Reconstruction of small to medium lower lip defects commonly includes mucosal advancement and wedge excision with primary closure, resulting in aesthetic complications such as lip flattening, shortening, and loss of the vermilion roll. The myomucosal lip island flap offers an alternative that preserves lower lip appearance and function. To describe the lateral myomucosal lip island flap and its indications for the reconstruction of small to medium lower lip defects. A retrospective chart analysis of patients from 2014 to 2019 was done. Participants include all consecutive patients of the senior author who had the myomucosal lip island flap employed in the lower lip from 2014 when the senior author began employing this technique, including 20 patients. Patient demographics, surgical indications, surgical defect bridging distances, flap advancing distances, functional complications, and aesthetic outcomes were reported. IRB approval was obtained from St. Joseph Health Center for Clinical Research and surgeries were performed at a private tertiary referral center-Skin Cancer and Reconstructive Surgery Center-by the senior author in a multispecialty practice. Location and flaps utilized to reconstruct the defect were reported. Lateral advancing distance and overall bridging distance were measured. Functional complications, if any, were reported. Appearance rating after the first stage was assessed. This case series included 20 patients with lower lip defects reconstructed with myomucosal lip island flaps. The average bridging distance (width of defect) was 1.7 cm (minimum 1.0 cm, maximum 2.8 cm). Of 18 patients with available postoperative photographs, 4 cases (22%) had mild vermilion inferior retraction, 1 case (6%) had mild contour irregularity, and 1 case (6%) had visible white scar in the red lip. The myomucosal lip island flap is a reliable technique for reconstruction of small to medium lower lip defects, preserving lip fullness and the vermilion roll.
小到中型下唇缺损的重建通常包括黏膜推进和楔形切除及一期缝合，导致唇部扁平、缩短和唇红卷丧失等美学并发症。肌黏膜唇岛瓣提供了一种替代方法，可保持下唇的外观和功能。描述小到中型下唇缺损的外侧肌黏膜唇岛瓣及其适应证。对 2014 年至 2019 年期间的患者进行了回顾性图表分析。参与者包括高级作者连续治疗的所有患者，他们从 2014 年高级作者开始使用该技术时就使用了肌黏膜唇岛瓣，共 20 例。报告了患者人口统计学、手术适应证、手术缺损桥接距离、皮瓣推进距离、功能并发症和美学结果。圣约瑟夫健康中心临床研究伦理委员会批准，手术在一家私人三级转诊中心——皮肤癌和重建外科中心——由高级作者在一个多专科诊所进行。报告了重建缺损时使用的位置和皮瓣。测量了外侧推进距离和整体桥接距离。报告了任何功能并发症。评估了第一阶段后的外观评分。该病例系列包括 20 例使用肌黏膜唇岛瓣重建下唇缺损的患者。平均桥接距离（缺损宽度）为 1.7cm（最小 1.0cm，最大 2.8cm）。18 例有术后照片的患者中，4 例（22%）有轻度唇红下部退缩，1 例（6%）有轻度轮廓不规则，1 例（6%）红唇可见白色瘢痕。肌黏膜唇岛瓣是小到中型下唇缺损重建的可靠技术，可保持唇部丰满度和唇红卷。
