Bjork Flap

In 1952, Bjork created an inferior based tracheal flap through 2nd, 3rd and 4th tracheal ring which was later fixed to skin to secure the lumen of a tracheotomy tube. [1] Following this Bjork flap, many studies came which cited various complications or drawbacks for this flap. However, various studies have also reported no added risk and absence of complications associated with this. A recent good systemic review on bjork flap by Au et al. [2] searched all MEDLINE data from database inception to march 2016 for contemporary reviews on this flap. This review compared all relevant studies related to Bjork flap like by Malata, Hammarfjord et al. [3,4] retrospective review by the Dukes as well as a prospective cohort study of Lulenski on Bjork flap. It suggests that Bjork flap tracheostomy can be performed with minimal complications, however, it also questions the strength of previous studies comparing Bjork with incisional or excisional window tracheostomies.
