Between 1993 and 1996 we operated on 50 children with one of the follo
wing surgical indications: 17 children with a complication of acute rh
inosinusitis and the propagation of the process towards the orbit (per
iorbitis), six children with an ethmoid and sphenoid foreign body (shr
apnels shells), 11 children with an antrochoanal polyp, four children
with nasal polyposis in cystic fibrosis and 12 children with chronic r
hinosinusitis after 2-4 acute reinfections. The surgery was done under
endotracheal anesthesia with hypotension. CT axial and coronal tomogr
ams were done during the preoperative treatment. During the 2 weeks pr
eoperative treatment, the patients with polyposis and antrochoanal pol
yps were treated with 4-8 mg of cortisone per os or i.m., and also wit
h Fluticasone Propionate 100 mg twice a day and antibiotics in chronic
and acute rhinosinusitis. The children's age was between 7 and 15 yea
rs. In the patients with nasal polyposis and antrochoanal polyps (n =
15) post-operatively, we had four cases of synechiae, recurrent polypo
sis in two and antrochoanal polyps in two cases. (C) 1998 Elsevier Sci
