ABSTRACT

One of the most challenging problems in head & neck surgeon is the management of tracheal stenosis. Many reports have been published about reconstructive procedures using various materials which substitute for the tracheal wall. Since Caputo and Consiglio used the patient's own auricular cartilage to repair deficiency of the tracheal wall in 1961. Autogenous auricular cartilage graft has been accepted because it was easily accessible by ENT surgeon and augmented the tracheal lumen due to its concave curvature. The autogenous auricular cartilage grafts were transplanted to the window defects in the cervical tracheas in 8 adults cats. No repiratory symptom appeared during the observation time of 2 to 8 weeks. The reconstructed tracheal lumen of all cats showed the minimal scarring without stenosis. There were no evidence of cartilage resorption and intact chondrocytes persisted in all. All specimens showed mucosal regeneration over the grafted segment with principally non-ciliated cuboidal epithelium early, but 8 wks later, with ciliated columnar epithelium. Based on this animal experiment, the authors applied this method on 3 patients in February, and March, 1984. They were two cases of tracheal stenosis resulted from tracheostomy and one subglottic case resulted from endotracheal intubation. Respiratory symptoms were relieved after operation in each case. Tracheal lumen was successfully augmented by this procedure. We concluded that this method was one of the excellent ways for the treatment of tracheal stenosis.
