Цель исследования – выявить частоту встречаемости, размеры и локализацию септ в области нижней стенки верхнечелюстной пазухи при наличии боковыхзубов верхней челюсти.Материалы и методы. Проанализированы данные конусно-лучевой компьютерной томографии (КЛКТ) 150 пациентов (295 верхнечелюстных пазух).Результаты. Костные перегородки верхнечелюстной пазухи были идентифицированы у 43,3 % пациентов в области нижней стенки 98 из 295 пазух (33,2 %).Большинство септ (112 из 122) располагались вертикально во фронтальной плоскости (медиально-латерально). В 49,2 % случаев они обнаруживались в областипервого и второго верхних моляров. Протяженность септ варьировала от 2,5 ммдо 17,31 мм (6,58 ± 3,18 мм). Полные септы, разделяющие пазуху на относительноизолированные участки, обнаружены в 19,4 % случаев.Заключение. Установление с помощью КЛКТ топографии септ в области нижней стенки верхнечелюстной пазухи на этапе планирования открытого синуслифтинга должно способствовать снижению интра- и послеоперационных осложнений этой операции.

TOPOGRAPHY OF SEPTA
inus septa in patients with a dentate posterior maxilla.Materials and methods. The data of cone-beam computed tomography of 150 dentalpatients (295 maxillary sinuses) were analyzed.Results. Maxillary sinus septa were identified in 43.3 % of patients inside 98 of 295 sinuses (33.2 %). The most common orientation of septa was medio-lateral for a numberof 112 from 122 (91.8 %). Septa were most common (49.2 %) in the region of the firstand second maxillary molars. The mean size of septa was 6.58 ± 3.18 mm (range 2.5–17.31 mm).Complete septa (dividing the sinus into two relatively separated cavities) were identifiedin 19.4 % of cases.Conclusion. Detection of the topography of maxillary sinus septa by using cone-beamcomputed tomography is essential when planning sinus augmentation procedures in orderto avoid unnecessary intra- and postoperative complications
