Abstract
OBJECTIVES: Extensive tracheal airway defects represent a clinical dilemma. Although resection and reanastomosis and staged tracheoplasty may prove beneficial in some cases, recurrent or extensive circumferential stenosis remains a reconstructive challenge. We report the use of the allograft tracheoplasty technique for the reconstruction of recurrent, extensive defects of the trachea and cricoid. METHODS: Nine consecutive patients with recurrent tracheal stenosis were treated with the two-stage allograft tracheoplasty technique. A retrospective review was performed to evaluate for prior surgery, length of stenosis, surgical technique, and outcome. All 9 patients underwent multiple surgical procedures for acquired tracheal stenosis (average, 3.4 procedures) before undergoing the allograft tracheoplasty technique. Before surgery, all patients were tracheotomy-dependent. RESULTS: The patients were assessed 8 to 39 months after allograft tracheoplasty. The primary airway disorders included postintubation stenosis (n = 6), surgical resection for malignancy (n = 1), and idiopathic stenosis (n = 2). Three defects involved 30% to 60% of the cricoid cartilage, and 4 defects were complete circumferential tracheal defects. Five patients underwent an island deltopectoral flap for closure of the tracheoplasty site. One patient had a superficial wound infection at the cartilage recipient site, and 1 patient had a hematoma at the deltopectoral flap donor site. All 9 patients were successfully decannulated without shortness of breath, stridor, or recurrent stenosis at the time of follow-up. CONCLUSIONS: Allograft tracheoplasty is a new technique for the reconstruction of recurrent tracheal stenosis. It appears to be reliable for extensive airway defects that are refractory to conventional tracheoplasty techniques.
