Conclusion:
The rabbit model of anterior glottic web (AGW) formation using the laryngofissure technique resulted in reproducible and stable AGW formation that may facilitate research into this area.
Objective:
To introduce and validate a novel experimental animal model of AGW formation using the rabbit.
Methods:
The inner larynges of eight New Zealand white rabbits were exposed through the laryngofissure technique. The mucosa of the bilateral true vocal fold was stripped off using the bevel of a needle tip. On the basis of the laryngoscopic findings at 8 weeks postoperatively, the extent of AGW was measured, and the success of this procedure was validated. Laryngeal specimens were sampled at 8 weeks for high-speed recording and histological analysis.
Results:
In seven (87.5%) rabbits, laryngoscopic examination revealed the formation of a scar band involving the anterior commissure. The mean extent of AGW ratio on the left and right sides was 0.58 ± 0.073 and 0.55 ± 0.075, respectively. The symmetric formation of AGW (p = 0.655, p = 0.128) and stability of the AGW procedure (p = 0.491, left; p = 0.501, right) were statistically validated. On high-speed recording, the vocal mucosal wave was hindered by AGW formation. Histologically, fibro-connective tissue, especially collagen fiber, was observed in the anterior commissure.
