Asymmetry of the anterior ethmoidal artery in relation to the anterior skull base: a population-based study of 500 arteries.

Objective: To analyze variability in the distance between the Anterior Ethmoidal Artery (AEA) and the anterior Skull Base (SB), as well as the frequency of lateral asymmetry in a Latin American population using computed tomography.

Methods: A total of 250 computed tomography scans of paranasal sinuses in coronal reconstruction (500 AEAs) were analyzed. After determining the image with the best anatomical view of the artery, the distance between its midpoint and the ethmoidal roof was measured, and the images were independently interpreted by 2 physicians.

Comparison between endoscopic and microscopic butterfly cartilage graft inlay tympanoplasty: a systematic review and meta-analysis.

Purpose: The purpose of this study was to compare the effectiveness of endoscopic and microscopic approaches for butterfly cartilage graft inlay tympanoplasty regarding anatomical and hearing outcomes through a systematic review and meta-analysis.

Methods: A search of PubMed, Embase, MEDLINE, and Virtual Health Library was performed from inception to July 3rd, 2021, using keywords, such as tympanoplasty, cartilage graft, and inlay technique. Data from articles that met inclusion criteria were extracted by two authors independently.
