New Tension-free Suture Method in the Forehead Reduction and Scalp Reduction

ABSTRACT

A variety of treatments has been used to correct long forehead and frontal alopecia. These include forehead reduction (scalp reduction), hair graft and flap transfer. Among these procedures, forehead reduction (scalp reduction) is the most simple and effective method. In this procedure, various fixation techniques of scalp flap to cranial bone are used to prevent retraction of the scalp. We used Sherlock (or Piranha) screw to anchor the scalp flap to cranial bone. Between August 1998 and May 2000, this technique had been performed for 37 patients. Average follow-up period was 15 months. For forehead reduction (scalp reduction), the scalp was elevated back to the occipital region through a pretrichial incision, and relaxation incisions of galea was made at a right angle to the vector of advancement. The Sherlock (or Piranha) screw was fixed to the cranial bone. The entire scalp was then repositioned anteriorly, advancing the hairline caudally and shortening the forehead. Retraction of the scalp was prevented by anchoring the galeal fascia to the cranial bone using Sherlock (or Piranha) screws. This technique allows sufficient advancement of the scalp and a tension-free closure. Postoperatively scar widening was less than that of other methods. There were not any infection, hematoma, hair loss nor permanent paresthesia on scalp. In 2 cases, screws were palpable and we removed a screw for 1 case. Advantages of using Sherlock (or Piranha) screw are that the procedure is easy and simple, and sufficient advancement of the scalp, tension-free closure, and less scar widening can be achieved. Disadvantages of this procedure include cost of screw and palpability of screw. In conclusion, by using Sherlock (or Piranha) screw, the procedure was simple and we could get aesthetically good results.
