The most frequent swellings in the maxillofacial region can be traced to odontogenic inflammations. Chronic dental foci exacerbate and break through the soft tissue layer surrounding the jaw. There the purulent material quickly spreads along the muscular pocket and simulates a phlegomonous inflammation. Inflammations of the individual soft part niches have characteristic symptoms. Because of the loose interconnections the infectious material can spread very quickly into the parapharyngeal space and from there downwards into the mediastinum or upwards into the base of the skull. Because of the danger of an advance in these spaces, it will be necessary to incise the swellings on time.
