[Pathologies of lateral nasal wall in children with diagnosed antrochoanal polyps]

Antrochoanal polyps are more frequent in children than in adults. Patomechanism of their development is still unclear. New diagnostic methods allow precise examination of lateral nasal wall pathologies.

Aim of the study is an evaluation of endoscopic examinations and CT scans of lateral walls in 15 children with chronic sinusitis and diagnosed antrochanal polyps.

Both groups of children, those with chronic sinusitis and those with diagnosed antrochoanal polyps, were compared according to the results of the endocopies and CT scans.

Unilateral pathologies of lateral nasal wall, like notable widening of natural ostium in 4 children and additional ostium in 7 children with antrochoanal polyps were noted. In children with chronic sinusitis pathologies were observed bilaterally, in none of them additional ostia were observed and pathologies of lateral nasal wall were typical for chronic inflammatory process or trauma.

Diagnosed pathologies of lateral nasal wall in both children are different and need further studies, which may lead to explanation of antrochoanal polyps development.
