Partial laryngectomy for anterior commissure cancer often results in a shortened glottis which produces a high pitched strained voice and an inadequate airway lumen which requires permanent tracheostomy. Vocal fold vibration is impaired both by the shortened length and anterior scarring which profoundly affects the myoelastic properties of the larynx. Many different methods of reconstructing the anterior commissure have been attempted with limited success and many require multiple procedures. A method of anterior commissure reconstruction employing bilateral omohyoid muscle flaps has been performed successfully in four patients. The omohyoid muscles and investing fascia are readily available during partial laryngectomy and can be tailored to reconstitute the anterior commissure. The myofascial flaps epithelialize rapidly and there is little tendency for anterior glottic stenosis. The sphincteric function of the larynx remains intact and the vocal quality surpasses other methods of reconstruction employed by the author.
前联合癌行部分喉切除术常导致声门缩短，从而产生高音调、紧张的嗓音，以及气道管腔不足，这需要永久性气管造口术。声门长度缩短和前部瘢痕均会损害声带振动，这会深刻影响喉部的肌弹性特性。人们尝试了许多不同的前联合重建方法，但成功有限，许多方法需要多次手术。一种采用双侧肩胛舌骨肌瓣进行前联合重建的方法已在4例患者中成功实施。在部分喉切除术中，肩胛舌骨肌和包绕筋膜很容易获得，并且可以进行修整以重建前联合。肌筋膜瓣上皮化迅速，前声门狭窄的倾向很小。喉部的括约肌功能保持完整，嗓音质量超过了作者采用的其他重建方法。
