喉内显微手术已广泛用于切除喉的局限性新生物(如声带小结,息肉,小血管纤维瘤等):手术细腻,功能效果好,复发机会少。但对声带的弥漫肥厚性病变、广基血管性肿瘤、癌前病变、儿童喉乳头状瘤等,用锐利器械彻底切除可致声带粗大瘢痕形成,前联合粘连或严重出血,而保守切除又会有切除不完整之弊,因而有必要在喉内显微手术时并用冷冻治疗。冷冻作用的时间长短有重要临床意义,实验研究证实:冷冻破坏深度决定于冷冻作用时间、
Laryngeal microsurgery has been widely used in the removal of laryngeal limitations of new organisms (such as vocal nodules, polyps, small blood vessel fibroids, etc.): delicate surgery, functional effect, less chance of recurrence. However, the vocal cord diffuse hypertrophic lesions, wide-based vascular tumors, precancerous lesions, laryngeal papilloma and other children, with sharp instruments can be completely removed due to rough scar formation of the vocal cord, the former joint adhesions or severe bleeding, and conservative resection will There are disadvantages of incomplete resection, which is why it is necessary to use cryotherapy during intrathoracic microsurgery. The duration of the role of refrigeration has important clinical significance, experimental studies have confirmed that: the depth of freezing damage depends on the freezing time,
