Management of N asal Valve Collapse Following Rhinoplastic Surgery
Nasal valve collapse (NVC) is a frequent\, ye t often overlooked\, complication following rhinoplasty. It affects both t he internal and external nasal valves and can lead to persistent nasal obs truction despite an otherwise successful cosmetic outcome. NVC is a signif icant and often underdiagnosed cause of postoperative nasal obstruction fo llowing rhinoplastic surgery. The incidence of NVC post-rhinoplasty is est imated at 10–15%\, though this may be underestimated due to variability in diagnostic practices.
The na sal valve area\, comprising the narrowest segment of the nasal airway\, is highly susceptible to both static and dynamic collapse\, particularly aft er structural alteration during cosmetic or functional rhinoplasty. Post-r hinoplasty NVC may result from structural weakening due to excessive carti lage resection\, inadequate support of the lateral nasal wall\, or failure to reinforce the internal valve. As the nasal valve area is critical to r egulating airflow resistance\, even minor structural changes can result in significant functional impairment.
The management strategy for NVC involves primarily prevention in the original operation. If occurs postoperatively\, objective and subjective d iagnostic methods\, such as Visual Analog Scale (VAS) for patient-reported nasal obstruction\, peak nasal inspiratory flow (PNIF) measurements\, mod ified Cottle tests\, nasal endoscopy\, and digital imaging or anatomical a ssessment are used for definite diagnosis. Non-surgical methods are tried namely\, the use of external nasal dilators strips\, trial of internal nas al stents or nasal valve dilators and medical therapy (nasal corticosteroi ds\, antihistamines) to optimize mucosal condition. These modalities\, whi le non-invasive\, are often insufficient or poorly tolerated by some patie nts due to comfort or cosmetic concerns.
Surgical correction methods may include the use of spreader graf ts\, alar batten grafts\, and suspension techniques\, tailored to the type and severity of the valve collapse. Alar batten grafts can improve the NV C\, but cause the nose look less elegant and broad. Moreover\, some patien ts feel uncomfortable due to graft rigidity on the nasal side walls.
Alternatively\, nasal valve suspensi on sutures have shown promise in addressing both internal and external NVC without compromising nasal appearance. This technique does not require ca rtilage grafts\, avoiding donor site morbidity\, utilizes a minimally inva sive endonasal approach\, and involves placement of one or two 4-0 or 5-0 PDS sutures in a horizontal mattress configuration to support the lateral nasal wall.
This surgical techn ique is indicated for patients presenting with persistent nasal obstructio n secondary to valve collapse following primary rhinoplasty. Exclusion cri teria include unresolved septal deviation\, turbinate hypertrophy unrelate d to valve dysfunction\, or active sinonasal disease. Patients were follow ed for a minimum of six months.
Postoperative outcomes were assessed using VAS scoring for subjective imp rovement\, PNIF measurements for objective airflow assessment\, modified C ottle test and nasal endoscopy\, and photographic documentation to evaluat e maintenance of aesthetic outcomes.
Nasal valve suspension sutures represent an effective and cosmetical ly favorable surgical option for managing NVC after rhinoplasty. This tech nique provides effective relief of nasal obstruction without compromising the external nasal appearance\, making it a valuable alternative to tradit ional graft-based procedures in appropriately selected patients.
