4 Clinical Trials for Various Conditions
The purpose of the research is to examine the effectiveness of navigation in maxillary sinus balloon dilation for the treatment of chronic maxillary rhinosinusitis.
A prospective, single-arm, post approval pilot study.
Mucosal biopsies, endoscopically-guided brush samples of mucus, and a saline lavage taken from the maxillary sinuses of ten CRS patients undergoing sinus surgery are analyzed using three microarrays in order to detect bacteria, fungi and viruses. Ten control patients with normal sinuses will have the same samples taken. The hypothesis is that bacterial, fungal, and viral communities present in the maxillary sinus of patients with CRS are significantly different from those patients with healthy sinuses, and that microorganisms identified in patients with or without CRS will differ from previously published data obtained using other techniques.
This study is designed to evaluate safety and effectiveness of a less invasive procedure to treat maxillary only, or maxillary and anterior ethmoid, chronic sinusitis. Additionally, this study will assess the feasibility of performing the procedure under local anesthesia.
