Abstract
Sphenochoanal poyp is rare nasal mass that originates from sphenoid sinus. In anterior rhinoscopy it may be mistaken with antrochoanal polyp. CT of paranasal sinuses and nasal endoscopy has increased diagnostic accuracy. Simple polypectomy without removal of intra sinus mass is associated with increased risk of recurrence. Treatment of sphenochoanal polyp must include removal of intrasphenoid part via enlargement of the sphenoid sinus ostium. At present time the choice of the surgical approach for sphenochoanal polyp is endoscopic sinus surgery.
We introduce a case of sphenochoanal polyp and review its clinical, radiologic and pathologic findings and insist on endoscopic sinus surgery as a safe, effective treatment for it.

Abstract
Background: Sinus surgeries are usually associated with bleeding, thus can result in
hemodynamic instability. This study investigated the hemodynamic changes induced by remifentanil plus isoflurane administration in comparison with
propofol plus remifentanil in patients undergoing sinus surgery.
Methods: In this randomized clinical trial study, 96 patients were divided into two groups of isoflurane (1.2 MAC) plus remifentanil (44 patients, group A) and propofol (100 μg/kg/min) plus
remifentanil (52 patients, group B). Twenty-two patients in group A and 23 in group B were male. The remifentanil dosage (0.1 μg/kg/min) was equal
in both groups and all received 500 ml isotonic solution during the operation too. Premedications and anesthetic inductions of both groups were similar. The variables included age, BMI, blood loss during surgery, systolic and diastolic blood pressures, pulse rate and mean arterial blood pressure.
Results: The mean age, BMI, amount of blood loss, mean systolic (30 minutes before and after the intervention) and diastolic blood pressures (60 minutes before and after the intervention), pulse rate (30 and 60 minutes before and after the intervention), mean arterial blood pressure (60 minutes before and
after the intervention) were similar in both groups. The average mean arterial blood pressure, 30 minutes after the intervention (p=0.027) and the mean
diastolic blood pressure, 30 minutes after the intervention (p=0.011) in the case group had statistically significant differences with the controls.
Conclusion: Based on this study, the combination of isoflurane plus remifentanil could better maintain the hemodynamic stability during sinus surgeries.
