1 | Introduction
Many potential fascial spaces with loose tissue structure are continuous
with each other in maxillofacial and neck, which lead to infection easy
to spread(1). Deep neck space infections
(DNSI) refer to the infections of
deep neck space and fascia plane, which can induce cellulitis and even
the formation of abscess. It is a common emergency in department of
otorhinolaryngology and head and neck surgery. If not given effective
treatment in time, it is easy to cause multi-space fusion infection
because of its rapid development. It can induce severe complications
such as dyspnea, carotid sheath infection, laryngeal edema,
mediastinitis, mediastinal abscess and intracranial infection(2,3). How
to distinguish the severity of abscess, the indications and timing of
surgery, how to ensure airway patency, nutritional support and
post-treatment after sepsis incision and drainage have become the main
factors to successfully treat DNSI.
