The purpose of the study was to compare three types of general anesthesia for functional endoscopic sinus surgery (ESS) with controlled hypotension measuring the quality of visibility of the surgical field and the blood loss during the operation. Seventy-one patients underwent endoscopic ethmoidectomy bilaterally for nasal polyposis and/or chronic sinusitis. The patients were divided into three groups according to the type of anesthesia they had: group A (sufentanil/sevoflurane), group B (remifentanil/propofol), and group C (fentanyl/isoflurane). The mean estimated blood loss for group A was 117.83 ml, for group B it was 100.5 ml and for group C it was 198.89 ml. The average quality of visibility of the surgical field was 1.57 for group A, 1.3 for group B and 2.79 for group C. The quantity of blood loss (p < 0.01) and the visibility of the surgical field (p < 0.001) demonstrated a difference among the three groups. Remifentanil and sufentanil during functional ESS enable controlled hypotension and a general improvement in surgical conditions.
