Tumescent liposuction (TL) performed according to accepted guidelines has proven to be a safe and effective outpatient procedure. The recent introduction of internal ultrasonic assistance may be a beneficial adjunct to the proven technique of tumescent liposuction at no additional risk to the patient.
To determine whether there are differences in the intra- and postoperative course and the final cosmetic result between TL and internal ultrasonic-assisted tumescent liposuction (I-UATL) with a device using a double-lumen, saline-cooled cannula.
Twenty-eight patients were enrolled in a randomized, prospective, side-to-side comparative study of TL with and without internal ultrasonic assistance. Intraoperative data including patient and physician observations are reported. A blinded evaluation was performed by the nonoperating surgeon of postoperative bruising, swelling, nodularity, skin retraction, decrease in cellulite, and symmetry at regular intervals after the procedure. Patients assessed variables concurrently.
In most cases, the surgeon sensed a greater ease of cannula motion on the I-UATL side, associated with less physician exertion and fatigue. Patients tended to note a more pleasant intraoperative experience on the I-UATL side. We found no significant difference in the degree of postoperative bruising, nodularity, skin retraction, or decreased cellulite as evaluated by the observing physician, although swelling at 1 week was greater on the I-UATL side. The degree of bruising, swelling, soreness, numbness, skin retraction, or decrease in cellulite as reported by the patient did not differ significantly. There were no major complications attributable to either technique.
This study suggests that the addition of internal ultrasonic assistance to the tumescent liposuction procedure may be advantageous regarding less physician effort and increased patient comfort during the procedure. We have not shown a significant difference in the postoperative course or the final cosmetic result when comparing TL with I-UATL.
按照公认指南进行的肿胀吸脂术（TL）已被证明是一种安全有效的门诊手术。最近引入的体内超声辅助技术可能是对已证实的肿胀吸脂技术有益的辅助手段，且不会给患者带来额外风险。
确定使用双腔、盐水冷却套管装置的肿胀吸脂术（TL）与体内超声辅助肿胀吸脂术（I-UATL）在术中和术后过程以及最终美容效果上是否存在差异。
28名患者参与了一项关于有无体内超声辅助的肿胀吸脂术的随机、前瞻性、双侧对比研究。报告了包括患者和医生观察结果在内的术中数据。术后由非手术医生定期对瘀斑、肿胀、结节、皮肤回缩、橘皮组织减少情况及对称性进行盲法评估。患者同时对各项变量进行评估。
在大多数情况下，外科医生感觉I-UATL侧的套管操作更轻松，医生用力和疲劳程度更低。患者倾向于表示在I-UATL侧术中体验更舒适。观察医生评估发现，术后瘀斑、结节、皮肤回缩或橘皮组织减少程度无显著差异，不过I-UATL侧术后1周的肿胀更明显。患者报告的瘀斑、肿胀、酸痛、麻木、皮肤回缩或橘皮组织减少程度也无显著差异。两种技术均未出现重大并发症。
本研究表明，肿胀吸脂术中增加体内超声辅助可能有利于减少医生操作力度并提高患者术中舒适度。比较TL和I-UATL时，我们未发现术后过程或最终美容效果存在显著差异。
