Abstract
According to our experimental study, it is obvious that an antibiotic solution is very effective in the treatment of sinusitis if it can be introduced in the paranasal sinuses constantly by a nebulizer. In this study using a jet nebulizer and RI (99mTc) counting technique for assessment, it was confirmed that the effort to make the middle meatus open by ENT specialists is quite important. In sinusitis cases with nasal polyps, polyps should be removed surgically in advance. In complicated sinusitis cases with nasal allergy, hyperthermia was effective as a preparatory step before jet nebulizer therapy. Catecholamines spray and/or gauze applied in the middle meatus can be a possible treatment for effective nebulizer therapy. After these treatments, swallowing duringnebulization increased the total count of RI introduced in the maxillary sinuses. While nebulizer therapy is quite easy in the out patient clinic, its indication to, and pretreatment of the middle meatus must be accurately assessed in each case for effective treatment of sinusitis.
