Salivary gland trauma is uncommon. Parotid gland and duct injuries are far more common than injuries to submandibular and sublingual glands due to anatomic position. Several methods of treating salivary duct injuries and their complications have been advocated. Optimal treatment outcomes can be achieved with early diagnosis, adequate evaluation, and proper management. This article presents current diagnostic and treatment protocols of salivary gland trauma. The anatomy of the salivary glands is briefly described and clinical cases are also presented to illustrate the treatment options described.
Primary malignant melanoma is only rarely found in the oral cavity (estimated at between 0.2 and 8 per cent of all melanomas) and occurs approximately four times more frequently in the oral mucosa of the upper jaw, usually on the palate or alveolar gingivae. A case is reported of a malignant melanoma in the mouth of a 74 year old male, which was originally diagnosed as reactive denture hyperplasia caused by a ill-fitting upper denture. Correction of the denture fault failed to stop the growth of the mass, which was therefore removed surgically. Histological examination revealed a melanin-producing tumour. A partial maxillectomy was performed and there was no evidence of recurrence over a three year follow-up period.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
