Nasal Valve Collapse After Rhinoplasty

Key takeaways

• The nasal valves are the narrowest points in the airway; losing even a little support there causes a noticeable blockage.
• Signs: harder to breathe in than out, the side of the nose pulling in on deep breaths, and relief from breathing strips.
• It's different from normal post-operative swelling, which improves steadily over weeks to months.
• Repair uses cartilage grafts to hold the valve open, and is covered by insurance more often than cosmetic revision because it's a functional problem.

The nose has two valves, and both are narrow points where airflow is controlled:

• The internal nasal valve — inside the nose, where the upper lateral cartilages meet the septum. It's the single narrowest point in the entire airway.
• The external nasal valve — the nostril entrance, framed by the lower lateral cartilages.

Because airflow depends so heavily on these tight spots, a small loss of width or support has an outsized effect on breathing.

• Hump reduction without rebuilding the middle of the nose, letting the upper lateral cartilages fall inward — often visible as an inverted-V deformity
• Over-narrowing the tip or removing too much of the lower lateral cartilages, weakening the nostril sidewalls — often visible as a pinched tip or alar retraction
• Narrowing the bony bridge (osteotomies) too far inward
• Scar contraction over time

Some congestion after rhinoplasty is normal, and the timeline helps tell the difference:

Normal swelling Valve collapse

--- --- ---

When Worst in the first 1–2 weeks Persists or appears as healing progresses

Trend Steadily improves over weeks to months Doesn't improve, or gets worse as scar contracts

Breathing in vs. out Similar Breathing in is harder

Nasal strips Modest help Clear, noticeable relief

Deep breaths / exercise No particular change Side of the nose visibly pulls inward

If blocked breathing persists beyond about three months, or you see your sidewalls collapse when you inhale, it's worth an evaluation — you don't need to wait a full year when breathing is the concern.

• The Cottle maneuver — gently pulling the cheek outward beside the nose; if breathing improves, the valve is involved.
• The modified Cottle — supporting a specific spot inside the nose with a small instrument to pinpoint where the collapse is.
• Watching the sidewalls during normal and deep breathing.
• Nasal endoscopy to check the septum and turbinates, which can add to the blockage.
• Review of the prior surgery, ideally with operative notes.

Repair restores support at the exact point of collapse, usually as a functional revision rhinoplasty:

Where the collapse is Typical graft

--- ---

Internal valve (middle of the nose) Spreader grafts between the septum and upper lateral cartilages

External valve / nostril sidewall Alar batten grafts or lateral crural strut grafts

Nostril rim Alar rim grafts

Septoplasty and turbinate reduction are added when they contribute. Cartilage comes from the septum if enough remains, otherwise the ear or rib. Grafts are shaped to restore the airway without making the nose look noticeably different — and often improve a related cosmetic problem at the same time. For less severe cases, in-office options like the Latera implant or VivAer may be considered. See nasal valve collapse treatment for the full range.

Because valve collapse is a functional breathing problem, repair may be submitted to insurance when medically necessary and your plan includes applicable out-of-network benefits — unlike purely cosmetic revision. Documentation of symptoms, examination findings, and failed conservative measures supports the request. See insurance for functional nasal surgery.
