Summary: | A 28-year-old male presented to the hospital with swelling of the left zygoma, severely limited mouth opening and pain. There was no history of trauma or congenital bone disorder. Computed tomography revealed an enlargement of the coronoid process of the mandible. The diagnostic hypothesis was osteochondroma so the patient was submitted to surgery under general anesthesia via naso-tracheal intubation for lesion excision. Al-Kayat and Bramley's preauricular incision was performed. After dissection, the zygomatic arch was removed to access the lesion. The tumor and the coronoid process were visualized and removed without difficulty and the zygomatic arch was repositioned and fixed with plate and screw. The specimen was sent for anatomopathological analysis, which revealed the presence of a fibrocartilaginous cap with mononuclear hypertrophic condrocytes within trabecular bone. Postoperatively, the patient was able to open his mouth properly and is on regular follow-up with no signs of abnormalities. |
