Contemporary surgery to rejuvenate the aging neck commonly includes some type of platysma modification. Most currently used methods of platysmaplasty involve upper midline plication, muscle resection, or transection. These methods, however, have their shortcomings, often producing necks that display persistent or recurrent paramedian muscle bands, visible submandibular gland bulges, and various contour irregularities. Corset platysmaplasty was developed to avoid these postoperative imperfections. After an adequate subcutaneous and subplatysmal lipectomy has been performed, the two medial edges of the platysma are joined together with a continuous suture that runs down, and up, and down almost the full-height of the neck to create a smooth, flat, multilayered seam, leaving no free muscle edges to return as visible bands. Progressive side-to-side tightening along the midline seam defines the "waistline" of the neck. Additional submandibular suturing is then done to create strong, flat, vertical muscle pleats that correct submandibular gland bulging and refine the jawline and anterolateral neck contours. Corset platysmaplasty is useful for all patients with visible paramedian muscle bands and all patients who would benefit from having a decussated upper neck platysma opened for submuscular defatting, including patients with oblique, palpably firm necks that suggest a vertically short platysma muscle or low-lying hyoid bone. The paper is based on the results with 75 patients having undergone corset platysmaplasty, most having been followed for 1 to 3 years.
当代用于使颈部年轻化的手术通常包括某种类型的颈阔肌修整。目前大多数颈阔肌成形术的方法包括上中线折叠、肌肉切除或横断。然而,这些方法有其缺点,常常导致颈部出现持续或复发性的中线旁肌肉束、可见的下颌下腺隆起以及各种轮廓不规则。束腰式颈阔肌成形术的开发是为了避免这些术后缺陷。在进行充分的皮下和颈阔肌下脂肪切除术之后,颈阔肌的两个内侧边缘用连续缝线缝合在一起,缝线沿着颈部几乎整个高度向下、向上、再向下走行,以形成一条光滑、平坦的多层缝线,不留游离的肌肉边缘以免形成可见的束带。沿着中线缝线进行渐进式的左右收紧确定了颈部的“腰线”。然后进行额外的下颌下缝合,以形成强壮、平坦的垂直肌肉褶,纠正下颌下腺隆起并改善下颌轮廓和颈前外侧轮廓。束腰式颈阔肌成形术适用于所有有可见中线旁肌肉束的患者,以及所有将受益于打开交叉的上颈部颈阔肌进行肌下脂肪去除的患者,包括颈部倾斜、可触及坚硬提示颈阔肌垂直较短或舌骨低位的患者。本文基于75例接受束腰式颈阔肌成形术患者的结果,大多数患者随访了1至3年。
