Summary
Coronoid hyperplasia, a rare condition, was observed in two brothers, suggesting a potential familial link. Surgical outcomes varied, with one brother experiencing successful treatment via coronoidectomy.
Area of Science:
- Oral and Maxillofacial Surgery
- Medical Genetics
Background:
- Coronoid hyperplasia is a rare condition affecting the mandibular coronoid process, often undiagnosed without imaging.
- The etiology is unknown, but familial inheritance has been suggested.
Observation:
- This study details two brothers diagnosed with coronoid hyperplasia.
- Both brothers presented with enlarged coronoid processes, confirmed by panoramic radiographs and CT scans.
- One brother experienced impingement of the coronoid process against the zygomatic bone.
Findings:
- The affected brothers suggest a possible familial or genetic component to coronoid hyperplasia.
- Surgical intervention outcomes differed: unilateral intraoral coronoidectomy was successful, while bilateral surgery was not.
Implications:
- This case highlights the importance of radiographic diagnosis for coronoid hyperplasia.
- The findings contribute to understanding the potential hereditary nature of this condition.
- Varied surgical outcomes suggest further research into optimal treatment strategies is warranted.
