ABSTRACT
Background: In the treatment of benign parotid tumours, extracapsular dissection (ECD) and superficial parotidectomy (SP) were compared.
Aim of work; Comparing the outcomes of ECD and SP in the surgical removal of a benign parotid tumour and the rate of recurrence.
Patients and methods: This study was conducted on 100 patients with benign parotid tumours who were admitted to the general surgery department of AL-Azher university hospitals and fakus cancer centre between May 2017 and July 2020. After completing a full history and clinical examination, the patients were divided into two groups: the first 50 patients had an ECD. A benign tumour with a diameter of less than 4 cm, no deep lobe invasion, and another 50 individuals were included in the study SP was performed with a one-year follow-up to determine the rate of recurrence in both groups.
Results: The follow up period was 12 months. In terms of complain, operation time, tumour size,and recurrence the most common complain in both groups is preauricular swelling; the time of operation in ECD is 42.80±5.54 minutes compared to 127.36±16.36 minutes in SP; the tumour diameter in ECD is less than 5 cm compared to more than 5 cm in SP; the most common pathological type in both groups is pleomorphic adenoma. In SP 5 patients had disease recurrence, while in ECD, 3 patients had disease recurrence.
Conclusion: In terms of recurrence rates, conservative parotidectomy was comparable to superficial parotidectomy.
