Septoplasty is one of the three most frequently performed operations in otorhinolaryngology. The history of the development has more than 200 years. The research and analysis of the features of different methods of this surgical treatment does not lose interest to this day. The article presents an analysis of the restoration of the functions of the nasal cavity after septoplasty. The research included 96 patients with various types of nasal septum deformities. The age range of patients ranged from 19 to 54 years. All patients had nasal septum correction under general anesthesia. Patients were divided into 2 groups. The 1st group included 64 patients who had endoscopic septoplasty. The 2nd control group consisted of 43 patients with the same pathology who underwent classical septoplasty without optical control. Dynamic observation was carried out before surgical treatment, on the 7th day, 1, 3, 6, 12 months after surgery. The aim of the research was to estimate the functional status of the mucous membrane of the nasal cavity after surgery, the time of the operation, as well as long-term postoperative complications if any. The following diagnostic measures there were: complaints, otorhinolaryngological examination by using endoscopic techniques, anterior active rhinomanometry on the Rinolan device (manufactured by Lana-Medica), measurement of mucociliary transport time using the saccharin test. Comparative analysis of groups of patients showed no significant difference in the restoration of nasal cavity functions. However, performing septoplasty using endoscopic technique reduces the time of surgery and the percentage of complications in contrast to the classical septum surgery
