BACKGROUND: To know the difference between single and double-layer wound closure. METHODS: The study was conducted in ten patients undergoing first session of hair restoration surgery by ‘strip method’ under local anaesthesia. Informed consent was obtained from all the patients. The length and width of the strip were marked pre-operatively. Three points were marked, one in the midline ‘O’ and one on either side, ‘A’ & ‘B’ at 8 cm from ‘O’. After removing the strip, five deep, interrupted, absorbable sutures were applied on left half but not on the right half. Lower edge trichophytic closure was performed with no undermining of the skin edges. A single continuous non-absorbable sutures was used to close the skin. The stitches were removed on the 10th postoperative day. The patients were assessed at 9 months interval postoperatively. RESULTS: The mean age of the patients was 33.8 years. The average width of the strip removed was 15.1 mm. The average width of the scar on single-layer closure was 1.57 mm and 1.58 mm on the double-layer closure. The mobility of the scar was 7.9 mm on single-layer closure and 6.2 mm on double-layer closure. There was no statistical significance in the scar size and mobility of single-layer vs double-layer closure. The time of surgery was more in double-layer closure and the extra cost of the suture material. CONCLUSIONS: There was no difference in scar quality. The extra time and money was saved in single-layer closure. The mobility of the scar was also found to be better in single-layer closure.
