The nasal valve controlling the air intake to the nose is located at the entrance and inside of the nose. The angle of the nasal wing to the nasal septum and therefore the open or closed airway is closely related to the structure of the nasal valves.
In order for you to breathe healthy, nasal valves must be at the appropriate angle. Otherwise, your quality of life will decrease, especially with functional problems such as septum deviation. You will experience a large nasal congestion problem.
Nasal Valve Stenosis
Nasal valve insufficiency is the narrowing of the nasal entrance. It is caused by the curvature of the cartilaginous part of the middle wall of the nose, which we call septum, and the weakness of the cartilaginous tissue in the lateral parts. Or, due to introversion, the nasal entrance is narrowed, and nasal breathing is affected. This problem arises from the reverse inclination of the cartilage structures in the nasal wings. In addition, cartilage weakens due to aesthetic surgeries, traumas and aging. This is because it cannot withstand the vacuum effect created by the air flow.
In order to prevent this collapse, they use techniques such as supporting weak areas with cartilage pieces, correcting the cartilage angle that causes narrowing, and preventing collapse with the help of stitches.
They prefer to do the surgery with an open technique, that is, with a small incision in the lower part of the nose. They correct the curvature of the nasal cartilage. In addition to correcting the curvature, they take pieces of cartilage from areas such as the inside of the nose, behind the ear or ribs when necessary. With these parts, they support the weak cartilage structure and expand the narrowed valve area. In this way, they relax the air flow.
Why Does Nasal Valve Stenosis Occur?
Nasal valve stenosis may occur congenitally or later. Factors that cause nasal valve stenosis, which also occurs with the combination of one or more factors, can be listed as follows:
- Rhinoplasty operations you have had in the past,
- Traumas you face,
- Septum deviation,
- Weakening of the nasal sidewall with aging.
Nasal Valve Surgery
Patients who experience the above-mentioned complaints due to nasal valve stenosis can get rid of their problems with surgical application. They perform it by giving the patient local or general anesthesia. They use cartilage supports to support the nasal lateral wall to expand the nasal valve angle during surgery. Afterwards, they open the air channels in the nose by stitching.
The techniques they will use during nasal valve surgery differ if nasal valve obstruction is static or dynamic. Static obstruction is an obstruction that does not change. Dynamic obstruction is the closure of the internal and external nasal valves at low pressures.
They use opener, butterfly and spreader grafts during surgical intervention on patients with static obstruction problems. In case of dynamic obstruction, they benefit from nasal valve suspension sutures, blanket and overlay concha grafts.
They usually perform nasal valve surgery simultaneously with septoplasty, turbinate surgery, and sinusitis surgery, which they perform to restore nasal function.
For this reason, before the operation, doctors should examine patients with nasal congestion in detail and examine their intranasal structures. The surgery they perform as a result of the missing examinations is not enough to solve the end of the nasal obstruction of the patient alone.
The permanent solution of nasal valve insufficiency is surgically. The success rate is almost 100%. Apart from widening the valve angle, if there are problems in the nasal septum, nasal concha or other nasal structures, they also correct them.
Depending on the situation, they perform it under local anesthesia, sedation or general anesthesia. They usually take the nasal septum or cartilage from the ear and shape it. They place it towards the dorsum of the nose to expand the valve area. Then they fix it with stitches.
After the operation, they wear a tape on the nose and remove it after 1 week. They put small tampons in the nose for 1-2 days. Swelling occurs on the nose for about 1 month.
