背景:上唇肌粘膜缺损的重建在手术上具有挑战性。
目的:我们评估了是否可以使用双侧,肌粘膜推进皮瓣(b-BMAFs)。
方法:我们评估了5例早期,涎腺粘液表皮样癌(低度[n=2],中级[n=2],和高级[n=1])接受中央治疗的人,癌消融术后使用b-BMAFs重建上唇肌粘膜。我们治疗了25-59岁的两名男子和三名妇女。肿瘤大小1.8×1.8~2.5×2.2cm。2例和3例患者的临床分期为I期和II期,分别。缺陷尺寸2.8×2.8~3.5×3.2cm。
结果:所有患者均成功重建中央中枢,使用b-BMAFs的上唇肌粘膜缺损,对美学结果感到满意。维持了足够的口轮匝肌和言语功能。没有观察到开口的减少。随访24~36个月,术后36个月发现1例肺转移。
结论:在重建中央时,放置b-BMAF是安全可行的,早期消融术后上唇肌粘膜缺损,涎腺癌。
BACKGROUND: Reconstruction of upper labial myomucosal defects is surgically challenging.
OBJECTIVE: We evaluated whether central defects could be repaired using bilateral, buccinator myomucosal advancement flaps (b-BMAFs).
METHODS: We evaluated five patients with early-stage, minor salivary gland mucoepidermoid carcinomas (low-grade [n = 2], intermediate-grade [n = 2], and high-grade [n = 1]) who underwent central, upper labial myomucosal reconstruction using b-BMAFs after cancer ablation. We treated two men and three women aged 25-59 years. Tumors ranged in size from 1.8 × 1.8 to 2.5 × 2.2 cm. Clinical stages were I and II in two and three patients, respectively. Defect dimensions ranged from 2.8 × 2.8 to 3.5 × 3.2 cm.
RESULTS: All patients underwent successful reconstruction of central, upper labial myomucosal defects using b-BMAFs and were satisfied with the esthetic results. Adequate orbicularis oris and speech function were maintained. No reduction in mouth opening was observed. Patients were followed up for 24-36 months; one pulmonary metastasis was observed at 36 months postoperatively.
CONCLUSIONS: Placement of b-BMAFs is safe and feasible when reconstructing central, upper labial myomucosal defects after ablation of early-stage, minor salivary gland cancer.
