"Unraveling the Tapestry": A Retrospective Exploration of Recurrent Parotid Pleomorphic Adenoma Cases.

The standard surgical procedure for treating the parotid gland's recurrent pleomorphic adenoma (RPA) is parotidectomy with facial nerve preservation (FN). Treatment of RPA remains challenging since controversies occur regarding recurrence, degree of revision surgery, postoperative radiation, and difficulty in conserving the FN. A retrospective review of patient's medical records treated for benign parotid neoplasms was conducted between 2017 and 2022 to identify individuals who underwent surgery for RPA. Demographic information, surgical intervention details, pre-and postoperative facial nerve function, histopathological analysis, and recurrence rates were collected. These variables were compared in patients with single recurrent tumors versus patients with multiple recurrent tumors. Twenty-one patients met the criteria, including 13 with a first recurrence, 7 with a second recurrence, and 1 with a third recurrence. Following surgery for multiple RPA, long-term FN outcomes were significantly worse ( = 0.005). There were no observable risk factors for tumor recurrence. The interval between the initial revision surgery and subsequent ones was drastically shortened. Our study suggests that the risk of permanent facial paralysis is greater with subsequent surgical procedures. Early detection of recurrence can aid in early re-operation.
