KHẢO SÁT ĐẶC ĐIỂM TẾ BÀO HALLER TRÊN PHIM CT SCAN MŨI XOANG TẠI BỆNH VIỆN NHÂN DÂN GIA ĐỊNH

Abstract

Background: Infraorbital ethmoid cells (Haller cells) are pneumatized anterior ethmoid air cells extending into the orbital floor and the roof of the maxillary sinus, located near the maxillary ostium and ethmoidal infundibulum. Evaluating Haller cells on paranasal sinus CT scans plays an important role in diagnosis, treatment planning, and guiding endoscopic sinus surgery. This study aimed to assess the morphological characteristics of Haller cells on paranasal sinus CT scans. Methods: A cross-sectional descriptive study was conducted on 151 patients who underwent paranasal sinus CT scans from August 2024 to June 2025 at Nhan dan Gia Dinh Hospital. Each case was assessed for the number of Haller cells. Cell shape was classified according to the criteria by Pallavi Kamdi, and cell size was categorized following the classification by Mathew. Results: Haller cells were identified in 47.0% of patients. The most common shape was oval (58.6%), and the majority had medium to large sizes (2mm to > 4mm, accounting for 87.9%). Conclusion: Haller cells are a common anatomical variant with characteristic morphological features. Their evaluation on paranasal sinus CT scans offers practical value in assessing anatomical variations and supports clinical decision-making and appropriate surgical planning.
