| tracheobronchial diverticulum | The endodermal lung primordium which will give rise to the epithelial lining of the respiratory tract. Synonym: lung bud. (05 Mar 2000) |

| tracheobronchial dyskinesia | Degeneration of elastic and connective tissue of bronchi and trachea. (05 Mar 2000) |
| tracheobronchial groove | The depression in the floor of the caudal end of the pharynx, continued downward on the ventral wall of the foregut; from it are developed the lower part of the larynx and the trachea, bronchi, and lungs. Synonym: tracheobronchial groove. (05 Mar 2000) |
| tracheobronchitis | Inflammation of the mucous membrane of the trachea and bronchi. (05 Mar 2000) |
| tracheobronchomegaly | A rare and probably congenital condition characterised by great enlargement of the lumen of the trachea and the larger bronchi. (12 Dec 1998) |
| tracheobronchopathia osteochondroplastica | <radiology> Osteocartilaginous nodules within submucosa of trachea with or without bronchi, arise from cartilage rings, posterior membranous trachea spared (Differential diagnosis: amyloidosis), incidence debated; 1/3000 in autopsy series, aetiology unknown (carcinoma and P normal), but most accepted theory is an exaggerated response to chronic inhalation of irritants, most cases in adults greater than 50 yrs old (youngest patient age 2 yrs), M:F = 3:1, dyspnea, productive cough, haemoptysis findings: CXR: nodules in trachea with or without calcification, CT: as above, but more sensitive to calcification and better at demonstrating lack of posterior tracheal involvement (12 Dec 1998) |
| tracheobronchoscopy | Inspection of the interior of the trachea and bronchi. Origin: tracheo-+ bronchus, + G. Skopeo, to view (05 Mar 2000) |
| tracheocele | <medicine> Goiter. A tumour containing air and communicating with the trachea. Origin: Gr. The windpipe + a tumour: cf.F. Tracheocele. Source: Websters Dictionary (01 Mar 1998) |
| tracheoesophageal | Relating to the trachea and the oesophagus. (05 Mar 2000) |
| tracheoesophageal fistula | A congenital anomaly where the upper oesophagus ends (atresia) and does not connect with the stomach and the lower oesophagus connects to the trachea (tracheoesophageal fistula). A common complication seen shortly after birth is an aspiration pneumonia. Infants will demonstrate excessive salivation, gagging and coughing with feeding, poor feeding and a bluish discolouration to the skin (cyanosis). Treatment involves the surgical repair of the oesophagus before the child can take anything by mouth. (27 Sep 1997) |
| tracheoesophageal puncture | A small opening made by a surgeon between the oesophagus and the trachea. A valve keeps food out of the trachea but lets air into the oesophagus for oesophageal speech. (12 Dec 1998) |
| tracheoesophageal speech | A form of alaryngeal speech obtained by a surgical technique which creates a shunt between trachea and oesophagus, allowing pulmonary air to generate upper oesophageal and pharyngeal mucosal vibrations as a substitute for vocal cord vibrations when the larynx is surgically removed. (05 Mar 2000) |
| tracheolaryngeal | Relating to the trachea and the larynx. (05 Mar 2000) |
| tracheomalacia | Degeneration of elastic and connective tissue of the trachea. Origin: tracheo-+ G. Malakia, softness (05 Mar 2000) |
| tracheomegaly | An abnormally dilated trachea which may, like bronchiectasis, result from infection or prolonged positive pressure ventilation. Origin: tracheo-+ G. Megas (megal-), large (05 Mar 2000) |
