Macroscopic evaluation of nasal mucosal regeneration after trauma (experimental study)

Abstract

Introduction. Adhesions as a manifestation of pathological regeneration in the nasal cavity after surgical interventions is a rather pressing problem of modern medicine.The aim of the study. was to evaluate the effectiveness of regenerative treatment regimens for nasal mucosal trauma under experimental conditions.Materials and methods. A randomized experimental study was carried out on 480 male white rats, divided into six treatment-dependent groups. At control times (2, 5, 10, 14, 21, 30, 42, 60 days), 10 animals were each removed from the experiment.Results. After nasal musocal trauma on the 2−5th day the processes of alteration prevailed, which were more pronounced in the group that did not receive anti-inflammatory treatment. In the group treated with a combination of the antioxidant “Demiphosphon” and the reparant “Derinat”, already from the 10th day there there was noted a restoration of the integrity of the mucous membrane of the wound edges, by the 60th day in all 10 (100 %) animals there was a complete closure of the defect. The incidence of adhesions in the group without treatment was 11.3 % with the use of reparative agents in the groups a statistically significant reduction of the adhesion process was observed.Discussion. Other authors have described the effects of various drugs on wound healing and adhesions. The effectiveness of hyaluronic acid remains controversial; in the study presented, no nasal adhesions were detected when sodium hyaluronate (“Olifrin”) was used.Conclusion. The best result was observed in the groups where the combination of the antioxidant “Demiphosphon” and the reparative agent “Derinat” was used: in addition to the absence of adhesions, earlier closure of the defect was noted. The inclusion of reparative agents in the treatment regimens increases the effectiveness of treatment by correcting the effects on reparative regeneration processes.
