RESUMO
There are very few indications for surgical management of chronic rhinosinusitis in children. This has been partly due to the fact that the definition of what qualifies as racalcitrant sinusitis in children is still obscure. There is also significant evidence in literature that surgery, especially radical surgery, on the nose and sinuses in children would result in some interference with the growth of the facio-maxillary skeleton. The advent of Functional Endoscopie sino-nasal Surgery ( F. E. S. S. ) in recent years has changed the philosophy of surgery for paediatric rhinosinusitis and has proven to be an effective choice of management in difficult cases. We persent here our experience and preliminary results with the use of FESS in nine children with sinonasal disorders including cystic fibrosis. The usefulness of the recently described Lund- mackay and Kennedy Scoring System for chronic rhinosinusitis in terms of symptom score, radiological score, endoscopie score and surgical score has been demonstrated.
