Morphological and functional state of the nasal cavity after surgical interventions in the vertical section of the lacrimal ducts

Objectives - to compare the condition of the nasal cavity after a dacryocystorhinostomy of external and endonasal access. Material and methods. Comparative assessment of the results of the study of 96 patients with chronic dacryocystitis was done. The patients were divided into 2 groups: group 1 included persons who underwent the videoendoscopic endonasal dacryocystorhinostomy; group 2 - patients with external dacryocystorhinostomy. For all the participants, there were registered the complaints and anamnesis, the data of video-endoscopy of the nasal cavity, anterior active rhinomanometry, transport and olfactory functions. The information on the state of the nasal cavity after surgery in the vertical section of the lacrimal ducts was also obtained. Results. In both groups we revealed the changes in the mucous membrane, in the anatomical structures of the nasal cavity, in the mobility of the ciliated epithelium, respiratory functions and olfaction. When comparing the results in both groups, the statistically significant differences were found in the questionnaire data - a complaint of lacrimation, and the data on the mucociliary clearance disorders (p<0.05). Conclusion. According to the questionnaire data, in group 2, after external dacryocystorhinostomy, lacrimation was more often observed -in 63.63% of patients. An increase in the time of mucus advancement up to 35.0 minutes (normal to 15.0 minutes) in group 2 is most likely due to the more common thickening of the lower nasal concha, if compared to patients in group 1.
