Abstract

Background: In endoscopic sinus surgery, procedures involving the frontal recess are considered particularly challenging due to its narrow dimensions, complex anatomical relationships, and limited endoscopic visualization. A thorough understanding of the drainage pathways and their anatomical associations with frontal recess cells, including the Frontal cell, is essential for safe and effective surgical intervention. Wormald's modified classification provides a clinically practical and relatively comprehensive framework for assessing these anatomical variants. This study aimed to assessment of frontal cells on computed tomography imaging of the paranasal sinuses. Methods: A descriptive cross-sectional study was conducted on 346 frontal recesses from 177 patients who underwent computed tomography imaging of the paranasal sinuses at Nhan dan Gia Dinh Hospital between December 2024 and May 2025. Results: Of the 177 patients included in the study: 66.1% were female and 33.9% were male, the overall prevalence of Frontal cells was 45.95%. Specifically, Type 1 (K1) accounted for 26.3%, Type 2 (K2) for 10.12%, Type 3 (K3) for 8.67%, and Type 4 (K4) for 0.87%. The presence of the Agger Nasi cell showed a statistically significant difference between the group with Frontal cells and the group without Frontal cells, with an odds ratio (OR) of 5.42 and p < 0,001. Conclusions: The assessment of the presence and classification of Frontal cells based on Wormald's modified classification using computed tomography of the paranasal sinuses is essential in clinical practice. The presence of Frontal cells is significantly associated with frontal sinusitis.
