In one report, in the grafting of perichondrium
femurotibial joint in 30 rabbits, the growth of new cartilage in continuous passive movement was better than fixation .
The posterior approach minimizes visible scars and postoperative contour deformities and allows the harvest of perichondrium
and soft tissue at the same time to use as a thin onlay graft.
The lack of perichondrium
or periosteum in the area of insertion of the AC tendon may allow invasion of tumors into the laryngeal skeleton.
A microscope provided accurate surface assessment of the extent of the tumor, and the tumor was resected, including the entire true vocal fold, all the adjacent tissue, and the internal perichondrium
of the thyroid cartilage (figure 1, B).
A layer of perichondrium
was then placed over the bone wax and promontory to provide further reinforcement of the complete round window occlusion (figure 4, C).
4) Cocaine use also causes structural compromise, via vasoconstriction-mediated necrosis of the perichondrium
and subsequent chondrocyte death (5)
The skin and perichondrium
of the upper and middle thirds of the antihelix were resected.
The hemorrhage in this case resulted from manipulation within the paraglottic space, perhaps from trauma to the inner perichondrium
of the thyroid cartilage.
Appropriate management of a nasal hemangioma involves wide resection of the lesion and the underlying mucosa and perichondrium
with ligation or cautery of the feeding vessels.
If the eardrum is atrophic, be prepared to repair it at the time of surgery by reinforcing the drum with fascia, perichondrium
, or a vein graft.
The graft was sutured to the masseter muscle anteriorly, to the zygomatic arch superiorly, to the sternocleidomastoid muscle posteroinferiorly, to the tragal perichondrium
preauricularly, and to the mastoid periosteum postauricularly.
Chronic injury to the perichondrium
and failure to correct the causative factors can lead to recurrence.
