声门癌T_1及T_2常采用放射治疗,其复发率分别约为10%及30%。这类复发病人的挽救,一般是行全喉切除,以保证有足够的安全切缘和便于术后随诊观察。此外,因在全喉切除术中切除了软骨,从而避免了因足量放射引起软骨炎等并发症。本文作者则认为,相当一部分这类病人,还是有可能采用部分喉手术以保留喉的功能的,关键是要有合适的选择标准。作者提出下列适宜于行部分喉手术的标准:(1)肿瘤侵犯对侧声带的长度不超过0.3cm;(2)除声带突以外,杓状软骨未受肿瘤侵犯;(3)声门下受侵不超
Glottic cancer T_1 and T_2 are often treated with radiation, and their recurrence rates are about 10% and 30%, respectively. The rescue of this type of relapsed patients is generally performed by total laryngectomy to ensure adequate safety margins and to facilitate follow-up observation after surgery. In addition, because cartilage is removed during total laryngectomy, complications such as chondritis caused by sufficient radiation are avoided. The author of this article believes that a considerable portion of these patients may still use partial laryngeal surgery to preserve the function of the larynx. The key is to have appropriate selection criteria. The authors propose the following criteria that are suitable for partial laryngectomy: (1) The length of the contralateral vocal cords of tumor invasion does not exceed 0.3 cm; (2) Beyond the vocal folds, the arytenoid cartilage is not invaded by the tumor; (3) Subglottic invasion Not super
