To determine the effectiveness and safety of the Silastic midfacial malar implant and to review indications, patient selection, technique, and complications of malar augmentation.
Five-year retrospective review of clinical cases with at least 2-year follow-up.
A cohort of 60 consecutive private patients with complaints of malar hypoplasia or facial asymmetry.
A plastic surgery clinic.
Silastic midfacial malar implants were fitted in each patient. Most underwent implantation via the canine fossa approach and in conjunction with another facial plastic procedure.
Subjective patient satisfaction, photographic grading using a visual analog scale, and complications.
Of the 60 patients, 51 (85.0%) reported an excellent result after at least a 2-year follow-up. Ten patients (16.7%) had some form of undesirable sequelae; however, only 4 (3.4%) of 118 implants had to be revised. Photographically, all 60 patients graded postoperative improvement.
Findings support the contention that the Silastic midfacial malar implant is a safe and effective alloplastic alternative to treat malar hypoplasia and facial asymmetry. The complication and revision rates are acceptable. Relative technical ease of insertion makes malar augmentation an excellent adjunct for rhytidectomy and rhinoplasty.
确定硅橡胶中面部颧骨植入物的有效性和安全性，并回顾颧骨增高术的适应症、患者选择、技术及并发症。
对临床病例进行五年回顾性研究，随访至少两年。
连续60例因颧骨发育不全或面部不对称前来就诊的私立患者。
一家整形手术诊所。
为每位患者植入硅橡胶中面部颧骨植入物。大多数患者通过犬齿窝入路植入，并同时进行另一项面部整形手术。
患者主观满意度、使用视觉模拟量表进行照片分级以及并发症情况。
60例患者中，51例（85.0%）在至少两年的随访后报告效果极佳。10例患者（16.7%）出现某种形式的不良后遗症；然而，118枚植入物中只有4枚（3.4%）需要翻修。从照片上看，所有60例患者术后均有改善。
研究结果支持以下观点，即硅橡胶中面部颧骨植入物是治疗颧骨发育不全和面部不对称的一种安全有效的异体替代物。并发症和翻修率均可接受。相对简便的植入技术使颧骨增高术成为除皱术和鼻整形术的理想辅助手段。
