Parotid surgery can cause postoperative facial nerve dysfunction, cosmetic impairment, and Frey's syndrome. Thirty-six patients listed for superficial parotidectomy were entered into a prospective randomised trial to find out if the use of a sternocleidomastoid flap could reduce the incidence of these complications. Partial facial nerve paresis was seen at 3 months in five patients in whom flaps were raised compared with six among those who did not have flaps (P=0.025). There was no difference between the two groups at 1 year. The flap was not associated with an improvement in either subjective (P=0.13) or objective (P=0.12) appearance measured on visual analogue scales. Eight patients in whom flaps were raised described symptoms suggestive of Frey's syndrome, compared with nine patients in whom a flap was not raised (P=0.31). Overall 19 of those who had a flap and 11 of those who did not had a positive starch-iodine test (P=0.21).
腮腺手术可导致术后面神经功能障碍、美容缺陷和味觉出汗综合征。36例拟行浅叶腮腺切除术的患者进入一项前瞻性随机试验，以确定使用胸锁乳突肌瓣是否能降低这些并发症的发生率。在3个月时，接受肌瓣移植的5例患者出现部分面神经麻痹，未接受肌瓣移植的患者中有6例出现该情况（P=0.025）。两组在1年时无差异。根据视觉模拟量表测量，肌瓣移植对主观外观（P=0.13）或客观外观（P=0.12）均无改善作用。接受肌瓣移植的8例患者出现了提示味觉出汗综合征（Frey综合征）的症状，未接受肌瓣移植的患者中有9例出现该情况（P=0.31）。总体而言，接受肌瓣移植的患者中有19例淀粉碘试验呈阳性，未接受肌瓣移植的患者中有11例呈阳性（P=0.21）。
