Abstract

Squamous cell carcinoma of the lip and oral cavity (OSCC) is a significant global health issue, particularly in low-income countries, with an estimated 390,000 cases detected annually. Although surgery remains the primary treatment option, complex resections are frequently required to attain clear margins. Traditionally, a part of the jaw bone close to the tumour is resected (segmental mandibulectomy) during the surgery. However, marginal mandibulectomy (MM), involving the resection of the mandibular rim while preserving its continuity, offers a less debilitating alternative to segmental mandibulectomy (SM) in selected cases. This review examines marginal mandibulectomy's oncological safety and efficacy and its current role in managing oral cavity cancers, as indicated by the most recent literature. MM is an effective treatment for tumours, which abut the mandible without bone invasion and provides comparable oncological outcomes to SM, with fewer functional and cosmetic deficits. The authors also propose a classification based on the plane of resection and location within the mandible. We believe this classification will be helpful in reporting the MM series done in various centres in a uniform fashion. However, there is a need for precise surgical planning before doing an MM for obtaining the optimal results.

下颌边缘切除术治疗口腔癌的分类和适应症。
唇和口腔鳞状细胞癌(OSCC)是一个重大的全球健康问题,特别是在低收入国家,估计每年发现39万例。虽然手术仍然是主要的治疗选择,但通常需要复杂的切除以获得清晰的边缘。传统上,在手术中切除靠近肿瘤的部分颌骨(节段性下颌骨切除术)。然而,边缘下颌骨切除术(MM),包括切除下颌骨边缘,同时保持其连续性,在某些情况下,提供了一个更少的衰弱替代节段性下颌骨切除术(SM)。根据最新的文献,本文综述了边缘下颌骨切除术的肿瘤安全性和有效性,以及它在口腔癌治疗中的作用。MM是一种有效的治疗肿瘤的方法,它对下颌骨没有骨侵犯,提供与SM相当的肿瘤结果,更少的功能和美容缺陷。作者还提出了一种基于切除平面和下颌骨内位置的分类。我们相信这种分类将有助于以统一的方式报告在各个中心完成的MM系列。然而,为了获得最佳效果,在做MM之前需要精确的手术计划。
