Abstract
ABSTRACT: Cartilage-perichondrium composite graft is used in middle ear surgery for tympanic membrane, ossicular and for soft wall reconstruction. The thickness of the cartilage is thought to interfere with the sound conduction. In our otology practice for tympanic membrane reconstruction, we prefer the sliced cartilage graft to achieve acoustic benefit. At times in the process of slicing, the cartilage gets wasted if not sliced with a precision slicing instrument. We have designed and developed a multi-purpose cartilage slicer for precise reduction of the thickness of the cartilage. To describe the design of our cartilage slicer and to report our preliminary experience with the cartilage slicer. Descriptive study. The technique of slicing with our new cartilage slicer and its usage has been described in detail. A total number of 689 cartilages in tympanoplasty and mastoidectomy have been sliced with it from 2013 to 2017. Our study reports the technique of slicing the tragal cartilage for tympanoplasty, highlighting its advantages and precision of the cartilages slices obtained. Our cartilage slicer is a good option for cartilage slicing in tympanoplasty. LEVEL OF EVIDENCE: Level 4.
