There are many surgical techniques available for the management of pterygium. Excision with limbal conjunctival autograft is currently the most popular surgical procedure and has been shown to have low recurrence rate and fewer complications. The fixation of limbal conjunctival autograft is performed with either sutures or fibrin glue. The use of sutures results in longer operating time and intense postoperative irritation and epiphora. We describe a new technique for pterygium excision using a human amniotic membrane-derived dry matrix (Omnigen®; Nottingham, UK: Nu-Vision Biotherapies). The use of Omnigen instead of conjunctival autograft in pterygium surgery is a new promising technique and results in shorter operation time, easier graft fixation, reduction in complications, and less postoperative discomfort. This is a simple technique for pterygium surgery with dry amniotic membrane matrix and without the need for anchoring limbal sutures or an assistant holding the graft whilst it is glued in place.
有多种手术技术可用于翼状胬肉的治疗。带角膜缘结膜自体移植的切除术是目前最常用的手术方法,已被证明具有较低的复发率和较少的并发症。角膜缘结膜自体移植的固定可采用缝线或纤维蛋白胶。使用缝线会导致手术时间延长以及术后强烈的刺激和溢泪。我们描述了一种使用人羊膜衍生的干燥基质(Omnigen®;英国诺丁汉:Nu-Vision生物疗法公司)进行翼状胬肉切除的新技术。在翼状胬肉手术中使用Omnigen替代结膜自体移植是一种新的有前景的技术,可缩短手术时间、使移植片固定更容易、减少并发症并减轻术后不适。这是一种使用干燥羊膜基质进行翼状胬肉手术的简单技术,无需角膜缘缝线固定,也无需助手在移植片粘贴到位时固定。
