# Application of 3D technology for the design of a guidewire for deep cervicofacial collections percutaneous management

## TL;DR

This paper describes a new method using 3D technology to create a custom guide for safely draining deep facial abscesses with minimal invasiveness.

## Contribution

The novel use of CAD-CAM and 3D technology to design a puncture guide for CT-guided drainage in cervicofacial abscesses.

## Key findings

- The custom 3D guide enabled precise drainage without damaging critical structures.
- The patient experienced rapid improvement and shorter hospitalization.
- The method is less invasive and beneficial for high-risk patients.

## Abstract

This study aims to present a case of deep cervicofacial abscesses and demonstrate the efficacy of CT-guided drainage with a custom-designed puncture guide in a challenging anatomical location. The use of this type of guide is an innovative technique since CAD-CAM technology has not been used for this type of application until now.

A 76-year-old man with persistent facial swelling and trismus underwent surgical drainage initially, but symptoms persisted. A CT-guided transcutaneous approach was planned using a custom-designed positioning guide created with “in-house” 3D technology. The guide was fabricated using Surgical Guide resin, and the patient underwent successful CT-guided drainage.

The intervention facilitated precise drainage without damaging critical anatomical structures. The patient exhibited prompt clinical improvement, shortened hospitalization, and favorable aesthetic outcomes.

CT-guided drainage, particularly when combined with a custom puncture guide, offers a less invasive alternative for challenging cervicofacial abscesses. This approach proves valuable in reducing procedure duration, minimizing soft tissue trauma, and enhancing preoperative planning, making it especially beneficial for patients with high anesthetic risk or complex anatomical considerations.
