[Morphological substantiation of surgical sanation of the ethmoidal labyrinth in patients with inflammatory pathology of frontal sinuses].

This study had the objective of evaluating intraoperative characteristics of sanation surgery for the correction of structural elements of ethmoid bone in 131 patients presenting with frontitis. Moreover, it included histological examination of the resected tissues. It was shown that chronic frontitis is associated not only with serious morphological changes in mucous membrane of the respective frontal sinusis and along the entire length of ethmoidal labyrinth but also with necrobiotic processes in the ethmoid bone plates, depending on the state of the ostiomeatal complex. It is supposed that these findings may account for irregular or low effect of conservative therapy of chronic frontitis and confirm the necessity of surgical sanation of ethmoidal labyrinth with due regard for the state of the ostiomeatal complex.
