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 ...
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. [3]
If the cyst has not expanded beyond the normal anatomical boundaries of the bone, then there will be no palpable lump outside or inside the mouth. The vast majority of cysts expand slowly, and the surrounding bone has time to increase its density around the lesion, which is the body's attempt to isolate the lesion.
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 ]
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 ...
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 ...
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.
They are characterized by interruption of the blood supply of a bone, in particular to the epiphysis, [1] followed by localized bony necrosis, [2] and later, regrowth of the bone. [3] This disorder is defined as a focal disturbance of endochondral ossification and is regarded as having a multifactorial cause, so no one thing accounts for all ...
