Otoplasty
Otoplasty ( el, οὖς, , "ear" + , , "to shape") denotes the surgical and non-surgical procedures for correcting the deformities and defects of the pinna (external ear), and for reconstructing a defective, or deformed, or absent external ear, consequent to congenital conditions (e.g. microtia, anotia, etc.) and trauma (blunt, penetrating, or blast). The otoplastic surgeon corrects the defect or deformity by creating an external ear that is of natural proportions, contour, and appearance, usually achieved by the reshaping, the moving, and the augmenting of the cartilaginous support framework of the pinna. Moreover, the occurrence of congenital ear deformities occasionally overlaps with other medical conditions (e.g. Treacher Collins syndrome and hemifacial microsomia). History Antiquity Otoplasty (surgery of the ear) was developed in ancient India in the 5th century BC, and described in the medical compendium, the (Sushruta's Compendium, ). The book discussed otoplastic and oth ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Incisionless Fritsch Otoplasty
The Incisionless Fritsch otoplasty is a minimally invasive procedure for pinning protruding ears. History Michael H. Fritsch, MD, Professor, Indianapolis, Indiana, USA, named his method “Incisionless Otoplasty” and published it under this name in 1995, 2004, 2009 and 2013. Surgical procedure The technique is used for protuberant "lop" ears to correct the problem in the least invasive way. From the back of the ear, permanent, non-absorbable sutures (called by Fritsch "retention sutures") are placed invisibly into the cartilage of the external ear pinna with a unique technique, whereby the stitch passes in and out of the same needle hole achieve the desired pathway for the suture to correct the protuberant ear. Kaye and others, made open micro-incisions to get the suture under the skin. When the sutures are tightened, the ear moves towards the head. Patients were operated on using only the percutaneous incisionless technique. Fritsch pointed out that some ears needed not ...

Mustardé Technique
The Mustardé technique is an otoplastic surgery (otoplasty) for pinning protruding ears. The method belongs together with the Stenström and Converse methods to the traditional otoplasties. It is antihelix plastic surgery performed with the suturing technique. History The technique of this surgery was first described by Mustardé in 1960. Further publications by him appeared in 1963 and 1967. Surgical procedure The Mustardé technique involves making a long incision on the back of the ear and removing a strip of skin. The skin is dissected from the cartilage between he edge of the ear (''helix'') and the place where the ear is attached to the head ('' sulcus posterior''), thus exposing the cartilage on the back of the ear. It is therefore assigned to the open ear pinning methods. The antihelix fold is bent more strongly or formed anew with mattress sutures that are anchored in the cartilage. The cartilage is left completely intact, that is, it is not scored, cut or excised as ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Medicine
Medicine is the science and practice of caring for a patient, managing the diagnosis, prognosis, prevention, treatment, palliation of their injury or disease, and promoting their health. Medicine encompasses a variety of health care practices evolved to maintain and restore health by the prevention and treatment of illness. Contemporary medicine applies biomedical sciences, biomedical research, genetics, and medical technology to diagnose, treat, and prevent injury and disease, typically through pharmaceuticals or surgery, but also through therapies as diverse as psychotherapy, external splints and traction, medical devices, biologics, and ionizing radiation, amongst others. Medicine has been practiced since prehistoric times, and for most of this time it was an art (an area of skill and knowledge), frequently having connections to the religious and philosophical beliefs of local culture. For example, a medicine man would apply herbs and say prayers for healing, o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Congenital Abnormality
A birth defect, also known as a congenital disorder, is an abnormal condition that is present at birth regardless of its cause. Birth defects may result in disabilities that may be physical, intellectual, or developmental. The disabilities can range from mild to severe. Birth defects are divided into two main types: structural disorders in which problems are seen with the shape of a body part and functional disorders in which problems exist with how a body part works. Functional disorders include metabolic and degenerative disorders. Some birth defects include both structural and functional disorders. Birth defects may result from genetic or chromosomal disorders, exposure to certain medications or chemicals, or certain infections during pregnancy. Risk factors include folate deficiency, drinking alcohol or smoking during pregnancy, poorly controlled diabetes, and a mother over the age of 35 years old. Many are believed to involve multiple factors. Birth defects may be visib ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Histology
Histology, also known as microscopic anatomy or microanatomy, is the branch of biology which studies the microscopic anatomy of biological tissues. Histology is the microscopic counterpart to gross anatomy, which looks at larger structures visible without a microscope. Although one may divide microscopic anatomy into ''organology'', the study of organs, ''histology'', the study of tissues, and ''cytology'', the study of cells, modern usage places all of these topics under the field of histology. In medicine, histopathology is the branch of histology that includes the microscopic identification and study of diseased tissue. In the field of paleontology, the term paleohistology refers to the histology of fossil organisms. Biological tissues Animal tissue classification There are four basic types of animal tissues: muscle tissue, nervous tissue, connective tissue, and epithelial tissue. All animal tissues are considered to be subtypes of these four principal tissue types ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Harold Gillies
Sir Harold Delf Gillies (17 June 1882 – 10 September 1960) was a New Zealand otolaryngologist and father of modern plastic surgery. Early life Gillies was born in Dunedin, New Zealand, the son of Member of Parliament in Otago, Robert Gillies. He attended Wanganui Collegiate School and studied medicine at Gonville and Caius College, Cambridge, where despite a stiff elbow sustained sliding down the banisters at home as a child, he was an excellent sportsman. He was a golf blue in 1903, 1904 and 1905 and also a rowing blue, competing in the 1904 Boat Race. Career World War I Following the outbreak of World War I he joined the Royal Army Medical Corps. Initially posted to Wimereux, near Boulogne, he acted as medical minder to a French-American dentist, Valadier, who was not allowed to operate unsupervised but was attempting to develop jaw repair work. Gillies, eager after seeing Valadier experimenting with nascent skin graft techniques, then decided to leave for Paris, to meet ...

Temporal Bone
The temporal bones are situated at the sides and base of the skull, and lateral to the temporal lobes of the cerebral cortex. The temporal bones are overlaid by the sides of the head known as the temples, and house the structures of the ears. The lower seven cranial nerves and the major vessels to and from the brain traverse the temporal bone. Structure The temporal bone consists of four parts— the squamous, mastoid, petrous and tympanic parts. The squamous part is the largest and most superiorly positioned relative to the rest of the bone. The zygomatic process is a long, arched process projecting from the lower region of the squamous part and it articulates with the zygomatic bone. Posteroinferior to the squamous is the mastoid part. Fused with the squamous and mastoid parts and between the sphenoid and occipital bones lies the petrous part, which is shaped like a pyramid. The tympanic part is relatively small and lies inferior to the squamous part, anterior to the mast ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Periosteum
The periosteum is a membrane that covers the outer surface of all bones, except at the articular surfaces (i.e. the parts within a joint space) of long bones. Endosteum lines the inner surface of the medullary cavity of all long bones. Structure The periosteum consists of an outer fibrous layer, and an inner cambium layer (or osteogenic layer). The fibrous layer is of dense irregular connective tissue, containing fibroblasts, while the cambium layer is highly cellular containing progenitor cells that develop into osteoblasts. These osteoblasts are responsible for increasing the width of a long bone and the overall size of the other bone types. After a bone fracture, the progenitor cells develop into osteoblasts and chondroblasts, which are essential to the healing process. The outer fibrous layer and the inner cambium layer is differentiated under electron micrography. As opposed to osseous tissue, the periosteum has nociceptors, sensory neurons that make it very sensitive to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mastoid Process
The mastoid part of the temporal bone is the posterior (back) part of the temporal bone, one of the bones of the skull. Its rough surface gives attachment to various muscles (via tendons) and it has openings for blood vessels. From its borders, the mastoid part articulates with two other bones. Etymology The word "mastoid" is derived from the Greek word for "breast", a reference to the shape of this bone. Surfaces Outer surface Its outer surface is rough and gives attachment to the occipitalis and posterior auricular muscles. It is perforated by numerous foramina (holes); for example, the mastoid foramen is situated near the posterior border and transmits a vein to the transverse sinus and a small branch of the occipital artery to the dura mater. The position and size of this foramen are very variable; it is not always present; sometimes it is situated in the occipital bone, or in the suture between the temporal and the occipital. Mastoid process The mastoid process is ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
