BACKGROUND
Cartilage-perichondrial grafts are often used for tympanic membrane and middle-ear reconstructions. Tragal and conchal cartilages are most frequently used for this purpose. Studies have shown that slicing the cartilage to less than 0.5 mm thickness improves acoustic benefit. However, the thickness of the cartilage in a given population may not be uniform.
OBJECTIVE
This descriptive cross-sectional study aimed to determine the average thickness of tragal cartilage (in terms of age and sex) in an Indian population.
METHOD
A prospective study of 61 tragal cartilages harvested during serial tympanoplasty and modified radical mastoidectomy were analysed according to thickness.
RESULTS
The total average thickness of tragal cartilage was 1.228 ± 0.204 mm in males and 1.090 ± 0.162 mm in females. The overall thickness was 1.018 ± 0.139 mm in those aged less than 15 years, 1.139 ± 0.238 mm in those aged 15-30, and 1.189 ± 0.155 mm in those aged over 30 years.
CONCLUSION
The findings help us to determine age-related cartilage thickness for slicing techniques in tympanoplasty.
背景
软骨-软骨膜移植物常用于鼓膜和中耳重建。耳屏软骨和耳甲软骨最常被用于此目的。研究表明，将软骨切成厚度小于0.5毫米可改善声学效果。然而，特定人群中软骨的厚度可能并不均匀。
目的
这项描述性横断面研究旨在确定印度人群中耳屏软骨的平均厚度（按年龄和性别）。
方法
对在连续性鼓室成形术和改良乳突根治术中获取的61块耳屏软骨进行前瞻性研究，并根据厚度进行分析。
结果
男性耳屏软骨的总平均厚度为1.228±0.204毫米，女性为1.090±0.162毫米。15岁以下人群的总体厚度为1.018±0.139毫米，15至30岁人群为1.139±0.238毫米，30岁以上人群为1.189±0.155毫米。
结论
这些发现有助于我们确定鼓室成形术中切片技术与年龄相关的软骨厚度。
