Nasal Valve Collapse — when the airway closes on inspiration.

The nasal valve comprises the narrow internal and external regions that generate most nasal resistance. Small changes in valve angle or loss of cartilage support can markedly increase airflow resistance. Identifying whether the internal mid‑vault or the external nostril rim is failing directs treatment. A focused exam and trial mechanical tests distinguish structural obstruction from mucosal causes.

Internal valve collapse affects the mid‑vault and often becomes apparent during deep inspiration or exertion. External valve collapse shows as inward motion or pinching of the nostril rim and may be visible at rest or with inspiration. Both can coexist, and the exam uses dynamic observation plus the Cottle or modified Cottle maneuver to localize the primary site. Treatment targets the anatomic site of failure while minimizing unwanted contour change.

Candidates typically report persistent mechanical obstruction despite optimized medical therapy for at least 6–12 weeks and have a positive in‑office mechanical test such as reproducible relief with an external strip or internal dilator. Objective testing such as rhinomanometry or acoustic rhinometry can strengthen the documentation when available. Significant functional impairment—exercise limitation, sleep disturbance, or inability to tolerate CPAP—also supports consideration. Prior nasal surgery or trauma does not preclude repair but changes planning and graft selection.

Patients whose obstruction is primarily mucosal and resolves with medical therapy are unlikely to benefit from structural grafting until inflammation is controlled. Active smokers without a cessation plan, medically unstable patients, or those with unrealistic cosmetic goals are typically counseled toward optimization or non‑operative options first. Frail patients or those for whom general anesthesia is contraindicated may be offered office‑based mechanical supports or staged treatments. A consultation will clarify the best path for each patient.

Diagnosis begins with dynamic inspection and the Cottle or modified Cottle maneuver to see if lateralization improves airflow. Short diagnostic trials with external nasal strips or internal dilators are performed to reproduce symptomatic relief. When uncertainty remains, objective measures such as rhinomanometry, acoustic rhinometry, or nasal peak inspiratory flow provide quantitative data. Flexible endoscopy documents internal anatomy and excludes intranasal contributors such as polyps.

Consistent relief from nasal strips or an internal dilator indicates a structural component to your obstruction but does not automatically mandate surgery. For some patients, ongoing conservative care or a daily mechanical device is acceptable. Others with persistent, activity‑limiting symptoms after a controlled trial will likely benefit from structural support with grafting. The decision is individualized at consultation, balancing functional goals, donor‑site considerations, and aesthetic trade‑offs.

Day 0–7: expect mild to moderate congestion, drainage, and localized swelling; external splints or nasal packing are managed per procedure, and pain is usually controlled with oral medications. Week 2: external splints and many sutures are typically removed; most patients return to light work and normal sleep positioning. Weeks 3–6: swelling subsides further, moderate exercise may resume with your surgeon’s approval, and grafts begin to stabilize. Weeks 6–12: functional improvement often becomes more noticeable and contour changes settle. 6–12 months: final maturation of soft tissues and graft settling continues; if donor sites were used, their healing is usually complete. Contact the office for bleeding, persistent fever, increasing pain, or signs of infection.

Internal valve repair commonly uses spreader grafts or auto‑spreader flaps to widen the internal angle and stabilize the mid‑vault. External valve reconstruction uses alar batten grafts, lateral crural struts, rim grafts, or lateral crural repositioning to reinforce the nostril rim. Choice depends on cartilage quality, prior surgery, and whether septoplasty or turbinate reduction is required. Procedures are tailored to restore support while preserving or improving nasal contour.

Autologous cartilage—septal, conchal (auricular), and costal—remains the preferred source for long‑term support. Septal cartilage is convenient when septoplasty is performed; auricular cartilage provides thin, curved material ideal for rim grafts; costal cartilage is reserved for larger reconstructions or multiple prior surgeries. Donor‑site risks vary: septal harvest risks septal perforation or hematoma if mishandled, conchal harvest can cause contour change or pain, and costal harvest requires a chest incision and carries a rare risk of pneumothorax. Your surgeon will review donor‑site trade‑offs during planning.

Risks include bleeding or hematoma (including septal hematoma), infection, graft visibility, contour irregularity, graft warping or resorption, persistent or recurrent obstruction, and the possible need for revision surgery. Anesthesia‑related risks are present as with any operation. Many complications are uncommon; surgeons mitigate them with careful technique, appropriate graft selection, and structured postoperative care. Outcomes vary between primary and revision cases, and realistic goals are set during consultation.

Insurers typically require objective documentation of functional impairment and failed conservative therapy. Useful items include a documented trial of optimized medical therapy (commonly 6–12 weeks), reproducible relief with mechanical testing (external strip or internal dilator), physical exam findings localizing valve collapse, and objective testing when available (rhinomanometry or acoustic rhinometry). Operative reports and preoperative imaging or endoscopy that confirm structural obstruction strengthen prior‑authorization requests.
