The paraglottic space is an essential anatomic compartment of the larynx. It is central to the spread of laryngeal cancer and to the choice of conservative laryngeal surgery and many phonosurgical procedures. Since its description, 60 years ago, the surgical anatomy of the paraglottic space was sparsely revisited. Amid the era of endoscopic and transoral microscopic functional surgery of the larynx, we provide here a long-awaited description of the inside-out anatomy of the paraglottic space.
Using an endoscope equipped with a 3D camera, we dissected 10 hemilarynges from 5 fresh frozen cadavers from the inside out. Before dissection, we labeled the vessels through injecting them with colored latex. We explored the paraglottic space emphasizing its shape, boundaries, and contents. We documented our findings through endoscopic photography and video recordings.
The paraglottic space is a spacious tetrahedral space located parallel not only to the glottic, but also to the subglottic and the supraglottic compartments of the laryngeal lumen. It has musculo-cartilaginous, musculo-fibrous, and mucosal boundaries. It is separated from the pyriform sinus only by mucosa. A cushion of fat surrounds its vascular and to a lesser extent its neural contents. Harbored intrinsic laryngeal muscles are endoscopically identifiable within the space, namely the thyroarytenoid, the lateral, and posterior cricoarytenoid muscles.
The endoscopic description of the paraglottic space partly fills the knowledge gap on the laryngeal anatomy from the inside out. It opens the door for novel diagnostic methods and for ultraconservative functional laryngeal interventions under endoscopic control.

声门旁间隙是喉的一个重要解剖区域。它对于喉癌的扩散以及保守性喉手术和许多嗓音外科手术的选择至关重要。自60年前其被描述以来，声门旁间隙的外科解剖学很少被重新审视。在喉内镜和经口显微功能手术时代，我们在此提供了期待已久的声门旁间隙由内向外的解剖学描述。
我们使用配备3D摄像头的内镜，从5具新鲜冷冻尸体中取出10个半喉，由内向外进行解剖。在解剖前，我们通过向血管内注射彩色乳胶对其进行标记。我们探查声门旁间隙，重点关注其形状、边界和内容物。我们通过内镜摄影和录像记录我们的发现。
声门旁间隙是一个宽敞的四面体间隙，不仅与声门平行，还与喉腔的声门下和声门上区域平行。它有肌肉 - 软骨、肌肉 - 纤维和黏膜边界。它仅通过黏膜与梨状窝分隔。一层脂肪围绕着其血管，在较小程度上围绕着其神经内容物。在该间隙内可在内镜下识别出喉内固有肌，即甲杓肌、环杓侧肌和环杓后肌。
声门旁间隙的内镜描述部分填补了由内向外的喉解剖学知识空白。它为新的诊断方法以及在内镜控制下的超保守功能性喉干预打开了大门。
