How it works
Everything begins with a consultation. Your doctors will examine the area of scalp loss, measure its size, assess the healthy tissue around it, and check whether the skull beneath is exposed or damaged. You will be asked about the cause, how long the wound has been there, your medical history, and any medicines you take. This is also the time to share what you hope for and to ask your questions.
Depending on how much tissue is involved, the operation is usually done under general anaesthesia. For smaller areas it is sometimes done with local anaesthetic and sedation. Your doctor will choose the method of coverage that suits your wound.
Common techniques include drawing the two skin edges together and stitching them if the loss is small; a skin graft, where a thin layer of skin is taken from another part of your body and laid over the wound; or a local scalp flap, where healthy scalp next to the wound is rotated to cover the gap. For larger defects or wide areas of exposed bone, a free flap may be needed — tissue with its own blood vessels is moved from elsewhere, and the vessels are reconnected under a microscope.
In many cases, your doctor may divide the work into stages: for example, placing a temporary covering first, or using a tissue expander to grow more healthy scalp before reconstructing the area. Your doctor will explain the plan expected for your particular case before going ahead.
