The EASE procedure was developed by Dr. Li in 2017. The objective of the operation was to maximize the nasal airway expansion while minimizing the undesired side effects. The operation focuses on the entire nasomaxillary complex, including the posterior region of the maxilla without excessive flaring of the dentoalveolar aspect.
Nasal expansion directly improves nasal respiration. The reduction of nasal resistance leads to lower airway velocity and reduced negative nasal pressure on inspiration, leading to improved patency in the retropalatal/retroglossal airway.
