Balloon dilation is noninferior to FESS for symptom improvement and superior to FESS for postoperative debridements in patients with maxillary and anterior ethmoid disease. Balloon dilation is an effective treatment in patients with uncomplicated CRS who meet the criteria for medically necessary FESS.

With 1-year follow-up, standalone balloon dilation is as effective as FESS in the treatment of CRS in patients with maxillary sinus disease with or without anterior ethmoid disease who failed medical therapy and met the criteria for medically necessary FESS.

Stand-alone balloon dilation of the maxillary sinus ostia and ethmoid infundibula performed in the office is well tolerated and effectively treats both CRS and RARS.

These results indicate that sinus-related health problems impose a substantial burden on work productivity and physical/mental activity levels. Treatment of CRS by dilating the maxillary sinus ostium and ethmoid infundibulum can significantly improve quality of life (QOL) and work productivity.

These results indicate that transantral balloon dilation of the ostiomeatal complex under local anesthesia appears to be a safe technique for managing isolated maxillary or maxillary and anterior ethmoid sinusitis and can potentially be performed safely in an office setting.
