Contemporary management of deep infections of the neck.
Odontogenic infections rarely lead to involvement of the lateral and retropharyngeal spaces. When this does occur, the microbiology of the infection is similar to the typical odontogenic infection, ie, Streptococcus and oral anaerobes including Peptostreptococcus, Bacteroides, and Fusobacterium. There is an increased incidence of Fusobacterium seen in the more severe infections, as well as a higher incidence of Streptococcus milleri. Many patients who have deep cervical infections also have some compromise in their host defense mechanism, such as diabetes. The signs and symptoms of deep cervical space infections are similar to those of the severe submandibular space infection, but also includes sialorrhea, respiratory distress, odynophagia, and dysphagia. Lateral soft-tissue radiographs of the neck are useful in assisting with the diagnosis of retropharyngeal infections, and CT scans can provide definitive information regarding lateral pharyngeal space involvement. Treatment includes the use of high-dose intravenous bacteriocidal antibiotics. The recommended antibiotics are penicillin-metronidazole, ampicillin-sulbactam, or clindamycin. Certain cephalosporins may also be useful in selected patients. Early surgical intervention is also indicated. Aggressive incision and drainage of all of the involved spaces is necessary to assure early resolution of the infection. Continual airway monitoring and the establishment of surgical airways is the final portion of the treatment triad.
