Partial Superficial Parotidectomy: An Effective and Conservative Approach for Pleomorphic Adenoma

Partial Superficial Parotidectomy

Abstract

Background: To avoid high recurrence associated with enucleation due to the histological structure of pleomorphic adenoma, a complete superficial Parotidectomy approach with increased morbidity was adopted, which has become the gold standard even up till now for tumors of the superficial lobe. This study was designed to evaluate the effectiveness of the conservative approach of partial superficial Parotidectomy in terms of recurrence and facial nerve injury for treatment of pleomorphic adenoma. Objective: To compare the standard superficial Parotidectomy with partial superficial Parotidectomy in terms of recurrence and facial nerve injury. Study Design: Experimental study. Settings: Department of Surgery, DHQ Hospital, Rawalpindi Pakistan. Duration: 01-02-2018 to 30-01-2019. Methods: After taking written informed consent, a total of 21 (N=21) patients were included in this experimental study according to the selection criteria by probability sampling and divided into two groups by the Lottery method. Patients were followed for a period of one year for recurrence. SPSS-22 did data analysis. The p-value was set at 0.05. Pearson correlation was used for statistical significance. Results: There were 66.67% males and 33.34% females. The mean tumor size was 2.45 cm ± 0.289 with a 2-2.9 cm range.  In group 1 (n=9), transient facial nerve injury occurred in 1 patient, whereas in group 2 (n=12), it occurred in 3 patients. No recurrence was found in either group. Conclusion: Partial superficial Parotidectomy is an effective and conservative surgical approach for pleomorphic adenoma of the parotid gland. The recurrence rate in this approach is comparable with conventional superficial Parotidectomy, whereas the rate of facial nerve injury is significantly reduced.
