| Popis: | Introduction. Definition " upper respiratory tract stenosis " (URTS) includes a large number of nosologies. The most common are cicatricial stenoses, in particular, post-intubation ones as well as bilateral paralysis of the larynx. An important issue for nowadays is choosing the curative modality for such patients.Purpose. To compare outcomes after treating children with URTS.Material and methods. The authors have assessed results of treatment of 110 patients who had reconstructive surgery in 2010-2019. Patients were divided into two groups depending on the nosology: stenosis of the upper respiratory tract (n = 71) and bilateral paralysis of the larynx (n-39). In each group, four types of surgeries were performed: costal cartilage plasty, plasty with T-tube (TT), a modified version of plasty with TT, plasty with a stent. The choice of treatment technique was determined mostly by the tendency to make this or that type of surgery in authors' departments, as well as by the nosology, severity of the disease and patient's age. Decannulation terms, surgical time, early and late postoperative complications as well as relapse-free period were assessed.Results. 66% patients were decannulated in Group 1; in Group 2 - 69%. Group 1 a statistically reliable comparison was possible between the following techniques: costal cartilage plasty and laryngeal stent plasty (p > 0.005) as well as plasty with TT implantation and the proposed modified technique (p > 0.005). While using Mann-Whitney test and Log Rank, the authors found out that in Group 1 there were no significant difference in surgical time, relapse-free period and stenosis degree (p > 0.005). However, decannulation terms after plastic surgery of the larynx with costal cartilage implantation are longer than after plastic surgery with stent implantation (p < 0.005). In Group 2, the authors compared three abovementioned curative modalities, excluding laryngeal plasty with TT implantation. Thus, surgical time for costal cartilage plasty is longer, if to compare to other two techniques (p < 0.005). There is also no significant difference in decannulation terms and relapse-free periods between all three techniques (p > 0.005).Conclusion. The results obtained have demonstrated the effectiveness of long-term stenting with TT placement in children, mainly with cicatricial stenoses, and in older children. The trial also revealed that laryngoplasty with costal cartilage in children with bilateral laryngeal paralysis is an effectiveness choice too. |
