The function of some dermal bone is conserved throughout vertebrates, although there is variation in shape and in the number of bones in the skull roof and postcranial structures. In bony fish, dermal bone is found in the fin rays and scales. A special example of dermal bone is the clavicle. Some of the dermal bone functions regard ...
Indirect fracture healing, the most common type of bone repair, [10] relies heavily on endochondral ossification. In this type of healing, endochondral ossification occurs within the fracture gap and external to the periosteum. In contrast, intramembranous ossification takes place directly beneath the periosteum, adjacent to the broken bone’s ...
Marsupialisation results in slow shrinkage of the cyst allowing later enucleation. However, resolution can take up to 20 months and patients are required to clean the open cavity and irrigate it. Peripheral ostectomy after curettage and/or enucleation. Extensive cysts may require a bone graft after bone resection and reconstruction of the area.
Pseudocyst of the auricle, also known as auricular pseudocyst, endochondral pseudocyst, cystic chondromalacia, intracartilaginous auricular seroma cyst, and benign idiopathic cystic chondromalacia, [1] is a cutaneous condition characterized by a fluctuant, tense, noninflammatory swelling on the upper half of the ear, known as the auricle or pinna.
The bones are derived from dermal bone and are part of the dermatocranium. In comparative anatomy , the term is applied to the whole dermatocranium. [ 1 ] In general anatomy, the roofing bones may refer specifically to the bones that form above and alongside the brain and neurocranium (i.e., excluding the marginal upper jaw bones such as the ...
Some unicameral bone cysts may spontaneously resolve without medical intervention. Specific treatments are determined based on the size of the cyst, the strength of the bone, medical history, extent of the disease, activity level, symptoms an individual is experiencing, and tolerance for specific medications, procedures, or therapies.

A unicameral bone cyst, also known as a simple bone cyst, is a cavity filled with a yellow-colored fluid. [ 1 ] [ 3 ] It is considered to be benign since it does not spread beyond the bone. [ 4 ] Unicameral bone cysts can be classified into two categories: active and latent. [ 4 ]
There are two principal types of bones: Dermal bone is directly formed in the dermis (skin), usually growing from initially thin plates. Among others, most bones forming the outer surface of the skull and lower jaws are dermal bones. In contrast, endochondral bone is formed from a cartilaginous precursor, which ossifies (turn into bone). [1 ...
