ABSTRACT

Background: Laryngeal-tracheal stenosis is a complex disease with significant morbidity and mortality. It requires specialized training to develop effective skills for its surgical treatment, which includes various open or endoscopic procedures according to the degree of obstruction and the age of the patient. It has been shown the usefulness of animal models, as in the case of microvascular surgery training; to our knowledge, it does not exist an in vivo animal model for specific training in these types of laryngeal-tracheal procedures, which justifies its development.
Objective: To develop an animal model of training in basic external laryngealtracheal reconstruction techniques.
Material and methods: The swine model was chosen for the relative easy acquisition, the similarity in size and consistency to the human laryngeal-tracheal cartilage, particularly in young specimens. There were selected healthy pigs of four months of age, which under general anesthesia and tracheal intubation were monitored intra-operatively by the veterinarian assigned to the hospital facility while the tracheoplasty surgical procedures were carried out.
Results: In all the performed procedures the airway was rebuilt through endto- end anastomosis and expansion tracheoplasty.
Conclusion: This model is useful, because of the good approximation to the surgical anatomy, the surgical scenario, and because the development of the basic surgical skills required for the performance of these laryngealtracheal procedures.
