2011) created rabbit ear hypertrophic scar models by removing skin and perichondrium
palisade cartilage tympanoplasty, composite shield graft, perichondrium
island graft, etc.
sup] In previous studies, the temporalis fascia, tragal cartilage, tragal perichondrium
, cortical bone graft, and silicone elastomer were used to resurface the canal defect with most satisfactory outcomes.
Direct blunt trauma or continuous abrasion of the pinna might bring about accumulation of blood and serum in the space between perichondrium
and cartilage (3-6); this hematoma might lead to cartilage necrosis through reduction of blood flow into the tissue (7).
However, when they removed rib cartilage but left its perichondrium
, the missing sections entirely repaired within one to two months.
Result: Inappropriate size or location of the implant material were defined in two subjects, inappropriate management of the inner perichondrium
of thyroid lamina (IPTL) were defined in 5, and cricoarytenoid joint (CAJ) fixation in one.
There is a risk of injuring the supporting mucosa and perichondrium
Various autogenous tissues such as temporal muscle and fascia, fascia lata, cartilage, dermis, full thickness skin, perichondrium
, rib, metatarsal, sternoclavicular and ulnar heads have been used as interpositional materials.
The study revealed arteriolar narrowing in perichondrium
region of pinna most remote from arterial blood supply, i.
Synthetic dural graft (Surgisis(a) Biodesigr[TM] Dural Graft, REF G31092, made in the United States) was placed on the perichondrium
, leaving it covered by the upper and lower mucosa flaps.
The reasons include embryologic fusion planes, insufficient margins because of concern regarding nasal deformity, and a tendency to fan-out and spread but rarely to invade the perichondrium
62-68) Optical coherence tomography imaging of the normal bronchial wall (Figure 4, A through E) reveals the fine, layered features of the airway, including the epithelium, basement membrane, lamina propria, salivary-type glands and ducts, vessels, and cartilage with surrounding perichondrium
