Abstract

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.
