP for dehiscence (10.6%) [p < 0,05]; 28 keloids in patients with ECD (7.86%) and 15 in patients with SP (7.57%) [p > 0,05]; 12 cases of Frey's syndrome in patients with ECD (3.37%) and 36 with SP (18.18%) [p < 0,05]; and finally 22 recurrences in patients who underwent ECD (6.18%) and 13 in patients who underwent SP (6.56%) [p > 0,05], including 30 in the 273 patients with pleomorphic adenoma and five in the 214 patients with Warthin’s tumour. We can conclude that the onset of the different complications after parotid gland surgery are related to the surgery performed. Our data confirm that there is a tight relationship between type of surgery performed and type of complication.
