Bilateral hyperplasia of the coronoid processes of the mandible is an uncommon condition that has been reported in 24 patients.1-3 The coronoid processes are usually normally shaped,4,5 and have been classically described by Shira and Lister as "mere overgrowths of bone."6 The process has been diagnosed as a developmental hyperplasia, and the etiology has remained unknown.1,2,5,7 The most common symptom of bilateral coronoid hyperplasia is limitation of mandibular opening without visible facial deformity.1-3,5,8 The previously reported cases of bilateral coronoid hyperplasia have all been reported in males.1-3 This has led some authors to speculate that the condition is sex-linked. This paper describes two new cases, one being the first reported in a female.
