Bilateral Hyperplasia of the Coronoid Process of the Mandible: Report of a Case

Computed tomography in the investigation of bilateral mandibular coronoid hyperplasia

“…Two-dimensional axial CT scanning has been used to confirm a diagnosis of bilateral coronoid hyperplasia [7] and to demonstrate the impingement of the hyperplastic coronoid process against the posterior surface of the zygomatic arch on opening [14,15]. As this report illustrates, three-dimensional CT reformation yields more comprehensive spatial information and obviates the need for three-dimensional mental reconstruction.…”

“…The coronoid processes are often symmetrical and generally uniform, but hooked anterior curvature of the distal aspects has been reported [6,7]. Histologically, the condition is one of hyperplasia rather than neoplasia.…”
