Bilateral Perichondrium-Preserving Conchal Cartilage Harvest: A New Perspective to the Classic Procedure

Background:
To date, it has been a unanimous consent that the conchal cartilage is harvested at subperichondrial plane for the anterior side, and perichondrial level for the posterior dissection. This method has never been challenged, despite the fact that numerous studies already suggested the beneficial validity of preserving perichondrium. The authors address our technique of preserving both sides of the perichondrium during auricular cartilage harvest.
Methods:
Twenty patients, ranging in age from 18 to 33 years, completed the study. In all cases, the conchal cartilage was harvested with bilateral perichondrium preserved. The complications that arose were collected retrospectively.
Results:
The average time duration for the bilateral perichondrium-preserving was 37.6±4.1 minutes. The size of the conchal cartilage ranged from 3.1×2.4 to 1.8×1.5 cm. A case rendered small skin perforation during the harvest, but recovered uneventfully with immediate repair.
Conclusions:
The technique can be technically challenging and time-consuming. Nevertheless, better tissue integrity, balanced structure, and other potential benefits that ensue vindicate the extra time and effort. This bilaterally perichondrium preserved conchal graft warrants further validations in the long term.

01:17Gross Anatomy of Bone
The diaphysis is the tubular shaft that runs between the proximal and distal ends of the bone. The walls of the diaphysis are composed of dense and hard compact bone made of numerous osteons — the functional unit of the compact bone. The hollow region in the diaphysis is called the medullary cavity, which harbors the bone marrow. In infants and children, this marrow cavity is filled with red marrow, whereas in adults, it...
01:27Compact Bone
Compact bone, also called cortical bone, is the denser, stronger of the two types of bone tissue. It is found under the periosteum and in the diaphyses of long bones, where it provides support and protection. The microscopic structural unit of compact bone is called an osteon, or haversian system. Each osteon is composed of concentric rings of calcified...
01:27Fractures: Bone Repair
Minor fractures with no bone displacement are treated by immobilizing the fractured bone using a cast or splint. However, in the case of fractures with displaced bones, the broken bones are repositioned before immobilization to ensure successful healing without deformation and loss of function. The realignment of fractured bone ends is performed through a process called reduction. If the procedure...
