minor surgical procedures, intraoperative complications, third molar.


INTRODUCTION: The extraction of the upper third molar is a simple and common procedure in Oral and Maxillofacial Surgery daily practice. Infection, facial swelling, trismus, wound dehiscence, root fracture, oroantral fistula, iatrogenic displacement, fracture of the maxillary tuberosity are some of the complications that can occur during third molar extraction.
CASE DESCRIPTION: In this article, an unusual fracture of the pterygoid process during upper third molar extraction and a minimally invasive technique for treatment are described.
CONCLUSION: It is important to recognize the fracture and not remove the fragment before a complementary image exam, it will guide the type of treatment that should be use.
