ABSTRACT
This chapter discusses the neck infections under the headings of superficial and deep infections. The superficial neck infections typically involve the skin and subcutaneous tissue, including the superficial fascia. These are further divided into non-necrotising and necrotising infections. Impetigo is a common superficial bacterial skin infection primarily caused by Staphylococcus aureus and is most frequently encountered in children. The lesions are mostly located in the head and neck region. Erysipelas and cellulitis are the most common skin and soft tissue infections requiring in-hospital treatment. Throat infections include: Acute pharyngitis, Tonsillitis, Peritonsillar cellulitis, Peritonsillar abscess, Glandular fever, Epiglottitis and Supraglottitis. With advancements in laboratory testing, radiological investigations and broad spectrum antibiotics, the overall morbidity and mortality of deep neck infections (DNIs) have improved. Some patients with DNIs can present in a moribund condition with impending airway compromise, and securing the airway must take priority for such patients.
