The anatomical limitations of CO2 laser cordectomy in an experimental setting with maximal exposure are presented. The major limitation is the thyroid cartilage. This is reached in the area of anterior commissure tendon by removal of only 2 to 3 mm of soft tissue. Most posteriorly in the larynx, the distance to the thyroid cartilage becomes progressively greater, being 5.3 mm at mid-cord and 9.0 mm at the anterior end of the vocal process of the arytenoid. The inferior limitation is the cricothyroid membrane. Anteriorly this is avoided by not extending laser excision more inferiorly than 5 mm's. Posterolaterally, the limitation is the para-arytenoid musculature. Excisional biopsy or staging with the laser must be within the framework of these limitations.
介绍了在最大暴露的实验环境中二氧化碳激光声带切除术的解剖学局限性。主要局限性是甲状软骨。仅切除2至3毫米的软组织即可到达前联合腱区域的甲状软骨。在喉部最靠后的位置，到甲状软骨的距离逐渐增大，在声带中部为5.3毫米，在杓状软骨声带突前端为9.0毫米。下方的局限性是环甲膜。在前方，通过不将激光切除延伸至比5毫米更低的位置来避免。在后方外侧，局限性是杓旁肌肉组织。激光切除活检或分期必须在这些局限性范围内进行。
