Role of Oral Microbial Infections in Oral Cancer.

The role of bacterial and viral carcinogenesis in the oral cavity is increasingly of interest, as a means to provide more methods of cancer prevention. There may be relationships between bacteria and multiple strains of viruses in the progression of malignancy. Cancer cause is closely related to the type of carcinogen, as well as the synergistic or additive actions of combined risk factors, the susceptibility of the host, and duration of interaction between host and exposure to risk factor.

Eagle Syndrome Presenting after Blunt Trauma.

As classically described, Eagle syndrome is an entity where patients develop pain or neurologic manifestations arising from an elongated styloid process and/or an ossified stylohyoid ligament irritating or compressing adjacent cranial nerves or the carotid arteries. Over the past few years, there have been reports of actual injury to the internal carotid artery with dissection, occlusion, and strokes. We present 3 cases identified after blunt trauma: 1 due to carotid compression and 2 due to actual injury to the internal carotid artery.
