作者们从1966年起,将行喉切除的700余例喉标本作切片研究,以期对喉癌的生长和播散有较好了解。作者们认为声带固定对标准的垂直半喉切除是禁忌症。对广泛性肿瘤的治疗,可做喉广泛次全切除。手术成功有赖于对扩散型肿瘤和手术时切除缘冰冻切片安全范围的了解。涉及前联合区的广泛性肿瘤常扩散到声门下,侵犯甲状软骨板下缘,通过环甲膜扩散到喉外,乃至肿瘤直接处于颈前皮肤下。为了避免遗留皮下肿瘤,可从该区作一椭圆形皮肤切除,作为喉切除的一
In 1966, the authors performed a slice study of more than 700 throat specimens taken from a laryngectomy in order to better understand the growth and spread of laryngeal cancer. The authors believe that vocal cord fixation is a contraindication to standard vertical hemi-halectomy. For the treatment of extensive tumors, extensive subtotal laryngectomy can be performed. The success of the surgery depends on understanding the spread of tumors and the safety margin of the resection margin frozen section during surgery. Extensive tumors involving the former joint area often spread to the subglottis, invade the lower edge of the thyroid cartilage plate, spread through the thyrocral membrane outside the larynx, and even the tumor directly under the skin of the neck. In order to avoid leaving subcutaneous tumors, an oval skin resection can be made from this area as a laryngectomy.
