Medical Care
The primary goals of management of acute sinusitis are to eradicate the infection, decrease the severity and duration of symptoms, and prevent complications. Most patients with acute sinusitis are treated in the primary care setting. Further evaluation by an otolaryngologist is recommended when (1) continued deterioration occurs with appropriate antibiotic therapy, (2) episodes of sinusitis recur, (3) symptoms persist after 2 courses of antibiotic therapy, or (4) comorbid immunodeficiency, nosocomial infection, or complications of sinusitis are present. The goals of management of acute sinusitis are the provision of adequate drainage and appropriate systemic treatment of the likely bacterial pathogens.
Drainage of the involved sinus can be achieved both medically and surgically (see the Medication and Surgical Care sections). Aggressively treat patients in intensive care who develop acute sinusitis in order to avoid septic complications. Consider removal of nasotracheal and nasogastric tubes and promote drainage either medically or surgically.
Surgical Care
Sinus puncture and irrigation techniques allow for a surgical means of removal of thick purulent sinus secretions. The purpose of surgical drainage is to enhance mucociliary flow and provide material for culture and sensitivity. A surgical means of sinus drainage should be used when appropriate medical therapy has failed to control the infection and prolonged or slowly resolving symptoms result or when complications of sinusitis occur. Another indication for sinus puncture is to obtain culture material to guide antibiotic selection if empiric therapy has failed or antibiotic choice is limited. This is particularly important in patients who are immunocompromised or in intensive care. Sinusitis can be a prominent source of sepsis in these patients. In adults, sinus puncture can usually be achieved using local anesthesia; however, in children, a general anesthetic is usually necessary.
In today's era of minimally invasive surgical techniques, sinus endoscopy is commonly used to achieve sinus drainage. It offers the advantages of (1) being able to open multiple sinuses or to decompress the orbit in cases of complications and (2) allowing the surgeon to open the natural ostia of the involved sinuses.
The techniques and complications of open and endoscopic sinus surgical approaches are discussed in articles dealing with their individual surgical management.
Consultations
Ophthalmological or neurosurgical consultation should be obtained when either orbital or intracranial complications develop.
