My nose collapses when I suck air from my nostrils. How would surgery fix that?

What you're describing is a septorhinoplasty. A small amount of deviated cartilage from the septum is placed either in the middle or lower third of the nose to prevent the collapse that you describe. This technique can be very effective in properly selected patients. This is a very common procedure. I hope this information is helpful.Stephen Weber MD, FACSDenver Facial Plastic Surgeon

There are 3 types of cartilage grafts  that are used to help with the collapsing nose with inspiration.1. Spreader grafts are composed of the patient's own septal cartilage and are inserted along the dorsal septum to push the upper lateral cartilage outward. They help with valve collapse and vestibular stenosis. This also opened up the nasal angle and internal nasal valve to improve air flow and help  the nose with collapse 2.  Alar Batten grafts are also composed of cartilage from the internal portion of the nose and are inserted at an approximately 45° angle,  placed underneath the lower lateral cartilages and inserted underneath  the pyriform aperture to hold open the collapsing lower lateral cartilages.3, Alar rim grafts are thinner cartilage grafts also harvested from internal nasal septal cartilage and are inserted right along the alar rim as a stiffening graft to prevent the alar rim from collapsing inward with inspiration.

Without
further historical information the cause of the septal deviation and the
associated nostril collapse cannot be determined. Perhaps the condition arose
as part of your natural development, perhaps from an acquired circumstance such
as trauma. Without a full physical examination of both your external nose and
your internal nasal anatomy the root of your collapsing nostrils also cannot be
determined. That said, the mid vault of the nose houses the internal nasal
valves which when deficient can definitely lead to “nostril” collapse on
inspiration. The use of septal cartilage, fashioned into the form of mid-vault
spreader grafts effectively addresses this problem. 



Your
description details your nose sucking in the skin above your nostrils, so I
must also consider that you may be referring to the lower portion of your nose which houses the
lateral alar cartilages. If collapse occurs at this level, septal cartilage may
be used in a variety of ways to support the lower wings of the nose (i.e.,
alae).



Ask
your surgeon whether mid-vault spreader grafts or lower-alar support grafts are
needed. The internet has pictorial examples of each of the aforementioned grafts. Best of luck to the you, new scientist!
