A large osteoid osteoma of the mandibular condyle causing conductive hearing loss: a case report and review of literature

Osteoid Osteoma of the Basilar Border of the Mandible: A Diagnostic Dilemma

Introduction. Osteoid osteoma is a benign osseous tumor characterized by an excessive formation of unmineralized bone matrix. The aim of this study was to present, through a case report, the clinical and radiological manifestations of osteoid osteoma affecting the left basilar border of the mandible. Observation. A 30-year-old male patient presented with left mandibular pain of unknown etiology. The chief complaint was mandibular pain accentuating mainly at night, originating in the left basilar border, and radiating to the whole mandibular hemi-arch. Extraoral examination revealed a small, bone-consistent, and slightly painful swelling. Computed tomography scan revealed a well-limited, infracentimetric, and mixed osteolytic image with central nidus and peripheral osteocondensation. Histological examination revealed osteoid osteoma. Surgical excision of the lesion was performed, and the pain stopped immediately. Discussion. This benign tumor presents many clinical and radiological features similar to other lesions. To differentiate osteoid osteoma from these other bone pathoses, practitioners should have a clear concept and keen observation skills. Confrontation of the clinical, radiological, and anatomopathological data is therefore essential to establish the correct diagnosis and to determine the appropriate treatment plan.

Osteoid Osteoma of the Maxilla Presenting as Dental Implant Pain

Osteoid osteoma (OO) is a benign osteogenic lesion, regularly noticed in young individuals. A solitary lesion most frequently appears in long bones but is extremely rare in jawbones. Pain is a distinguishing characteristic of this lesion. Herein, we report a rare case of an OO in the right maxilla of a 37-year-old male presenting as pain associated with dental implants. Clinical and radiographic features were indicative of a benign neoplasia of boney origin. An excisional biopsy and histological examination of the lesion confirmed the diagnosis of osteoid osteoma. Surgical excision was followed by immediate relief of most of the pain. His follow-up visits were documented; complete relief of symptoms with no complications was observed during the postoperative period. There was no evidence of recurrence at a two-year follow-up. Osteoid osteoma of the maxilla may present as pain related to dental implants, and careful radiographic assessment of the entire jawbone should be considered if diagnosis of dental implant pain is unclear.
