How to – Eyelid H plasty Indications. H plasty can be used for periocular mass removal and is a means of recreating the eyelid margin. It may be used to control tumors or when the other eye is already enucleated. Relevant anatomy. The eyelid margin includes meibomian glands and …

An H-plasty, or two single pedicle advancement flaps, can be used to close larger square or rectangular defects (Figure 5). 1,2,5,7 H-plasties have a wider base:length ratio, improving blood supply when compared to a single pedicle advancement flap. 2

We chose to use the bilateral advancement O-to-H flap (or Hplasty). Design, flap preparation, Burow triangle excision and suture. In the H-plasty pairs of flaps move toward each other on a single vector to hide a central skin defect.

Purpose: To compare the time-zero tibiofemoral contact mechanics among the 4 different suturing repairs: transtibial pullout suture repair, suture anchor repair, side-to-side repair, and H-plasty repair. Methods: Twenty-four human cadaveric knees were included.

2021年7月1日 · Four different repair techniques, transtibial pullout, suture anchor, side-to-side, and H-plasty repair technique, were tested. Tibiofemoral mean and peak contact pressure and contact area in the lateral and medial compartments were measured by Tekscan sensors.

2020年8月24日 · H-plasty reconstructive surgery is commonly used to close defects after tumor excision in the periorbital region. Revascularization of the bipedicle skin flaps is essential for healing. However, it has not previously been possible to study this revascularization in humans due to the lack of noninvasive perfusion monitoring techniques.

2010年4月1日 · If the mass is greater than 25% of the eyelid length then a H-plasty could be used to replace the resected tissue. This usually results in trichiasis, which if severe enough will need to be addressed by cryoepilation.

Smaller lower lid masses (generally SCC) may be removed using H-plasty. Because it is crucial maintain or recreate the eyelid margin, this level of reconstruction is required. n H-plasty procedure pulls up skin from lower on the face to create the margin.

Revascularization of the H-plasty procedure flaps occurs quickly, within a week postoperatively, presumably due to the existing vascular network of the flap pedicle, and was not dependent on significant angiogenesis. This perfusion study confirms the …

For larger wounds, two single pedicle flaps are safer than one large flap. Two advancement flaps are combined to form the H plasty. There are several other well-described flap techniques, including the bipedicle advancement flap and the V-Y advancement flap. In each of these techniques, the coverage depends on stretching the skin over the defect.
