BACKGROUND/AIM: Tumours of the parotid gland are not common. Parotid tumours can pose a challenge both in diagnosis and treatment. Various factors contribute to the management difficulties of parotid tumours for the Head neck surgeon. The aim of the study is to determine the presentation and management of parotid tumours requiring surgery at the Burns and Plastic and Otolaryngology (ORL) units of the hospital.
This is a retrospective study carried out at the Lagos University Teaching Hospital from January 1994- December 2005. The medical case notes were reviewed for information on age, sex, clinical presentation, surgical management, histological diagnosis and outcome.
A total of 58 patients with parotid tumours were seen with ages ranging from 25-65 years. Male to Female ratio was 1.4:1. Forty-two (72.4%) presented with firm preauricular swelling, 1.7% as dumb bell tumour and post surgical recurrence tumour respectively, 6.8% as tail of parotid tumour and 3.5% as bilateral disease. 93.13% had superficial parotidectomy. Histological diagnosis confirmed 65.5% as pleomorphic adenoma, 20.72% as carcinomas of which adenoidcystic and mucoepidermoid tumours were the commonest,3.45% as lymphoma and 1.7% as Sjogrens syndrome, oxyphil and Warthins tumour respectively. Immediate post surgical facial nerve palsy was seen in 69% and recovery was seen in 62% within 3-9months. Post surgical radiotherapy was given to 8.6%.
The commonest parotid salivary gland tumour requiring surgery is pleomorphic adenoma, presenting as a pre-auricular mass and the commonest post- surgical complication was facial nerve palsy involving the mandibular branch. A good knowledge of the surgical anatomy of the gland, clinical behaviour and biologic nature of the tumours will ensure better surgical management.
背景/目的：腮腺肿瘤并不常见。腮腺肿瘤在诊断和治疗方面都可能构成挑战。多种因素导致头颈外科医生在处理腮腺肿瘤时面临管理困难。本研究的目的是确定在该医院烧伤整形科和耳鼻喉科（ORL）需要手术治疗的腮腺肿瘤的临床表现及治疗情况。
这是一项于1994年1月至2005年12月在拉各斯大学教学医院开展的回顾性研究。查阅医疗病历以获取有关年龄、性别、临床表现、手术治疗、组织学诊断及结果的信息。
共诊治58例腮腺肿瘤患者，年龄在25至65岁之间。男女比例为1.4:1。42例（72.4%）表现为耳前硬性肿胀，分别有1.7%表现为哑铃状肿瘤和术后复发肿瘤，6.8%表现为腮腺尾部肿瘤，3.5%表现为双侧病变。93.13%的患者接受了浅叶腮腺切除术。组织学诊断证实65.5%为多形性腺瘤，20.72%为癌，其中腺样囊性癌和黏液表皮样癌最为常见，3.45%为淋巴瘤，1.7%分别为舍格伦综合征、嗜酸性细胞腺瘤和沃辛瘤。69%的患者术后立即出现面神经麻痹，62%在3至9个月内恢复。8.6%的患者接受了术后放疗。
需要手术治疗的最常见腮腺唾液腺肿瘤是多形性腺瘤，表现为耳前肿块，最常见的术后并发症是累及下颌支的面神经麻痹。熟悉腮腺的手术解剖结构、肿瘤的临床行为和生物学特性将确保更好的手术治疗效果。
