    Abstract Objective: Training of surgical procedures on awake patients, such as medialization thyroplasty, poses challenges to educators and trainees. Three-dimensionally (3D)-printed simulators provide opportunity to practice in low-stakes settings. We present the first 3D-printed thyroplasty simulator incorporating a cartilaginous framework, endolaryngeal soft tissue housed in a 3D-printed manikin with endoscopic visualization.
    Methods: Male and female laryngeal cartilages and endolarynx molds were 3D printed from an existing open-source design. Cartilage models were made of heat-treated polylactic acid (HTPLA), a material chosen for its thermal stability, allowing drilling. They were combined with molded silicone endolarynges modeling glottic insufficiency. Larynges were set in a 3D-printed head-and-neck manikin with an attached borescope for internal visualization similar to distal chip laryngoscopy. Eight laryngologists evaluated the simulator by drilling a thyroplasty window, inserting an implant for medialization, and rating the model using a modified Michigan Standard Simulation Experience Scale (1 = strongly disagree, 5 = strongly agree).
    Results: The model was well rated in educational value (mean 4.7, standard deviation [SD] 0.3), fidelity (mean 3.8, SD 0.2), and overall value (mean 4.8, SD 0.5). Qualitative assessment concluded the model was anatomically realistic and that HTPLA was a good approximation of the density and texture of thyroid cartilage. The materials for one larynx cost $4.09.
    Conclusion: This high-fidelity 3D-printed simulator demonstrates educational value for thyroplasty training. The low-cost, open-source design has broad implications for universal access to this simulator platform.

    Abstract Objective: Simulation may be a valuable tool in training laryngology office procedures on unsedated patients. However, no studies have examined whether existing awake procedure simulators improve trainee performance in laryngology. Our objective was to evaluate the transfer validity of a previously published 3D-printed laryngeal simulator in improving percutaneous injection laryngoplasty (PIL) competency compared with conventional educational materials with a single-blinded randomized controlled trial.
    Methods: Otolaryngology residents with fewer than 10 PIL procedures in their case logs were recruited. A pretraining survey was administered to participants to evaluate baseline procedure-specific knowledge and confidence. The participants underwent block randomization by postgraduate year to receive conventional educational materials either with or without additional training with a 3D-printed laryngeal simulator. Participants performed PIL on an anatomically distinct laryngeal model via trans-thyrohyoid and trans-cricothyroid approaches. Endoscopic and external performance recordings were de-identified and evaluated by two blinded laryngologists using an objective structured assessment of technical skill scale and PIL-specific checklist.
    Results: Twenty residents completed testing. Baseline characteristics demonstrate no significant differences in confidence level or PIL experience between groups. Senior residents receiving simulator training had significantly better respect for tissue during the trans-thyrohyoid approach compared with control (p < 0.0005). There were no significant differences in performance for junior residents.
    Conclusions: In this first transfer validity study of a simulator for office awake procedure in laryngology, we found that a previously described low-cost, high-fidelity 3D-printed PIL simulator improved performance of PIL amongst senior otolaryngology residents, suggesting this accessible model may be a valuable educational adjunct for advanced trainees to practice PIL.

    Abstract Background: Standard of care for management of thyroglossal duct cysts (TGDCs) is a Sistrunk procedure performed through a transcervical incision. We describe the first series of Sistrunk procedures performed through a transoral endoscopic vestibular approach, eliminating a visible external scar.
    Methods: The transoral endoscopic vestibular approach to the Sistrunk (TEVAS) was performed in patients with TGDCs meeting inclusion criteria who desired a scarless approach.
    Results: Six patients (five females and one male) underwent TEVAS, with a mean age of 38 years (range 16-56 years) and a mean TGDC size of 1.8 cm (range 1.1-2.4 cm). Mean operative time was approximately 5 h (range 2-8 h). There were no surgical complications or recurrences.
    Conclusions: For appropriately selected patients, the TEVAS is an alternative to open neck surgery that provides improved cosmesis while maintaining successful resection outcomes. More data on outcomes including complications and recurrences are needed as additional case information is collected.
