Abstract

Background

Mandibular coronoid hyperplasia is a rare condition associated with gradual reduction in mouth opening. Its aetiology is unknown but increased temporalis activity, endocrine stimulus, trauma and familial causes have been proposed.

Case report

In this article, we present a case of bilateral coronoid hyperplasia presenting with limited mouth opening in 16-year-old Caucasian twin sisters.

Discussion

This report gives a new perspective to the aetiology of coronoid hyperplasia since it describes its occurrence in monozygotic twins and hence provides a strong argument in support of a genetic aetiology.
