Pediatric Guidelines: Head and Neck Infections - Orbital Cellulitis

PrintPrintPDFPDF

Need for drainage/source control of head and neck infections should be evaluated carefully in consultation with Pediatric Otolaryngology, Head and Neck Surgery, and Ophthalmology when the orbit is involved. If initial non-operative management is chosen, a narrow spectrum regimen (i.e. without vancomycin) is encouraged to faciliate transition to oral therapy. 

ID consultation is recommended for head and neck infections occurring in immunocompromised patients, and for those with atypical features, chronic course, or lack of response to first line therapy.
