Nasal saline irrigation is the corner stone of postoperative care after functional endoscopic sinus surgery (FESS) for chronic rhinosinusitis (CRS). However, intrasinus penetration of the saline solution can be challenging and may require difficult head position, particularly for the frontal sinus. Our aim was to evaluate a novel device for direct intrasinus self-irrigation, usable at home for both maxillary and frontal sinus.Thirty devices were implemented in 23 patients: in the maxillary sinus for 18 patients and in the frontal sinus for 5 patients. The device was removed after 7 days on average (5-10 days), and nasal saline irrigation was carried on with a squeeze bottle for 6 weeks. Retrospective evaluation of the device included: device-related complication, patient satisfaction, and ostial or middle turbinate synechiae at 3 months.No device-related complication (obstruction, displacement, infection, bleeding) occurred. Twenty-one (91.3%) patients were satisfied with the device. Two patients required the help of a nurse for irrigation. No ostial of middle turbinate synechiae was visualized at 3 months. This new endonasal device enables direct intrasinus self-irrigation after FESS for CRS.This preliminary study showed that this device is safe and easy to use. However, further investigations are required to assess its potential role to reduce the risk of synechiae and revision surgery.
