EVALUATION OF THE CORRELATION BETWEEN THE CELL FRONTAL SINUS WITH DIAMETER OF FRONTAL SINUS OSTIUM OF THE CHRONIC FRONTAL SINUSITIS PATIENTS UNDERWENT ENDOSCOPIC SURGERY AT THE UNIVERSITY MEDICAL CENTER-HO CHI MINH CITY

Abstract

Background: Endoscopic frontal-sinus surgery remains as a very challenging technique with the potential for serious complications and even mortality. Determining the correlation of cells around the frontal recess with the diameter of the frontal sinus ostium helps to plan surgery and choose the appropriate frontal sinus exploration tool.

Objective: To evaluate the correlation between cells around the frontal recess with the anterior-posterior diameter of the frontal sinus ostium.

Method: Cross-sectional study.

Results: In 57 cases of frontal sinuses, Agger nasi cell were the most common (83.6%), supra Agger nasi cell presented in 32.7%; supra agger frontal cell in 3.6%. The supra bulla cell in 43.6%; supra orbital ethmoid cell in 40%; supra bulla frontal cell in 9.1%. The mean frontal ostium diameter was 7.36±2.07 mm. Classification of frontal sinus ostia in proportion were wide ≥10 mm in 10.5% of the cases; narrow in 75.4%; very narrow <5 mm in 14.03%.

Conclusion: In our study, it was noted that there was a correlation between the presence of cell groups behind the frontal sinus drainage tract such as supra-bulla cells, supra orbital ethmoid cells and the antero-posterior diameter of the frontal sinus ostia. There was no correlation between the presence of Agger nasi cell and the antero-posterior diameter of the frontal sinus ostia.
