Association with infection, pain, pressure, pulsation, swelling, facial asymmetry, headache, ocular pain, tinnitus, otalgia, epistaxis, toothache and/or teeth mobility and compressibility into their sockets is possible, although it may also be asymptomatic."

Lesions may be asymptomatic or may manifest with pain, ulceration, pulsation, tinnitus, minor bleeding or potentially life-threatening hemorrhage, blurred vision, impaired hearing, headache, paresthesia, enlargement of facial bones with intraosseous lesions, intraosseous hemangiomas, and speech, breathing and swallowing difficulties, as well as neuropathy."
