When skin is expanded over time, the pressure gradually causes new tissue to grow. Scalp expansion surgery is a procedure that uses this concept to treat baldness.
Patients undertake scalp expansion if they have a bald patch, basically if the hair will not grow in one area of the scalp. This is common for burn victims, women and men with alopecia or heredity baldness that has not affected the entire scalp. This procedure is suitable for patients who are not entirely bald.
The surgery is a process of small procedures whereby the surgeon implants tissue expanders (balloon like objects), under the sides of the head and the back of the scalp, or by using implanted physical instrumentation. Following the initial surgery to put in the expanders the patient will require follow up appointments to have the expanders filled over the following months, this ensures the expanders continue to expand the scalp. Unfortunately, the expanders may be noticeable and are visible over the months of the procedure. Once the desired effect is achieved the expanders are removed and hair should be generating in the tissue created by the scalp expansion.
The procedure continues for several months and therefore in following the procedure, the results are completely evident throughout the process. The patient should be witnessing changes and progress throughout the procedure.
