ABSTRACT
Neck infections can be broadly divided into superficial and deep infections (Figure 31.1). Superficial neck infections typically involve the skin and subcutaneous tissue, including the superficial fascia. These are further divided into non-necrotizing and necrotizing infections. Deep infections involve the deeper neck tissues, which are surrounded by multiple layers of fascia with potential spaces between them. It is important to have a clear idea of the deep cervical fascia and associated deep neck spaces to have a better understanding of deep neck infections and abscesses.
