[The course of repair processes in the maxillary sinuses after radical surgery]

87 patients with chronic purulent hyperplastic and cystic maxillary ethmoiditis have undergone a radical surgical treatment with Caldwell-Luc operation as a surgical approach. Histopathological parameters of maxillary mucosa before and after surgery were compared. Mucociliary clearance, formation of postoperative anastomosis, changes in sinus microflora were followed up. Causes of recurrent postoperative chronic processes in the paranasal sinuses were analysed.
