Evaluation and Management of Congenital Laryngeal Anomalies
نویسنده
چکیده
The infant larynx differs from that of the adult in more ways than size alone . Its position in the neck is more cephalad than in the adult. The thyroid notch positioned high, posterior to the hyoid bone, the bone obscuring the thyroid notch as a landmark for tracheotomy. The epiglottis has an omega shape and may be somewhat tubular . The cuneiform cartilages, arytenoids, and posterior supraglottic soft tissue are of relatively large size. Of particular interest, as in the adult, the cephalad portion of the cricoid cartilage is V-shaped, not circular.
