July 5, 2022

BATON ROUGE, LA – A team of researchers from LSU’s Department of Biological and Agricultural Engineering and the LSU Health Sciences Center-New Orleans Department of Otolaryngology recently published a paper in Laryngoscope Investigative Otolaryngology titled, “A Modular Surgical Simulator for Microlaryngoscopy Using Standard Instruments and the Carbon Dioxide Laser.”

Dr. Michael E. Dunham, faculty member in the LSU Department of Otolaryngology Head & Neck Surgery, adjunct faculty member in LSU Biological Engineering, and principal investigator on the project; co-authored the paper with Dr. Sarah Bressler (LSUHSC-NO); Dr. Lacey Adkins (LSUHSC-NO); Dr. Rohan Walvekar (LSUHSC-NO); Philip Jung, Ph.D. (LSU BE); Jorge Belgodere, Ph.D. (LSU BE); Adam Bao (LSU BE); Lizabeth Breaux (LSU BE); Hunter Lee (LSU BE); Soheil Saneei (LSU BE); Austin Veal (LSU BE); and John Carleton (BS).

In the paper, the team details how it created a modular design for a microlaryngoscopy simulator in CAD, or computer-aided design, software. Components used included plastic and stainless steel models of a standard operating laryngoscope and a cassette system for mounting synthetic models of the vocal folds with tumor phantom, which is made of natural biomaterials. All simulator parts, including the metallic laryngoscope model, were manufactured using 3D printing technology. 

The resulting microlaryngeal surgical simulator demonstrated in the project proved to be a realistic alternative, economical, and easily assembled. Participants using the simulator felt that it faithfully represented the procedure to resect vocal fold lesions using a CO2 laser and allowed trainees to develop hand-eye coordination while using standard laryngeal instruments.
