What Is a Dilator?

Dilator is an advanced treatment method unique to plastic surgery. Its principle is to implant the skin soft tissue expander under the normal skin and soft tissue near the lesion, and then intermittently inject liquid into the expansion capsule to increase the capacity of the expander, which will cause the skin and soft tissue to surface. pressure.

The local effect of the expansion mechanism through the expansion mechanism

Tissue expander is an advanced treatment method of "skin" and "skin".

After the removal of huge scars or body masses, the repair of secondary skin defects was once a very challenging problem. It is necessary to find enough autogenous skin to cover the wound surface, and for exposed parts such as the head and face, it is required that the skin color and texture covering the wound surface should be as same as the original tissue. The appearance of the dilator solves this problem well.

Round tissue expander

Dilator is an advanced treatment method peculiar to plastic surgery. Its principle is to implant a soft skin tissue expander under normal skin and soft tissue near the lesion, and then intermittently inject liquid into the expansion capsule to increase the capacity of the expander and cause it to produce soft skin Pressure, through the local action of the expansion mechanism, causes the division and proliferation of tissues and epidermal cells and the enlargement of intercellular spaces, thereby increasing the skin area. After removing the expansion capsule, the newly added skin and soft tissue can be used for tissue repair and organ reconstruction.

The skin soft tissue expander was first applied to the treatment of scarred baldness. After removing the hairless growing scar area, the normal hairy skin expanded around the scar was used to repair the resected secondary tissue defect. Through the hair around the scar, Redistribution to achieve baldness treatment. In addition to the treatment of hair loss, the full layer of scalp loss caused by trauma or removal of tumors and nevus can also be repaired with expanded skin and soft tissues. The biggest advantage is that the repaired scalp has hair and scars. It is almost impossible to find under the cover of hair.

Similar to the method of repairing hairy areas of the head, large scars on the face and neck, pigmented nevus, hemangiomas, traumatic tattoos, and tissue defects caused by tumor resection can also be treated with dilators. The skin is exactly the same as the surrounding skin, and the cosmetic effect is more ideal. In addition, in the reconstruction of facial organs (such as whole ear and whole nose reconstruction), the dilator also played an irreplaceable role.
