The temporal muscle has been an essential tool in maxillo-facial reconstruction for more than a century. Despite many technical advances, depression in the temporal fossa after its use is a constant issue. There are several ways to fill this defect. However, their efficiency has not been proven. Currently, biomaterials (e.g. polymethylmethacrylate [PMMA] and polyethylene [PE]) are the alternative most frequently used and studied. This is the first case report of temporal depression filling with a porcine dermal matrix (Permacol™). A 58-year-old woman underwent limited maxillectomy for squamous cell carcinoma of the upper vestibular mucosa, after which a pure temporalis muscle flap was used for immediate reconstruction. A custom-shaped Permacol™ sheet was used with a PMMA spacer to fill the resulting depression at the temporal fossa. The procedure went smoothly without any complications. The surgeon and the patient are satisfied with the cosmetic result. Permacol™ is a safe and effective tool to fill defects after temporalis muscle flap and is an excellent alternative to other biomaterials currently on the market.
颞肌在颌面重建中已经有一个多世纪的历史了。尽管有许多技术进步，但在使用后颞窝凹陷仍然是一个持续存在的问题。有几种方法可以填充这个缺陷。然而，它们的效果尚未得到证实。目前，生物材料（如聚甲基丙烯酸甲酯[PMMA]和聚乙烯[PE]）是最常用和研究最多的替代物。这是首例使用猪真皮基质（Permacol™）填充颞部凹陷的病例报告。一名 58 岁女性因上前庭黏膜鳞状细胞癌接受局限性上颌骨切除术，随后立即使用单纯颞肌皮瓣进行重建。使用定制形状的 Permacol™片和 PMMA 间隔物填充颞窝的凹陷。手术过程顺利，无任何并发症。外科医生和患者对美容效果都很满意。Permacol™是一种安全有效的颞肌皮瓣后填充缺陷的工具，是目前市场上其他生物材料的绝佳替代品。
