Endoscopic-assisted resection of peripheral osteoma using piezosurgery

Life-threatening mandibular angle gigantic osteoma presenting with severe dyspnoea

Osteoma is a benign osteogenic tumour. Solitary osteoma of the jaws usually involves the mandible and commonly remains asymptomatic. Purpose of this article is to report a case of life-threatening gigantic mandibular osteoma in an edentulous woman in her 70s developed in the lingual side of the mandibular angle presenting at emergency department with dyspnoea and discuss the correct management of the patient and the surgical approach for space occupying mass in the pharapharyngeal space.

Piezoelectric-Assisted Removal of a Mandibular Cementoossifying Fibroma: An Innovative Technique

Diagnosis of cementoossifying fibroma is oriented by the clinical and radiological aspects of the lesion. Histology confirms the diagnosis. Treatment is surgical with enucleation-resection depending on the lesion size or wider resection with bone reconstruction in cases of large fibromas. The use of piezoelectric bone surgery is associated with low surgical trauma, exceptional precision, and fast healing response. It also allows easy performance of complex osteotomy and reduces the necessary dimensions of mucoperiosteal dissection. The purpose of the present article was to present the advantages of piezoelectric-assisted surgical removal of a cementoosseous fibroma of the mandible and to provide a precise description of the procedure using atraumatic surgery.

Piezosurgery for Treatment of Large Recurrent Mandibular Osteoma

BACKGROUND

Osteomas are infrequent benign bone tumors of uncertain etiology. They are usually situated at extremities and their occurrence in the jaws is relatively rare. There are 3 types of osteoma: central, peripheral, and extraskeletal. Preoperative presumptive diagnosis is performed by means of radiography using orthopantomographs, computerized tomographs, or cone beam scans. Treatment is surgical and consists of careful exeresis and curettage of the adjacent tissue. In recent years, piezoelectric surgery has been used to treat bone pathologies in the maxillofacial area, orthopedic surgery, and neurosurgery. When used for the exeresis of a bone lesion, the device minimizes risks and eliminates possible complications arising from affectation of the vascular and nerve structures close to the lesion.

OBJECTIVE

This clinical report describes a peripheral mandibular osteoma situated in the left mandibular basilar which recurred 45 years after surgical treatment at another center.

METHODS

For resection, the surgical approach followed the scar remaining from the earlier surgery and was performed using piezoelectric surgery. Surgery did not cause hemorrhagic complications, affect the sensitivity of the left labial menton, or cause paralysis of the lower lip.

CONCLUSIONS

Based on the present patient, it may be concluded that mandibular osteoma treatment by means of piezoelectric surgery makes precise exeresis possible with less affectation of the important surrounding structures such as the inferior alveolar nerve and the marginal mandibular branch of the facial nerve.

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.

Peripheral Osteoma of the Body of Mandible: A Case Report

Osteoma is a slow growing benign tumor consisting of well differentiated compact or cancellous bone that increases in size by continuous growth. It can be of a central, peripheral, or extraskeletal type. The peripheral type arises from the periosteum and is rarely seen in mandible. Although completely curable with adequate surgical treatment, osteomas precede the clinical radiographic evidence of colonic polyposis/Gardner's syndrome. Therefore they may be sensitive markers for the disease. Recurrence of peripheral osteoma after surgical excision is extremely rare. However it is appropriate to provide both clinical and radiographic follow up after surgical excision of peripheral osteoma. This article describes the case of a 45 year old male who presented with painless swelling of the right body of mandible and resultant cosmetic facial disfigurement and functional impairment.
