摘要

Background: Disruption of medial canthus can result in telecanthus. The goal of surgical management is to correct the anatomical location of medial canthus and to place strong and stable fixation, which can be challenging. Multiple techniques have been described, such as transnasal wiring, ipsilateral fixation by screws, bottoms, plates or titanium anchor system. Objective: Here we describe a case using soft anchoring device in medial canthopexy and conduct a literature review on this technique. Materials and Methods: A 39-old-old male patient underwent a severe traffic accident and presented with right orbital floor blow-out fracture, nasal bone fracture, nasolacrimal duct rupture and left telecanthus. After open reduction for nasal bone, we performed 2-staged rhinoplasty, not only for correcting his saddle nose also enhancing bone stock of medial orbital wall. One year later, we performed medial canthopexy with a soft anchor suture (1.0 mm Juggerknot soft anchor-Mini; Biomet, Warsaw, IN, USA) and epicanthoplasty. Result: The medial canthal angle was then moved 1cm medially and the intercanthal distance remained stable and satisfied after 1-year-fallowed up. Conclusion: Using soft anchor in medial canthopexy is easy, safe, and providing stable and satisfied fixation for medial canthus.

背景：內眥韌帶（medial canthus）斷裂將會導致眼距過寬（telecanthus），手術矯正的要點在於恢復韌帶原始解剖結構、提供力量強及穩定的固定。多種手術方式曾被提及，包含經鼻鐵絲固定（transnasal wiring）、同側經由螺絲、鈕釦、骨板、或是金屬錨釘系統固定。目的及目標：本論文將描述經由軟錨釘系統做內眥韌帶固定術，並針對此技術進行文獻回顧。材料及方法：一位39歲男性經歷了嚴重交通事故，呈現右眼底骨折、鼻骨骨折、鼻淚管破裂及左眼距過寬。在接受了鼻骨固定後，我們又為他進行了兩階段的鼻整形術後，除了矯正他的馬鞍鼻外，更重要的是增強他內眼眶的骨含量。一年後，我們為他進行了經由軟錨釘系統做內眥韌帶固定術及眼頭成形術。結果：病人的左內眥向內移了一公分，在一年的術後追蹤中眼距維持良好及穩定。結論：經由軟錨釘系統做內眥韌帶固定術是一簡單、安全、且能提供力量強及穩定的固定方式。
