To evaluate the effect of Nickle-Titanium alloys annular stent to prevent and treatment tracheostomal stenosis after total laryngectomy.
The stent was used following total laryngectomy and after total laryngectomy.
Long stent was implanted in 2 cases following total laryngectomy and in 1 cases after total laryngectomy, Which resulted in widening stenosis and relieving obstruction of airway. The tracheostomal diameter is 2 cm afterwards, but the patients have crusts, granuloma and stretch feeling in tracheostoma. Tracheostomaplasty was performed using short stent in 18 cases during laryngectomy. All the cases have no tracheostomal stenosis following over 6 months. The tracheostoma is smooth, enough larger and stable.
Nickle-Titanium alloys annular short stent is fixed outside the wall of trachea, its complication is less. It may prevent from tracheostomal stenosis. Nickle-Titanium alloys annular long stent is a better method to resolve dyspnea.
评估镍钛合金环形支架在全喉切除术后预防和治疗气管造口狭窄的效果。
在全喉切除术中及全喉切除术后使用该支架。
全喉切除术后有2例植入长支架，全喉切除术后有1例植入长支架，导致狭窄扩大并缓解气道阻塞。之后气管造口直径为2厘米，但患者气管造口处有结痂、肉芽肿和牵拉感。在喉切除术中使用短支架对18例患者进行气管造口成形术。所有病例随访超过6个月均无气管造口狭窄。气管造口光滑，足够大且稳定。
镍钛合金环形短支架固定于气管壁外，并发症较少。它可预防气管造口狭窄。镍钛合金环形长支架是解决呼吸困难的较好方法。
