Buccal Exostosis

Buccal exostosis on the upper jaw

A buccal exostosis is a benign bony growth located on the buccal surface of the jaw. These growths are typically found on the outer side of the upper or lower jaw, near the cheeks. Buccal exostoses are generally asymptomatic and are often discovered incidentally during routine dental examinations.

Etiology

The exact cause of buccal exostosis is not well understood. However, it is believed to be influenced by genetic factors, as well as environmental factors such as bruxism (teeth grinding) and other forms of chronic irritation or stress on the jawbone. Some studies suggest a possible link to periodontal disease or other inflammatory conditions of the oral cavity.

Clinical Presentation

Buccal exostoses are typically hard, bony protrusions that can vary in size. They are covered by normal oral mucosa and are usually painless. In some cases, they may cause discomfort if they interfere with denture placement or if they become ulcerated due to trauma.

Diagnosis

The diagnosis of buccal exostosis is primarily clinical, based on the characteristic appearance and location of the bony growths. Radiographic imaging can be used to confirm the diagnosis and assess the extent of the exostosis.

Treatment

In most cases, buccal exostoses do not require treatment unless they cause significant discomfort or interfere with oral function. Surgical removal may be considered if the exostosis affects prosthetic appliance fitting or if there is recurrent trauma to the overlying mucosa.

Prognosis

The prognosis for individuals with buccal exostosis is excellent, as these growths are benign and do not transform into malignant lesions. Recurrence after surgical removal is rare.
