Osteoid osteomas are benign skeletal neoplasms that are commonly encountered in the bones of the lower extremities, but are exceedingly rare in jaw bones with a prevalence of less than 1%. This unique clinical entity is usually seen in younger individuals, with nocturnal pain and swelling as its characteristic clinical manifestations. The size of the lesion is rarely found to be more than 2 cm. We hereby report a rare case of osteoid osteoma originating from the neck of the mandibular condyle that grew to large enough proportions to result in conductive hearing loss in addition to pain, swelling and restricted mouth opening. In addition, an effort has been made to review all the documented cases of osteoid osteomas of the jaws that have been published in the literature thus far.
