Abstract: Objective To explore the differences between intradermal suturing and interrupted suturing techniques for scalp incision closure in the frontolateral approach surgeries, specifically regarding suturing speed, postoperative wound healing rates, maximum scar width, and average length of hospital stay. This study aims to provide a new strategy for incision closure in the frontolateral approach. Methods A total of 99 patients who underwent the frontolateral approach surgery at Tianjin Huanhu Hospital Neurosurgery Department from February 2020 to February 2024 were selected. Patients were divided into two groups based on the odd or even dates of their surgeries： the interrupted suture group （47 cases） and the intradermal suture group （52 cases）. Data were recorded, including intraoperative suturing time, incision length, postoperative wound healing outcomes, length of hospital stay, and maximum scar width at three months postoperatively. Results The suturing speeds for the interrupted and intradermal suture groups were （1.99±0.62） cm/min and （1.96±0.66） cm/min, respectively. Three months postoperatively, the maximum scar widths were （3.40±1.30） mm for the interrupted suture group and （1.96±0.90） mm for the intradermal suture group. The rates of excellent wound healing were 78.72% for the interrupted suture group and 96.15% for the intradermal suture group. The average length of hospital stay was （11.13±2.87） days for the interrupted suture group and （8.71±3.11） days for the intradermal suture group. Comparisons between the two groups revealed statistically significant differences in rates of excellent wound healing, maximum scar width, and average length of hospital stay （P<0.05）. Conclusion Compared to interrupted suturing, the use of intradermal suturing for closing incisions in the frontolateral approach surgeries can improve postoperative wound healing rates, shorten hospital stay durations, and does not increase surgical time. Additionally, it offers advantages of smaller and more aesthetically pleasing scars.
