There are various surgical techniques designed to treat conchae bullosae (CB). These include partial or total resection and crushing. Frontal sinus balloon sinuplasty is thought to work by the crushing/remodeling of the agger nasi and frontal recess air cells. The long-term outcome of sinuplasty in the frontal/ethmoid air cell region is unknown. To date, no study has been done on the reformation of CB after crushing. We report on the long-term outcome of a series of patients who underwent crushing of their CB and suggest implications for frontal sinus balloon sinuplasty.
