Abstract
Controversy exists regarding the management of the middle meatus after pediatric functional endoscopic sinus surgery (FESS). To prevent adhesions following pediatric FESS, gelatin film stenting of the middle meatus has been recommended. The effects of stenting, however, have not been established. Fifty-one children with similar degrees of bilateral sinus disease had a gelatin film stent placed in one middle meatus on completion of FESS, while the opposite meatus was not stented. Two to three weeks later at the time of a second, staged procedure, the sides were compared for the presence of the stent, adhesions, granulation tissue, and patency of the maxillary sinus ostia. In 11 children the postoperative findings were more severe in the side without the stent, whereas in 29 children they were more severe in the stented side. There was no difference between the sides in 11 children. Although gelatin film stenting benefits some children, it should not be used routinely following pediatric FESS but should be reserved for children who are predisposed to develop adhesions or have poor prognostic factors, such as immunodeficiency and ciliary dyskinesia.
