摘要

Surgical site infection (SSI) is a common complication followed neck dissection and dead space is a common reason of SSI. The present study is aimed to explore whether the sternocleidomastoid muscle (SCM) flap transposition to repair the dead space in level II of neck could decrease the postoperative SSI in patients with oral squamous cell carcinoma (OSCC) underwent supraomohyoid neck dissection (SOND). Ninety-six patients with cT2-3N0 OSCC who underwent extended resection of primary cancer combined SOND and reconstructed with free flap from March 2011 to October 2014 in our department were included. Forty-eight cases underwent SCM transposition to repair the potential dead space in level II of the neck, the other 48 cases did not. The two groups were matched at age, gender, concomitant diseases, and perioperative treatments. All the patients underwent exhaustive hemostasis and careful placement of negative pressure drainage. The wound healing was observed on 7 days postoperatively. The SSI rates of neck between the two groups were compared using Fisher’s exact test. The dead space in level II was observed in all the neck wounds after SOND. The neck wounds healed by primary intention in 46 cases underwent SCM flap transposition, and in 39 cases underwent routine SOND only. Two cases with SCM flap transposition and 9 cases in the group without SCM flap transposition presented SSI in neck. There was significant difference in the SSI rate between the two groups (P = 0.0248). The dead space in level II could be an important cause of SSI in neck followed SOND. Repairing of the dead space in level II using SCM flap transposition reduce the SSI rate of neck followed SOND.
