Rhinosinusitis is one of the most commom causes of fever of unknown origin in critically ill patients and should be systematically searched. OBJECTIVE: This study aims to evaluate the diagnostic and therapeutic effect of maxillary sinus puncture performed at the bedside in patients with infective rhinosinusitis hospitalized in an Intensive Care Unit of a high complexity care hospital. MATERIALS AND METHODS: This retrospective study looks into patients on mechanical ventilation with fever of unknown origin and signs of rhinosinusitis on CT images who were submitted to inferior meatus maxillary sinus puncture. RESULTS: The total study sample consisted of 27 patients (70.3% male; mean age 45.3 years). The most common Intensive Care Unit admission diagnoses were head trauma and stroke. CT scans revealed the maxillary (85.2%) and sphenoid (74.1%) sinuses were the most involved paranasal sinuses. Middle meatus purulent drainage was seen in 30.7% of the nasal cavities. Fever was reduced in 70.4% of the patients after puncture (p < 0.001). The most commonly found organisms in sinus aspirates were Pseudomonas aeruginosa and Acinetobacter baumannii. CONCLUSION: Maxillary sinus puncture performed at the bedside of the patients is an important diagnostic and theraupetic tool for critically ill patients.
