This article presents a clinical case of a patient with a combined pathology: a deviated nasal septum, severe obstructive sleep apnea syndrome, and distal occlusion, skeletal class II, microgenia. A step-by-step treatment was performed: the first stage involved septoplasty with correction of intranasal structures to restore nasal breathing, followed by orthodontic treatment using split therapy (selection of a custom-made mouthguard for nighttime wear) to normalize occlusion and upper airway patency. Combined treatment resulted in significant improvement in nasal breathing and normalization of polysomnography parameters (a decrease in AHI). This article presents objective methods for assessing nasal breathing and OSA (AHI) dynamically after comprehensive treatment. The importance of an interdisciplinary approach involving an otolaryngologist, orthodontist, and somnologist is emphasized.
