With the increasing number of rhinoplasty surgeries, the associated complications are becoming more and more prominent. We met a large number of patients in the outpatient clinic who had limited ventilation after rhinoplasty, and CT examination found that the nasal valve area of the nose became extremely narrow, resulting in subjective and objective restriction of ventilation, which had a great impact on the patient's life.
The reason for this is that many plastic surgeons copy Western rhinoplasty techniques, and when rhinoplasty builds a stent, it occupies a lot of nasal volume, resulting in narrowing of the internal nasal valve and restricting the patient's ventilation subjectively and objectively.
Based on the team's nearly 30 years of rhinoplasty experience, our team proposed the concept of exogenous stents, which have no effect on nasal volume and will not lead to nasal ventilation restriction. In addition, for patients who have been ventilated with restriction, we can choose to remove the previously unsuitable stent and replace it with an exogenous stent to improve the shape and function.
We have published the team's experience in a world-renowned journal in the hope of bringing benefits to more rhinoplasters and patients.
