Importance Bilateral vocal cord paralysis is a challenging problem to manage in adults, and a known complication of thyroid surgery which is more common in resource-limited settings. Posterior graft laryngotracheal reconstruction is a management option that has not been studied in this population or setting. Objective To report the surgical outcomes of posterior graft laryngotracheal reconstruction for bilateral vocal cord paralysis in a resource-limited setting, and to evaluate the efficacy of a hybrid system for teaching this technique in Kenya. Design Retrospective cohort study. Setting Tertiary public referral hospital, Eldoret, Kenya Participants Adults >18 years with tracheostomy dependence secondary to bilateral vocal cord paralysis after thyroid surgery or other iatrogenesis. The hybrid training program included Kenyan surgeons and surgical trainees. Intervention or Exposures Posterior graft laryngotracheal reconstruction and hybrid training system included didactic lectures, simulation-based training, case discussion and planning, and live cases. Main Outcomes Measures One-year airway outcomes measured by achievement of tracheostomy decannulation, and self-reported surgeon knowledge and skill acquisition. Results Ten patients met criteria and were included in the analysis, with mean age 42 years (range 30-62 years) and had been tracheostomy dependent for an average of 6 years (range 1-12 years). Seven (70%) had open reconstruction, and 3 (30%) had endoscopic reconstruction. All were decannulated and remained tracheostomy-free at 1 year. Three surgeons and 7 trainees participated in the hybrid teaching methods. All reported increased comfort in laryngotracheal reconstruction, with all 3 surgeons reporting comfort performing the surgeries independently. Conclusion Posterior graft laryngotracheal reconstruction shows promise as a potential method of treating bilateral vocal cord paralysis and achieving decannulation in a resource-limited setting. Relevance The methods reported in this study lend themselves to replication and expansion to other similar settings. The authors plan to replicate this work in other centers in East Africa.

Objectives/HypothesisCreate a competency‐based assessment tool for pediatric tracheotomy.Study DesignBlinded, modified, Delphi consensus process.MethodsUsing the REDCap database, a list of 31 potential items was circulated to 65 expert surgeons who perform pediatric tracheotomy. In the first round, items were rated as “keep” or “remove,” and comments were incorporated. In the second round, experts were asked to rate the importance of each item on a seven‐point Likert scale. Consensus criteria were determined a priori with a goal of 7 to 25 final items.ResultsThe first round achieved a response rate of 39/65 (60.0%), and returned questionnaires were 99.5% complete. All items were rated as “keep,” and 137 comments were incorporated. In the second round, 30 task‐specific and seven previously validated global rating items were distributed, and the response rate was 44/65 (67.7%), with returned questionnaires being 99.3% complete. Of the Task‐Specific Items, 13 reached consensus, 10 were near consensus, and 7 did not achieve consensus. For the 7 previously validated global rating items, 5 reached consensus and two were near consensus.ConclusionsIt is feasible to reach consensus on the important steps involved in pediatric tracheotomy using a modified Delphi consensus process. These items can now be considered to create a competency‐based assessment tool for pediatric tracheotomy. Such a tool will hopefully allow trainees to focus on the important aspects of this procedure and help teaching programs standardize how they evaluate trainees during this procedure.Level of Evidence5 Laryngoscope, 130:2700–2707, 2020

ObjectivesDevelop multidisciplinary and international consensus on patient, disease, procedural, and perioperative factors, as well as key outcome measures and complications, to be reported for pediatric airway reconstruction studies.MethodsStandard Delphi methods were applied. Participants proposed items in three categories: 1) patient/disease characteristics, 2) procedural/intraoperative/perioperative factors, and 3) outcome measures and complications. Both general and anatomic site‐specific measures were elicited. Participants also suggested specific operations to be encompassed by this project. We then used iterative ranking and review to develop consensus lists via a priori Delphi consensus criteria.ResultsThirty‐three pediatric airway experts from eight countries in North and South America, Europe, and Australia participated, representing otolaryngology (including International Pediatric Otolaryngology Group members), pulmonology, general surgery, and cardiothoracic surgery. Consensus led to inclusion of 19 operations comprising open expansion, resection, and slide procedures of the larynx, trachea, and bronchi as well as three endoscopic procedures. Consensus was achieved on multiple patient/comorbidity (10), disease/stenosis (7), perioperative‐/intraoperative‐/procedure‐related (16) factors. Consensus was reached on multiple outcome and complication measures, both general and site‐specific (8 general, 13 supraglottic, 15 glottic, 17 subglottic, 8 cervical tracheal, 12 thoracic tracheal). The group was able to clarify how each outcome should be measured, with specific instruments defined where applicable.ConclusionThis consensus statement provides a framework to communicate results consistently and reproducibly, facilitating meta‐analyses, quality improvement, transfer of information, and surgeon self‐assessment. It also clarifies expert opinion on which patient, disease, procedural, and outcome measures may be important to consider in any pediatric airway reconstruction patient.Level of Evidence5 Laryngoscope, 129:244–255, 2019
