Abstract

Background: Facial Nerve is in close proximity with parotid gland and encountered during parotid surgery.  Facial nerve   paralysis   has   15 to 66% occurrence rate after parotidectomies. The objective of this study was to find out the frequency of facial paralysis resulting from superficial or total parotidectomies done for various parotid tumors.

Material and Methods: This retrospective study was conducted at the Department of ENT, Khyber Teaching Hospital, Peshawar from January 2018 to May 2020. A total of 203 patients were reviewed for data on demographics, parotidectomies, histopathology and facial paralysis. The information on facial paralysis was compared against various parameters.

Results:   The mean age of   the participants was 46.12 ± 11.11 years. The most common parotid tumor was pleomorphic adenoma (68.9%) followed by mucoepidermoid carcinoma. 57 (28.07%) patients showed facial paralysis with a higher rate of occurrence in total parotidectomy (40.90%). Among 57 patients with facial paralysis, 6 (10.53%) showed permanent facial paralysis.

Conclusion: Tendency of permanent facial paralysis is high with total parotidectomies. Female population and elderly have a slightly higher rate of facial paralysis. The duration of procedure has no effect on the occurrence of facial paralysis.
