The objective of the work is to improve the efficacy of the reparative processes of the nasal mucosa after septoplasty and submucosal vasotomy of inferior turbinates by applying 0.9% sodium chloride solution cavitated by a low-frequency ultrasound. The study involved 50 patients with septum deviation and vasomotor rhinitis. In all cases, septoplasty and submucosal vasotomy of the inferior turbinates were performed simultaneously. In the control group, we used standard postoperative treatment: antibiotic therapy, irrigation of the nasal cavity with seawater isotonic solution, nasal toilet. The nasal cavity of the main group patients was irrigated with 0.9% sodium chloride solution, cavitated by low-frequency ultrasound, starting from the 2nd post-operative day. Assessment of the nasal mucosa condition was performed on the 2nd and 14th days after the surgery by means of endoscopic examination, determination of transport, excretory, absorbent functions of the nasal mucosa, cytological examination, and anterior active rhinomanometry. In the course of the study, it has been found that irrigation of the nasal cavity with 0.9% of sodium chloride, cavitated by low-frequency ultrasound, provides stimulation of the reparative processes in the nasal mucosa and, as a result, shortens the rehabilitation period.
