In Reply We appreciate the interest of Drs Pavlović and Loubser in our article.1 Regarding their first point, that a female cheek may accommodate 80 to 90 injections points rather than 150, we would say that there is substantial variation in cheek size and that the boundaries of the cheek that we specified may be broader than those they equate with the cheek. As the authors appear doubtful, we would like to assure them that we did inject 3 mL of platelet-rich plasma (PRP) into every cheek that was randomized to receive such treatment.
