Summary
Coronoid process hyperplasia caused restricted jaw opening and facial asymmetry. Advanced imaging confirmed this rare anatomical variation before surgery.
Area of Science:
- Oral and Maxillofacial Surgery
- Radiology
- Anatomical Variations
Background:
- Coronoid process hyperplasia is a rare condition characterized by an enlarged coronoid process of the mandible.
- It can lead to significant functional limitations, including restricted mouth opening (trismus).
- Facial asymmetry may also be a presenting sign, often overlooked.
Observation:
- A case is presented with a primary complaint of limited jaw opening.
- Marked facial asymmetry was noted in the right zygomatic region.
- The patient presented with symptoms suggestive of coronoid process hyperplasia.
Findings:
- Presurgical documentation utilized routine radiography and computed tomography (CT) with sagittal reconstruction.
- CT imaging clearly delineated the enlarged coronoid process and its impact on mandibular motion.
- Radiographic findings correlated with the clinical presentation of restricted opening.
Implications:
- Accurate presurgical diagnosis of coronoid process hyperplasia is crucial for effective treatment planning.
- Advanced imaging techniques like CT are essential for characterizing this anatomical variation.
- Understanding this condition aids in managing temporomandibular joint disorders and improving patient outcomes.
