How are the donor site area and number of grafts determined?
To estimate the number of grafts is not an easy job. Here is the approach that we are using in our facility: We first have to calculate the total area of coverage. Based from the total area of coverage then we can decide the size of donor area that should be harvested. From the size of donor area then we can find out number of grafts depends on the size of graft. The sequence is very important. Measure the Area of Coverage Please keep in mind that the scalp is in 3 dimensions so it is very difficult to calculate 100% accuracy, but we only need an approximation. • Discuss with the patient to find out his desired coverage area; and draw the area directly on his scalp with a China Marker (or a black eyebrow pencil). • Apply the transparent sheet (plastic food wrap) over the scalp. • Trace the coverage area on transparent sheet. • Place the transparent sheet over the specially designed graphic paper* to count the number of small squares. (Each small square =1 cm2, big square = 4 cm2). In t
