Diagnosis and Management of Craniofacial Osteomas.

IMPORTANCE: Osteoid osteomas are benign bony overgrowths that can occur in any region of the body. However, they have a predilection to occur in the craniofacial region. Because of the rarity of this entity, there is a lack of literature detailing the management and prognosis of craniofacial osteoid osteomas. OBSERVATIONS: Craniofacial osteomas have a predilection to involve the paranasal sinuses, but can also be found within the jaw, skull base, and facial bones. Because of their slow-growing nature, craniofacial osteomas are often incidentally discovered on routine imaging or after they compress nearby structures or distort nearby anatomy. Osteoid osteomas of the face can be treated with resection via various approaches. Recent advancements describe minimally invasive endoscopic techniques and adjuvant therapy with radiofrequency ablation guided by cone biopsy computed tomography. Osteoid osteomas have an excellent prognosis with complete resection. They demonstrate a low incidence of recurrence when compared with other osteoblastic lesions of the craniofacial structures. CONCLUSIONS AND RELEVANCE: Craniofacial osteoid osteomas remain a developing topic within the field of craniofacial surgery. Their removal may be trending toward minimally invasive techniques. However, all treatment modalities appear to result in improved cosmetic outcomes and low recurrence rates.

Piezosurgery for Excision of Large Osteoid Osteoma.

Osteoid osteoma, a rare benign osteoblastic tumor first described by Jaffe in 1935, is characterized as a small but painful lesion that mostly affects younger people. Usually benign and harmless, osteomas are removed for pain or esthetic reasons.Piezoelectric surgery is also increasingly being used effectively in major and minor osseous oral and maxillofacial surgeries, in delicate areas. It is used regularly for various procedures, including sinus lift procedures, bone graft harvesting, osteogenic distraction, ridge expansion, inferior alveolar nerve decompression and lateralization, cyst removal, dental extraction, and impacted tooth removal.The following report presents a patient of intraoral excision of a large osteoid osteoma from lingual aspect of mandibular lower border in the body region using piezoelectric surgery.

Cancellous osteoma of the maxillary tuberosity: case report.

The osteoma is a benign, bone-forming lesion that is not considered a true neoplasm. It almost exclusively affects the flat bones of the skull and face. Jaw lesions may cause facial deformity and impair oral function. Multiple osteomas may be associated with Gardner's syndrome. Clinically and radiographically, osteomas may need to be differentiated from other bone-forming lesions. This article describes a cancellous osteoma of the left maxillary molar and tuberosity area and differentiates it from other benign and malignant lesions, including the parosteal osteosarcoma.

[Image-guided ablation of bone tumors: review of current techniques]. / Ablation des tumeurs osseuses sous contrôle de l'imagerie: revue des techniques actuelles.

Multiple interventional radiology techniques are available for percutaneous ablation of bone tumors: alcohol, laser, radiofrequency, microwave, ultrasound, and cryogenic ablation. Several indications have already been validated, including radiofrequency ablation of osteoid osteoma and bone metastases, with results superior to conventional treatment. More indications should be added over the coming years. The purpose of this article is to review the principles of the different ablation techniques, summarize their respective indications and results and discuss their implementation and the eventual combination with cementoplasty techniques.

Osteoma of the mandible: case report and application of multi-detector-row CT rendering technique.

Osteoma is an uncommon benign slow growing neoplasm of the bone, characterized by proliferation of osteoblasts forming bone trabeculas in a connective tissue stroma. After paranasal sinus, mandible is its second most frequent location. The osteoma can be central, peripheral or of extraskeletal type. Peripheral osteomas are quite uncommon. This fact suggests that peripheral osteoma of the mandible may be traumatically damaged, mostly because of muscle traction. This paper reports a case of peripheral osteoma located in the mandible. The patient underwent a multi-detector-row computed tomography (MDCT) in order to plan corrective surgery. MDCT images were post-processed with volume rendering techniques.

Osteoid osteoma of the zygoma: report of an unusual case.

BACKGROUND: Osteoid osteoma is a benign tumor of bone characterized by pain, usually occurring at night, that shows a dramatic response to aspirin. The literature contains reports of only a few cases in the head and neck region. CASE DESCRIPTION: The authors present an unusual case of an osteoid osteoma of the craniofacial bones. The patient sought an evaluation of pain in the area of the right zygoma. One of the authors, an oral and maxillofacial surgeon, noted a small area of swelling. The patient underwent radiographic, computed tomographic and nuclear medicine studies. On the basis of the images and the biopsy report, the authors made a diagnosis of osteoid osteoma. In this article, they describe the treatment of and new modalities of therapy for this condition. CLINICAL IMPLICATIONS: The general dentist should be aware of any lesion that is not common. If the generalist has any doubt about the nature or management of an unusual oral lesion, referral to appropriate specialists is mandatory.

Chronic temporomandibular joint pain: two cases of osteoid osteoma and a review of the literature.

Osteoid osteoma is a benign bone tumour with self-limiting growth potential occurring in any part of the body. Two rare cases of a pathologically proven osteoid osteoma invading the temporomandibular joint (TMJ) are reported herein. This article also reviews the cases of osteoid osteoma of the craniofacial complex reported in the English-language literature to date. Although the clinical presentation of osteoid osteoma in the jaw differs from that of osteoid osteoma in the more common locations, the radiographic features are similar. In both cases presented, computed tomography revealed a small round osseous lesion with sharp margins in the TMJ. Bone scintigraphy was performed in order to differentiate the lesions from other osseous lesions. Both patients underwent surgical excision of the lesion with immediate relief of the pain. The importance of early recognition of the clinical and imaging characteristics of an osteoid osteoma of the TMJ is emphasized, in order to prevent misdiagnosis and avoid discouraging therapies.

[Osteoid osteoma of zygomatic bone: Case report and literature review]. / Ostéome ostéoïde du corps de l'os zygomatique : à propos d'un cas et revue de la littérature.

INTRODUCTION: Osteoid osteoma is a benign osseous tumor affecting mainly young men. Although it develops essentially in long bones, some cases occurring in face, mainly in mandible, were related. To our knowledge, only one single case was described in zygomatic bone. OBSERVATION: A 71-year-old man consulted for a right periorbital pain evolving since months with night recrudescence. The pain was not relieved by standard analgesics. Clinical examination was strictly normal. CT scan showed a low-density bone lesion surrounded by a peripheral osseocondensation line within the body of the right zygoma with intense uptake at bone scintigraphy. The patient benefited from surgical excision of the lesion. Pain stopped immediately. Histological examination assessed an osteoid osteoma. DISCUSSION: Zygomatic localization and late occurrence are rare concerning osteoid osteomas. Many ways of management have been reported but surgical excision remains the gold standard.

Repair of major cranio-orbital defects with an elastomer-coated mesh and autogenous bone paste.

We present a method for repairing defects in the craniofacial region in which an elastomer-coated mesh is used as a template with bone paste. The method was developed by animal experimentation first, and then successfully used in the maxillofacial and mandibular regions. We have used this method to repair 16 craniofacial defects with satisfactory results, and complications have been kept to a minimum.

Maxillectomy in childhood.

A maxillectomy in the upper part of the maxilla is an uncommon operation in childhood. The authors comment on the clinical evolution, the related pathologies and the surgical techniques employed in the treatment of eight patients.

Osteoid osteoma in mandibular condyle.

A 21-year-old Japanese woman presented with trismus and spontaneous pain (especially at night) around the left temporomandibular joint. Radiographic examination showed a subcortical sclerosed nodule measuring approximately 8 mm in diameter on the infero-lateral aspect of the left mandibular condyle. Amputation of the condyle was performed under general anesthesia. The patient has been in good condition 8 years postoperatively. The histopathology of the specimen consisted of actively proliferating osteoblasts mixed with an interlacing network of woven bone and osteoid trabeculae. Histopathological diagnosis was osteoid osteoma.

Osteoid osteoma associated with the teeth: unusual presentation.

Osteoid osteoma is a rare benign osseous neoplasm which rarely affects the jaws. It is more common in long bones which can lead to postural scoliosis. The clinical characteristic feature of this tumour is the unexplained pain that is relieved by the intake of analgesics. Histologically it is characterized by the formation of central nidus with surrounding sclerotic bone. The diagnostic dilemma in this case report is aggravated by its unusual association with the teeth. The use of CT scanning is advised to distinguish from other odontogenic tumours. Treatment for this tumour is surgical removal or excisional biopsy to avoid recurrence and progression to malignant changes.
