Abstract：
An inferiorly based nasolabial flap (NLF) is a versatile flap for various oral cavity defects. However, it generally necessitates a second stage procedure to release the base at 3 weeks following the initial surgery. Reconstruction for oral cavity defects can be done with the inferiorly based nasolabial flap as a single-stage procedure. In this retrospective clinical audit, we analyzed patients who underwent an inferiorly based NLF reconstruction for oral cavity defect from January 2016 to September 2021. We analyzed the various defects for which this flap was used along with the associated complications and the safety of performing this flap in terms of its flap-related complications and the histopathological features such as margins. Forty-four patients underwent this inferiorly based single-stage NLF. The median age of the patients in the cohort was 56 years, with the majority being men (n = 38, 86.4%). Buccal mucosa and lip were the most common sites of the primary. Twenty-nine patients were per primam and 15 were recurrent cancers. Most had T1 (n = 14, 31.8%) and T2 (n = 19, 43.2%) cancers. The median closest margin was 6 mm and the base was 7 mm. There were no flap losses; however, 6 patients had minor wound breakdown for which secondary suturing was needed. Single-stage NLF is a safe flap that could be considered in select patients for appropriate oral cavity defects.
摘要：
下位鼻唇沟皮瓣（NLF）是一种用于各种口腔缺损的多功能皮瓣。然而,它通常需要一个第二阶段的程序，在3周的初始手术后释放基地。口腔缺损的重建可以使用底部鼻唇沟皮瓣作为单阶段手术来完成。在这次回顾性临床审计中，我们分析了2016年1月至2021年9月期间因口腔缺损而接受了下位NLF重建的患者.我们分析了使用该皮瓣的各种缺陷，以及相关的并发症以及使用该皮瓣的安全性，包括与皮瓣相关的并发症和组织病理学特征，例如边缘。44例患者接受了这种低级单阶段NLF。该队列中患者的中位年龄为56岁，大多数是男性(n=38，86.4%)。颊粘膜和唇是原发性最常见的部位。29例患者为每个primam，15例为复发性癌症。大多数患有T1（n=14，31.8％）和T2（n=19，43.2％）癌症。中位数最接近边缘为6毫米，底部为7毫米。没有襟翼损失；然而，6例患者有轻微的伤口破裂，需要进行二次缝合。单级NLF是一种安全的皮瓣，可以在选择适当的口腔缺损患者中考虑。
