Nasal valve collapse is a structural condition where the narrowest part of the nasal airway weakens and narrows, leading to difficulty breathing through the nose. This condition can affect one or both sides of the nose and is often a result of:
- Previous nasal surgery
- Trauma to the nose
- Deviated nasal septum
- Congenital structural issues
Over time, the weakening of nasal structures can lead to increased airway resistance and significant breathing difficulties.
