Extensive full-thickness head and neck burn defects represent some of the greatest challenges because of the exposure of burned calvaria and lack of good local reconstructive options. This study reports the use of a pedicled latissimus dorsi (LD) muscle flap to cover a large full-thickness scalp burn defect measuring 20 × 15 cm, including 15 × 13.7 cm of bone exposure and extending from the posterior neck to the mastoid and vertex of the scalp. The authors discuss the technique to safely maximize the reach, which includes distal dissection to the iliac crest and thoracolumbar fascia, dissection of the pedicle to the axillary vessels, tunnel creation through the pectoralis major muscle, re-attachment of the LD origin to the pectoralis major and teres major, and undermining of the neck skin and subcutaneous tissue to avoid damage of the accessory nerve. This case highlights the reach of a pedicled LD muscle flap for extensive scalp reconstruction for defects all the way to the vertex and beyond. The size and reliability of the LD muscle makes it a valuable alternative for large scalp defects for cases of complex scalp reconstruction in patients deemed not ideal candidates for free flap reconstruction.
大面积全层头颈部烧伤缺损是一些极具挑战性的情况,因为颅骨烧伤暴露且缺乏良好的局部重建选择。本研究报告了使用带蒂背阔肌(LD)肌皮瓣覆盖一个面积为20×15cm的大面积全层头皮烧伤缺损,其中包括15×13.7cm的骨暴露区域,该缺损从后颈部延伸至头皮的乳突和头顶。作者讨论了安全最大化覆盖范围的技术,包括向髂嵴和胸腰筋膜进行远端解剖、向腋血管解剖蒂部、通过胸大肌创建隧道、将背阔肌起点重新附着于胸大肌和大圆肌,以及对颈部皮肤和皮下组织进行潜行分离以避免副神经损伤。该病例突出了带蒂背阔肌肌皮瓣在广泛头皮重建中的覆盖范围,可用于直至头顶及更远部位的缺损。背阔肌的大小和可靠性使其成为在被认为不适合游离皮瓣重建的患者进行复杂头皮重建时,用于大面积头皮缺损的一种有价值的替代方案。
