Hair transplant treatment in GNH hospital
Hair transplantation involves removing small pieces of hair-bearing scalp grafts from a donor site and relocating them to a bald or thinning area.
The truth about hair loss
Baldness is often blamed on poor circulation to the scalp, vitamin deficiencies, dandruff, and even excessive hat-wearing. All of these theories have been disproved. It's also untrue that hair loss can be determined by looking at your maternal grandfather, or that 40-year-old men who haven't lost their hair will never lose it.
Hair loss is primarily caused by a combination of:
- a change in hormones and a family history of baldness
- As a rule, the earlier hair loss begins, the more severe the baldness will become.
Hair loss can also be caused by burns or trauma, in which case hair replacement surgery is considered a reconstructive treatment, and may be covered by health insurance.
Hair transplantation involves removing small pieces of hair-bearing scalp grafts from a donor site and relocating them to a bald or thinning area. Grafts differ by size and shape. Round-shaped punch grafts usually contain about 10-15 hairs. The much smaller mini-graft contains about two to four hairs; and the micro-graft, one to two hairs. Slit grafts, which are inserted into slits created in the scalp, contain about four to10 hairs each; strip grafts are long and thin and contain 30-40 hairs.
Generally, several surgical sessions may be needed to achieve satisfactory fullness-and a healing interval of several months is usually recommended between each session. It may take up to two years before you see the final result with a full transplant series. The amount of coverage you'll need is partly dependent upon the color and texture of your hair. Coarse, gray or light-colored hair affords better coverage than fine, dark-colored hair. The number of large plugs transplanted in the first session varies with each individual, but the average is about 50. For mini-grafts or micro-grafts, the number can be up to 700 per session.
Just before surgery, the "donor area" will be trimmed short so that the grafts can be easily accessed and removed. For punch grafts, your doctor may use a special tube-like instrument made of sharp carbon steel that punches the round graft out of the donor site so it can be replaced in the area to be covered-generally the frontal hairline. For other types of grafts, your doctor will use a scalpel to remove small sections of hair-bearing scalp, which will be divided into tiny sections and transplanted into tiny holes or slits within the scalp. When grafts are taken, your doctor may periodically inject small amounts of saline solution into the scalp to maintain proper skin strength. The donor site holes may be closed with stitches-for punch grafts, a single stitch may close each punch site; for other types of grafts, a small, straight-line scar will result. The stitches are usually concealed with the surrounding hair.
To maintain healthy circulation in the scalp, the grafts are placed about one-eighth of an inch apart. In later sessions, the spaces between the plugs will be filled in with additional grafts. Your doctor will take great care in removing and placement of grafts to ensure that the transplanted hair will grow in a natural direction and that hair growth at the donor site is not adversely affected.
After the grafting session is complete, the scalp will be cleansed and covered with gauze. You may have to wear a pressure bandage for a day or two. Some doctors allow their patients to recover bandage-free.
Plastic surgeons are the leaders in tissue expansion, a procedure commonly used in reconstructive surgery to repair burn wounds and injuries with significant skin loss. Its application in hair replacement surgery has yielded dramatic results-significant coverage in a relatively short amount of time.
In this technique, a balloon-like device called a tissue expander is inserted beneath hair-bearing scalp that lies next to a bald area. The device is gradually inflated with salt water over a period of weeks, causing the skin to expand and grow new skin cells. This causes a bulge beneath the hair-bearing scalp, especially after several weeks.
When the skin beneath the hair has stretched enough-usually about two months after the first operation-another procedure is performed to bring the expanded skin over to cover the adjacent bald area. For more information about tissue expansion, ask your plastic surgeon for the American Society of Plastic Surgeons, Inc. brochure entitled, Tissue Expansion: Creating New Skin from Old.
Flap surgery on the scalp has been performed successfully for more than 20 years. This procedure is capable of quickly covering large areas of baldness and is customized for each individual patient. The size of the flap and its placement are largely dependent upon the patient's goals and needs. One flap can do the work of 350 or more punch grafts.
A section of bald scalp is cut out and a flap of hair-bearing skin is lifted off the surface while still attached at one end. The hair-bearing flap is brought into its new position and sewn into place, while remaining "tethered" to its original blood supply. As you heal, you'll notice that the scar is camouflaged-or at least obscured-by relocated hair, which grows to the very edge of the incision.
In recent years, plastic surgeons have made significant advances in flap techniques, combining flap surgery and scalp reduction for better coverage of the crown; or with tissue expansion, to provide better frontal coverage and a more natural hairline.
This technique is sometimes referred to as advancement flap surgery because sections of hair-bearing scalp are pulled forward or "advanced" to fill in a bald crown.
Scalp reduction is for coverage of bald areas at the top and back of the head. It's not beneficial for coverage of the frontal hairline. After the scalp is injected with a local anesthetic, a segment of bald scalp is removed. The pattern of the section of removed scalp varies widely, depending on the patient's goals. If a large amount of coverage is needed, doctors commonly remove a segment of scalp in an inverted Y-shape. Excisions may also be shaped like a U, a pointed oval, or some other figure.
The skin surrounding the cut-out area is loosened and pulled, so that the sections of hair-bearing scalp can be brought together and closed with stitches. It's likely that you'll feel a strong tugging at this point, and occasional pain.
How you feel after surgery depends on the extent and complexity of the procedure. Any aching, excessive tightness, or throbbing can be controlled with pain medication prescribed by your physician. If bandages are used, they will usually be removed one day later. You may gently wash your hair within two days following surgery. Any stitches will be removed in a week to 10 days. Be sure to discuss the possibility of swelling, bruising, and drainage with your surgeon.
Because strenuous activity increases blood flow to the scalp and may cause your transplants or incisions to bleed, you may be instructed to avoid vigorous exercise and contact sports for at least three weeks. Some doctors also advise that sexual activity be avoided for at least 10 days after surgery.
To make sure that your incisions are healing properly, your doctor will probably want to see you several times during the first month after surgery. It's important that you carefully follow any advice you receive at these follow-up visits.
