Minimally invasive extracapsular dissection of pleomorphic adenoma of the parotid gland: a 4 years study at Rehman Medical Institute Peshawar

Abstract

Introduction: The most common benign tumour of salivary glands is known as Pleomorphic adenoma (PA). Minimally invasive extracapsular parotidectomy is becoming more common for this tumor.

Objective: To provide an insight into the newer modality in Parotid gland surgery which is not a common ground of practice in Pakistan.

Materials & Methods: This study was conducted at the Otolaryngology/Head & Neck surgery department of a tertiary care hospital of Peshawar. Records of patients from July 2016 till March 2021 for cases diagnosed as “pleomorphic adenoma of parotid and submandibular glands” were retrieved, their corresponding patient files accessed from the archive, and case notes analyzed using Microsoft Excel. Subsequent to discharge, follow up visit after one week was done for all 16 patients. Data were analyzed for descriptive statistics.

Results: In this series of 16 cases of pleomorphic adenoma treated by extracapsular parotidectomy, males were predominant (62.5%). Right side (75.0%) predominance was also observed for the tumour location. Only one case (6.25%) developed a small collection of seroma while all the others did not show any complications. Regular follow-ups have not shown recurrence of the tumour.

Conclusion: The recommended treatment of pleomorphic adenoma is surgical removal of the entire tumour with a cuff of normal tissue. The minimal invasive extra capsular parotidectomy procedure showed minimal complications and recurrence rate was negligible in 4 years of follow up.
