    BackgroundTo compare the ultra percutaneous dilation tracheostomy (PDT) and mini open techniques (MOT) in randomized fixed and fresh cadavers. Assess degrees of damage to tracheal cartilage and mucosa via tracheal lumen and external dissection.MethodComparative cadaver study was performed, tracheostomy was placed in 36 cadavers (16 fixed, 20 fresh) from July 2004 to December 2004, in University of Alberta, Canada. PDT (size 7) were placed by intensivist and MOT (size 7) otolaryngologist. Both fixed and fresh cadavers were randomized. Evaluation was done according to gender, ease of landmark, mucosal and cartilage injuries.ResultsSignificant differences in mucosal injury (7 of 9 in UPDT VS 0 of 7 in MOT, p value 0.008), and cartilage injury (8 of 9 in UPDT VS 1 of 7 in MOT p value 0.012) were seen in fixed cadavers; and in fresh cadavers, mucosal injury (5 of 10 in UPDT VS 0 of 10 in MOT, p value 0.043), and cartilage injury (5 of 10 in UPDT VS 0 of 10 in MOT, p value 0.043).ConclusionsPDT resulted in severe damage to mucosa and cartilage, that might contribute to subglottic stenosis preventing decannulation. Considering the injury, MOT has better outcome than UPDT.
