A cartilage conserving concept of a surgical tracheostomy-introduction and analysis of safety and complications of the Visor-tracheostomy-a retrospective monocentric comparative study over 8 years

Introduction For decades, surgical tracheostomy using a Bjoerk-flap has been the standard procedure to create a reliable epithelialized tracheostomy in head and neck tumour surgery. This technique is being used as the gold standard approach in every surgical subspecialty. Preparation of the Bjoerk-flap requires splitting one or two tracheal rings, causing potential tracheal instability and tissue trauma. As a surgical alternative, the Visor-tracheostomy allows creating an epithelialized tracheostomy without splitting tracheal rings. This work aimed to prove the safety of the Visor-tracheostomy method, due to peri- and early postoperative complications. Methods We present a step-by-step approach of this "new tracheostomy method". Monocentric, retrospective data within 8 years were evaluated. Complications such as wound infection, tracheostoma bleeding, tracheostoma dehiscence, and via falsa in a total of 453 tracheostomies (161 Bjoerk-flap and 292 Visor-tracheostomies) were compared and the results were analysed descriptively. Results Our data did not reveal a statistically significant difference in risk for a complication between the two methods (Visor-tracheostomy vs. Bjoerk-flap; p = 0.60; OR = 1.26, 95%-CI 0.60-2.82). This supports the hypothesis that applying the new cartilage conserving Visor-tracheostomy does not result in a reduction of safety for the patient. Conclusion We contend, that the Visor-tracheostomy has the potential to supersede other surgical tracheostomy techniques in some indications.
