Introduction. Chronic rhinosinusitis, a very common inflammatory condition, is a main public health issue affecting the quality of life. Furthermore, some patients do not respond to either medical or surgical intervention, which could be explained by the presence of the bacterial biofilm in the rhinosinusal zone. Objectives. The aim of this study is to evaluate the influence of endoscopic sinus surgery on olfactory impairment caused by chronic sinusitis with and without nasal polyps (CRSNP and CRS), by testing the olfactory function and potential dysfunction before and after endoscopic sinus surgery. Another objective is to find a connection between the percentage of coverage with bacterial biofilm of the nasal mucosa from patients with CRSNP and CRS and to evidence the fountain of infection role of the bacterial biofilm, while demonstrating that antibiotic therapy is not efficient once the bacterial biofilm is formed in the nasal sinuses. Materials and methods. We investigated 123 patients with CRSNP and CRS, which underwent functional endoscopic sinus surgery (FESS). The olfactory function was tested pre and post FESS. We also analyzed and compared the scores of endoscopic images of Lund-Kennedy and CT staging scale of LundMackey for the two study groups. The degree of olfactory rehabilitation in patients with CRSNP and CRS was evaluated performing smell diskettes test. The presence of bacterial biofilm on the surface of the nasal mucosa extracted during FESS from patients with CRSNP and CRS was examined with the electronic microscope and the percentage of coverage with bacterial biofilm was measured with Carnoy software. Results. Bacterial biofilm was present in a higher percentage in patients with CRS vs. CRSNP. By comparing the level of olfactory function, significant improvement was found after FESS intervention in both study groups. Postoperatively, Lund-Kennedy scores decrease significantly for the whole group (Z = -9.66 at p < 0.001, d Cohen = 4.40), indicating the major role of surgery in the treatment of CRS. The decrease in Lund-Kennedy score values is also significant for each group. In the case of subjects diagnosed with CRS, the mean values decrease from 6.57 (preoperative) to 0.90 (postoperative), respectively Z = -6.779 to p < 0.001. In the case of subjects diagnosed with CRSNP, the mean values decrease from 9.03 (preoperative) to 1.44 (postoperative), Z = -6.927 at p < 0.001. Out of the total number of patients included in the study, 59 patients tested positive with the Prick test for dust and mites and more than half of the patients with positive allergy test were from the lot diagnosed with CRSNP. Conclusions. FESS plays an important role in the improvement of olfactory function in patients with CRS. Bacterial biofilm was present in both study groups but in higher percentage in the CRS group and was found in lower percentage in the group with positive allergy tests. The CRSNP group presented a higher positive result regarding the allergy Prick test and a lower percentage of coverage with bacterial biofilm of the nasal mucosa. In conclusion, chronic rhinosinusitis with or without nasal polyps that is refractary to antibiotic therapy should be directed to the ENT department in order to receive surgical therapy in order to improve olfactory function.
Chronic rhinosinusitis with chronic adenoiditis in children represents a global public health issue, seriously affecting the quality of parents and children life, because of its irritating symptoms like intermittent snoring, mouth breathing, dry mouth, nasal obstruction, headaches increased irritability and focus disorders on children. Bacterial biofilms are highly associated with the chronic infectious processes in children. Correct therapeutical management of this diagnostic combination is mandatory to improve the quality of one’s life. Objectives. The aim of the study is: to observe the ratio of adenoid mucosa covered with bacterial biofilm extracted from the nasopharynx of 50 paediatric patients suffering of chronic rhinosinusitis (RSC) and chronic adenoiditis (CA); and to point the fact that the adenoids contaminated with bacterial biofilm are a generator for chronic upper airway infections in children. Material and methods. We have measured using an image analysis program the bacterial biofilm covering the entire surface of the extracted adenoids mases, from 28 girls and 22 boys aged between 5 and 12 years diagnosed with CRS and CA. Control visits were performed to verify symptom improvement at 1, 3 and 6 months. Outcomes. Adenoids extracted from paediatric patients diagnosed with CRS and CA presented bacterial biofilms coverage on almost the entire mucosa (86.75%). Conclusions. Adenoid mases removed from paediatric patients with CSR and CA have most of their mucosal covered with bacterial biofilm. In the nasopharynx of paediatric patients with CSR and CA, bacterial biofilm can play the role of a constant fountain of infection. Adenoid mass removal explains the symptomatic improvement observed post operatory in the CRS with CA paediatric patients that do not respond to antibiotic therapy.
