Measuring the anterior skull base dimensions (length and width) endoscopically in Vietnamese cadavers and finding the correlation between them. Methods: Ten Vietnamese adult cadavers were dissected endoscopically. Anatomical dimensions of the anterior skull base were measured such as anterior skull base length (posterior table of frontal sinus to planum sphenoidale) and width (orbit to orbit) at the level of the anterior ethmoidal artery (AEA), posterior ethmoid artery (PEA) and the anterior wall of the sphenoid sinus. Results: The average length of anterior skull base is 32,33±4,72mm. The width at the level of AEA, PEA and anterior wall of the sphenoid sinus are 23,75±1,42mm; 25,90±2,70mm and 26,85±1,66mm, respectively. These dimensions are greater in male than female cadavers. The average width at AEA is the shortest and at the anterior wall of the sphenoid sinus is the longest. There is a tight correlation between the skull-base length and width at the level of AEA. Conclusions: Identifying the bounderies of anterior midline skull base endoscopically and protecting medial orbital wall and the optic nerve are important for safe surgery. Endoscopic measurement of the anterior midline skull base dimensions can be useful in reconstructing anterior skull base defects and estimating the anterior skull base window size in anterior cranial fossa tumors resection.
