Exostoses are pathological bone growths located uni- or bilaterally, most frequently in the palatal midline, or lingually in the mandible. As they increase in size, they may create difficulties when removable prosthetic restorations are constructed or used. Their aetiology has not been fully explained. It is believed that their initiation is related to chronic inflammatory conditions in the bone tissue or its immediate vicinity. Exostoses may gradually increase in size as they are being stimulated during chewing. The lesions are composed of bone tissue and thus they can be visualized radiographically as radiopacities having the same structure as the surrounding bone with no visible demarcation. Most of the exostotic lesions do not require treatment and can be subject to observation. Otherwise, the therapeutic procedure is only surgical. As is the case with all hyperplastic lesions, exostoses should be differentiated with benign and malignant neoplasms. The final diagnosis is always based on histopathological examination. Surgical removal of mandibular exostoses localized lingually may be a vital element in the management of sleep apnoea.
