Introduction
Hyperplasia of the coronoid process of the mandible is a rare developmental anomaly and my be unilateral or bilateral.
Unilateral enlargement of the coronoid process can result from a true tumor,such as an osteochondroma or osteoma.
The purpose of this case report is its abnormal sits as well as rarity.
Results and discussion
An enlarged coronid process impinging on the posterior surface of the zygoma restricting mandibular opening and facial asymmetry and fracture of zygomatic arch was detected.
Coronoidectomy was done for the patient under general anesthesia via an intraoral approach.
Conclusion
One of the differential diagnosis of restricted mandibular opening is coronoid process hyperplasia. Treatment of coronoid hyperplasia consists of surgical removal of the
enlarged coronoid process or processes to allow freedom of mandibular motion. Coronoidectomy is usually accomplished via an intraoral approach.
Conventional radiographic techniques do not fully reveal the size and mushroom-shaped coronoid process, so CTScanning and tomography is suggested.
