Abstract

Background: Transoral laser microsurgery, the standard surgical approach for early-stage laryngeal cancer, necessitates an unobstructed line of sight to the operating field. However, achieving adequate laryngeal exposure can be challenging, potentially compromising treatment outcomes.

Methods: We developed a 3D-printed curved laryngoscope (sMAC), designed to match the upper airway anatomy. In a user study (n = 15) with a human body donor we compared the sMAC system to conventional microlaryngoscopy regarding laryngeal exposure and accessibility in a difficult exposure scenario.

Results: All 15 participants achieved complete glottic exposure and successfully manipulated laryngeal landmarks using the sMAC system. Only four participants achieved partial exposure using microlaryngoscopy. Positioning of the sMAC system was significantly faster (p = 0.023). A vocal cord resection was conducted successfully (n = 2) using the sMAC system.

Conclusion: The sMAC system effectively addresses challenges associated with transoral laryngeal surgery. Ongoing development aims to overcome current limitations of the system and prepare first clinical trials.

打破常规：供体研究中的喉部手术新方法。

背景：经口激光显微手术是治疗早期喉癌的标准手术方法，它要求手术区域的视线畅通无阻。然而，实现喉部的充分暴露具有挑战性，可能会影响治疗效果：我们开发了一种 3D 打印的弧形喉镜（sMAC），其设计符合上气道解剖结构。在一项使用人体供体的用户研究（n = 15）中，我们比较了 sMAC 系统与传统显微喉镜在喉部暴露和暴露困难情况下的可及性：结果：所有 15 名参与者都使用 sMAC 系统实现了完全的声门暴露，并成功操作了喉部地标。只有四名参与者使用显微喉镜实现了部分暴露。sMAC 系统的定位速度明显更快（p = 0.023）。使用 sMAC 系统成功进行了声带切除术（n = 2）：结论：sMAC 系统能有效解决经口喉手术的相关难题。结论：sMAC 系统有效地解决了经口喉手术的相关难题，目前正在进行的开发工作旨在克服该系统目前存在的局限性，并为首次临床试验做好准备。
