Pleomorphic Adenoma of Parotid Gland and Facial Nerve Dysfunction Post Superficial Parotidectomy: A Case Report

Background: Pleomorphic Adenoma is the most prevalent salivary gland neoplasm accounting for about two-thirds of all salivary gland tumours. The facial nerve and branches are closely related to the parotid gland, hence facial nerve preservation and monitoring during parotidectomy is of paramount importance to avoid facial nerve injury. Case Description: A case of pleomorphic adenoma of the parotid gland in a 49-year-old female patient with subsequent facial nerve dysfunction after superficial parotidectomy is presented in this report. The objective of the case report is to highlight the importance of meticulous facial nerve dissection and intraoperative facial nerve monitoring to avoid facial nerve dysfunction postoperatively. Conclusion: Facial nerve dysfunction after surgery of pleomorphic adenoma is still an encountered complication of parotidectomy. Therefore, meticulous facial dissection, follow up of patient after facial nerve injury and facial nerve rehabilitation techniques should be practiced.
