累及颞下间隙的颞下颌关节肿瘤的手术进路

Surgical approaches to temporomandibular joint tumor involving infratemporal space

颞下间隙(ITS)位于半侧颌面部中央,内含重要神经血管,既切除此间隙内肿瘤又保存颞下颌关节(TMJ)结构的手术进路是一项挑战。常见ITS进路包括侧方进路、前方进路和下方进路。对于不仅累及ITS还侵犯其他重要结构的肿瘤,需设计联合进路。目前,尚缺乏对切除累及ITS的TMJ肿瘤手术进路的总结。本研究通过回顾近年文献,综述累及ITS的TMJ肿瘤的手术进路。

Infratemporal space （ITS） is in the center of hemi-maxilloface, containing major nerves and vessels. Thus, surgical approaches to tumors inside the space, as well as the protection of temporomandibular joint （TMJ） is difficult. Lateral, anterior and inferior approaches are common surgical approaches to the ITS. But for tumors also involving other major structures, multi-disciplinary cooperation is needed. No summary on different surgical approaches for TMJ tumors extending to the ITS was found. Recent literatures on those approaches were reviewed in this paper.
