Osteoma is a benign tumor that occurs from the proliferation of cancellous bone, compact bone, or their combination... A mass was coincidentally detected 2 years prior to presentation during orthodontic examination on panoramic radiography, which was the reason she was aware that she had an asymmetrical left mandible... The size of the mass had gradually increased since then, so the patient was admitted to our hospital for removal of the mass and reduction angloplasty for aesthetic purposes... The patient had a history of contusion on the left mandible from a bicycle accident 12 years prior and explained that she had experienced a hematoma for several weeks at that time... A physical examination showed that the mass was asymptomatic and had a well-defined circular shape, which was firmly fixed on the left mandibular angle region... The skin color around the lesion was normal, and the skin did not adhere to the mass (Fig. 1)... As for radiological evaluation, a skull anteroposterior view was obtained, and a solitary oval, well-defined, radiopaque mass was observed (Fig. 2)... Under general anesthesia reduction angloplasty was performed by performing a resection inside the mouth... On the postoperative biopsy, an exophytic osteogenic tumor composed of cancellous trabecular bone was observed, and the pathologic diagnosis was osteoma (Fig. 4)... The patient wore a compressive garment for 10 days... No specific side effects or complications occurred... First, the developmental theory suggests that peripheral osteomas result from developmental abnormalities, but this is not convincing because most patients have passed their growth phase... As osteomas can induce clinical symptoms such as facial asymmetry and pain, clinicians must carefully conduct physical examinations during patients' preliminary medical examination... Diagnosis can be made according to the results of preoperative evaluation and appropriate imaging tests, which can be the foundation for surgical planning.

Mentions: A physical examination showed that the mass was asymptomatic and had a well-defined circular shape, which was firmly fixed on the left mandibular angle region. The skin color around the lesion was normal, and the skin did not adhere to the mass (Fig. 1).
