[Treatment of deep neck infections]

The incidence of deep neck space infections has been significantly reduced by modern antibiotic therapy. These infections are relatively rare and yet the life-threatening complications merit special consideration by head and neck surgeons.

Seven cases of deep neck space infections as a consequence of purulent pharyngitis (3), peritonsillar abscess (2), retropharyngeal (1), and odontogenic (1) abscess are presented. Despite antibiotic therapy according to antibiogram all patients showed an increase in complaints with persisting febrile temperatures and rising inflammation parameters. Surgical intervention became necessary. In two cases the infection spread into the mediastinum.

All patients were completely cured by means of early surgical intervention including extensive drainage of the primary focus, deep neck spaces and mediastinum, accompanied by intravenous antibiotic therapy. Tracheotomy was performed on one patient with increasing dyspnea. All patients had an uneventful recovery without major postoperative complications.

The clinical course of the disease must be observed particularly closely even after starting antibiotic therapy and identification of the infectious focus. Antibiotic therapy may in some cases cover clinical symptoms. However, in the presence of abscess formation or necrotizing infections, antibiotics can prove to be ineffective. The optimum time for surgery is difficult to determine. Complete drainage of the neck spaces down to the mediastinum is a safe procedure to save the patients' life. This shortens the duration of the disease and prevents complications. The most common problems in the management of deep neck space infections are discussed.
