space under the chin (submental space) located in the suprahyoid region, the submental triangle within a single space. A small amount of adipose tissue within the gap and lymph nodes, this gap for the mylohyoid muscle, the submental hyoidmuscle and the sublingual space apart. Connected with the submandibular space on both sides, the infection spread easily with each other (Figure 1).
submental space infections come from the lymph node inflammation. Lower lip, tongue, floor of mouth, sublingual caruncle, mandibular anterior teeth and periodontal tissues of the lymphaticflow can be remitted directly to the submental lymph nodes, it is more than one region of inflammation, mouth ulcers, mouth under the chin can cause go far lymphadenitis and cellulitissecondary to the submental space.
submental space as much as the lymph nodes caused by infection, it is generally slow progression, early limited lymph node enlargement, obvious clinical symptoms. When extranodal spread to the lymph node inflammation, the gap was caused by cellulitistissue inflammation, swelling extended to cover different time to the submental triangledevelopment area, skin redness, pain. abscess formation after local skin purple, palpable pressure fluctuations have pitting edema, and infection. Back when the infection spread to submandibular space, and can demonstrate the appropriate symptoms.
lower lip, tongue, floor of mouth, sublingual caruncle, mandibular anterior teeth and periodontal tissuelymphatic drainage can be remitted directly to the submental lymph nodes, so the need to actively treat more than one region of inflammation, oral ulcers, mouth go far, avoid submental lymphadenitis, cellulitis and secondary to the submental space.
