Two huge maxillofacial osteoma cases evaluated by computed tomography

Giant Osteoma of the Mandible: Report of a Rare Case with Review of Literature

Osteoma is a slow growing, asymptomatic, benign bony tumor composed of compact and cancellous bones. Central, peripheral, and extra skeletal osteomas are the three types based on the site of origin. They are mostly observed on routine radiographic screening, mostly in the paranasal sinuses. Gnathic involvement is an uncommon occurrence, and if present, mandibular involvement is more frequently seen. Mostly, osteomas are small asymptomatic lesions and very rarely they become symptomatic and acquire larger size. Multiple osteomas are a feature of Gardner's syndrome; however, solitary osteomas are non-syndromic. Oral health professional may be the first to diagnose Gardner's syndrome as the osteomas may be initial manifestation of the disorder. Treatment protocol of osteomas varies based on the associated signs and symptoms. Small, asymptomatic cases are treated conservatively by periodic clinical and radiographic evaluation. However, larger, symptomatic lesions require surgical intervention. Herby, reporting an unusual case of Giant peripheral osteoma of the mandible. Our case is unique in few aspects because of its unusually large size (5 × 4 cm) and involvement of lingual aspect of the mandible in the region of sublingual fossa, with compression of the floor of mouth.

Giant fronto-ethmoidal osteoma - selection of an optimal surgical procedure

Introduction

Osteomas of the paranasal sinuses are benign bone tumours that produce clinical signs depending on their size and location. In most reported cases large tumours are excised by an external approach or in conjunction with an endoscopic technique. Endoscopic treatment of such tumours is a huge challenge for the operator.

Objective

Determine the optimal surgical approach by analysing giant osteomas of the frontal and ethmoidal sinuses in the literature.

Methods

Group of 37 osteomas obtained from the literature review. A group of osteomas removed only by endoscopy was compared with a group in which an external approach (lateral rhynotomy or craniotomy) or combined external and endoscopic approach was applied.

Results

The authors, based on the statistical analysis of the literature data, have found that the average size of osteomas excised endoscopically and those removed by external approaches does not differ statistically, when the osteomas are located in the ethmoidal cells (p = 0.2691) and the frontal sinuses (p = 0.5891).

Conclusion

The choice of surgical method appears to be independent of the osteoma size and the decision is likely to be taken based on the experience of the surgeon, available equipment and knowledge of different surgical techniques.

Peripheral osteoma of the hard palate: a rare case report and literature review

Osteomas are benign osteogenic tumors that are composed of cancellous or compact bone. They are usually sessile tumours composed of dense sclerotic, well-formed bone projecting out from the cortical surface. They commonly occur in skull and facial bones, however, excluding the maxillary sinuses, the maxilla is a rare site for osteomas. Therefore, we aim to present a case of maxillary osteoma in a 19-year-old male patient and to provide an overview of current literature on the diagnostic options and treatment modalities. To best of our knowledge, in the English literature, this is the seventh reported case of maxillary osteoma which is located on the hard palate.

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.
