Tracheostomy in children causes approximately twice the mortality and morbidity as in the adult. The occurrence of complications correlates closely with the severity of the preoperative tracheal disease, the length of time the tracheostomy is needed, and the age of the patient. Morbidity documented in the postoperative period includes tracheal stenosis and collapsible anterior tracheal wall. The increased incidence of these problems in the pediatric patient may be related to the less rigid nature of the younger cartilage or to partial arrest of the normal tracheal growth rate, and may be aggravated by the style of tracheal incision used. Our study utilized weanling male ferrets in an effort to evaluate the possibly different response of growing, less resilient cartilage to different types of tracheal incision. Animals were randomized into three groups based on the type of incision used: inferiorly based trapdoor, vertical slit, or horizontal H. Endoscopic, radiographic, and airflow studies, as well as cross-sectional areas, were compared on all animals surviving tracheal cannulation for eight days and subsequent decannulation for seven days. Recommendations for pediatric tracheal incision are made on the basis of these studies.

Airway Dynamics

Flexible endoscopy is assuming a role of increasing importance in the evaluation and diagnosis of upper aerodigestive tract disorders. With improved fiberoptic capabilities and miniaturization, these techniques are gaining in applicability to the pediatric population. At Children's Hospital, Boston, a newly designed Machida 1.9-mm bronchoscope has been employed in the evaluation of the upper airway. The use of this small caliber instrument has been investigated in 1) evaluation of endotracheal or tracheotomy tube position, thus decreasing the need for repeated chest radiographs to confirm location; 2) bedside evaluation of possible tracheal disease (eg, mucous plug, granuloma, tracheitis) in the intensive care unit patient to determine treatment plans and/or need for further rigid bronchoscopy, and 3) evaluation of airway dynamics in the awake patient. Our experience with the flexible fiberoptic minibronchoscope is reviewed, with a discussion of indications for its use, as well as possible limitations. Case studies are presented to demonstrate the usefulness of the instrument.

Tracheobronchopathia Osteochondroplastica

A mature male grizzly bear ( Ursus arctos) that died of blunt-force trauma had numerous hard 1–3-mm nodules protruding from tracheal rings into the lumen of the distal trachea. Histologically, these were round aggregates of mature cartilage within the submucosa. Such lesions are consistent with tracheobronchopathia osteochondroplastica, a rare tracheal disease in humans and animals.

Tracheal Disease

The experience with laryngotracheal reconstruction in 20 children in Chicago is reviewed. Nine of the 20 children (45%) operated upon had congenital subglottic stenosis. Ten (50%) had acquired stenosis. One child was classified as having combined types. All patients underwent laryngotracheal reconstruction with autogenous costal cartilage grafts. Eight patients had both anterior and posterior costal cartilage grafts with stent insertion. One had a posterior costal cartilage graft only. Sixteen of the 20 children (80%) have been decannulated. Midtracheal or lower tracheal disease concomitant with laryngotracheal stenosis is an indication that endoscopic management of severe subglottic stenosis is likely to fail. Early laryngotracheal reconstruction is indicated for patients with a high likelihood of failure of endoscopic management and for those with severe cricoid cartilage deformities. Our results support the use of laryngotracheal reconstruction as an alternative to conservative (endoscopic) management of severe subglottic stenosis in carefully selected patients.

The aim of this study was to evaluate the tracheobronchoscopic, cytological and microbiological results of tracheal and bronchial collapse in dogs. In total, 8 dogs were included in the study. Clinically, tracheal palpations of the dogs were reflective of tracheal disease, and all dogs coughed on tracheal palpation. Vital parameters and hematological values of the dogs were within the normal ranges. Radiological views of the respiratory tracts and thorax were largely normal, but distinctive tracheal contours were noted in cases 3 and 6. Tracheobronchoscopy was performed under general anesthesia, and endoscopic findings (mucosal surfaces and color, prominent appearance of vessels, chondral ring abnormalities of the trachea, and the presence of bronchial and tracheal collapse) were scored. Bronchoalveolar lavage (BAL) was performed to collect samples for cytological and microbiological analysis. Five cases had tracheal collapse, and two cases had right bronchial collapse. Concurrent tracheal and right bronchial collapse were diagnosed in one case. Cytological results were not indicative of inflammation or infection, but Escherichia coli was isolated from case 2 (bronchial collapse) and case 3 (tracheal collapse). Antibiotic susceptibility results revealed that the organisms were susceptible to sulfamethoxazole/trimethoprim. Statistically, there were no significant differences between the cases in terms of total endoscopic scores. In conclusion, tracheal and/or bronchial collapse should only be diagnosed by tracheobronchoscopic examination. Cytological and microbiological analyses of the BAL fluid in these cases do not always provide valuable data for clinical practitioners. .
