Development and utilization of a composite island flap employing omentum: experimental investigation

Plastic and Reconstructive Surgery
O Onur Erol, M Spira

Abstract

In 39 pigs, four varieties of secondary island flaps were created using omentum as a carrier. This study demonstrates that: 1. Skin grafts (split- or full-thickness), when grafted to omentum, can be transformed into an "island flap," and the free transfer of this flap with microvascular anastomosis is feasible. 2. A skin flap, a combined skin flap, or both and subjacent muscle could be vascularized with omentum to obtain an omental island skin flap or an omental island musculocutaneous flap and transferred as already described. 3. Three varieties of secondary island osteocutaneous flaps were created using the omentum. Of these flaps, eight successfully underwent microvascular transfer. Bone vascularity and incontinuity viability were demonstrated by employing a variety of standard diagnostic techniques, including 99mTc-pyrophosphate tetracycline labeling, microangiography, and histologic sectioning. In addition to the many recognized advantages of a free living bone graft in reconstructive surgery, other benefits of this new kind of island composite flap include its unlimited size, minimal donor deformity, and ease of transfer. We have demonstrated that omentum can be used to vascularize skin, a skin flap, and either tibial, co...Continue Reading

COVID-19

Coronaviruses encompass a large family of viruses that cause the common cold as well as more serious diseases, such as the ongoing outbreak of coronavirus disease 2019 (COVID-19; formally known as 2019-nCoV). Coronaviruses can spread from animals to humans; symptoms include fever, cough, shortness of breath, and breathing difficulties; in more severe cases, infection can lead to death. This feed covers recent research on COVID-19.

Evolution of Pluripotency

Pluripotency refers to the ability of a cell to develop into three primary germ cell layers of the embryo. This feed focuses on the mechanisms that underlie the evolution of pluripotency. Here is the latest research.

Chronic fatigue syndrome is a disease characterized by unexplained disabling fatigue; the pathology of which is incompletely understood. Discover the latest research on chronic fatigue syndrome here.

Torsion Dystonia

Torsion dystonia is a movement disorder characterized by loss of control of voluntary movements appearing as sustained muscle contractions and/or abnormal postures. Here is the latest research.

Archaeal RNA Polymerase

Archaeal RNA polymerases are most similar to eukaryotic RNA polymerase II but require the support of only two archaeal general transcription factors, TBP (TATA-box binding protein) and TFB (archaeal homologue of the eukaryotic general transcription factor TFIIB) to initiate basal transcription. Here is the latest research on archaeal RNA polymerases.
