Estenosis laringotraqueal: Experiencia clínica

introduction: laryngo-tracheal stenosis is a condition difficult to manage and obtain results which permit the person who suffers it recover phonorespiratory and deglutory function. this is not always pssible to achieve. aim: present a clinical series of patients with stenosis of the vas and underwent surgery. a secondary objective is to assess whether or not there are similar technical differences between age groups. material and method: we present a retrospective analysis of patients surgically treated by the authors. they present demographic description cases, site of stenosis, type of intervention according to age; percentage of successful decannulation after one or more interventions; reoperation, type of graft and stents used. the group was divided into pediatric and adult. statistical analysis was performed with χ2 and fisher. results: the case mix consists of 88 patients who underwent surgery to repair laryngo-tracheal stenosis. children under 18 years correspond to 45 cases (51%%). the percentage of success in the first surgery is 75.6%% (34/45 cases) in children under 18 and 76.7%% (33/43 cases) over 19years. 15/21 failed cases were reoperated in the first instance; 13 of them were decannulated increasing success to 90.9%%. reoperation failure and still unresolved, 8 cases. surgical technique used was laryngotracheal reconstruction with costal cartilage graft either anterior or posterior being subglottic the site of stenosis. success rate to this technique is 68.3%%. in patients under 18 years old is 71%% success and over 18 years 60%%. for tracheal stenosis, tracheal resection with end to end anastomosis has a success rate of over 90% and it is performed mostly in the age group over 18 years. conclusion: we obtained success rates in decannulation similar to those reported internationally. a complex stricture remains a challenge to achieve its decannulation. in these cases combined resections and reconstructions are used.
