The septum is approached by elevating the perichondrium flap; the various septal parts were dissected free and mobilized by chondrotomies, as required.
Technique consisted ofgiving injection of Transforming Growth Factor Beta 1, and subsequently performing ventral skin, ventral perichondrium, cartilage, and dorsal perichondrium excision, leaving behind only dorsal skin.
These grafts consist mostly of fascia of the temporal muscle, tragal perichondrium, tragal and conchal cartilage, periosteum, vein, adipose tissue, subcutaneous tissue, fascia lata, skin of the ear canal, and heterotopic skin tissue.
At this point, a generous piece of conchal cartilage is harvested and its perichondrium is removed.
From the superior edge, a full length incision of fascioperichondreal layer was carried out down to the perichondrium.
Given an outer fibrous perichondrium where type 1 collagen mRNA and protein are highly expressed and an inner, more cellular zone that cells are actively dividing (Price et al.
Various graft materials have been used since then including skin, amniotic membrane, mucous membrane, dura mater, cornea, periosteum, perichondrium, vein, adipose tissue and temporalis fascia.
This injury necessitates suturing of the anterior vocal ligament to the thyroid perichondrium to restore the normal scaphoid shape of the glottis (Table 2).
5 Other grafting materials like vein, fat, cartilage, perichondrium, placental membrane and homologus dura have been used.
There are several theories explaining heterotopic ossification mechanisms: 1) bone formation occurs because of the implantation of small particles containing osteogenic cells from the perichondrium or periosteum that are planted during a laparotomy or trauma; 2) bone formation is caused by differentiated stem cells in the mesoblast, as well as in the osteoblasts or chondroblasts, which result from local lesions, inflammatory processes, or infectious stimuli.
In previous studies, the temporalis fascia, tragal cartilage, tragal perichondrium, cortical bone graft, and silicone elastomer were used for resurfacing with satisfactory outcomes.
Furthermore, this end had articular hyaline cartilage with a thin perichondrium with the appearance of a secondary ossification centre (Figure 12).
