Comparative Study Between Superficial Parotidectomy and Extracapsular Resection in Benign Parotid Tumor

Abstract

Background: The purpose of this study was to gather evidence supporting the use of a more suitable method out of extracapsular resection and superficial parotidectomy for benign parotid tumors with minimal postoperative complications.

Objective: To compare the outcome of superficial parotidectomy and extracapsular resection in benign parotid tumor.

Subjects & Methods: This was a quasi-experimental study carried out at surgical unit II of Jinnah Hospital, Lahore from February, 2024 to February 2025. A total of sixty patients who met the specified criteria were segregated equally into two groups. Patients in group A had superficial parotidectomy while patients in B group had extracapsular resection. The duration of the operation was recorded. The patients underwent follow-up visits in the outpatient department (OPD) after 3 and 6 months to observe for facial nerve palsy and recurrence. The data was inputted and analysed using SPSS version 25.0. Appropriate tests were applied for determine the statistical significance.  A significance level of p < 0.05 was used to determine statistical significance.

Results: In group-A, 18(60.0%) patients were males and 12(40.0%) were females, while in group-B, 19(63.3%) patients were males and 11(36.7%) were females. Age range in this study was from 20 to 70 years. The mean age of patients in group-A was 53.43 years and 52.77 years in group-B. The mean BMI of patients in group-A was 28.5 kg/m2 and 28.7 kg/m2 in group-B. The mean duration of disease in group-A was 8.5 months and 8.7 months in group-B. In group-A (Extracapsular resection), 3(10.0%) had facial nerve palsy and 7(23.3%) in Group-B (Superficial parotidectomy).

Conclusion: Extracapsular resection emerges as a feasible approach for the management of superficial benign parotid gland tumours in terms of post-operative facial nerve palsy, recurrence, neuropraxia, wound infection, bleeding and pain.
