Metastatic involvement of the maxillary antrum from an uncommon source.

UNLABELLED: Metastatic involvement of the jawbones is uncommon, particularly in the maxilla. Case reports of such metastases from renal cell primaries are few, making a consensus on treatment difficult to establish. We present a case of metastatic involvement of the maxilla two years following a nephrectomy for renal cell carcinoma. The case exemplifies the broad range of symptoms attributable to metastases in the maxilla and the management dilemmas. CLINICAL RELEVANCE: The case highlights the role of practitioners in primary dental care in identifying the potential for such pathology based on clinical and radiographic features.

The role of alcohol in maxillofacial trauma: a comparative retrospective audit between the two centers.

Alcohol abuse and maxillofacial trauma, particularly that due to interpersonal violence, have a well-established relationship in the literature. We present a retrospective audit comparing the role of alcohol in maxillofacial trauma between Selly Oak Hospital in Birmingham, United Kingdom and Westmead Hospital in Sydney, Australia, and the association between alcohol involvement and patient demographics, including age, sex, marital status, and employment status. Also presented are the differences between the two centers in terms of mechanisms and types of injuries and the locations where these injuries were sustained. Alcohol was involved in 34.78 and 30.77% of patients at Westmead and Birmingham, respectively. A multiple logistic regression analysis revealed a reduced likelihood of alcohol involvement in episodes of maxillofacial trauma where patients were unemployed (P=.04), and where injuries were sustained secondary to mechanisms other than assault (P<.001) and in locations other than pubs and nightclubs (P=.024). There appeared to be no statistically significant contribution to the likelihood of alcohol involvement by treating center, marital status, patient sex, or age. Alcohol continues to be a strong driving factor in cases of maxillofacial trauma, particularly those due to alleged assault, with a typical patient demographic of the gainfully employed frequenting drinking establishments being most at risk for alcohol-related trauma, most commonly sustaining their injuries secondary to assault. Identifying patient groups most at risk is a key step in developing public health strategies aimed at prevention, and our findings would appear to suggest this group of patients as being the most worthwhile to target with measures aimed at reducing alcohol-fueled maxillofacial trauma.
