Evaluation of Anatomical Variations of the Nasal Cavity and Ethmoidal Complex on Cone-Bone Computed Tomography.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Background: Anatomical variations of the nasal cavity and ethmoidal complex, though often asymptomatic, may influence nasal airflow, sinus drainage, and the development of sinonasal disorders. Accurate imaging is crucial for diagnosis and surgical planning. This study aimed to assess the prevalence and types of anatomical changes in the nasal cavity and ethmoidal complex using cone-beam computed tomography (CBCT). Materials and Methods: A cross-sectional observational study was undertaken with 300 adult patients' CBCT scans. Variations examined included septal deviation, concha bullosa, enlarged Nasi cells, Haller cells, Onodi cells, and anomalies of the uncinate process and turbinates. Results: Nasal septal variations were found in 56% of patients, with single deviations (18.3%) and deviation with spurring (11.0%) being the most common. Concha bullosa was most common in the middle turbinate (88.7% right, 91.3% left), with the lamellar subtype predominate. In 94.0% of instances, inferior turbinate hypertrophy was seen, with Onodi cells accounting for 32.0% of ethmoidal air cells. Other variations were Haller cells (17.7%) and Aggre Nasi cells (10.3%). Conclusion: It was concluded that anatomical differences in the nasal cavity and ethmoidal complex are widespread and have therapeutic implications. In otolaryngology and maxillofacial practice, CBCT is an invaluable imaging tool for detailed assessment, improving diagnostic accuracy, and assisting with surgical planning.
