Introduction: Computational fluid dynamics (CFD) is gaining momentum as a useful mechanism for analyzing obstructive disorders and surgeries in humans and warrants further development for application in equine surgery. While advancements in procedures continue, much remains unknown about the specific impact that different surgeries have on obstructive airway disorders. The objective of this study was to apply CFD analysis to an equine head inhalation model replicating recurrent laryngeal neuropathy (RLN) and four surgical procedures.

To explore the application of spiral tracheoplasty in the repair of large tracheal defects after the resection of trachea invaded by thyroid cancer. A retrospective analysis was performed on the clinical data of 11 patients, including 4 males and 7 females, aged from 36 to 67 years old, with large tracheal defects after tracheal resection due to thyroid papillary carcinoma invading the trachea in the Department of Otorhinolaryngology Head and Neck Surgery, Second Xiangya Hospital, Central South University from January 2019 to January 2022. The range of tracheal defects, time of tracheal reconstruction, postoperative complications and airway were recorded, and the patients were followed up for more than 24 months.

Objective: To develop a reproducible survival rabbit model for laryngotracheal stenosis (LTS).
Methods: Seventy New Zealand white (NZW) rabbits were randomly divided into experimental groups ( = 30) and a control group ( = 40). In experimental groups, a nylon brush was inserted retrograde from the tracheotomy through the subglottis and rotated until a full layer circumferential mucosal injury to cartilage exposure, assisted by fiberoptic laryngoscopy (FOL) visualization.
