The Bony Cartilaginous Unit

Surgery of the Bony and Cartilaginous Vault in Rhinoplasty

An osteotomy must be performed in almost all types of external nose correction. By mobilising the bony skeleton, the nose may be sculpted into the desired shape and position. The osteotomy is carried out as gently as possible in an effort to minimize postoperative swelling and soft tissue bleeding. Finger and sharp chisels are used. Nasal bones are accessed through a short intercartilaginous in...

The Cardiovascular and Neurotoxic Effects of the Venoms of Six Bony and Cartilaginous Fish Species

Fish venoms are often poorly studied, in part due to the difficulty in obtaining, extracting, and storing them. In this study, we characterize the cardiovascular and neurotoxic effects of the venoms from the following six species of fish: the cartilaginous stingrays Neotrygon kuhlii and Himantura toshi, and the bony fish Platycephalus fucus, Girella tricuspidata, Mugil cephalus, and Dentex tumi...

How accurate is 18F-FDG-PET-CT in determining local cartilaginous/bony involvement by head & neck malignancy?

Results PET-CT scans demonstrated increased abnormal osseous uptake in 63 cases, of which 52 were true osseous invasion, but 11 were false-positive (4 due to osteoradionecrosis, 4 benign dental infection/inflammation, 3 over-staging due to intense FDG-uptake nearby the bone). 708 cases were reported as ‘no osseous uptake’, of which 704 were truenegative, but 4 were false-negative (2 due to intr...

Pulmonary hamartoma (the cartilaginous type).

Myelin in cartilaginous fish

Myelin is probably one of the most fascinating and innovative biological acquisition: a glia plasma membrane tightly wrapped around an axon and insulating it. Chondrichthyans (cartilaginous fishes) form a large group of vertebrates, and they are among oldest extant jawed vertebrate lineage. It has been known from studies 150 years ago, that they are positioned at the root of the successful appe...
