# Subcutaneous Emphysema of Periorbital and Canine Space Following Endodontic Treatment

## TL;DR

A rare case of facial swelling and air in tissues after a dental procedure is reported, highlighting a uncommon but manageable complication.

## Contribution

The paper reports a novel case of subcutaneous emphysema following endodontic treatment in a specific facial region.

## Key findings

- Subcutaneous emphysema occurred in the periorbital and canine space after endodontic treatment.
- The condition was localized and did not lead to severe long-term health issues.
- The case highlights the potential for air-driven dental tools to cause such complications.

## Abstract

Emphysema of the subcutaneous tissue is an uncommon complication of dental procedures. Certain dental surgical procedures, such as extraction of teeth using air-driven handpieces and endodontic procedures are more prone to cause subcutaneous emphysema. Subcutaneous emphysema is typically self-limiting and only in a few instances has an impact on the long-term health of the patient. Patients with subcutaneous emphysema experience pain, distress and inconvenience. This paper presents a case of subcutaneous emphysema of the right canine and periorbital space following endodontic treatment of the upper right front tooth.
