Guidewire insertion in this study was noted to frequently create a false passage during maxillary sinus ostial dilation. After balloon dilation, irrigant penetration was increased into the sphenoid sinus for heavy and mist irrigators whereas the maxillary sinus had diminished irrigant penetration for heavy and NetiPot irrigators.

This procedure uses a technique familiar to otolaryngologists and may be used for pituitary and other skull base tumors.

The addition of surfactant to saline irrigation improves ostial penetration in undissected and undiseased cadavers. This has practical implications for unoperated patients seeking care for sinus-related symptoms in that we have now described a method for improving topical treatment of target sinus mucosa prior to surgical intervention.
