Forty-eight cases of tracheal agenesis have been reported to date. Previous authors have studied gross postmortem laryngeal specimens. Of 37 cases wherein laryngeal findings were mentioned, only 14 were reported to be abnormal. This report details two more cases of tracheal agenesis and includes a detailed histopathologic study of the laryngeal anomalies by serial horizontal section. Although one of these specimens appeared normal at autopsy, both were found to have several abnormalities when studied microscopically in horizontal section. Both have an elliptical cricoid cartilage, an abnormality originally discovered by one of us (G.F.T.) using the same technique.
