BACKGROUND Parotidectomy was first written about by Berard in 1823 who expelled a parotid tumour of 8 years’ duration. From that point forward the methodology has been altered and applied to an assortment of considerate and harmful conditions influencing the organ. Superficial parotidectomy, subtotal parotidectomy, and total parotidectomy are presently the choices accessible to the head and neck specialist. The essential objective of parotid medical procedure is the finished expulsion of tumours while saving facial nerve. In spite of endeavours to safeguard the anatomic and utilitarian trustworthiness of the facial nerve, facial nerve loss of motion keeps on being an overwhelming difficulty of parotidectomy. We wanted to assess our involvement with parotid medical procedure, meaning to bring down the occurrence of facial nerve paralysis and concentrate on postoperative confusions. METHODS This study was conducted among 20 patients with parotid swelling of more than 1 year duration, from July 2017 to June 2019. Patients were submitted to cautious history taking, total clinical assessment, and assessment of facial nerve before medical procedure. Over a period of 2 years, these 20 patients with parotid swelling underwent parotidectomy by methods for an antegrade strategy of whom all 20 underwent superficial parotidectomy (sixteen men and four women). RESULTS All patients (20) experienced superficial parotidectomy. 11 patients had impermanent facial nerve loss of motion (55%) of whom six were HB II (30%), three were House-Brackmann Scale HB III (15%), and two were HB IV (10%). In this study, the majority of patients (9/11 patients) showed significant functional recovery within 3-6 months after surgery (median time for recovery- 6 months) and all affected patients recovered within 9 months after surgery. CONCLUSIONS In our investigation, we embraced certain safety measures to bring down the occurrence of brief facial nerve paresis. One of these safety measures is vertical withdrawal to diminish the danger of traction injury. When the nerve trunk was distinguished, we didn't utilize diathermy; haemostasis was achieved with careful ligatures (5/0 polyglactin).
