Evaluation of the Distance Between Anterior Commissure of True Vocal Folds and the First Tracheal Ring and Related Laryngeal Indices in 40 XXXX Cadavers.

@entity825 @entity1 @entity8276
OBJECTIVE: Distorted anatomy in laryngotracheal pathologies expresses the need to determine a quantitative mean of the distance between the anterior commissure of true vocal folds and the first @entity8276 to better define whether a lesion is in the subglottis or has extended toward the @entity825 . STUDY DESIGN: This is a descriptive cross-sectional study. METHODS: In 40 cadavers, the larynx was exposed with an apron cut. The laryngofissure cut opened the larynx via the lateral aspect so that the anterior commissure was exposed. A needle was passed through the thyroid cartilage to reach the anterior commissure. The second needle was crossed over the first @entity8276 . The distance between the two needles was measured. RESULTS: The mean distance between the anterior commissure of true vocal folds and the first @entity8276 was 26.82      4.28  mm (21.3-42.5  mm) in our subjects. This distance was 27.27      4.45 and 25.05      3.2  mm, in @entity1 and @entity1 , respectively. There was no statistically significant correlation between this distance with body mass index (BMI), age, and sex. CONCLUSIONS: The distance between the anterior commissure and the first @entity8276 in @entity1 with laryngotracheal pathologies helps in determining the best therapeutic plan for @entity1 .
