Solitary Peripheral Osteoma of the Angle of the Mandible

[Endoscopic endonasal surgery of paranasal sinus osteomas]

This article was designed to summarize the experience gained withendoscopic endonasal removal of paranasal sinus osteomas during the period from January 2013 till February 2016. In addition a review of the relevant literature is presented encompassing the publicationsthat provide information about etiology, pathogenesis, clinical picture, diagnostics, and treatment of bone tumours. The objective of the study was to enhance the effectiveness and safety of the surgical treatment of the patients presenting with paranasal sinus osteomas. A total of 81 cases of paranasal sinus osteoma were documented in the patients admitted to I.P. Pavlov Saint-Peterburg First State Medical Universityduring the period from January 2013 till February 2016. Forty nine of them were given the surgical endoscopic endonasal treatment with the removal of the neoplasm. The remaining 32 patients were included in the group for the further dynamic follow up. The authors report the data of morphological studies and the results of computed tomography performed in the pre- and postoperative periods with special reference to the potential for the use of the electromagnetic navigation station (an image-guidance system) that makes it possible to significantly reduce the risk of development of possible complications. In addition, the findings suggestive of the progressive tumour growth in the group of the patients under dynamic observation are discussed.

Cancellous osteoma of maxilla: A rare case report

Osteoma is a slow growing benign tumor result from either cancellous or compact bone proliferation. Osteoma of the jaws may arise from the surface of the bone as a sessile mass located either peripherally or endosteally. This paper presents a rare case report of peripheral cancellous osteoma, involving the buccal cortical plate and alveolar process of the right maxilla of a 37-year-old female patient.

Oral and maxillofacial considerations in Gardner's syndrome: a report of two cases

Gardner's syndrome (GS) is a genetic disorder characterised by intestinal polyps, multiple osteomas, and soft-tissue tumours. Dentists play an important role in the syndrome diagnosis considering that craniomaxillofacial osteomas are a major criteria for Gardner's syndrome diagnosis. This study aimed to describe the main stomatological manifestation of GS and the importance of dentists in its diagnosis. Two patients presenting GS were evaluated. The first one had two osteomas in the mandible and GS was suspected. The colonoscopy confirmed the presence of polyposis and a prophylactic proctocolectomy was performed. The other patient had a late-stage diagnosis of GS and developed a rectum adenocarcinoma. The presence of craniomaxillofacial osteomas are a hallmark of the disease. Early-stage GS diagnosis may enable early diagnosis and preventive strategies in carriers. Other dental abnormalities, such as supernumerary teeth, hypercementosis and odontomas, can also be observed.
