Relevance: Modern endonasal surgery allows to remove polyps from all affected paranasal sinuses, following the principles of minimal invasiveness. Minimal traumatic of surgical intervention gives the best results, accompanied by less progression of the disease. Minimal invasiveness of surgical intervention and its obligatory combination with postoperative medical treatment are common practice in many countries. One of the drugs that actively effect the restoration of the mucous membrane of the nasal cavity and paranasal sinuses in the early postoperative period is Nazomer, which includes sodium hyaluronate and dexpanthenol in saline solution. The purpose of the study is to investigate the effectiveness of the drug Nazomer in patients with polyposis rhinosinusitis after endoscopic polyposynosotomy. Results and discussion: The main group consisted of 30 patients with polyposis rhinosinusitis, who were prescribed Nasomer in addition to standard treatment in the postoperative period. The control group included 30 patients who underwent standard treatment in the postoperative period. As criteria for clinical efficacy, data from endoscopic examination of the nasal cavity and indicators of anterior rhinomatometry, measured by the «Optimus» device, were selected. In the main group, the index of nasal breathing according to rhinomatometry was better than the results of patients in the control group on the 3rd and 5th day of the postoperative period by 26% and 24%, respectively. Conclusion: The use of the drug Nazomer in the postoperative period in patients with polyposis rhinosinusitis contributes to more active restoration of respiratory function of the nasal cavity compared with the control group, according to rhinomatometry, up to 26%. Based on the results obtained, the drug Nazomer is an effective anti-inflammatory and regenerative agent in the postoperative period in patients with polyposis rhinosinusitis.

AbstractObjectives:This study assessed the utility of current sialendoscopes in the paranasal sinuses in a cadaveric model and evaluated novel uses for sialendoscopes.Methods:Currently available sialendoscopes were used for visualisation and performing interventions in the paranasal sinuses. Ten cadaver heads were studied before and after dissection. Outcomes included ostia identification, sinus cannulation, success of mucosal biopsy collection and image clarity.Results:Marchal and Erlangen sialendoscopes were found to be effective for both visualising and cannulating the sphenoid sinuses before and after dissection. Both types demonstrated poor maxillary ostia visualisation without dissection, but did allow treatment after antrostomy. Larger diameter sialendoscopes were associated with the lowest image distortion during maxillary ostia assessment. Mucosal biopsy collection within the sphenoid sinus, but not in the maxillary sinus, was possible before dissection.Conclusion:Sialendoscopes can be used for visualisation and performing interventions in the sinonasal cavity, but their utility is mainly limited to the sphenoid sinus. They may be considered a minimally invasive method for drug delivery and/or biopsy collection in the post-operative setting for all sinuses. Design improvements are suggested.
