Abstract

The surgical management of benign parotid tumors is aimed at complete extirpation of the mass with preservation of facial nerve function. There is a relative paucity of literature pertaining to complications after benign parotid surgery and related risk factors. We aim to critically review the outcomes following treatment of benign parotid pathology when surgery entailed either complete superficial parotidectomy (CSP), partial superficial parotidectomy (PSP) or extracapsular dissection (ECD).This is a review of prospectively collected data of all parotidectomies performed between June 2006 to June 2016 for histologically-proven benign pathology of the parotid. Median follow-up time was 31.6 weeks.A total of 101 parotidectomies were carried out on 97 patients (40 CSP, 56 PSP and 5 ECD). Pleomorphic adenoma (48.4%) and Warthin's tumors (32.7%) were the most common pathologies. Temporary facial weakness occurred after 7 operations (6.9%). Facial weakness was permanent in 4 cases (3.9%). The rates of sialocele and salivary fistula were 4.9% and 0.9%, respectively. Only one patient (0.9%) developed Frey Syndrome postoperatively. No significant associations between extent of parotid surgery and postoperative facial nerve dysfunction (p = 0.674) or wound complications (p = 0.433) were observed. Univariate analyses for potential contributing factors such as advanced age, smoking status, tumor location or histology did not demonstrate any increased risk with developing postoperative complications.Partial superficial parotidectomy was associated with low rates of morbidity to the facial nerve and surgical wound. The results were comparable to complete superficial parotidectomy. We recommend offering patient partial superficial parotidectomy where appropriate and this is in line with the current trend of minimising surgical dissection, thereby potentially decreasing the risk of short-term and long-term complications.
