ABSTRACT
OBJECTIVE:
The extent of surgery, the type of device used and head position may influence nasal irrigation. The aim of this study was to determine the effectiveness of topical irrigant delivery to the paranasal sinuses according to these factors.METHOD:
Four cadaveric heads underwent four stepwise endoscopic dissections. Irrigations were evaluated after every stage using different delivery devices (squeeze-bottle, gravity-dependent device and syringe) in two head positions (nose-to-sink and vertex down). Irrigant penetration into each sinus was estimated using a four-point scale.RESULTS:
A significant positive effect of surgery was demonstrated for each sinus as well as for the delivery device. High-volume irrigant devices are more effective, and the head position plays a significant role in irrigant distribution to the frontal sinus.CONCLUSION:
This study further confirms the efficacy of high-volume irrigant devices. A vertex down position during the irrigation could improve delivery to the frontal sinus, and the widening of the ostia increases irrigant access to the sinuses.Mots clés
