The oncological safety of a submental (SM) flap is thought to be controversial. The objective of our study was to validate our previous study regarding the oncological safety of SM flaps in oral cavity reconstruction.
An electronic database was searched from 2015 to 2021 for all head-and-neck tumor patients, where reconstruction was performed using a SM flap.
Eighty-eight oral cavity squamous cell carcinoma patients, among whom 71 were males (81.8%), with a mean age of 55.3 years (range: 25-79 years), were retrieved from the database. The sites of involvement were 37 buccal mucosa, 27 lower alveolus, and 24 tongues. The mean follow-up was 33.5 months. The SM flap reconstruction was done for 88 patients; 3 had complete loss of flap, 17 had incomplete loss/partial necrosis, and 68 patients had uneventful recovery of the flap. We had 16 patients with local recurrence. Of these, 4 (4.5%) patients had clear margins and no lymphadenopathy at the level I at the final histopathology report.
This study provides validation of the oncological safety of the SM flap and establishes that nodal positivity at level I alone does not contribute to recurrence at the primary site.
颏下（SM）皮瓣的肿瘤学安全性存在争议。我们研究的目的是验证我们之前关于SM皮瓣在口腔重建中肿瘤学安全性的研究。
检索2015年至2021年的电子数据库，查找所有使用SM皮瓣进行重建的头颈肿瘤患者。
从数据库中检索出88例口腔鳞状细胞癌患者，其中男性71例（81.8%），平均年龄55.3岁（范围：25 - 79岁）。受累部位为颊黏膜37例、下牙槽27例、舌24例。平均随访33.5个月。88例患者进行了SM皮瓣重建；3例皮瓣完全坏死，17例皮瓣部分坏死，68例皮瓣恢复良好。有16例患者出现局部复发。其中，4例（4.5%）患者在最终病理报告中切缘阴性且Ⅰ区无淋巴结转移。
本研究验证了SM皮瓣的肿瘤学安全性，并证实仅Ⅰ区淋巴结阳性不会导致原发部位复发。
