To enhance knowledge and understanding of the laryngeal framework maturation in different age groups and genders.
Cohort imaging study.
Tertiary academic referral center.
Computed tomography neck scans of 283 patients aged 8 to 20 years were studied. The interlaminae angle (ILA) of the thyroid cartilage at the level of the vocal folds, the anterior projection (angulation) of the thyroid cartilage (TC), and the degree of calcifications were evaluated and compared in sequential age groups of both genders.
Neck scans of 171 males and 112 females were reviewed. The average ILA was 76.45° ± 14.2 and 94.25° ± 10.2 for males and females, respectively (P < 10-25). In the female group, the mean angle was relatively constant (91-970) in all age groups, whereas in the male groups the angle decreased with age (920-670) (r = -0.9, P < 0.005) The most significant decrease was measured in the 14- to 15-year age group. The thyroid prominence was significantly more anteriorly angulated in males. The angle in the female age groups was constant (170.1°), and the angle in males decreased with age (161.47°) (P = 0.000008). Calcifications were more prominent at the posterior portion of the cartilage in both genders and increased with age.
Structural diversities of the TC begin in adolescent males because the thyroid cartilage grows anteriorly with a narrower ILA and with a greater anterior angulation. Our study shows that these changes, along with the degree of laryngeal cartilages calcification in both genders, occur as a continuum throughout puberty.
增强对不同年龄组和性别的喉框架成熟度的认识和理解。
队列影像学研究。
三级学术转诊中心。
对283例年龄在8至20岁的患者进行颈部计算机断层扫描研究。在声带水平评估甲状腺软骨的板间角（ILA）、甲状腺软骨（TC）的前突（角度）以及钙化程度，并在两个性别的连续年龄组中进行比较。
回顾了171例男性和112例女性的颈部扫描结果。男性和女性的平均ILA分别为76.45°±14.2和94.25°±10.2（P＜10-25）。在女性组中，所有年龄组的平均角度相对恒定（91-970），而在男性组中，该角度随年龄减小（920-670）（r = -0.9，P＜0.005），在14至15岁年龄组中下降最为显著。男性的甲状腺突出明显更向前成角。女性年龄组的角度恒定（170.1°），男性的角度随年龄减小（161.47°）（P = 0.000008）。两性中软骨后部的钙化更为明显，并随年龄增加。
TC的结构差异始于青春期男性，因为甲状腺软骨向前生长，ILA变窄且前突更大。我们的研究表明，这些变化以及两性喉软骨的钙化程度在整个青春期是连续发生的。
