Methods The study was performed on 20 New Zealand white rabbits, distributed into two equal groups. In the case of the first group of 10 experimental animals, we induced the model of ipsilateral double obstruction, the opposite side being left intact as term of comparison. Thus we produced the mechanical obstruction of the nasopharynx at the level of the choanal orifices as well as the obstruction at the level of ostiomeatal complex. In the case of the second experimental group we induced the model of the double counterlateral obstruction: the obstruction of the nasopharynx at the level of the choanal orifice and the counterlateral obstruction of the ostiomeatal complex. We studied and determined the qualitative changes of the pH and the microbiology of the paranasal sinus mucosa.
