Age features of bone tissue density in the posterior and inferior walls of the frontal sinus

Abstract

Chronic rhinosinusitis is a significant social, medical and economical problem. Elderly patients are unique among all groups of patients. The purpose of our study was to determine physiological variability of frontal sinus in the posterior and inferior walls and to compare it with variability in purulent-polypous rhinosinusitis. Subjects and methods: The study involved SCT examination of 40 male patients: 10 tomograms of patients aged 30–40 and 10 of patients aged 75–85. The tomograms of patients without ENT diseases were used for the control group. The study group included tomograms of patients aged 30–40 and 75–85 with chronic rhinosinusitis. Results. An average bone density of the posterior and inferior walls of the frontal sinuses was alculated. The bone density of the group aged 30–40 was 191.5±11.6 Hu in the inferior wall, 176.6±21 Hu in the posterior and 169.1±16.8 Hu and 164±21 Hu in the group aged 75–85 according to the above order. The study showed pronounced changes in the bone density in purulent-polypous frontal sinusitis. In the group aged 30–40 it was as follows: 120.1±8.3 Hu, 162.1±24 Hu in the inferior wall and 101.4±6.95 Hu, 127.4.8±15.4 Hu in the posterior wall. Conclusions: It can be assumed that the decrease in the bone density is associated with age. And it is more severe in case of chronic frontal sinusitis.
