胸锁乳突肌瓣在腮腺良性肿瘤切除术中的应用

目的：探讨胸锁乳突肌瓣在腮腺良性肿瘤切除术中的应用效果。方法：采用常规＂S＂切口,寻找面神经下颌缘支,逆行解剖面神经至总干,将肿瘤及腮腺浅叶或全叶切除。然后分离胸锁乳突肌瓣旋转至腮腺缺损区,将胸锁乳突肌筋膜与残存的腮腺嚼肌筋膜对位缝合。术后随访观察疗效。结果：术后随访3-24个月,21例均无涎瘘发生,外形良好,颈部功能正常,仅2例出现味觉出汗综合症。结论：胸锁乳突肌瓣修复腮腺区缺损能明显改善腮腺肿瘤术后畸形,有效预防味觉出汗综合症的发生。

Application of Sternocleidomastoid Flap in Operation on Parotid Benign Tumor

Objective： To investigate the clinical values of sternocleidomastoid flaps in operations on parotid benign tumors. Methods： With conventional S-shape incision, the mandible branch of facial nerve was found firstly, then, the main trunk of the nerve was dissected in retrograde steps. The neoplastic mass together with the superficial lobe of parotid gland or the whole gland was resected consequently. The sternocleidomastoid flap was dissected and rotated so as to reconstruct the defect of parotid gland. The sternocleidomatoid fascia and the remaining parotid fascia were stitched together. The postoperative results were followed up. Results： The postoperative follow-ups of all 21cases ranged from 3months to 24months. All cases achieved good aesthetic results and normal cervical functions, without salivary fistula, while Frey＇s syndrome occurred in one case. Conclusion： Application of sternoeleidomatoid flap in reconstruction of defect of parotid gland could remarkably modify the postoperative malformation of parotid ectomy, and effectively prevent Frey＇s syndrome.
