Laryngomalacia and Tracheomalacia — Diagnosis and Treatment
ثبت نشده
چکیده
Laryngomalacia is a congenital condition that is characterized by the abnormal development of supraglottic structures, such as the epiglottis. The supraglottic structures tend to collapse during inspiration, causing stridor and, in severe cases, hypoxemia. Tracheomalacia is a more serious condition of abnormally developing tracheal cartilage that is characterized by tracheal lumen collapse duration expiration.

Results: A total of 54 patients underwent MDO and of those 21 patients were found who have undergone both MDO and DLB. The incidence of at least 1 SAL was 71.4% in this group. A subgroup of patients less than 24 months had an incidence of SALs that was 78%. Types of SALs encountered include laryngeal edema (57.1%), tracheobronchitis (42.9%), laryngomalacia (33.3%), tracheomalacia (14.3%), bronc...
متن کاملSynchronous airway lesions in laryngomalacia.
OBJECTIVE Laryngomalacia is the most common cause of congenital stridor. Laryngomalacia may be associated with other structural and functional airway lesions. While previous studies suggested a 10-45% rate of synchronous airway lesions (SALs), the exact rate and it's clinical significance is unknown. The purpose of this study was to determine the prevalence of SALs below the glottic level in co...
