目的:总结解剖面神经颧支在腮腺良性肿瘤切除术中的临床应用。方法:采用经典的面部除皱手术切口,在腮腺嚼肌筋膜下翻瓣,先在耳屏前颧弓下解剖显露面神经的颧支,然后沿该支显露面神经的颞面干及面神经总干,再根据肿瘤的位置沿总干选择性地解剖面神经颈面干及各分支,行肿瘤及腮腺部分切除术。最后采用蒂在上方的胸锁乳突肌肌瓣转移填塞腮腺切除后的凹陷区,避免了常规术式术后耳前区的凹陷畸形。结果:采用该术式对19例患者行腮腺良性肿瘤切除术,所有手术均顺利完成,术后随访3～4年,患者面部疤痕不明显,外形恢复良好,面神经损伤均完全恢复。结论:本术式更易于显露和保护面神经,改善术后面部畸形。
Objective: To summarize the clinical application of zygomatic branch of the anatomical nerve in parotid benign tumor resection. Methods: A classic facial incision was performed to flap under the fascia of the parotid cheek muscle. First, the zygomatic branch of the facial nerve was dissected under the zygomatic arch before the tragus. Then, the facial and facial nerve trunk , And then according to the location of the tumor along the total dry selectively dissected facial nerve neck and the branches, the tumor and parotid partial resection. Finally, the pedicle of the sternocleidomastoid muscle flap pedicled above is used to transfer the stuffed area after the parotid gland resection to avoid the deformity of the denture area in the conventional operation. RESULTS: Twenty-nine patients underwent parotidectomy with this procedure. All operations were successfully completed. The patients were followed up for 3 to 4 years. The facial scar was not obvious and the appearance recovered well. Facial nerve injury was completely recovered. Conclusion: This procedure is easier to reveal and protect the facial nerve, to improve postoperative facial deformity.
