| 설명 | 심장 내부의 인공판막. 심장의 판막이 어떤 원인으로 손상되어 판막의 기능이 유지될 수 없을 때 이 판막을 성형해서 다시 사용하거나(판막성형술) 인공판막으로 치환(판막치환술)해 주어야 한다. 인공판막에는 크게 두 가지가 있는데 하나는 돼지나 소 등의 생체조직으로 만든 조직판막이고 다른 하나는 금속재질로 만든 기계판막이다. 이 두 판막은 서로 장단점이 있는데, 조직판막은 수명이 10년 정도로 짧은 단점이 있는 반면에 판막 주위에 혈액응고가 적어 항응고제 복용이 필요 없고, 손상이 서서히 일어난다. |

| 설명 | 관 혹은 통로에 있는 막과 같은 주름. 내용물의 역류를 막는다. 1.심장판막: 우심방과 우심실사이의 삼첨판, 좌심방과 좌심실사이의 승모판, 우심실과 폐동맥사이의 폐동맥반월판, 좌심실과 대동맥사이의 대동맥반월판이 있다. 2.정맥판막: 정맥에서 발견되는 내막의 작은 첨 혹은 주름. 탄력성이 적어 역류되기 쉬운 정맥혈의 흐름을 역류없이 정상적인 방향으로 지속되도록 해준다. 3.인공판막: 심장판막부족이나 심장판막협착이 있어 더이상 자신의 판막으로는 생존이 불가능할 때 대신 이식하게 되는 인공판막을 말한다. 크게 동물의 조직을 이용한 것과 그렇지 않은 것으로 양분할 수 있다. 동물의 조직을 이용한 것은 주로 돼지나 소의 판막 또는 심외막 등을 이용하며, 그렇지 않은 것은 특수한 금속을 이용하여 만든다. |

| maxillofacial prosthesis | A prosthetic appliance for the replacement of areas of the maxilla, mandible, and face, missing as a result of deformity, disease, injury, or surgery. When the prosthesis replaces portions of the mandible only, it is referred to as mandibular prosthesis. (12 Dec 1998) |

| maxillofacial prosthesis implantation | Surgical insertion of an appliance for the replacement of areas of the maxilla, mandible, and face. When only portions of the mandible are replaced, it is referred to as mandibular prosthesis implantation. (12 Dec 1998) |
| penile prosthesis | Rigid, semi-rigid, or inflatable cylindric hydraulic devices, with either combined or separate reservoir and pumping systems, implanted for the surgical treatment of organic impotence. (12 Dec 1998) |
| periodontal prosthesis | Any restorative and replacement device that is used as a therapeutic aid in the treatment of periodontal disease. It is an adjunct to other forms of periodontal therapy and does not cure periodontal disease by itself. (boucher's clinical dental terminology, 3d ed) (12 Dec 1998) |
| cochlear prosthesis | An electronic device implanted under the skin with electrodes in the middle ear on the promontory or cochlear window or in the inner ear in the cochlea to create sound sensation in total sensory deafness. A microphone behind the ear feeds sound waves into a microprocessor carried on the body, which analyzes the data and sends information back to a radio transmitter that triggers the electrodes in the middle or inner ear to produce the appropriate electrical pulses. This does not enable the patient actually to hear, but rather to distinguish different sounds according to the neural sensation they produce. The first successful cochlear implant was performed in 1978 in Melbourne, Australia. Such devices are among many implanted aids which have been made possible by the advent of microchip technology. Synonym: cochlear prosthesis. (05 Mar 2000) |
| prosthesis | <orthopaedics, surgery> An artificial substitute for a missing body part, such as an arm or leg, eye or tooth, used for functional or cosmetic reasons or both. Origin: Gr. = a putting to (18 Nov 1997) |
| prosthesis colouring | Colouring, shading, or tinting of prosthetic components, devices, and materials. (12 Dec 1998) |
| prosthesis design | The plan and delineation of prostheses in general or a specific prosthesis. (12 Dec 1998) |
| prosthesis failure | Malfunction of implantation shunts, valves, etc., and prosthesis loosening, migration, and breaking. (12 Dec 1998) |
| prosthesis fitting | The fitting and adjusting of artificial parts of the body. (12 Dec 1998) |
| prosthesis implantation | Surgical insertion of a prosthesis. (12 Dec 1998) |
| prosthesis-related infections | Infections resulting from the implantation of prosthetic devices. The infections may be acquired from intraoperative contamination (early) or haematogenously acquired from other sites (late). (12 Dec 1998) |
| provisional prosthesis | An interim dental prosthesis worn for varying periods of time. (05 Mar 2000) |
| hip prosthesis | Replacement for a hip joint. (12 Dec 1998) |
| hybrid prosthesis | A complete denture that is supported by both soft tissue and natural teeth that have been altered so as to permit the denture to fit over them. The altered teeth may have been fitted with short or long copings, locking devices, or connecting bars. Synonym: bar joint denture, hybrid prosthesis, overdenture, telescopic denture. (05 Mar 2000) |
