Preclinical Evaluation of a Modified Surgical Approach to the Maxillary Sinus – Comparison of two Endoscopic Techniques |Biomedgrid

Purpose: There are several approaches to the maxillary sinus for the treatment of pathologies. The endoscopic technique is the gold standard in paranasal sinus surgery. The middle meatal maxillary antrostomy (MMMA), which is the enlargement of the natural opening, is the most common method. The prelacrimal recess approach (PLRA) is known as an alternative method. However, advantages of either method have not been systematically assessed.
