A platinectomy was performed via a transcanal approach, and the incus was removed, molded, and replaced between the malleus and the oval window, with interposition of a piece of tragal 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
Takanori Takebe at Yokohama City University in Japan is the first to confirm that the ear contains a source of stem cells, hidden in tissue called the perichondrium
Mesenchymal stem cells in perichondrium
express activated leukocyte cell adhesion molecule and participate in bone marrow formation.
Laryngeal tissue is comparable to tracheal tissue, except for the vocal cords; the outer layer of the vocal cords consists of perichondrium
and connective tissue, and the inner layer contains cartilage covered with mucosal epithelium consisting mainly of pseudostratified ciliated cells.
This cartilage is hyaline and without perichondrium
Traditionally, a combination of bone dust, fat, temporalis fascia, perichondrium
and bone wax are used to repair the fistula.
A clinical and histopathological study by Greisz and colleagues (4) found that complications from this procedure were few and found slight inflammation of the perichondrium
Femora with the perichondrium
removed failed at a mean peak torque of 18.
The first of two volumes, the volume comprises three sections: (1) insights into skeletal development, including, among others, novel ideas about the role of the perichondrium
in skeletogenesis, current studies on joint formation, and the human consequences of dysregulated morphogenic signalling; (2) a traditional series of papers, both reviews and original research articles on bone cells - osteoblasts, osteoclasts, and osteocytes - in relation to mechanisms underlying their formation, fate, and function; and (3) new information on the role of hormones, both steroids and peptides, as well as cytokines and the central nervous system in regulating skeletal remodelling.
The lesion was removed entirely, but the perichondrium
was not exposed.
Microscopically, the cartilage cap is invested by perichondrium
and composed of hyaline-type cartilage with clustered chondrocytes embedded in an abundant matrix.
