Inferior turbinate hypertrophy caused by various reasons is a common cause of nasal ventilation, and surgery to reduce the volume of inferior turbinate is one of the methods to improve ventilation. There are various ways of inferior turbinate surgery, and the commonly used methods are as follows: 1. Fracture and external displacement of inferior turbinate: external force fractures the inferior turbinate, and the inferior turbinate moves out as a whole to widen the total nasal passage and improve ventilation. This method is simple to operate and causes little damage to the turbinate tissue. The disadvantage is that it is impossible to fix the inferior turbinate and the displaced position, and the inferior turbinate may return to its original position, leading to the narrowing of the common nasal passage again.
