Congenital tracheal stenosis: role of CT and high kV films.

Congenital tracheal stenosis is an intrinsic narrowing of the tracheal lumen due to complete cartilaginous rings. We evaluated the role of the chest radiograph, high kV films, CT and bronchoscopy in five patients with congenital tracheal stenosis. CT was superior to chest radiography and high kV films in the evaluation of the presence and extent of the stenosis. CT was superior to bronchoscopy in the evaluation of the distal extent of the stenosis in two patients. In addition, CT is useful in ruling out external compression of the trachea by a mass or associated vascular anomaly.

"Occult" posterior laryngeal cleft.

A previously undescribed deficiency of the posterior cricoid at the midline, wherein the mucosa overlying this deficiency is intact, is described. Clinically this presents as a variety of subglottic stenoses wherein the narrowing is primarily in the transverse subglottic diameter; the symptoms are, therefore, those of airway obstruction not laryngeal incompetence. It is suggested that this deformity has been previously overlooked by laryngologists and pathologists by virtue of a postmortem routine in which the larynx is routinely split in the posterior midline. Demonstration in these cases was by serial horizontal section of the intact, unsplit, whole larynx.

Coin ingestion: unusual appearance of the penny in a child.

The United States of America changed the composition of the penny in 1982. It is now a copper-plated, zinc-based coin. Erosions of the edge of this new coin were observed when it was impacted in the esophagus of a 13-month-old child.

Elliptical cricoid cartilage: a unique type of congenital subglottic stenosis.

An elliptically shaped cricoid cartilage, a specific type of congenital subglottic stenosis, is described, and the laryngoscopic and radiographic findings in three cases are discussed. An "hourglass" deformity of the subglottic laryngeal airway on an anteroposterior airway radiograph is suggestive of this diagnosis.

Postintubation granuloma of the anterior subglottic larynx.

We present an unusual case of a granuloma in the subglottic laryngeal airway of a 6-week-old infant with a history of previous endotracheal intubation. Postintubation granuloma formation in this region has not been previously reported in infants.

Efficacy of bronchoscopic carbon dioxide laser surgery for benign strictures of the trachea.

There have been conflicting reports in our literature concerning the efficacy of bronchoscopic carbon dioxide laser surgery for the treatment of benign strictures of the trachea. We have examined our experience in the management of this disease over a 2 1/2-year period; in all cases, our initial management was performed utilizing the rigid, ventilating bronchoscope with the universal endoscopic coupler and carbon dioxide laser. Eight of 14 patients were successfully managed in this study; retrospective analysis of our results revealed that the presence of one or more of the following four factors was extremely important in predicting an unfavorable prognosis of patients with tracheal stenosis managed endoscopically with the carbon dioxide laser: 1. loss of cartilaginous support; 2. stenosis length greater than 1 cm; 3. circumferential scarring; and 4. carinal involvement.

Tracheoplasty with pericardial patch for extensive tracheal stenosis in infants and children.

Five infants with long tracheal stenosis were operated upon by means of a pericardial patch tracheoplasty. The approach was through a median sternotomy with extracorporeal circulation for respiratory support. In four, the obstruction was due to complete rings; in the other, there was an associated tracheal trauma which had occurred during resuscitation. This patient requires prolonged stenting with a tracheostomy tube. All others are asymptomatic postoperatively, with the longest follow-up being 22 months. There were no deaths or infections. We conclude from this experience that median sternotomy provides an excellent approach to the trachea, that autogenous pericardium is advantageous, and that there is no need for prolonged tracheal stenting in most patients.

Histopathology of congenital subglottic stenosis.

Three patients with congenital subglottic stenosis are presented and whole organ serial-section studies of their larynges are discussed. A superiorly displaced first tracheal ring is observed to form a cartilaginous subglottic stenosis in one. This "trapped first ring" is demonstrated in horizontal, sagittal and coronal planes. Subglottic stenosis is a clinical diagnosis which describes multifarious histopathological forms of narrowing within the subglottic larynx.
