Clinical and radiological findings of a bilateral coronoid hyperplasia case

Kubra Torenek et al. Eur J Dent. 2015 Jan-Mar.

Abstract

Coronoid hyperplasia (CH) is an infrequent condition that can be defined as an abnormal bony elongation of histologically normal bone. Progressive and painless difficulty in opening the mouth is the main clinical finding of CH. In this case report, the clinical and radiological findings for a 23-year-old male patient with bilateral CH are presented. When plain radiographies are not sufficient for diagnosis and evaluation of the CH, cone-beam computed tomography can be used.

Keywords: Cone-beam computed tomography; coronoid enlargement; coronoid hyperplasia.
