Where is nasal valve
The nasal valve is the thinnest part of the nasal passage where air passes through. The nasal valve was originally described by Mink in 1903. It is divided into external and internal portions. The external nasal valve is formed by the columella, the nasal floor, and the nasal rim (or caudal border of the lower lateral cartilage). The nasalis muscle dilates this portion during inspiration.
The nasal valve area is formed by the nasal septum, the caudal border of the upper lateral cartilage, the head of the inferior turbinate, and the pyriform aperture and the tissues that surround it. This area is responsible for more than two thirds of the resistance produced by the nose.
The internal nasal valve accounts for the larger part of the nasal resistance. It is located in the area of transition between the skin and respiratory epithelium, and it is usually the narrowest part of the nose. The internal nasal valve is the better-known as the nasal valve.
The 2 terms should be differentiated because the nasal valve accounts only for the aperture between the nasal septum and the caudal border of the upper lateral cartilage. The angle formed between them is normally 10-15Â°.
Nasal Valve Collapse
This is a condition where the sidewalls of your nostrils collapse as you breathe in.
Treatment of internal valve problems usually involves 1 of 3 methods: scar revision, medial osteotomies, or on-lay grafting of the nasal dorsum. None of these methods is free of adverse effects such as pain, bleeding, and bone necrosis.
Â Simple way to repair the Nasal Valve Collapse:
The operation was performed with local anesthesia. The vestibular skin, nasofacial sulcus, and alar rim were injected with 5 ml of ligocaine hydrochloride, 1%, with 1:100 000 epinephrine. A stair-step incision was made with a No.15 blade. The soft tissues were elevated, and the lateral crus was everted using a double-skin hook placed at the cephalic rim. A mucosal packet was then created by dissecting the vestibular mucosa from the under surface starting from the junction of the intermediate crus toward the pyriform aperture. Approximately 1 to 2mmof the caudal ULC was resected and the mucosal incision was closed with 3 interrupted 4-0 chromic sutures.
