# Computer-Aided excision of Parapharyngeal Space Pleomorphic Adenoma by Transcervical Approach. Case report

## TL;DR

This case report describes the successful surgical removal of a rare neck tumor using 3D planning software and a cervical approach.

## Contribution

The paper demonstrates the effective use of 3D navigation software for preoperative planning in a challenging surgical area.

## Key findings

- A transcervical approach allowed safe tumor excision without damaging vital structures.
- 3D technology improved understanding of tumor-anatomy relationships for better surgical outcomes.
- The cervical approach is suitable for benign parapharyngeal tumors when carefully planned.

## Abstract

The parapharyngeal space, situated in the neck’s lateral part, poses challenges for surgical intervention due to its complex anatomy. Tumors in this space are rare, accounting for 0.5-1% of head and neck tumors, often remaining asymptomatic until reaching substantial sizes.

This article outlines the surgical management of such lesions using navigation software, illustrated through a clinical case. A 38-year-old male presented with a mass at the right mandibular angle. Preoperative planning with Brainlab iPlan CMF® software aided in understanding the tumor’s relationship with adjacent structures. A transcervical approach facilitated tumor excision without damaging vital anatomical structures. Histopathology confirmed pleomorphic adenoma.

The paper underscores the rarity of parapharyngeal tumors, the importance of individualized surgical strategies, and the utility of 3D technology in preoperative planning for enhanced anatomical understanding.

The cervical approach remains a satisfactory choice for benign lesions in this challenging space.
