RESUMO
Objectives@#. The simulation of microlaryngeal skills is rarely seen in surgical training, but it is particularly important in phonomicrosurgery. This study described and validated the laryngeal surgical simulator through surgical training. @*Methods@#. A simple and low-cost simulator was developed for the fixation of the suspension laryngoscope and porcine larynges. Twenty participants with work skills and experience did preparation before training, and performed suture and carbon dioxide (CO2) laser cordectomy for simulator evaluation. The results were proposed by the aspects of time taken for each procedure, the global rating scale, a procedure-specific assessment, and a post-simulation questionnaire. @*Results@#. All participants completed the preparation within 9 minutes and reached the conclusion that the microlaryngeal surgical simulator was helpful in improving their surgical skills. The performance of experts was superior to that of novices in both suture and CO2 laser cordectomy. @*Conclusion@#. This simulator could be easily assembled and was successfully validated by microlaryngeal surgical training both subjectively and objectively. It may be helpful to clinicians in microlaryngeal skills.
RESUMO
CONCLUSIONS: The GlideScope® Video Laryngoscope (GVL) provides a successful method for obtaining adequate visualization of the larynx in patients with difficult laryngeal exposure (DLE). Although the GVL is far from an ideal laryngoscope for laryngeal surgery because of its low image quality and narrow curved operation space, valuable concepts regarding its development can be used for designing a new laryngoscope specifically for otolaryngology. OBJECTIVE: DLE is a problem characterized by poor visualization of the larynx due to a combination of anatomic and clinical conditions. With respect to DLE, no consensus has been reached as to which alternative method should be used when direct laryngoscopy fails. This study focused on the management of DLE cases using the GVL to achieve adequate laryngeal exposure for phonosurgery. METHODS: We used the GVL in conjunction with a set of specially designed endolaryngeal instruments in six cases for which traditional rigid laryngoscopy could not provide visualization of the larynx. RESULTS: Using the GVL, full visualization of the larynx was obtained in all patients with minimal need for excessive internal or external pressure. Manipulations to remove simple lesions or perform a biopsy were carried out successfully. All of the surgeries were completed with excellent visualization and without any major complications.
