1. The document discusses various types of tissue space infections, including Ludwig's angina, which is a potentially life-threatening bilateral infection of the submental, sublingual, and submandibular spaces. 2. It describes the surgical anatomy and contents of different tissue spaces like the submandibular, sublingual, pterygomandibular, and submental spaces. 3. Causes, clinical features, treatment and importance of properly draining abscesses are covered for different tissue space infections.

2. Tissue space infection

Space is misnomer so it is clefts
(apotential space between the fascial
layers which contain CT AND Various
anatomical structures ) there is no voids in
the tissue.
